The positioning of denture teeth in a completely edentulous patient is dependent on many factors. Anatomic landmarks are frequently valuable in complete denture fabrication. The topography of the palatal soft tissue in relationship to tooth position in dentate patients may be an aid in the placement of denture teeth. By using casts formed from irreversible hydrocolloid impressions, 50 subjects were examined to determine the orthographic distance from the posterior of the incisive papilla to a line intersecting the distal contact points of the maxillary canines. In 92% of subjects the posterior point of the incisive papilla was approximately 3 mm anterior to the line between the distal points of the canines. Neither gender, age, nor maxillary tooth arch form affected this distance.
全口无牙患者义齿牙齿的排列取决于多种因素。解剖标志在全口义齿制作中常常具有重要价值。在有牙患者中,腭部软组织的形态与牙齿位置的关系可能有助于义齿牙齿的排列。通过使用由不可逆水胶体印模制成的模型,对50名受试者进行检查,以确定切牙乳头后部至与上颌尖牙远中接触点相交的线的垂直距离。在92%的受试者中,切牙乳头的后部大约位于尖牙远中两点连线前方3毫米处。性别、年龄和上颌牙弓形态均不影响这一距离。
