Active clinical trials for "Alveolar Bone Loss"

A deficient alveolar ridge segment in prepara¬tion for implant placement can be regenerated by several techniques. The type of graft material for each patient depends on many factors such as the anatomy, the morphology of the bone defect, type of prosthodontic rehabilitation and patient or clinician preferences. Bone graft material should have three properties that made it ideal: a) osteoconduction, it provides scaffolds for bone regeneration; b) osteoinduction, it promotes the recruitment of bone-forming cells and formation of bone and c) osteogenesis, induction of cells in the graft to promote regeneration of the bone. Despite of the development of different types of graft material, autogenous bone is still the gold standard for bone augmentation because it exhibits these three mentioned properties. Although it has many advantages, autologous bone has some disadvantages such as high resorption rate up to 50 %, limited source and donor site morbidity. Allografts, xenografts and alloplastic bone graft are materials that are used in everyday practice and over long period, but their disadvantages are numerous in comparison with autologous bone. Allografts can be carrier of some disease and show lack of osteoproliferation, while alloplasts and xenografts show only osteoconduction. According to these facts, it is obvious that there is a need for development an alternative graft material that will surpass these disadvantages.The reconstruction of deficient alveolar ridge defect by the lateral bone augmentation prior to the dental implant placement is predictable and commonly used method. Except animal studies, recent clinical studies showed that there is no difference in the osseointegration of titanium implants in deficient alveolar ridges reconstructed with autogenous cortical bone blocks or autogenous teeth.

The purpose of this prospective clinical trial is to investigate and identify factors associated with the failure of dental implants within the population rehabilitated with dental implants at the Folktandvården Specialistklinik in Malmö (Spårvägsgatan 12, 214 27, Malmö).

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.

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.

This study is intended to evaluate the efficiency of graftless maxillary sinus augmentation with concentrated growth factor (CGF) utilizing "dynamic implant valve approach" (DIVA) system.

comparison of alveolar bone resorbtion/ changes for a period of 12 month post loading of different designs and brands of oral implants. in this study, a comparison between straumann SLA-active implants to MIS Mistral and Mistral -X implants.

This study is meant to assess clinically the possible predictable clinical attachment gain regarding the use of vitamin C with platelet rich fibrin versus platelet rich fibrin alone in the treatment of 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.

The aim is to evaluate the value and efficiency of sticky bone in the augmentation of alveolar ridge deficiency when being used with or without xenogenic bone graft for esthetic implant placement.

The aim of this study is to evaluate the periodontal outcomes after applying antimicrobial photodynamic therapy with a novel photosensitizer as compared to LASER assisted scaling and root planing alone.
