Restoration Of Amputated Tooth With Fixed Restoration: A Case Report, Sittidej Nincharoen, Sunphat Namano Jan 2003

Restoration Of Amputated Tooth With Fixed Restoration: A Case Report, Sittidej Nincharoen, Sunphat Namano

Chulalongkorn University Dental Journal

Restorative treatment planning is often confounded when periodontal attachment loss, caries or tooth fracture involves the furcation area of the multirooted molars. Although such involvement invariably diminishes the long-term prognosis of the affected teeth, extraction is not always a good option. Root resection, which removes the involved root plus its associated crown portion, is one of several treatment modalities that can be used in such cases. This paper reports a patient having a fixed bridge restoration by using a lower molar and a resected tooth of a lower molar as abutments. For this case, the semi-precious alloy is the metal …
