Abstract
Advances in dentistry, as well as the increased desire of patients to maintain their dentition, have led to treatment of teeth that once would have been removed. Mandibular first molars are the most commonly extracted teeth due to dental caries and periodontal disease. These teeth are the major standpoint for occlusion, and also have a wide pericemental area. Hence, any defect in the root either mesial or distal, extraction is the most common treatment planned. Under specific conditions, only the diseased part of the tooth can be extracted after an endodontic treatment. A modified fixed partial denture design is fabricated to splint the remaining portion of the tooth to adjacent teeth. This procedure though daunting can be easily achieved and maintained successfully.
Highlights
A terminal abutment molar with extensive decay may be unsuitable for restoration
Treatment by hemisection is indicated for failure of an abutment within a fixed prosthesis, provided a portion of the tooth can be retained to act as the abutment for the prosthesis
Other indications include vertical root fracture confined to a single root of a multirooted tooth or any severe destructive process that is confined to a single root, including caries, external root resorption, and trauma
Summary
A terminal abutment molar with extensive decay may be unsuitable for restoration In such cases, the treatment options are limited and may include a removable partial denture or a dental implant to replace the missing tooth [1]. This procedure is indicated if there is severe bone loss limited to one root or involvement of class III furcations that could produce a stable root after hemisection. Since hemisected teeth fail by root fractures, it is important to restore them adequately by an extracoronal restoration [4] It is indicated where one of the root of molar is unsalvageable due to caries, periodontitis, or iatrogenic mishaps [5]. It is a conservative option with acceptable prognosis [6]
