Resorbable Dome Device and Guided Bone Regeneration: An Alternative Bony Defect Treatment Around Implants. A Case Series
Parma-Benfenati, Stefano / Roncati, Marisa / Galletti, Primo / Tinti, Carlo
This case series presents the use of a resorbable "dome device" made of a slow, long-lasting resorbable suturing material to support the barrier creating and maintaining a secluded space to promote bone regeneration. Acellular dermal matrix or cross-linked resorbable collagen membrane, as barriers, combined with mineralized freeze-dried bone allograft, with simultaneous implant placement, were utilized in reconstructing non-space-making defects. Eight implants in six healthy patients were treated with a combination of these resorbable regenerative materials. Only one of seven was treated with a nonsubmerged approach. All sites remained completely covered and no implant exposure occurred during healing. At the 9- to 24-month reentry surgeries, the clinical bone density was equivalent to that of the native bone and the mean number of final exposed threads was 0.5. The mean buccal bone thickness achieved was 3.12 mm, with a mean total coverage of exposed threads in approximately 87.5% of the cases.
