Research On The Impact Of Orthodontic Treatment Of Gingival Recession

[Objective] Gingival recessions are defined as the displacement of themarginal tissue apical to the cemento-enamel junction and can affect the labial,lingual and/or interproximal areas, which affects the aesthetic aspects of thesmile. The aetiology of gingival recession is incompletely understood andthought to be multifactorial in nature, with both predisposing and precipitatingfactors implicated. Controversy exists in the literature between the role oforthodontic treatment and gingival recession. Some literature found thatorthodontics provided little benefit to the periodontium. While others havefound no such association. The objective of this study is to discuss therelationship between the orthodontic treatment and gingival recessions, and topresent two treatment reports that demonstrate concomitant orthodontic andperiodontal benefits.[Method] Two cases with periodontitis and severe gingival recessions wereperformed using fixed appliance to alignment the anterior teeth, put the rootsmore onto bone and to change their dental hygiene methods.[Result] After average16months of orthodontic treatment, the patients’fixed appliances were removed. The overbite and overjet had been normalized, and Class I molar interdigitation had been maintainted on the both sides. Thepatients described in these cases presentation also have2mm more rootcoverage than they had before orthodontic treatment.[Conclusion] Orthodontic treatment might improve the periodontalprognosis by correct diagnosis; perfect treatment plan; light force; maintaininggood oral hygiene throughout orthodontic treatment; eliminating potentialcauses of recession (piercing, smoking, traumatic tooth-brushing), and avoidingocclusal disturbance.
