前牙缺失伴仃牙嵴破坏过多时,若以常规固定义齿修复,在外观和口腔卫生方面都很难达到要求,且又不易保持稳定。因此设想直接用与缺隙邻接的基牙作固定义齿的支持,桥体部分则设计为活动义齿,形成固定—活动义齿。这种义齿覆盖组织少,人工牙的排列可以满足美观要求,能补偿软组织缺损,容易保持清洁。 Loss of anterior teeth with Dingding crest destruction too much, if the conventional fixed prosthesis, the appearance and oral health are difficult to meet the requirements, and not easy to maintain stability. Therefore, it is envisaged to use the abutment abutting against the missing gap directly for the support of the denture, and the bridge part is designed as a movable denture to form a fixed-movable denture. This denture cover less tissue, artificial teeth arranged to meet the aesthetic requirements, can compensate for soft tissue defects, easy to keep clean.
