PURPOSE To compare the efficacy and complications of 2 different techniques for vertical bone augmentation at implant placement: particulated autogenous bone grafts covered either by resorbable collagen barriers supported by osteosynthesis plates (test) or by nonresorbable titanium-reinforced e-polytetrafluoroethylene (e-PTFE) barrier (control). MATERIALS(More)
The aim of the present review is to evaluate the English language literature regarding factors associated with the loss of oral implants. An evidence-based format in conjunction, when possible, with a meta-analytic approach is used. The review identifies the following factors to be associated with biological failures of oral implants: medical status of the(More)
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.(More)
BACKGROUND To minimize the risk of implant failure, osseointegrated oral implants are conventionally kept load-free during the healing period. During healing removable prostheses are used, however many patients find these temporary prostheses rather uncomfortable and it would be beneficial if the healing period could be shortened without jeopardizing(More)
BACKGROUND Insufficient bone volume is a common problem encountered in the rehabilitation of the edentulous posterior maxillae with implant-supported prostheses. Bone volume is limited by the presence of the maxillary sinus together with loss of alveolar bone height. Sinus lift procedures increase bone volume by augmenting the sinus cavity with autogenous(More)
BACKGROUND dental implants require sufficient bone to be adequately stabilised. For some patients implant treatment would not be an option without horizontal or vertical bone augmentation. A variety of materials and surgical techniques are available for bone augmentation. OBJECTIVES to test whether and when augmentation procedures are necessary and which(More)
BACKGROUND Periodontitis is a chronic infective disease of the gums caused by bacteria present in dental plaque. This condition induces the breakdown of the tooth supporting apparatus until teeth are lost. Surgery may be indicated to arrest disease progression and regenerate lost tissues. Several surgical techniques have been developed to regenerate(More)
UNLABELLED This review is based on a Cochrane systematic review entitled ‘Interventions for replacing missing teeth: dental implants in fresh extraction sockets (immediate, immediate-delayed and delayed implants)' published in The Cochrane Library (see http://www.cochrane.org/ for information). Cochrane systematic reviews are regularly updated to include(More)
PURPOSE Pelvic lymphadenectomy is frequently performed simultaneously with radical prostatectomy to determine lymph node status and the most frequently recorded postoperative complication is the development of a symptomatic lymphocele. This study evaluated TachoSil as an adjunct treatment in preventing lymphoceles after extraperitoneal pelvic(More)
Towards a systems toxicology-based risk assessment, we investigated molecular perturbations accompanying histopathological changes in a 28-day rat inhalation study combining transcriptomics with classical histopathology. We demonstrated reduced biological activity of a prototypic modified risk tobacco product (pMRTP) compared with the reference research(More)
