Background:
The palatal masticatory mucosa is the main donor area of soft tissue and connective tissue grafts used for increasing the keratinized mucosa around teeth and implants, covering exposed roots and increasing localized alveolar ridge thickness. The aim of this study was to compare the thickness of the palatal masticatory mucosa as determined on a cone-beam computerized tomography scan versus thickness determined via bone-sounding.
Materials And Methods:
A total of 20 patients requiring palatal surgery participated. Thickness of the palatal tissue was measured at various points radiographically and clinically. The two techniques were compared to determine the agreement of the two measurement modalities.
Results:
Statistical analysis determined that there was no significant difference between the two methods. Moreover, the tissue thickness was shown to increase as the distance from the gingival margin increased, and the tissue over the premolars was thicker than the other teeth.
Conclusion:
Cone-beam computerized tomography can be used as a noninvasive method to accurately and consistently determine the soft tissue thickness of the palatal masticatory mucosa with minimal bias at different locations on the palate.
