Gingival recession and adult orthodontics: A clinical evidence-based treatment proposal https://doi.org/10.1016/j.ortho.2011.09.013
The presence of a gingival recession prior to orthodontic treatment is a real problem. Patients are concerned about losing their teeth but may also complain of their unpleasant appearance or root sensitivity in the exposed area. The orthodontist is not sure whether orthodontic treatment can be performed or whether the tooth movement will not aggravate the recession and whether periodontal surgery needs to be done before or after orthodontic treatment. The aim of this paper is to present recent data from the literature and several clinical situations in adults in order to submit a treatment sequence and clarify the role of different periodontal plastic surgery root coverage procedures.

Gingival recession – or, more accurately, periodontal recession since the four components of the periodontium migrate apically – is a frequently observed clinical situation which, in a West European population, affects 60% of young people under 20 years and 90% of adults over 50 (Loë et al.) [1].

The etiology of gingival recession is often multifactorial and, according to Rodier [2], 17% of recessions have no obvious clinical etiology.

Combined orthodontic - mucogingival treatment of a deep post-orthodontic gingival recession
Giovanni Zucchelli 1 , Serena Incerti Parenti, Gino Ghigi, Giulio Alessandri Bonetti
Abstract

In this article, the interdisciplinary management of an isolated-type recession defect in a severely compromised mandibular incisor of a young post-orthodontic patient is described. The prognosis of root coverage surgery was very questionable and unpredictable due to the severe root malposition (III Miller class gingival recession).

Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie volume 80, pages 1–8 (2019) Cite this article

Results

The prevalence of gingival recession in patients with infraversion and open bite after orthodontic treatment were 80.6 and 75.0%, respectively; these values were 43.4 and 47.5% before treatment, respectively. Notably, the Miller index of gingival recession increased after orthodontic treatment (P < 0.05). The risk of gingival recession in patients with infraversion or open bite after orthodontic treatment was remarkably higher than the risk in other patients (odds ratio [OR] = 16.712 and 5.073, respectively); the gingival recession rate was related to treatment with tooth extraction (OR = 2.043), as well as gingival biotype (OR = 0.341) and gingival index (GI) before orthodontic treatment (OR = 97.404; P < 0.05).

Conclusions

Patients with these two types of low occlusal function are more likely to exhibit gingival recession after orthodontic treatment. Moreover, the prevalence of gingival recession after orthodontic treatment is higher among patients who have undergone tooth extraction during orthodontic treatment, and among those who exhibit thin gingival biotype and high gingival index before orthodontic treatment.

Management of Gingival Recession Associated with Orthodontic Treatment: A Case Report
Tarun Kumar Rana,1 Megha Phogat, corresponding author Tarun Sharma, Narayana Prasad, and Shailendra Singh

Many patients undergo orthodontic treatment for aesthetic improvement. It is well established that the patients who undergo orthodontic treatment have a high susceptibility to present plaque accumulation on their teeth because of the presence of brackets, wires and/or other orthodontic elements on the teeth surfaces with which the oral hygiene procedures might be more difficult. The orthodontic treatment is a double-action procedure regarding the periodontal tissues which may be very meaningful in increasing the periodontal health status and may be a harmful procedure which can be followed by several types of periodontal complications. There is a strong correlation between the severity and extent of gingival recessions and the orthodontic treatment suggesting that orthodontic tooth movement may lead to gingival recession. The principal objective in the treatment of gingival recession is to cover the exposed root surfaces to improve aesthetics and to reduce hypersensitivity. Different soft tissue grafting procedures have been proposed in the treatment of gingival recessions. Subepithelial connective tissue graft is a reliable method for treatment of gingival recession. The purpose of this case report was to illustrate the relationship between orthodontic therapy and gingival recession and to describe the management of this case.

The effects of orthodontic therapy on periodontal health: a systematic review of controlled evidence Anne-Marie Bollen 1 , Joana Cunha-Cruz, Daniel W Bakko, Greg J Huang, Philippe P Hujoel

Background: Orthodontic therapy has been suggested to lead to an improved periodontal status through mechanisms such as increased ease of plaque removal and reduced occlusal trauma. The objective of the authors' systematic review was to compare contemporary orthodontic treatment with no intervention, by means of evaluating periodontal outcomes measured after end of treatment.

