Treatment of intrabony defects using guided tissue regeneration and autogenous spongiosa alone or combined with hydroxyapatite/beta-tricalcium phosph…
2007
The aim of this case-control study was to investigate the clinical regeneration of deep intrabony defects using guided tissue regeneration (GTR) with autogenous spongiosa (ASB) alone or using GTR with a mixture of ASB with a bovine-derived xenograft (BDX) or a synthetic composite bone substitute (hydroxyapatite/beta-tricalcium phosphate [HA/beta-TCP]).Sixty-four patients with a total of 93 intrabony defects of 2- or 3-wall morphology and an intrabony component (IC)or=4 mm participated in this study. Defects were treated with a bioabsorbable membrane and ASB alone or ASB mixed with HA/beta-TCP or BDX. Clinical parameters measured at baseline and 12 months after surgery included IC, bleeding …
Maintenance of Class III Trifurcated Molars Versus Implant Placement in Regenerated Extraction Sockets: Long-Term Results of 2 Cases
2011
Studies to date have reached differing conclusions regarding the long-term prognosis of teeth with class III furcation involvement. Replacement of such teeth with implants could be an alternative. This report compares the treatment outcomes of 2 cases with similar disease progression: 1 treated by implant therapy and 1 maintained with nonsurgical periodontal treatment. Two patients with advanced chronic periodontitis and class III furcation involvement of all molars were treated. Case 1 received a conservative periodontal and antibiotic treatment, followed by 15 years of maintenance. In case 2, the molars were extracted and replaced with implants, and the implants were observed for 7 years.…
