ABSTRACT
Root resective periodontal therapy is a procedure used to retain teeth needed for restorative abutments or occlusal support. Contraindications of root resective therapy include fused roots and inadequate bony support around remaining roots. When these situations exist, extraction is necessary. But in the appropriate cases, a patient with a periodontal condition resulting in alveolar bone loss in the furcation region is amenable to treatment with a predictable result using a combination of resective periodontal surgical therapy and subsequent timely prosthetic rehabilitation.

When a root and the overlying anatomic crown are removed as a unit, this procedure is referred to as a hemisection. Hemisection of a maxillary or mandibular molar is often a means of retaining teeth needed for restorative abutments or occlusal support. This treatment can yield predictable results using proper diagnostic, endodontic, surgical, and prosthetic techniques.

The ridge expansion technique using tapered osteotomes can be used anywhere in the maxilla when a change in external ridge morphology would be advantageous for both aesthetics and/or proper dental implant placement. Usually subsequent to tooth loss, the maxilla is generally somewhat undercut in form. This ridge expansion technique can be used to reduce the undercut by bulging out the base of the facial/buccal plate. This would recreate the illusion of root prominences (Figure 12) or permit implant fixtures to be inserted in a more upright position. The tapered osteotomes can therefore predictably be used to expand the buccal bone to simulate the presence of a root prominence for optimal aesthetics for placement of a fixed partial denture prosthesis (Figure 13).
