  • Two patients with sufficient vertical bone height but insufficient bone width in the anterior mandibular edentulous area, less than 6mm in the buccolingual aspect, for implant placement were chosen for treatment with a ridge splitting procedure. The surgical technique involving greenstick fracture is described. This ridge splitting procedure could be simple placement of implants into ideal restorable positions in severely atrophic, knife-edged ridges and predictable for narrow edentulous alveolar ridge augmentation associated with implant placement. We experienced two cases to place implant with insufficient bone width in the anterior mandibular edentulous area for overdenture be ridge splitting technique. Thus, we will report two cases and review of the literature.

  • Various techniques have been developed, and the development of piezo electric devices have made it possible to widen the alveolar ridge even if the residual bone is dense or if there is a lack of cancellous bone between the cortical bones. In the operation of the mandibular posterior area, the flap is easily accessible to the ramus bone, from which high quality autogenous bone can be obtained, compared to other parts. A small autologous bone block can be used with particulated bone graft material using one screw for bone regeneration instead of a large autologous bone with two screws. The tapered implant design can minimize buccal bone fracture, even in severely atrophic mandibular areas. We report a case of 4 years following implant placement with ridge splitting and small autogenous bone graft in severly atrophic mandible. This report demonstrates a case of functional and aesthetic restoration in a patient through a collaboration.

  • The aim of this study was to evaluate the clinical applicability of a ridge splitting technique for reconstruction of narrowed edentulous alveolar ridges for dental implantation. 41 patients with 47 edentulous areas were included in this study. After corticotomy of a rectangular buccal segment and about 3-4 weeks healing period, the alveolar ridge was splitted, implant was placed. The initial ridge width varied between 2.5 and 7.0mm, average was 3.99mm. 68 dental implants were placed, and the gap between the implants and the bone is filled with various bone graft material, or none. All splitted sites showed sufficient bone volume for insertion of the implants at the moment of implantation. Over 1 year of follow-up period, five implants(7.3%) had mobility in two patients, among them, 2 implants(2.9%) sustained infection and removed. And any other complications were not noted. Our conclussion is that ridge splitting of the narrow edentulous area is a reliable and safe procedure in horizontally deficient ridges.