Methods: The authors completed electronic searches in eight databases (1980-2006) and hand searches in six dental journals (1980-2006). They extracted data using standardized forms and calculated weighted mean differences.

Results: Weak evidence from one randomized study and 11 nonrandomized studies suggested that orthodontic therapy was associated with 0.03 millimeters of gingival recession (95 percent confidence interval [CI], 0.01-0.04), 0.13 mm of alveolar bone loss (95 percent CI, 0.07-0.20) and 0.23 mm of increased pocket depth (95 percent CI, 0.15-0.30) when compared with no treatment. The effects of orthodontic therapy on gingivitis and attachment loss were inconsistent across studies.

Conclusions: This systematic review identified an absence of reliable evidence describing positive effects of orthodontic treatment on periodontal health. The existing evidence suggests that orthodontic therapy results in small detrimental effects to the periodontium.


The objective of this article is to discuss the relationship between the development of a healthy periodontium and the potential impact of orthodontics, to advocate for modifications in orthodontic treatment that might improve the periodontal prognosis, and to present a treatment report that demonstrates concomitant orthodontic and periodontal benefits.

More recently, there has been discussion of a genetically based susceptibility that is manifest in various types of gingival integrity, known as biotype (thick or thin). 10

In 1977, Bernimoulin and Curilovic [11] debunked the correlation between GR and tooth mobility and the correlation between tooth mobility and alveolar bone dehiscence. While they found a positive, significant correlation between GR and bone dehiscence, they questioned the impact of trauma from occlusion.

11. Bernimoulin J, Curilovic Z. Gingival recession and tooth mobility. J Clin Periodontol. 1977; 4:107–114. https://pubmed.ncbi.nlm.nih.gov/266503/

More germane to the realm of orthodontics, recession can occur during development in the form of insufficient space for the dentition on an alveolar ridge. As the discrepancy between tooth mass and available space increases, teeth become more crowded and are ultimately pushed off the ridge, compromising the supporting bone. Thus, the likelihood of recession increases. The process begins in the form of dehiscences or fenestrations. Once these have formed, the absence of alveolar bone makes it more difficult for healthy gingival tissue to persist in the form of a protective barrier.

The hypothesis he proposed was that orthodontic movement in the direction of risk would likely exacerbate the periodontal status and cause GR. In his study, he found that more than 75% of the patients who have received premolar extraction “demonstrate clinically significant gingival recession, leading him to conclude that these patients were compromised from the outset by reduced RSBI."

Daprile et al.9 reported on a 5-year study of dental students, wherein the number of subjects with at least one site of recession increased significantly—as did the total number of foci. What's more, the percentage of affected sites increased with the level of oral hygiene education, and this increase was despite a reduction in harmful dental hygiene habits.

Of the 174 fifteen-year-olds in the sample studied by Bjorn et al.,14 an astounding 62% showed some degree of GR on the labial of maxillary teeth. Interestingly, the group with an “unspecific” toothbrushing technique had fewer lesions than the group that used the “roll or vibratory technique.” The authors speculated that the difference might not have been the technique but the fact that the unspecific group was paying less attention to their oral hygiene.

Loe et al.15 compared samples from Norway and Sri Lanka and found that more than 60% of Norwegian children had recession by age 20 (compared with 30% in Sri Lanka), and that increased to more than 90% at age 50 (compared with 100% of Sri Lankans by age 40). As the Norwegian recession was largely on the buccal and that of the Sri Lankan cohort was more generally distributed, the researchers conjectured that several factors were involved, that much of the Norwegian recession seemed to be more related to mechanical abrasion associated with excessive hygiene systems as opposed to recession caused more by periodontal disease in the Sri Lankan sample.

The Impact of Orthodontic Retainers on Gingival Recession: A Best-Evidence Review
Nada M. Souccar, DDS, MS; Rawan Oueis, DDS; John Paul Mussleman, Jr., MLIS; Nicolaas C. Geurs, DDS, MS; and Ramzi V. Abou-Arraj, DDS, MS

This best-evidence article reviews the effects of the different types of orthodontic retention appliances, fixed and removable, on the development and progression of gingival recession at the mandibular anterior teeth. Searched databases included PubMed, Scopus, Cochrane Library, Embase, and Dentistry & Oral Sciences. Eleven qualifying publications, including retrospective, prospective, and cross-sectional studies, were included in this review. These studies either did not demonstrate an association between orthodontic retainers and gingival recession or reported that the resulting recession defects were minimal when an association was shown.

