【 摘 要 】

Introduction: Good alveolar ridge is a prerequisite forsuccessful conventional/ implant supported partial/completedenture. Extensively resorbed ridges with shallow vestibule andhigh insertion of muscles in to the ridge crest, leads to failureof prosthesis. Success of prosthesis depends on surgicalrepositioning of mucosa and muscle insertions, which increasesthe depth of vestibule and denture flange area for retention.So, the study was planned to provide good attached gingivawith adequate vestibular depth using Modified KazanjianVestibuloplasty (MKV).Aim: To evaluate efficacy of MKV technique for increasingvestibular depth in anterior mandible so that successfulprosthesis can be delivered. Efficacy of the techniquewas evaluated through operating time required, vestibulardepth achieved, scarring or relapse and any postoperativecomplications associated with the healing.Materials and Methods: Total of 10 patients were included inthe study, who had minimum 20mm of bone height and lessthan 5mm of vestibular depth for MKV procedure. The resultswere tabulated and statistical analysis was carried out to assessvestibular depth achieved i.e. from crest of the ridge to junctionof attached mucosa both pre and postoperatively. The studyresults were compared with existing literature.Results: Healing of raw surface was uneventful with satisfactoryachievement of vestibular depth. The average gain in vestibulardepth was 11 mm. The patients had good satisfaction index forprosthesis.Conclusion: Even in the era of implant prosthesis ModifiedKazanjian technique is worth to practice to achieve goodresults and overcorrection is not required as that of standardKazanjian technique. It provides adequate attached gingiva forsuccessful prosthesis. Extension of vestibular depth enablesfabrication of better denture flange with improved oral hygiene.This technique does not require hospitalization and additionalsurgery for grafts.
