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目前和未来可能发生的牙列缺失后的咬合功能丧失，而且还包括与此相关的各种问题，如咬合平面的病理进展、TMJ‘s、面部高度和其他形态变化，以及由此导致的中枢和周围神经肌肉控制系统的障碍。预测这些比率和这些口腔疾病的进展，并对其进行控制，最终恢复和维持正常的功能是我们关心的问题。自有分析系统的临床试验结果在国际口腔医学大会上报道如下：咀嚼功能(咀嚼肌肉活动、乳房节律、咀嚼周期模式等)的显著改善以及与临床预后相关的RI指数(与剩余牙槽形和义齿承载能力有关)与口腔修复的预后有关。

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.
