Filter by:The aim of this randomised controlled trial (RCT) of split-mouth design was to compare patient preference and effectiveness of two different techniques for lifting the maxillary sinus: the crestal approach versus the lateral window approach.
Currently, the most positive documented outcomes of periodontal regenerative therapy (PRT) in intrabony defects (IBDs) have been achieved with a combination of bone grafts ( BGs) and a regeneration material like membranes in guided tissue regeneration ( GTR) technique. Among the graft materials only autogenous bone grafts ( ABGs).and demineralized freeze-dried bone allografts (DFDBA), are considered regenerative materials. Polypeptide growth factors revealed a potential application in PRT periodontal because are the biological mediators during wound healing and regeneration and autologous platelet concentrates ( PC) constitute a safe and convenient approach to deliver them. Among PC, platelet-rich fibrin ( PRF) belongs to a group of second-generation blood autologous products prepared by peripheral blood centrifugation without any nonclotting agent, so to obtain a dense three-dimensional clot architecture that concentrates platelets, fibrin, leukocytes, cytokines, and sustain cellular migration. This clot is then compressed to obtain elastic and very strong membranes that can be used directly as membranes or as an agent, after chopping, alone or in combination with BGs. Several studies demonstrate that PRF is effective in promoting bone regeneration (BR) when used alone or in combination with BG during oral/ periodontal surgery. To date, there are very few published clinical controlled trials that compare the results of PRF + BGs to the outcomes of PRF / BG alone in the treatment of IBDs and no study about PRF + ABG in the same defects. Only one case report tested the use of PRF + ABG mixed with bovine hydroxyapatite in the treatment of insufficient alveolar ridge width in aesthetic area. The aim of the present study is to verify if the combined use of PRF + ABG in the management of IBDs may be a treatment modality clinically "not inferior" to that with Membrane + ABG.
The present study is a human, prospective, parallel, randomised controlled clinical trial conducted to explore the efficacy of injectable PRF around dental implants. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.
The purpose was to evaluate histomorphometrically the early healing at implants installed in sites prepared with either a sonic device or conventional drills.
The present study pretends to show the results of combining a modification of the Non-incised papillae surgical approach (NIPSA) attempting to improve the outcome in the treatment of teeth with advanced periodontal support loss.
The evaluation of the clinical data has demonstrated the conformity of the Resorbable Collagen Membrane (RCM), EZ CureTM, with the relevant essential requirements for its use in periodontal applications. The RCM is intended for Guided Tissue Regeneration (GTR) and Guided Bone Regeneration (GBR) procedures. It acts as a barrier against the migration of epithelial cells within the bone defect (performance) and thus complies with several surgical indications in the treatment of maxillofacial bone defects. It has been concluded that the risks associated with the use of this device are acceptable when weighted against the benefits to the patients. In order to improve the clinical data on the RCM, the manufacturer, Biomatlante, decided to assess that the performance and safety of the device are maintained until the reaching of its intended use. In this objective, the goal of this study will be to observe the following parameters: 1. Tissue regeneration (mucosa health on the site of implantation) 2. Safety (report of any adverse event) 3. Radiographic analysis of periodontal tissues
Recently, 4 mm long implants with a standard diameter have been used for the restoration of the posterior edentulous mandible with favorable results. However, randomized clinical trials reporting the results from full-arch fixed dental prosthesis that included 4 mm long implants placed in the posterior regions of the maxilla have not been published yet. The aim of the present study will be to compare the survival and success rates of 4 mm implants used as distal support of a maxillary full-arch fixed dental prosthesis with standard (10 mm) implants placed in association with a bilateral sinus floor augmentation procedure
Missing teeth usually result in functional and cosmetic deficits. Traditionally, they have been restored with dentures or fixed bridges. However, dental implants represent an excellent alternative which rely on the maintenance of a direct structural and functional connection between living bone and implant surface, which is termed osseointergration. When sufficient bone is available in maxilla, implant rehabilitation has shown high success rates of 84-92 %. Atrophy of the alveolar crest and pneumatization of the maxillary sinus limits the quality and quantity of residual bone, therefore complicating the placement of implants in the posterior maxillary area.
Tooth autotransplantation is a treatment option to replace tooth with imposible prognosis. In several cases the receipt site has a reduced bone dimension. This situation may be imposible the treatment with dental implants without bone reconstruction. Autotransplantation seem to improve the anatomic characteristic of the receipt site without any reconstruction approach. The aim of this study is to evaluate the bone dimension changes followed autotransplantation treatment.
The main aim of this prospective, randomized controlled clinical study is to: • To evaluate and compare the effect of a combined orthodontic -periodontal treatment protocol versus periodontal treatment alone on osseous and non -osseous parameters in periodontally compromised patients.
