Kazanjian vs modified Kazanjian technique in mandibular anterior ridge extension

Abstract

This study was conducted to compare the efficiency between Kazanjians and modified Kazanjians technique in mandibular anterior ridge extension vestibuloplasty procedure. Thirty patients indicated for mandibular anterior ridge extension procedure were divided into two groups. Fifteen patients underwent Kazanjians technique of vestibuloplasty and the remaining underwent modified Kazanjians technique of vestibuloplasty. Vestibular depth, patient compliance and complications were reviewed and recorded on the 1st day, 1st week, 1st month and 3 months post-operatively. The immediate post-operative depth in modified Kazanjians group ranged from 10 to 15 mm, 1st week post-operatively was 10–15 mm, 1st month post-operatively was 6–15 mm and that of 3 months post-operatively was 4–12 mm. The immediate post-operative depth in Kazanjians group ranged from 11 to 15 mm, 1st week post-operatively was 9–15 mm, 1st month post-operatively was 9–14 mm and that of 3 months post-operatively was 9–14 mm. The percentage of increase in vestibular depth 3 months post-operatively in modified Kazanjians group was 164.22% and that of Kazanjians group was 183% which showed a highly significant P value of 0.008. Reviewing the results with regards to the maintenance of vestibular depth, patient compliance and complications, we recommend the Kazanjian technique of vestibuloplasty.
