A 39-year-old female patient was admitted with mobility of maxillary anterior fixed partial denture. She was diagnosed as severe chronic periodontitis of abutment teeth of the denture, left alveolus cleft, and anterior/posterior crossbites. The crossbites were improved by prosthetic approach using an implant-supported fixed partial denture with a removable gingival veneer at the anterior and crowns at the posterior. The implant-supported fixed partial denture and most teeth have been kept in a stable condition.
Sufficient lip support and proper phonetic function were recovered by implant-supported fixed partial denture with removable gingival veneer. The long-term stability of implants may be due to easiness of toothbrushing and connection of implants rendered by the fixed prosthesis.
This case suggests that implant-supported fixed partial denture with removable gingival veneer could be useful for severe ridge resorption.
一名39岁女性患者因上颌前牙固定局部义齿松动入院。她被诊断为义齿基牙重度慢性牙周炎、左侧牙槽嵴裂以及前后牙反合。通过使用种植体支持的固定局部义齿修复，在前牙区采用可摘牙龈贴面，后牙区采用全冠修复，改善了反合情况。种植体支持的固定局部义齿和多数牙齿一直保持稳定状态。
采用带有可摘牙龈贴面的种植体支持固定局部义齿恢复了足够的唇部支撑和正常的发音功能。种植体的长期稳定性可能归因于刷牙方便以及固定修复体对种植体的连接作用。
该病例表明，带有可摘牙龈贴面的种植体支持固定局部义齿对于严重牙槽嵴吸收可能是有效的。
