摘要/Abstract

摘要： 改良唇-牙-牙槽嵴上颌全口种植义齿分类法是根据牙槽嵴宽度和高度将上颌无牙颌分为3类。Ⅰ类,牙槽嵴宽度高度均适宜,适合种植固定义齿修复;Ⅱ类,牙槽嵴宽度对于种植体足够但是对唇颊支撑不足,适合于固定活动联合修复;Ⅲ类,牙槽嵴高度或宽度不足以支撑种植体植入,需要植骨,或采用穿颧种植体等特殊方式种植,或者采用传统全口义齿修复。第Ⅰ类根据牙槽嵴高度不同又分为2个亚类：第Ⅰ类1亚类,牙槽嵴高度完全没有丧失,适合冠桥式义齿修复;第Ⅰ类2亚类,牙槽嵴高度有部分丧失,适合复合式义齿修复。本设计分类旨在帮助术者在术前明确患者是否适合种植,以及适合采用种植固定义齿还是种植活动义齿修复,有利于更好地选择适应证,减少并发症,获得更好的长期效果。

Abstract: According to the width and height of the maxillary alveolar ridge, the maxillary edentulous jaws can be divided into three categories by using modified lip-tooth-ridge (MLTR) classification. Class Ⅰ is characterized by sufficient bone available for implants in the vertical and horizontal aspects and is suitable for fixed implant-supported prostheses. Class Ⅱ is characterized by sufficient bone amount available for implants in a horizontal aspect but insufficient for lip support and is suitable for a fixed detachable implant-supported prosthesis. Class Ⅲ is characterized by inadequate amount of bone for implants (with vertical or horizontal components) and is suitable for the use of zygomatic implants or traditional complete denture. Patients belonging to Class Ⅰ can be further classified into two sub-categories according to the height of the alveolar ridge. The first subclass is characterized by minimal bone deficiency and is suitable for a conventional implant-supported “crown and bridge” prosthesis. The second subclass is characterized by a larger vertical deficiency than that of the first subclass and is suitable for implant-supported hybrid prosthesis. The MLTR classification system can help the dentist to determine whether the patient is suitable for implanting dentures and whether fixed denture or removable denture is appropriate for the patient, select indications, reduce complications, and achieve long-term results.
