PURPOSE The purpose of this article was to evaluate the suitability of deep-frozen allograft for ridge augmentation procedures in severely atrophic maxillae and to evaluate the clinical success of dental implants inserted after grafting and before prosthetic rehabilitation. PATIENTS AND METHODS This study included 13 patients (3 men and 10 women) aged 36 to 65 years. All the patients selected...

AIM The zygomatic implant represents a non-grafting alternative for the oral rehabilitation of patients with extreme resorption of the maxilla. Nevertheless, there are few studies concerning their long-term prognosis. The purpose of this retrospective study was to evaluate the prosthetic rehabilitation success rate and the survival rates of machined surface zygomatic implants and conventional i...

BACKGROUND We derived mesenchymal stem cells (MSCs) from rat induced pluripotent stem cells (iPSCs) and transduced them with tumor necrosis factor alpha-stimulated gene-6 (TSG-6), to test whether TSG-6 overexpression would boost the therapeutic effects of iPSC-derived MSCs in experimental periodontitis. METHODS A total of 30 female Sprague-Dawley (SD) rats were randomly divided into four grou...

Purpose: To evaluate success rates and complications of implants placed with a flapless technique and immediately loaded in fully edentulous maxillae. Materials and Methods: Implants were placed in fully edentulous maxillae with a minimum insertion torque of 45 Ncm in underprepared sites to allow maximum stability at insertion using a flapless technique. Implants were immediately loaded. Outcom...

PURPOSE The purpose of this review was to highlight anatomic and biomechanical aspects of atrophic maxillae for implant possibilities. MATERIALS AND METHODS A MEDLINE electronic search of the years 1966 to 2009 was conducted with the keywords "atrophic,""resorbed,""edentulous," and "maxilla." RESULTS Twenty papers presented the following findings: (1) previous use of a removable prosthesis ...

PURPOSE The aim of this in vitro study was to assess the increase in the polygonal area of implant-retained prosthesis supports in edentulous maxillae with the use of tilted distal implants compared with the use of straight distal implants, using a variety of implant lengths. MATERIALS AND METHODS A total of 25 DICOM datasets of atrophic edentulous maxillae were provided. Bone augmentations i...

PURPOSE To provide a detailed presentation of computer-aided design/computer-assisted manufacture guidance in severely resorbed posterior maxillae to place implants in a very limited amount of bone, thus avoiding sinus grafting. MATERIALS AND METHODS Based on computerized tomography (CT) axial images, implant positions are planned using imaging software. A surgical template is fabricated and ...
