BACKGROUND: Horizontal atrophic ridges need a regenerative procedure for implant positioning and fixed rehabilitation. Cone Morse taper implants are characterized by the intimate fitting of the prosthetic interface with the absence of microgaps and micromovements of the interfaces. The aim of this case report was to evaluate the clinical outcome of Cone Morse implant design in split crest augmentation treatment. CASE REPORT: A female patient with partial edentulism of atrophic posterior maxilla was treated for split crest procedure and implant-supported rehabilitation. A full-thickness flap was elevated, and horizontal and vertical osteotomic lines were produced with piezoelectric device. A total of 4 Cone Morse Taper implants (Universal III, Implacil de Bortoli, Brasil) were positioned and the site was grafted with bone substitute and covered by a heterologous membrane. CONCLUSIONS: A complete healing of the surgical site was evident at the follow-up with no evidence of bone resorption. No radiolucency or inflammatory aspects of the treated site were evident in the radiographic control. Simultaneous Cone Morse implants positioning with split crest technique seems to be a promising treatment for posterior maxillary rehabilitation of atrophic edentulous ridges.

PURPOSE: An adequate bone volume for complete circumferential coverage of the implants is very important for obtaining a long-term success of oral implants. To avoid these problems various membranes and biomaterials were used, but soft tissue pressure could cause a membrane collapse toward the defect. The present work describes a ridge augmentation with titanium mesh shaped by adapting it to a bone defect in aesthetic areas. MATERIALS AND METHODS: Three patients with alveolar crest defects received three implants (Bone System, Milano, Italy) and the defects were filled with bone chips. The defects were covered with a titanium micromesh above which was positioned a resorbable membrane (Biogide, Geistlich, Wohlhusen, Switzerland). RESULTS: At the re-entry procedure the titanium micromesh appeared to be surrounded by a dense connective tissue with no clinical signs of inflammation. Clinically in all patients, no residual bone defects were observed, and a significant increase of the alveolar width or height was found. CONCLUSIONS: In conclusion the clinical results of the present study show that most certainly the space for the bone regeneration is one of the most critical factors in the success of the regenerative techniques.