An important consideration is that recession could be a late finding following the placement of a retainer and, therefore, may be incipient or absent in short-term evaluations. Prospective studies that specifically address the role that properly positioned fixed retainers may have on gingival recession are needed before a definitive conclusion can be generalized with regard to recommended retention protocols. Factors such as duration of retainer use, number of bonded teeth, and position of fixed retainers relative to their proximity to gingival tissues are not fully elucidated but may have influencing roles on gingival recession. The use of retainers should be based on orthodontic indications to maintain a stable dental arch form, esthetics, and occlusion. Effective oral hygiene and follow-up regimens remain the gold standard in maintaining periodontal health and preventing gingival recession.

Long-term post-orthodontic follow-up, spanning 10 to 20 years, has revealed that less than 30% of cases showed stability in the anterior mandibular segment with 20% of those cases showing likelihood for crowding years after retainer removal.

Gingival recession results in apical migration of the gingival tissue that leads to exposure of the root apical to the cementoenamel junction.18

Recession increases with age and equally affects individuals with high and low levels of oral hygiene.19

Recession can occur labially or lingually, is unesthetic, and can potentially lead to dentin hypersensitivity, root caries, soft-tissue discomfort, and a greater susceptibility to inflammatory insult.20 These clinically adverse conditions highlight the importance of having a proper understanding of the effects that different types of retainers can have on the prevalence of recession in the gingival tissue.

Predisposing factors that have been implicated in the development or progression of gingival recession include
— periodontitis,
— periodontal therapy,
— thin periodontal phenotype,21,22
— improper toothbrushing through increased duration, frequency, force, or brush bristle size,23,24
— presence of intracrevicular restorative margins especially in the absence of keratinized gingiva,21
— orthodontic treatment,25,26 and
— shallow vestibular depth and
— frenum position that interfere with proper plaque control.27

Several of these factors are considered to have a low level of evidence.28

26. Joss-Vassalli I, Grebenstein C, Topouzelis N, et al. Orthodontic therapy and gingival recession: a systematic review. Orthod Craniofac Res. 2010;13(3):127-141.

Fixed retainers, which are commonly used to alleviate the need for patient compliance, have been found to have no significant effect on the prevalence of recession regardless of type of wire and bonding technique.7,12,15 Furthermore, the length of retainer use can also be a confounding factor. There is no evidence that has determined an ideal retention duration; however, there is general consensus that retention is recommended for life. One study comparing the prevalence of recession in patients with long-term and short-term use of fixed retainers noted an increase in gingival recession in the long-term group.9 However, these recessions were found mostly buccally, thus weakening the association of the lingually placed fixed retainer on the occurrence of gingival recession.

Despite the general consensus, a study that compared patients with fixed retainers to patients who did not undergo orthodontic treatment had contradictory results stating that the fixed retainer significantly impacted the likelihood of recession by increasing that risk by a 4.8-fold.10 The recessions in that study were labial, and the authors noted that it was unclear whether the recessions occurred as a result of orthodontic treatment or presence of the fixed retainer.

Clinical Conclusion

Within the limitations of the reviewed studies, it is unclear whether fixed or removable orthodontic retainers affect the initiation or progression of marginal gingival recession. Factors such as duration of retainer use, number of bonded teeth, and position of fixed retainers relative to their proximity to gingival tissues are not fully elucidated but may have influencing roles on gingival recession. The use of retainers is dependent on the patient's malocclusion and should be based on orthodontic indications to maintain a stable dental arch form, esthetics, and occlusion.

Potential risks of orthodontic therapy: a critical review and conceptual framework M Wishney 1-2 Affiliations PMID: 27868202
This review examines some of the potential risks of orthodontic therapy along with their evidence base. The risks of orthodontic treatment include
— periodontal damage,
— pain,
— root resorption,
— tooth devitalization,
— temporomandibular disorder,
— caries,
— speech problems and
— enamel damage.

— повреждение пародонта,
— боль,
— резорбция корней,
— девитализация зубов,
— височно-нижнечелюстное расстройство,
— кариес,
— проблемы с речью и
— повреждение эмали.

