Abstract

Objective:

Stereophotogrammetry (SPT) is a method in which three-dimensional coordinates

are calculated from multiple two-dimensional projections. The purpose of this study was to

compare the surface area changes between the secondary healing and grafting vestibuloplasty

techniques in the mandible by using a stereophotogrammetric technique (SPT).

Patients and Methods:

Thirteen patients were included in this study: six patients were managed

by using full-thickness skin or palatal mucosa grafts (two full-thickness palatal mucosal grafts

and four full-thickness skin grafts); the remaining seven patients, who did not accept a second

surgery for graft harvesting, underwent secondary epithelization vestibuloplasties. Postoperative

changes of surgical areas were measured by using SPT.

Statistical Analyses:

The Wilcoxon (intragroup comparisons) and Mann-Whitney U (intergroup

comparisons) tests were used for analysis of data.

Results:

In the grafting vestibuloplasty group, the surface area gain was statistically significant

(P < 0.05). In the secondary epithelization vestibuloplasty group, there was no significant

difference (P > 0.05), with even decrease of surface area being noted in some cases.

Conclusion:

SPT is a valid method for measurement of intraoral soft tissue changes.
