Tapered, Sand-Blasted, Large-Grit, and Acid-Etched Surfaced Internal Dental Implant in the Diverse Pathologic Jaw

Abstract

Purpose: The treatment of pathologic lesions in jaws either through conservative or radical approaches, frequently leads to a loss of teeth. As a result, patients will experience diminished masticatory and phonetic function as well as esthetic deficits. In this manuscript, we report multiple cases of successful implant rehabilitation after the conservative treatment of pathologic lesions in jaws utilizing allogeneic bone grafts and the installation of implant fixtures. Materials and Methods: In this study, we examined 8 patients with 8 different kinds of pathologic lesions in their jaws, who were treated with a conservative approach and rehabilitated with bone grafts and implant installations using internal dental implant type with tapered, sand-blasted, large-grit, acid-etched surfaces. Marginal bone loss was analyzed through radiograms, and the implant survival rates and graft outcome evaluations were recorded. Results: No significant difference was found in the mean marginal bone loss throughout the follow-up period. The survival rate of the implant and the success rate of graft were recorded as 100%. Conclusions: The results of this study suggest that conservative surgical management for pathologic lesions based on the understanding of the pathologies can be helpful for successful oral rehabilitation. In bone grafting, it is necessary to determine an appropriate timing and method considering the risk of recurrence and the vascularity of the recipient site. For subsequent implant placement, selecting an implant system suitable for the site of placement and placing it within 3 to 6 months after bone grafting can help the long-term maintenance of the grafted bone and dental implant.
