Good alveolar ridge is a prerequisite for successful conventional/ implant supported partial/complete denture. Extensively resorbed ridges with shallow vestibule and high insertion of muscles in to the ridge crest, leads to failure of prosthesis. Success of prosthesis depends on surgical repositioning of mucosa and muscle insertions, which increases the depth of vestibule and denture flange area for retention. So, the study was planned to provide good attached gingiva with adequate vestibular depth using Modified Kazanjian Vestibuloplasty (MKV).

To evaluate efficacy of MKV technique for increasing vestibular depth in anterior mandible so that successful prosthesis can be delivered. Efficacy of the technique was evaluated through operating time required, vestibular depth achieved, scarring or relapse and any postoperative complications associated with the healing.

Total of 10 patients were included in the study, who had minimum 20mm of bone height and less than 5mm of vestibular depth for MKV procedure. The results were tabulated and statistical analysis was carried out to assess vestibular depth achieved i.e. from crest of the ridge to junction of attached mucosa both pre and postoperatively. The study results were compared with existing literature.

Healing of raw surface was uneventful with satisfactory achievement of vestibular depth. The average gain in vestibular depth was 11 mm. The patients had good satisfaction index for prosthesis.

Even in the era of implant prosthesis Modified Kazanjian technique is worth to practice to achieve good results and overcorrection is not required as that of standard Kazanjian technique. It provides adequate attached gingiva for successful prosthesis. Extension of vestibular depth enables fabrication of better denture flange with improved oral hygiene. This technique does not require hospitalization and additional surgery for grafts.
