Treatment of a mandibular cyst before implant placement: case report

The aim of this case study is to present a clinical approach to treatment of a mandibular intrabony cyst employing guided bone regeneration principles and protection of the mandibular nerve prior to implant placement. A treatment approach employing a combination of grafting materials and membranes was used to treat the cyst and protect the mandibular nerve prior to implant placement. Micro CT, as well as histology and histomorphometrics, was used to evaluate treatment outcomes. Histological inspection showed bone regeneration at the grafting site. Histomorphometric analysis of the biopsy core rendered a total bone percent area of 58.87% and 41.13% soft tissue. Out of the total bone percent area, 90.45% was revealed as vital bone and 9.55% was graft remnant. The grafted area is supporting an implant-supported prosthesis in full function.
