腭部被认为是牙科外科手术的组织移植物供体。因此，本研究的目的是研究腭大动脉、腭大孔和切开颅窝等腭部结构的解剖，以便在计划移植物尺寸时考虑它们的地形，减少腭大动脉损伤的潜在风险。对41具泰国身体进行了直接检查。结果表明，男女上颚长度差异有统计学意义(p=0.017)，但垂直测量值在受检人群中分布均匀。腭大孔主要位于腭部至第二磨牙(35.7%)，女性主要位于第二、第三磨牙近中(35.7%)，男性主要位于腭部至第二磨牙(65%)。女性GPA在第一前磨牙水平分叉最多(38%)，在第一、第二磨牙水平分叉最多(43%)。男性牙槽突侧分支多见于第一、第二前磨牙水平(56%)，第二、第三磨牙水平(32%)。在上颌第一前磨牙和第二磨牙之间的区域，似乎可以获取高度至少为5 mm的结缔组织移植物。本研究的结果将为其他的比较研究提供有用的数据，并为牙周科医生计划上皮下结缔组织的大小和从上颌骨中获取移植物提供有用的数据。
Palate is considered as a tissue graft donor site for dental surgical procedures. Therefore, the aim of this study was to investigate the anatomy of palatal structures, such as greater palatine artery, greater palatine foramen, and incisive fossa, in order to consider their topography at planning the graft dimensions and reduce the potential risk of injury of greater palatine artery. Direct inspection of 41 Thai cadavers was performed. The results showed the statistically significant differences as for the length of female and male palates (p = 0.017); however, vertical measurements were equally distributed in examined population. Main location of greater palatine foramen was palatal to the second molar (35.7%), as well as, interproximal to the second and third molars (35.7%) in women, and palatal to the second molar in men (65%). GPA was branching most frequently at the level of first premolar (38%) and at first and second molars together (43%) in women. In men, the branching on the alveolar process side was commonly observed at the level of first and second premolars together (56%), and at the level of second and third molars together (32%). In the area between maxillary first premolar and second molar, it appeared possible to harvest a connective tissue graft measuring at least 5 mm in height. The results of this research will provide the useful data for other comparative studies and for assisting periodontologists in planning the dimensions and harvesting the subepithelial connective tissue grafts from palate.
