Rehabilitation of a severely resorbed mandibular posterior ridge with implants poses a challenge to the clinician. Several techniques to address this challenge have been described in the literature. This case report describes the successful vertical and horizontal bone augmentation of a site of a previous implant failure with severe vertical and horizontal ridge deficiencies using tenting screws, cortico-cancellous particulate bone allograft, and a resorbable collagen membrane. A bone core was obtained at the time of implant placement, 8 months postoperatively, and histological findings showed the highest concentration of lamellar bone at the apical third; a 50-50% graft and lamellar bone proportion in the middle third; and a higher concentration of bone allograft at the coronal third of the bone core. Successful implant placement was achieved at the site. This case report demonstrates the effective use of tenting screws for vertical and horizontal bone augmentation and consequent implant placement in a severely resorbed ridge in the posterior mandible. |
