The Brånemark Zygomaticus implant was used in conjunction with premaxillary standard implants for the reconstruction of resorbed edentulous maxillae. A total of 44 zygomatic implants and 80 premaxillary implants were placed in 22 patients. All implants were stabilized at phase II surgery using a rigid bar. After soft tissues had healed, implant-supported fixed prostheses were fabricated. This a...

A survey was undertaken to analyze osseointegrated implants placed in irradiated maxillae and mandibles. It was found that nine centers in Japan and two centers in the United States had placed 228 implants in 44 patients. Of 228 implants, 59 were placed in the maxilla, 169 in the mandible. Three of 169 implants placed in irradiated mandibles were removed; 17 of 59 were removed from maxillae. On...

discussion this segmental ridge-split procedure with gradual bone expansion provides a quicker method wherein an atrophic ridge can be predictably expanded and eliminating the need for a second surgical site. this technique also shows that immediate implantation in split ridge of mandible can be performed. introduction narrow alveolar ridges especially in posterior mandibular remains a serious ...

peri-implantitis is one of the most common reasons for implant failure. decontamination of infected implant surfaces can be achieved effectively by laser irradiation; although the associated thermal rise may cause irreversible bone damage and lead to implant loss. temperature increments of over 10ºc during laser application may suffice for irreversible bone damage.the purpose of this study was ...

Background: Receptor activator of nuclear factor kappa B ligand (RANKL) is one of the key cytokines in the induction of osteoclastogenesis both in vitro and in vivo.Several reports indicated the presence of sRANKL in gingival crevicular fluid of patients with periodontal diseases. Objective: To determine the presence of RANKL in peri-implant crevicular fluid samples of implants with peri-implan...
