The purpose of this study was to investigate the quality of bone at grafted implant sites in the anterior maxilla. Grafting of these sites was necessary because of insufficient bone volume in a buccopalatinal direction (width at the top of the crest 1-3mm). Reconstruction was performed with chin bone (N=5), chin bone and a resorbable Bio-Gide GBR membrane (N=5) or Bio-Oss spongiosa granules in combination with a Bio-Gide GBR membrane (N=5). Biopsies were taken prior to implantation, i.e. 3 months after grafting with chin bone, and 6 months after grafting with Bio-Oss. Evaluation was done by assessing the histological and histomorphometric characteristics of full-length biopsies taken from the actual implant site. Both areas with non-vital bone and areas with apposition of bone and remodelling phenomena were observed in the chin bone group at the time of placement of the implants. Similar results were observed at implant sites reconstructed with a chin bone graft covered by a membrane. In the chin bone group without and with a GBR membrane, the mean total bone volume (TBV) was 55.2+/-6.8% and 57.7+/-11.5%, respectively; the marrow connective tissue volume (MCTV) was 44.8+/-6.8% and 42.3+/-11.5%, respectively. Remnants of the resorbable GBR membrane were not detected. In the Bio-Oss((R)) group, at implant placement some newly formed bone was observed in the connective tissue surrounding the Bio-Oss((R)) particles (mean TBV (newly formed bone) 17.6+/-14.5%), but most particles were surrounded by connective tissue. No convincing signs of remodelling were observed (mean remaining Bio-Oss volume 40.5+/-9.3%; mean MCTV 41.9+/-13.1%). No implants were lost during follow up (12 months). At the time of placement of the implants the grafting material (either chin bone or Bio-Oss is still not fully replaced by new vital bone. In case of Bio-Oss, most of the grafting material is even still present. Despite these differences, the 1-year clinical results were very good and comparable between the various grafting techniques applied.

“…Treatment of atrophic ridge especially in posterior mandibular is accompanied with great problem in achieving successful results with endosseous implants. Although different techniques exist for reconstruction of atrophic ridge, there are chances of surgical risk, postoperative morbidity and multiple surgeries (2,3). Various surgical widening techniques have been described, including lateral augmentation with (4,5) or without guided bone regeneration (GBR) (6), ridge expansion osteotomy (7,8), ridge splitting technique with (9,10) or without (11) interpositional grafting and horizontal distraction osteogenesis (12).…”

Introduction: Narrow alveolar ridges especially in posterior mandibular remains a serious challenge for successful placement of endosseous implants. Case Presentation: This case report addresses surgical procedures for widening the atrophic ridge by means of splitting the crest of an edentulous ridge as thin as 2.5 mm and gradual expansion in the posterior mandibular ridge, then simultaneous placement of dental implants within the split ridge. A significant increase was achieved in the bone dimension, which enabled the placement of endosseous dental implants successfully. 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.

“…Using the mandibular symphysis as a donor site offers ease of access, good bonequality for localized repair, a corticocancellous block graft morphology, low morbidity, and minimal graft resorption. A procedure for harvesting and placing an autogenous mandibular bone graft is presented; as are the advantages of using this location as a donor site compared with other locations [8].…”

Purpose: To systematically review clinical studies examining the survival and success rates of implants in horizontal ridge augmentation, either prior to or in conjunction with implant placement in the anterior maxilla. Materials and methods:A literature search was undertaken up to September 2012 including clinical studies in English with ≥ 10 consecutively treated patients and a mean follow-up of at least 12 months. Two reviewers screened the pertinent articles and extracted the data. Key words focused on the outcome parameters (implant success, implant survival, horizontal bone gain, and intra-and postoperative complications) in studies utilizing either a simultaneous approach (ridge augmentation performed at the time of implant placement) or a staged approach (ridge augmentation performed prior to implant placement) were analyzed.Results: A total of 10 studies met the inclusion criteria, Mean horizontal bone gain determined at reentry (implant placement) ranged from 3.4 to 5.0 mm. Intraoperative complications were not reported. Postsurgical complications included impaired sensibility in the soft tissues of the chin. The lower lip and teeth showed fewer disturbances. Conclusions:Staged and simultaneous augmentation procedures in the anterior maxilla are both associated with high implant success and survival rates.
