The aim of this study was to determine whether a condition similar to Combination Syndrome occurs in patients rehabilitated with a maxillary complete denture opposing a mandibular implant-supported fixed prosthesis.
Standardized clinical procedures measured fit, occlusal integrity, and bone loss in the anterior maxilla in 11 edentulous subjects meeting these requirements, from the patient pool of the Implant Centre, United Dental Hospital, Sydney.
A mean annual loss of 0.17 mm in the anterior maxillary ridge height was not statistically significant (P > 0.05). However, increased pressure in the anterior maxillary ridge during occlusion and loss of posterior occlusal contacts in retruded position were noted on one or both sides in all subjects.
Loss of posterior occlusion could not be related to anterior maxillary bone loss. However, to maintain the integrity of the prostheses and their supporting structures, it is important to schedule periodic recall appointments for review of the occlusion.
本研究的目的是确定在使用上颌全口义齿对抗下颌种植体支持的固定修复体进行修复的患者中，是否会出现类似于联合综合征的情况。
从悉尼联合牙科医院种植中心的患者群体中，选取11名符合这些要求的无牙颌受试者，采用标准化临床程序测量上颌前部的贴合度、咬合完整性和骨质流失情况。
上颌前部牙槽嵴高度平均每年流失0.17毫米，差异无统计学意义（P>0.05）。然而，所有受试者中一侧或双侧均出现咬合时上颌前部牙槽嵴压力增加以及后退位时后牙咬合接触丧失的情况。
后牙咬合丧失与上颌前部骨质流失无关。然而，为保持修复体及其支持结构的完整性，安排定期复诊以检查咬合情况很重要。
