Long-term prognosis following resectional and regenerative periodontal procedures.

The ultimate goal of both resective and regenerative periodontal procedures is the creation of soft- and hard-tissue architecture that is consistent with periodontal health. Osseous resective procedures predictably produce minimal clinical probing depth, but sacrifice periodontal support. An alternative method to treat anatomic defects not easily managed through resection is guided tissue regeneration (GTR). GTR provides clinicians with the opportunity to reverse the disease-related loss of periodontal attachment. However, at present, the outcomes of GTR procedures have not been shown to be predictable. Continued improvements in techniques and materials, and identification of patient-related factors significant to the success of the GTR procedures, should enhance the consistency of the clinical outcomes. An evidence-based approach to the use of both regenerative and resective therapies will enhance the clinical results achieved through these procedures.