These risks can be understood to arise from a synergy between treatment and patient factors. In general terms, treatment factors that can influence risk include appliance type, force vectors and duration of treatment whilst relevant patient factors are both biological and behavioural. Hence, the natural variation between orthodontic treatment plans and patients gives rise to variations in risk. A good understanding of these risks is required for clinicians to obtain informed consent before starting treatment as well as to reduce the potential for harm during treatment. After considering each of these risks, a conceptual framework is presented to help clinicians better understand how orthodontic risks arise and may therefore be mitigated.

Does Orthodontic Treatment Affect the Alveolar Bone Density?
Jian-Hong Yu, DDS, PhD, Heng-Li Huang, PhD, Chien-Feng Liu, DDS, Jay Wu, PhD, Yu-Fen Li, PhD, Ming-Tzu Tsai, PhD, and Jui-Ting Hsu, PhD

During orthodontic tooth movement, the alveolar bone density around the teeth was reduced. However, after a period of bone recovery, the reduced bone density recovered to its previous state from before the orthodontic treatment. However, the bone density around ∼10% of the teeth in this region could not recover to 80% of its state from before the orthodontic treatment.

Iatrogenic possibilities of orthodontic treatment and modalities of prevention
Nazeer Ahmed Meeran
Orthodontic treatment can play an important role in enhancing esthetics, function, and self-esteem in patients. However, it carries with it the risks of enamel demineralization, tissue damage, root resorption, open gingival embrasures in the form of triangular spaces, allergic reactions to nickel, and treatment failure in the form of relapse. These potential complications are easily avoidable by undertaking certain precautions and timely interventions by both the orthodontist and the patient. The orthodontist must ensure that the patient is aware of the associated risks and stress the importance of the patient's role in preventing these untoward outcomes. The decision whether to proceed with the orthodontic treatment is essentially a risk-benefit analysis, where the perceived benefits of commencing treatment outweigh the potential risks. This article provides an overview of the iatrogenic possibilities of orthodontic treatment and the role of the patient as well as the orthodontist in preventing the associated risks.

Decalcification

Shannon[3] recognized orthodontic patients to be at a higher risk of decalcification or caries. An orthodontic appliance could not, within itself, be a cause of caries. However, oral hygiene problems do occur when fixed appliances are worn. Meticulous attention to oral hygiene is mandatory during the entire treatment period to avoid the risk of enamel decalcification. Banded or bonded teeth, exhibited significantly more white spot lesions compared to the controls without braces.[4] Ogaard[5] noticed that even 5 years after completing the treatment, orthodontic patients had a significantly higher incidence of enamel opacities than untreated controls.

ENAMEL FRACTURES DURING DEBONDING

Improper debonding of orthodontic brackets, particularly ceramic brackets, can result in enamel surface cracks.[25] They can provide stagnation areas for the development of caries, cause partial tooth fracture, or may cause unaesthetic discoloration. Zachrisson[25] found higher prevalence of cracks in debonded teeth compared to untreated teeth. There were appreciably more cracks with chemically bonded ceramic brackets.[26]

In many orthodontic patients, the principal reason for the associated gingival and periodontal inflammation involves mechanical irritation caused by the band or cement, in addition to trapped plaque.[36,37] The risk of attachment loss can be anticipated when such iatrogenic irritations are present.[38]

preexisting untreated periodontal disorders, fixed orthodontic appliances and tooth movement can contribute to significant and permanent periodontal damage.[40]

Gingival Recession

Gingival recession has been known to occur as an adverse effect during the orthodontic treatment or after treatment completion and has been noted more frequently during buccal orthodontic tooth movements.[62] If teeth having thin tissue are going to be moved lingually, there is a potential for the tissue to move coronally and become thicker.[63] It is generally advisable to monitor areas of thin gingival tissues periodically as the width of the attached gingiva generally increases with normal growth from the mixed to the permanent dentition.[64]

It has been found that most cases of gingival recession which occur during an orthodontic treatment occurred in the regions of the upper and lower anterior teeth.[65,66,67] The relationship between orthodontic movements and gingival recession has been controversial in relation to tipping movements. Batenhorst et al.[68] found an association between gingival recessions and orthodontic tipping tooth movements of the lower incisors in monkeys. However, other studies revealed no association between gingival recession or mucogingival defects after orthodontic tipping of the incisors.[69,70]

