摘　　要：背景:全上颌骨缺失多以上颌赝复体进行修复,其中,最困难的问题是赝复体难以获得良好的固位和支持,种植体在颧骨区的应用为解决此棘手问题提供了途径。然而,在颧骨区行种植术时,有可能损伤周围组织并导致种植失败。目的:测量颧骨区骨性结构,为颧骨区种植术提供参考依据。设计:以颅骨标本为研究对象,随机抽样的重复观察测量。单位:一所军医大学口腔医学院修复科和人体解剖教研室。对象:2002-03/05在解放军第四军医大学人体解剖教研室完成。成人干燥颅骨标本(由第四军医大学人体解剖教研室提供)73个,男性标本38个,女性标本35个。方法:以游标卡尺等测量工具对73例标本进行实体定量测量,对测量结果进行统计学t检验。主要观察指标:颧骨区骨厚度,颧骨体下部宽度,颧骨体长度,颧骨体下部与眶下壁距离。结果:①由颧骨内下缘向其外上方,骨厚度逐渐减小,测量结果为:男性:距颧骨内下缘10,12,14,16mm处,骨厚度均值上半区分别为:6.97,6.45,5.75和5.01mm;下半区分别为:7.03,6.69,6.28和5.89mm。女性:距颧骨内下缘4,6,8,10mm处,骨厚度均值上半区分别为:6.95,6.55,6.28和5.31mm,下半区分别为:6.60,6.39,6.26和5.75mm。②男女颧骨体下部宽度均值分别为21.39,17.20mm。③男女颧骨长度均值分别为21.12,19.58mm。④男女颧骨体?BACKGROUND:The rehabilitation of maxillary loss is based on maxillary prosthesis,and the most difficult problem is that retention and support of maxillary prosthesis can hardly be achieved.The employment of implants in the zygoma region provides good basis for the retention and support of maxillary prosthesis.However,during implantation in the zygoma the peripheral tissues may be injured,and even induce failed implantation.OBJECTIVE:To study the bone structure of the zygoma so as to provide reference for implantation in this region.DESIGN:Randomized sampling for repeated observation measurement based on maxilla specimens.SETTING: The research was completed in the prosthodontic department of stomatological college and department of human anatomy of a military medical university.PARTICIPANTS:The experiment was carried out in the Department of
