Abstract

|
|
Intrabony defects are bony defects whose infrabony component affects primarily one tooth. Several surgical approaches are performed for periodontal regeneration of intrabony defects including new bone, cementum, and periodontal ligament. Clinical improvement and histologic evidence of regeneration therapies have been reported; however, limitations in the predictability and effectiveness have also been also reported. Guided tissue regeneration and application of bone replacement grafts, enamel matrix derivative and recombinant human platelet-derived growth factor-BB are reportedly efficacious in regenerating intrabony defects. Defects with a depth >3 mm and a radiographic defect angle <25 degrees were reported to be most appropriate to regenerative procedures. Factors negatively affecting regeneration included smoking and excessive tooth mobility. Proper case selection, patient proficiency in good oral hygiene, and regular supportive treatment are required to maintain long-term results. Regenerative procedures including guided tissue regeneration with bone graft and application of EMD were performed in presented cases. Clinical and radiologic improvements were shown without any complications.
