hydroxyapatite coated implant system was employed in this study. The patients were followed up for a median of 31.3 months (range, 4 to 103 months). Results: There were no failures in the cases of immediate implant placement. Findings and Conclusions: Originally, there was quite a difference in the shape between extraction socket and implant, so a certain consideration for implant site selection was needed to establish the initial fixation. Furthermore, meticulous cleaning, socket curettage/debridement was also necessary to remove infectious areas in extraction sockets of the compromised teeth. Finally, successful immediate implant placement would be promised when fulfilling certain inclusion criteria.http://dx.
Background:The rehabilitation of atrophic maxilla is a challenge for maxillofacial surgeons. Bone grafts, short implants zygomatic fixtures, has show good results, however on maxillary atrophy associated with hypoplasia, anterior cant lever can lead the rehabilitation to mechanical failure. Objective: The aim of this paper is to report the surgical protocol adopted to the correction of edentulous atrophic and hypoplastic maxilla. Methods: Three patients (one male and two females) with sagittal maxillary deficiency and class V (Cawwod and Howell) alveolar atrophy were selected. The patients were rehabilitated by means of Le Fort I osteotomy associated with zygomatic implants and immediate loading. All patients were able to receive fixed prosthesis 3 days after the surgery. Results: All implants remain healthy and in function. One prosthesis required maintenance on the abutments screws six months after surgery, after that no other problem occurred. Conclusion: Maxillary reposition by Le Fort I osteotomy associated with zygomatic implants can be an alternative to bone grafts on rehabilitation of atrophic maxilla with maxillomandibular disrepancy.http://dx.
