Alveolar ridge augmentation by connective tissue grafting using a pouch method and modifi ed connective tissue technique:A prospective study

Ashish Agarwal, Narinder Dev Gupta


Background: Localized alveolar ridge defect may create physiological and pathological problems.

Developments in surgical techniques have made it simpler to change the confi guration of a ridge

to create a more aesthetic and more easily cleansable shape. The purpose of this study was to

compare the effi cacy of alveolar ridge augmentation using a subepithelial connective tissue graft in

pouch and modifi ed connective tissue graft technique.

Materials and Methods: In this randomized, double blind, parallel and prospective study,

40 non-smoker individuals with 40 class III alveolar ridge defects in maxillary anterior were

randomly divided in two groups. Group I received modifi ed connective tissue graft, while

group II were treated with subepithelial connective tissue graft in pouch technique. The defect

size was measured in its horizontal and vertical dimension by utilizing a periodontal probe in a

stone cast at base line, after 3 months, and 6 months post surgically. Analysis of variance and

Bonferroni post-hoc test were used for statistical analysis. A two-tailed P < 0.05 was considered

to be statistically signifi cant.

Results: Mean values in horizontal width after 6 months were 4.70 ± 0.87 mm, and 4.05 ± 0.89 mm

for group I and II, respectively. Regarding vertical heights, obtained mean values were 4.75 ± 0.97

mm and 3.70 ± 0.92 mm for group I and group II, respectively.

Conclusion: Within the limitations of this study, connective tissue graft proposed signifi cantly

more improvement as compare to connective tissue graft in pouch.
