A Physiological and Morphological Evaluation for Designing of Bilateral Free End Saddle Denture Occlusion

目前可摘局部义齿修复的问题不仅包括牙列缺失导致的咬合功能丧失，而且还包括与之相伴的各种问题，如咬合平面、颞下颌关节、面部高度等形态学改变的病理进展，以及由此引起的中枢和外周神经肌肉控制系统的紊乱。预测这些口腔疾病的发生率和进展，并控制它们，最终恢复和维持正常的功能是我们关注的问题。在ICP会议上报告了用自己的分析系统进行的临床试验的结果，这些结果如下：咀嚼功能（咀嚼肌活动、咀嚼节律、咀嚼周期模式等）的显著改善与临床预后相关，RI指数（剩余对牙列位置与剩余牙槽嵴形状和义齿承载能力相关）与口腔修复预后相关。

Current issues of removable partial denture prosthodontics include not only loss of occlusal functions following missing dentition at present and potentially in future, but also they include variety problems accompanied with above such as patho-logical progresses of occlusal planes, TMJ's, facial heights and other morphological changes, and resulting central and peripheral neuromuscular control system disorders. Forcasting these ratesand proceeding of these oral conditions, and controlling them and final restoring and maintaining normal functions are our concerns. The results of trial clinical experiments by own analyzing systems have been reported in ICP meetings, those are as follows ; a markedly improvements on masticatory function (masticatory musclature activities, mastcatory rhythms, chewing cycle pattern etc. and related in clinical prognosis, RI-Index (location of remaining opposing dentition related with residual ridge form and denture bearing ability) have been related prosthodontic prognosis.
