近几年来骨性结合种植体支持式覆盖义齿或固定义齿已成功地应用于临床来恢复无牙下颌的功能,但是迄今还没有人对在这种修复情况下,其对颌即无牙上颌骨的吸收进行过评估。本研究的目的是根据颌骨全景片资料(OPT),在三种不同的下颌修复方式下,对上颌戴传统全口义齿患者的上颌前、后部牙槽嵴的吸收进行检测和纵向研究。 研究对象为44名无牙颌患者,至少失牙2年以上,多数失牙10年以上。所有患者上颌均戴粘膜支持式全口义齿。下颌的三种修复方式分别为①由有杆连接的两个种植体支持的覆盖义齿(ODi);②由4～6个
In recent years, orthopedic or implant-supported overdentures or fixed dentures have been successfully applied clinically to restore the function of an edentulous jaw, but no one has yet done any research on this kind of restoration, The absorption was evaluated. The purpose of this study was to investigate and longitudinally study the absorption of the maxillary anterior and posterior alveolar ridges in patients with maxillofacial maxillary complete dentures under three different mandibular repair modalities based on jaw panoramic data (OPT). Study of 44 patients with edentulous jaw, at least 2 years loss of teeth, most lost more than 10 years. All patients had a mucosal-supported complete denture on the upper jaw. The three methods of mandibular repair are ① the overdenture (ODi) supported by the two implants connected by the rod,
