Bottom Line: 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.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.

ABSTRACT

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.

Figure 1: Measurement stent on cast with holes punctured at the measurement sites

Mentions: After the subject was deemed eligible, a maxillary impression was made with alginate impression material and poured in a Type III dental stone. Acrylic measurement guides (Clear Splint Biocryl, 0.5 mm thickness were then fabricated on the cast model and trimmed appropriately to include all teeth present in the arch. Using a standardized UNC-15 probe (Hu-Friedy, Leimen, Germany), measurements were made at distances of 2 mm, 5 mm, and 8 mm from the mid-palatal point of the gingival margin for the canine, first and second premolars, and the first molar on the side that was to receive palatal surgery. A hole was subsequently punctured through the acrylic stent at each measurement point [Figure 1]. Gutta-percha was used to fill each measurement site [Figure 2]. The purpose of the gutta-percha was to have a radio-opaque marker on the CBCT scan. This stent was subsequently used for all clinical and radiographic measurements.
