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
Condition: Bone Loss; Occlusion
MeSH terms: Bone Diseases, Metabolic
Study type: Interventional

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.
