Filter by:The present study is a human, prospective, randomised controlled clinical trial will be conducted to explore and compare the clinical, radiographic and histomorphometric outcome of autogenous demineralised dentin(DDM) versus bovine derived xenograft(DBM) for socket preservation procedure.
The rehabilitation of dentoalveolar defects and tooth loss has seen remarkable advancements over time. Extraction of tooth leads to reduction in physiologic dimension of bone and it is imperative to evaluate the site before implant placement. To overcome the loss of volume and to avoid complications, procedures to restore the resorbed alveolar bones prior to or during implant placement are usually performed. Lateral bone augmentation procedures with guided bone regeneration (GBR) are well documented in the literature with predictable results. It generally involves bone substitute xenograft and bioresorbable membrane combined with implant placement in single stage procedure or separately in two- stage procedure. As the search for better and improved materials continues, a porcine derived ribose cross-linked volumising collagen matrix (VCMX) based on GLYMATRIX® technology has been introduced which showed benefits over the conventional membranes in terms of simplified procedure, degradation, membrane exposure and healing. The collagen scaffold has been reportedly used as a core material for guided bone regeneration, when there is sufficient bone to place an implant but a horizontal defect is present in the crestal ridge. As part of augmentation VCMX is designed to expand and ossify during healing. The advantage of the material is that when placed in one or two layers, it may eliminate the use of bone substitute or connective tissue graft thus simplifying the augmentation procedure. In addition, adding a bone substitute is a valid option based on indication. In the quest of better material and simplified procedures, few authors have performed case studies based on application of VCMX for guided bone regeneration around dental implants and has shown promising results. However, there are no controlled clinical trials on application of VCMX for lateral ridge augmentation. Thus, the present study aims to assess the efficiency of VCMX compared to resorbable collagen membrane (RCM) and bone graft (BG) for lateral ridge augmentation around implants through a well designed, controlled clinical trial.
Autogenous bone graft has been considered the gold standard in Guided Bone Regeneration (GBR) technique used for bone augmentation. However, there are disadvantages associated with autograft use such as limited amount of available bone and increased morbidity for the patient at the sampling site. Several biomaterials have been used as a replacement of the autogenous bone. Viral-inactivated bone allograft powder is an alternative that has proven efficacy and tolerance. This study aims to assess the non-inferiority of viral-inactivated allogeneic bone paste compared to a viral-inactivated cortico-cancellous allogenic bone powder in achieving the ideal bone volume.
This randomised double blind, placebo-controlled study examined the effects of post-exercise consumption of whey protein (PRO) or carbohydrate (CHO) on performance recovery, muscle damage and inflammatory cytokine responses following a high intensity interval swim (HIIS) in 10-17-year old male and female swimmers.
The purpose of this randomized controlled trial is to compare clinical data and implant stability of immediately loaded TSIII Osstem implants with Sandblasted and Acid-etched (SA) surface versus implants with SA surface modified with pH buffering agent for the rehabilitation of single implant-supported crown.
This study evaluates implant survival and marginal bone resorption in patients receiving implant treatment with respect to demographic data and AB0 (groups) blood types.
Vertical bone height has always presented challenge for the clinicians especially in the anterior aesthetic zone. Therefore, this trial will attempt to compare whether better vertical bone height and implant placement technique can be achieved using simultaneous implant placement with the sandwich osteotomy, which is a time saving procedure performed in a single stage surgery; when compared to using fixation plates to support the segment followed by delayed implant placement.
Twenty patients referring to periodontics department of Boroujerd Azad university of dentistry after obtaining consent to participate in teh research project, which TEMPhas more TEMPthan 20 teeth, are over 18 years old and require socket preservation surgery to tooth extraction for teh periodontal problem, caries or Fractures were selected.
This study will be an open, prospective, split-mouth, randomised controlled clinical trial. A total of 14 patients searching for oral implant treatment and where a GBR procedure is indicated per implant treatment will be enrolled. All patients have to fulfill all of the inclusion criteria and none of the exclusion criteria. From all patients clinical photos will be taken. Two sites within a patient will be randomly allocated to the 'autologous bone chips and DBBM or 'DBBM particles alone' group. The study will be 1 year follow-up study comprising 9 visits
the aim of the present study was to evaluate the dimensional variation and osseointegration of mini-implants at augmented sinus with the antrostomy left unprotected or protected with a collagen membrane.