Black Triangles

Black triangle or open gingival embrasure can occur as potential complication in about than 1/3 of all adult orthodontic patients and should be discussed with patients prior to initiating orthodontic treatment.[73,75]

ROOT RESORPTION

A genetic predisposition to root resorption has been recognized recently.[83] Decreased IL-1 production in the case of IL-1B allele 1 may result in relatively less catabolic bone modeling (resorption) at the cortical bone interface with the PDL, which may result in prolonged stress concentrated in the root of the tooth, triggering a cascade of fatigue-related events subsequently leading to root resorption.[83]

PULP DAMAGE AND LOSS OF TOOTH VITALITY

Various studies of changes in pulp tissue vascularity during orthodontic treatment, suggest that blood flow to the dental pulp decreases initially after orthodontic force application. However, it increases thereafter until it reaches a peak 7 days after the application of orthodontic force.[93,94,95,96] These processes, depending on the degree of their disturbances, may cause changes in the metabolic cell activity, cell damage, or defense reactions. Orthodontic forces affect the dental pulp inducing vascular changes that are inflammatory in nature.[97,98] As demonstrated in the rat model, the inflammatory vascular reactions subside within 3 weeks in all tissues.[93,96]

Orthodontic patients may suffer from transient pulp ischemia, causing pain, and discomfort in the first few days after activation of an appliance. This usually settles within a week although pulp death following orthodontic treatment is occasionally reported.[99]

ACCIDENTAL SWALLOWING OF APPLIANCE COMPONENTS

ALLERGIC REACTIONS FROM ORTHODONTIC APPLIANCES

PROLONGATION IN THE TREATMENT DURATION

TREATMENT FAILURE AND RELAPSE

Failure to complete a course of orthodontic treatment is frustratingly common[159] (4-23%). This may either be due to the patient's insistence on removing the appliance earlier for personal reasons like marriage or the orthodontists’ opinion that further continuation of treatment may jeopardize the health of the dentition and the periodontal ligament, in the face of severe root resorption. Sometimes the patient might not be able to maintain oral hygiene in a satisfactory way as expected, resulting in worsening of the periodontal problem and the incidence of white spot lesions, requiring early appliance removal.[159]

Is Inflammation a Friend or Foe for Orthodontic Treatment?: Inflammation in Orthodontically Induced Inflammatory Root Resorption and Accelerating Tooth Movement
Masaru Yamaguchi 1, Shinichi Fukasawa 1 Affiliations PMID: 33673606 PMCID: PMC7957544 DOI: 10.3390/ijms22052388
On the contrary, regional accelerating phenomenon (RAP) occurs after fractures and surgery such as osteotomies or bone grafting, and bone healing is accelerated by increasing osteoclasts and osteoblasts. Recently, tooth movement after surgical procedures such as corticotomy, corticision, piezocision, and micro-osteoperforation might be accelerated by RAP, which increases the bone metabolism. Therefore, inflammation may be involved in accelerated OTM (AOTM). The knowledge of inflammation during orthodontic treatment could be used in preventing OIIRR and AOTM.

Comparing the difference between T0 and T2 (before and after orthodontic treatment) confirmed that the bone density around the teeth remained mostly constant (0.75% mean reduction). However, the bone density around ∼11% of the teeth in this region failed to recover to only 80% of its original state.

Conclusions: Corticotomy-assisted orthodontic arch expansion does not have a negative effect on the periodontium in long-term observations.

Clinical relevance: Orthodontic arch expansion can lead to bone dehiscence and gingival recession. Long-term observations revealed that corticotomy-assisted orthodontic expansion of the upper arch is not followed by negative changes in periodontal status.

Conclusion: Based on the findings of the meta-analyses, the localized use of a corticotomy can significantly increase the amount of canine distalization during orthodontic treatment. Additionally, the use of a corticotomy as a part of a PAOO procedure significantly increases the rate of orthodontic tooth movement and it is accompanied by an increased buccal bone thickness and bone density compared to patients undergoing a conventional orthodontic treatment.

There was no difference in the long-term caries experience of South Australians aged 30 years based on past orthodontic treatment. Our study does not support the contention that those treated orthodontically have better dental health later in life.
