Horizontal maxillary ridge augmentation with ridge split procedure and simultaneous implant placement: A case report

Treatment of edentulous maxillary anterior region with horizontal ridge atrophy presents a clinical situation in which the placement of endosseous implants might be complex or sometimes impossible without a ridge augmentation procedure. This case report presents management of horizontally deficient maxillary anterior ridge with ridge split procedure using piezotome and simultaneous implant placement. In contrast to other ridge augmentation techniques, ridge splitting allows for immediate implant placement following surgery reducing the overall treatment time and eradicates the possible morbidity from a second surgical site.

Piezoelectric driven mandibular ridge split technique with immediate implant placement: A case report

Narrow dentoalveolar ridges pose a major challenge for the successful placement of endosseous implants. This case report focuses on a Piezoelectric driven mandibular Ridge Split technique without vertical osteotomy for an immediate implant placement in a narrow alveolar ridge measuring 3.0mm. Following anaesthesia, a mucoperiosteal flap was elevated after giving a mid-crestal incision distal to 35 along the entire edentulous ridge. Then, with the help of a micro-saw and horizontal spreaders, an osteotomy site of required diameter was achieved. Finally twist drills were used and implants were placed in the expanded site. Clinically, healing was uneventful with no step defect in the expanded buccal bone and the final occlusion obtained was satisfactory. The Piezo-electric driven Ridge Split technique promises to be a minimally invasive option for horizontal augmentation of narrow alveolar ridges- predictability within a short interval of time and with minimal risk of fracture.

Evaluation of the Split-crest Technique with SimultaneousImplant Placement in Atrophic Edentulous Maxillary and Mandibular Bone: A 5-Year Follow-up Study

Aim: To evaluate the behavior of the alveolar ridge split technique in a series of surgical cases. Materials and Methods: One hundred and fifty implants were included in this study for a total of 60 patients. The surgeries consisted of a mid-crestal incision and subsequent bone management with a piezoelectric system. The implants were placed after the alveolar bone was expanded by about 3mm and present bony defects were filled by a mixture of 50% autogenous bone and a xenograft (Bio-Oss®). Bone fracture of the buccal alveolar plate occurred in 8 cases, and those were stabilized with osteosynthesis screws. Implants were simultaneously placed in 140 cases, out of them 4 failures occurred due to membrane exposition. Results: The osseointegration success was estimated to be 97.5%. Conclusion: This study concluded that the bone splitting/expansion seem to be a reliable, predictable, relatively noninvasive technique with limited intraoperative complications. Clinical significance: The study revealed that the alveolar ridge split can be used as an effective technique for atrophic edentulous maxillary and mandibular bone
