摘　　要：目的:利用上颌结节种植搭桥术,解决上颌后牙区多颗牙缺失、牙槽嵴过度吸收、且不宜或不愿做上颌窦提升植骨的患者的种植修复需求。方法:对游离端多颗后牙缺失、牙槽嵴严重萎缩的患者。采用CDIC系统的柱状组合式种植体,在上颌结节区种植,半年后联种植体烤瓷桥修复。结果:上颌后牙区牙槽嵴顶过度吸收,上颌窦的过度气化及骨质疏松。常导致上颌后牙区的骨量严重不足,甚至仅存上颌窦底壁,不宜做上颌窦内提升植骨。而做上颌窦开放式提升植骨术,手术步骤较复杂、时间较长,术后患者局部肿胀、疼痛,同时人工骨的费用也增加了患者的经济负担。这些问题均使种植术在上颌后牙区的临床应用中受到很大限制。各国学者纷纷围绕上颌后牙区的骨量不足及骨质疏松问题展开了全面的研究,取得了积极的进展。本文所述的上颌结节区种植搭桥术解决了严重骨萎缩又要求固定修复患者的迫切要求。该方法相对于上颌窦提升植骨术有创伤小、疗程短、费用低、操作简便、患者痛苦小、接受率高等优点。结论:上颌结节区种植搭桥术不失为一种有效的方法。随着口腔种植医师的更多研究与应用,该技术将更成熟的运用于临床。讨论:关于上颌结节区的骨质疏松及种植体植入的方向和角度。都是需要进一步研究和关注的问题。Objective:To solve the patients demandings of implanting restoration whose multiple teeth has been missed in the postenor maxillarv and over resorpted. Of the crest of alveolar ridge ,in the same time，not been suitable or agreed to apply maxillary sinus lift by taking the use of the bridge on the fixture implanting in the maxillary nodules. Method:Implanting the CDIG multiple-parts implant in the the maxillary nodules,where multiple teeth has been missed in the distal-extension and over resorpted of the crest of alveolar ridge,the conectted metal porcelain crow were restorated after an haf year. Results:The over resorption of crest of alveolar ridge of posterior maxillary , the gasification of maxillary sinus and bone osteoporosis usually led the bone deficiency , even。owned the maxillary sinus base wall,wlrich is not suitable to graft Gone by maxillary sinus lift.But there，some problems of the openning maxillary sinus lift such as the complexed suegry procedure.the long perid and postoperative the patient will be serious swelling and pain，in the same time ,the artificial bone wilt be expensive. These problems largely limited the application of implant in the posterior maxillary.Many academics make comprehensive research on the bone deficiency and bone osteoporosis of posterior maxillary，and made positive progress. 1'he technique of making bridge on the fixture implanting in the maxillary nodules. Can solve the resorption of alveolar and meet the demand of the patients fixed restoration. Compared to maxillary sinus lift this method have more advantages such as little trauma, short cycle ,low cost ,simple procedure,little pain and easy to accept. Conclusions: Make bridge on the fixture implanting in the maxillary nodules is a an efficient method.With the physician oral planting more research and application, the technology will be applied more mature. Discussion :About the maxillary nodules osteoporosis and planting implants direction and Angle need further research and concern.
