Periodontal regeneration of intrabony defects Using Resorbable Membranes: Determinants of the Healing Response. An Observational Clinical Study

Cortellini/Bowers


PMID: 8593979
DOI: 10.11607/prd.00.0118

A task force of periodontists established clincal and histologic outcomes (goals) for the treatment of intrabony defects and researched the literature for techniques that would most predictability achieve these goals. The group also identified factors that could influence predictability. The treatment outcomes selected by the task force included regeneraton of a true attachment apparatus; gain in bone and probing attachment levels; reduction in probing pocket depth; minimal gingival recession; increased patient comfort; esthetic appearance and state of wellness; and maintenance of health; comfort; and function over time. Based on evidence it was concluded that guided tissue regeneration, guided tissue regeneration combined with the use of decalcified freeze dried bone allografts, and freeze-dried allografts alone are the most predictable regenerative procedures for achieving selected treatment outcomes. Various factors, such as patient characteristics, the morphology of the defect, and the surgical technique can influence the healing response of intrabony defects. Patient factors, such as plaque control, compliance, and cigarette smoking, can directly affect predictability of periodontal regeneration. Defect selection is critical, and deep and narrow defects are the most predictable response to regenerative procedures. The number of remaining bony walls is important in grafting procedures, but their influence is questionable in guided tissue regeneration. Various technical procedures, such as flap design, defect debridement, and wound protection , may influence the predictability of regeneration.
