摘要

全口嚴重牙周炎患者常因爲部分缺牙、咬耗之咬合塌陷或因病理性位移而有殘存齒傾倒的情形，可能引發咬合傷害及口腔衛生控制不易，進而危及搖搖欲墜的齒列。本文報告二位羅患全口嚴重牙周炎的患者，在無望齒拔除前後發生咬合塌陷及殘存齒傾倒的病例，經由遠心端無牙區之迷你骨釘對遠心端支台齒所提供的良好錨定，傾倒的支台齒得以快速扶正並加入牙周補綴物中，使殘存齒免於進一步的咬合傷害。迷你骨釘充當矯正錨定操作簡單，置入骨中即可提供矯正治療中穩定的錨定，可以在嚴重牙周炎患者的咬合重建上提供很大的幫助。

Severe periodontally involved patients frequently have reduced number of natural teeth, acquired malocclusion and bite collapse, that the remaining dentition is prone to trauma from occlusion and impaired oral hygiene maintenance. Orthodontic treatment is beneficial for those patients because of better alignment of dentition, easier oral hygiene performance and improved esthetics. Correction of mesial tipped periodontal compromised teeth demands extra anchorage control to improve efficiency of uprighting and prevent movement of related teeth. This article presents two cases of severe advanced periodontitis with progress of full mouth reconstruction. Oral examinations disclosed the patients have mesial tipping teeth and will receive orthodontic uprighting therapy. Due to lack of strong distal anchorage the mini-screws were installed as an anchorage for orthodontic treatment on the distal edentulous ridge. Clinical results showed the mesial tipped abutments were uprighted in months. Using mini-screws as an anchorage can provide an efficient orthodontic tooth movement which is beneficial in periodontal-prostheses reconstruction.
