Filter by:Together with materials and type of retention, the stability of the implant abutment connection represents one of the key factor for the success rate of an implant supported restoration. The recent diffusion of high quality and easy to use CAD/CAM systems has contributed to market launch of a number of competing companies that offer the so called "clonical" or "compatible" restorative components. Although they are claimed to be identical, the original abutments are supposed to present maximum accuracy and consequently lower microleakage. The aim of the present randomized controlled trial will be to analyze the implant abutment junction stability comparing implant-supported crowns restored with original components and compatible non-original abutments. The hypothesis is that original components will present significantly better stability than non-original abutments.
Comparison of cronally advanced lingual flap to modified periosteal releasing incision (MPRI)
To overcome the disadvantage of complex morphology and availability of less favorable support to retention of graft and clot stabilization in 1-, 1-2-wall periodontal defects, it was hypothesized that placement of CPS putty having the property of being easily moldable and shaped along with decortication would provide better healing outcome as compared to decortication alone in 1-, 1-2-wall periodontal defects. Therefore with this rationale, the present study is carried out to evaluate the treatment outcomes of decortication with and without use of CPS putty in 1- wall, 1-2-wall periodontal defects.
To compare clinically and radiographically the efficacy of demineralized freeze-dried bone allograft with and without decortication in the treatment of periodontal intrabony defects assessed by gain in clinical attachment, reduction of pocket depth and radiographic bone fill.To evaluate clinically and radiographically the regenerative potential of demineralized freeze-dried bone graft (DFDBA) material in periodontal intrabony defects.To evaluate clinically and radiographically the regenerative potential of demineralized freeze-dried bone graft (DFDBA) when used in combination with decortication in periodontal intrabony defects.
In this study the buccal fat pad derived stem cells (BFPSCs) will be harvested from buccal fat pad tissue of patients receiving maxillary sinus augmentation. In the test group the patients receive a combination of platelet rich fibrin (PRF) and freeze dried bone allograft (FDBA) (SureOss, Hansbiomed, Korea) loaded with BFPSCs. The results will be evaluated by cone beam computed tomography (CBCT)and hematoxylin and eosin staining in 6 months.
In this study the buccal fat pad derived stem cells (BFPSCs) is harvested from buccal fat pad tissue of the patients receiving posterior mandible augmentation. In the test group the patients receive a combination of platelet rich fibrin (PRF) and freeze dried bone allograft (FDBA) (SureOss, Hansbiomed, Korea) loaded with BFPSCs. The control group receivesFDBA (without any cells)+PRF. In all the groups the combination are placed between the recipient site and the block graft obtained from lateral ramus. The results will be evaluated by cone beam computed tomography (CBCT)and hematoxylin and eosin staining in 6 months.
Crestal bone and soft tissue stability around implants is an important issue in implant dentistry. Initial vertical mucosal tissue thickness was shown to be one of the factors having impact on bone stability. However, there is lack of data in the literature regarding the relationship between mucosal thickness and marginal bone loss around implants. Berglundh and Lindhe in an animal study reported that thin mucosal tissue causes significantly more crestal bone resorption around implants. In addition, clinical research regarding the effects of tissue thickness on bone and soft tissue stability around implants is lacking. The aim of this clinical study is to evaluate the influence of mucosal tissue thickness on soft and hard tissue changes around implants.
