项目摘要

The mandibular alveolar ridge extension method by implantation with the artificial material (porous hydroxyapatite particles) is a surgical technique to extend the alveolar ridge up to the required level.From the prosthodontic point of view. this study was planned to establish the clinical technique on the implantation with the artificial materials the complete denture construction after the operation and the adjustment of denture.First, we reporeted the method using porous hydroxyapatite particles to obtain the favorable alveolar ridge shape with the surgical splint and this method gave good results.Then, as prosthodontic fundamental studies on alveolar ridge extention method, we investigated the distribution of pressure on alveolar ridge model with various thickness of mucosal simulation and the properties of mucosa in subject on recovery condition of mucosa after removing the load.Results :1. When the mucosa was the different thickness, the alveolar ridge shape was good condition. the distribution of pressure on the alveolar ridge was difference.2. The properties of mucosa on recovery condition after removing the pressure in subects, measuring parts and aging group were different.3. It became clear the mocosal properties between the aged and the young were different.4. We obtained the clinical suggestion on the construction of complete denture after the alveolar ridge extension method by implantation the artificial material and the adjustment of denture.

人工材料（多孔羟基磷灰石颗粒）植入下颌牙槽嵴延长术是一种从口腔修复学的角度将牙槽嵴延长到所需水平的手术技术。本研究旨在建立人工材料种植、术后全口义齿构建和义齿调整的临床技术，首先报道了利用多孔羟基磷灰石颗粒在外科夹板上获得良好牙槽嵴形态的方法，取得了良好的效果，然后作为牙槽嵴延长方法的修复基础研究，研究了不同厚度的模拟牙槽嵴模型上的压力分布以及受试者牙槽嵴模型上的牙槽嵴模型在去除载荷后牙槽嵴模型上的牙槽嵴恢复情况。不同厚度的牙槽嵴黏膜均能保持良好的形态。牙槽嵴上的压力分布不同.受试者、测量部位和老化组在减压后恢复状态下的粘膜性质不同.老年人和年轻人的蚊子特性明显不同。通过人工材料的植入和义齿的调整，获得了牙槽嵴延长法后全口义齿修复的临床建议。
