This study aimed to measure the palatal mucosal thickness and examine the location of the greater palatine foramen using cone-beam computerized tomography (CBCT).
In this study, cone-beam computed tomography (CBCT) images of the maxillary posterior region of 120 subjects were evaluated. The palatal mucosal thickness (PMT), palatal width and depth, and location of the greater palatine foramen (GPF) were determined on CBCT. The differences in the palatal mucosal thickness according to gender and palatal width/palatal depth were analyzed. The location of the GPF related to the maxillary molars was noted.
The mean palatal mucosal thicknesses from the canine to the second molar teeth were 3.66, 3.90, 4.06, 3.76, and 3.92 mm, respectively. The mean PMT at the second premolar was statistically thicker than at other regions (p < 0,001). There was no relationship between PMT and gender. However, the palatal depth and width of the males were greater than females. (p = 0.004 and p = 0.014, respectively) PMT in the low palatal vault group had statistically higher compared to the high palatal vault group. (p = 0.023) Greater palatine foramen was mostly observed between second and third molar teeth. (48%).
According to our results, first and second premolar regions can be preferable in soft tissue grafting procedures for safe and successful treatment outcomes. The measurement of the thickness of the palatal mucosa and the evaluation of the greater palatine foramen location before the surgical procedures are essential steps to harvest from the ideal donor site and to achieve optimal surgical outcomes.
本研究旨在使用锥形束计算机断层扫描（CBCT）测量腭黏膜厚度，并检查腭大孔的位置。
本研究对 120 名受试者的上颌后区进行了锥形束计算机断层扫描（CBCT）检查。在 CBCT 上确定腭黏膜厚度（PMT）、腭宽度和深度以及腭大孔（GPF）的位置。分析了性别和腭宽度/腭深度对腭黏膜厚度的差异。注意 GPF 与上颌磨牙的位置关系。
从犬齿到第二磨牙，腭黏膜的平均厚度分别为 3.66、3.90、4.06、3.76 和 3.92mm。第二前磨牙处的平均 PMT 明显比其他部位厚（p<0.001）。PMT 与性别之间没有关系。然而，男性的腭深度和宽度大于女性。（p=0.004 和 p=0.014）低腭穹窿组的 PMT 明显高于高腭穹窿组。（p=0.023）腭大孔大多位于第二和第三磨牙之间。（48%）。
根据我们的结果，第一和第二前磨牙区域在软组织移植手术中可以是更可取的，以获得安全和成功的治疗效果。在手术前测量腭黏膜的厚度和评估腭大孔的位置是从理想供体部位获取和获得最佳手术效果的重要步骤。
