Comparative Clinical and Radiographical Evaluation of Treatment of Angular Bone Defect Related to Over Erupted Tooth Using GTR Followed by Orthodontic Intrusion Versus Orthodontic Intrusion Followed by GTR

Controlled Split Mouth Study of Effect of Orthodontic and Guided Bone Regeneration on Angular Bone Loss of Over-erupted Tooth

Summary

Occlusal prematurity leading to loss of vertical stopping points between teeth can lead to teeth over eruption creating abnormal contact area which favors food accumulation and plaque retention. All these factors can lead to gingival inflammation and bone loss which may be worsen by abnormal occlusal force. Thus, orthodontic evaluation and treatment with periodontic therapy is mandatory to achieve proper treatment. Aim of the work: To evaluate and compare clinically and radiographically between effect of guided tissue regeneration (GTR) followed by orthodontic intrusion versus orthodontic intrusion followed by GTR in treatment of over erupted tooth with angular bone loss

Detailed description

Abstract Occlusal prematurity leading to loss of vertical stopping points between teeth can lead to teeth over eruption creating abnormal contact area which favors food accumulation and plaque retention. All these factors can lead to gingival inflammation and bone loss which may be worsen by abnormal occlusal force. Thus, orthodontic evaluation and treatment with periodontic therapy is mandatory to achieve proper treatment. Aim of the work: To evaluate and compare clinically and radiographically between effect of guided tissue regeneration (GTR) followed by orthodontic intrusion versus orthodontic intrusion followed by GTR in treatment of over erupted tooth with angular bone loss Material and methods: Twenty teeth in ten cases were selected with at least two teeth with vertical over eruption and angular bone loss with presence of their opposing for spilt mouth study aged from 20- 35 years old. In group 1 (G1), ten teeth over erupted with angular bone loss were treated by GTR followed by Orthodontic intrusion whereas, in group two (G2) ten teeth over erupted with angular bone loss were treated by orthodontic intrusion followed by GTR. All cases were evaluated clinically for pocket depth (PD), bleeding on probing (BOP), tooth mobility prior starting phase one therapy, at re-evaluation and at six- and 12-months post starting either GTR or orthodontic intrusion. Also, radiographical evaluation was assessed using CBCT scan at end of re-evaluation, at six- and 12-months post starting either GTR or orthodontic intrusion to evaluate amount of orthodontic intrusion, amount of change of bone area and length related to angular defect in both groups.
