Filter by:The objective of the research project will be to compare immediate and early unitary implants for the rehabilitation of missing teeth in the upper aesthetic region. A randomized controlled trial will be conducted in parallel with 120 individuals (60 per group) who are above 18 years of age, periodontally healthy, and who need to perform only one unit implant in the upper aesthetic region between the second premolars. In the immediate implant group, the tooth will be extracted in a minimally traumatic manner and the implant will be installed immediately after the fresh alveolus. Bovine bone replacement will be inserted into the gap between implant and vestibular wall of the alveolus, and an immediate temporary will be installed immediately. The provisional will be maintained for 3 months when the definitive crown will be made. In the early implant group, the tooth will be extracted, and after 2 months the implant will be installed with the use of bovine bone substitute to restore the buccal bone contour. The implant will be submerged, and 3 months of osseointegration will be performed reopening and final crown making. In both groups, the individuals will be followed for 1 year after the installation of the definitive crown. The outcomes evaluated will be patient satisfaction (main outcome), gingival phenotype, visible plaque, depth of probing, submucosal bleeding, proximal radiographic bone level, tomographic vestibular bone volume, perimplant clinical aesthetic indexes (Esthetic Pink Score and Papillary Index), evaluation three-dimensional tissue from intra-oral scanning and 3D printing, implant-related quality of life, and early and late implantation failures. Linear and logistic models of generalized estimating equations that take into account the longitudinal character of the study will be used for data analysis.
A study by Allied Health Professionals to explore the experience of patients undergoing tooth extraction at Leeds Dental Institute in relation to antibiotic medication, dental anxiety and oral health practices
Clinical trial to evaluate the success rate of autotransplantation of teeth with advanced or completed root growth with intraoperative extracorporeal root tip resection in 20 patients.
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.
Tooth loss impact on daily living, mood and self-perceived well-being. However, psychological impact of teeth loss has not been evaluated. Present study aims to evaluate the psychological conditions of patients pending complete tooth extraction before and shortly after tooth loss using Hospital Anxiety and Depression scale (HAD) and Geriatric Oral Health Assessment Index (GOHAI).
A prospective RCT of intact extractions with delayed implant placement comparing extraction socket management effectiveness and office economics of two collagen matrices. Soft tissue wound healing will be assessed out to 4-months post-operative, when implants will be placed.
This study evaluates the success rate, as the biological and prosthesis complications, of posterior single-unit implants immediately loaded with a chair side Computer-Aided Design and Manufacturing (CAD-CAM) composite crown, after a follow-up period of 6 months,1,2,3,4 and 5 years. Complementary ex vivo analyses will be performed to evaluate the wear of restorations. The time and cost benefit of the presented digital workflow, as patient centered outcomes will also be evaluated.
The evaluation of the bone, using several techniques and on several aspects will be the purpose to study the possible impact of the kidney transplant (and, extensively, the pre-transplant dialysis, the organ replacement and the immunosuppressive therapy) could have on the bone metabolism and on the density of the bone where the implants are placed. The assessment on the bone density only in a retrospectively selected population that underwent the same surgical procedure will help the comparison of the data to get a satisfactory conclusion. The evaluation of other clinical and instrumental parameters in the test group makes the kidney-transplant patients bone quality clear, and will consequently demonstrate if implants are a feasible therapy for these patients.
Ultrasound activated pins have been used for the promotion of bone healing in combination with biodegradable membranes during bone grafting procedures. In the jaws, these pins have been successfully tested for both maxillary and mandibular ridge augmentaton. However, the usefulness of these pins in maxillary sinus lift procedures has not been tested. This study aims to use a bilateral split mouth design to compare the bone formation, healing and post-operative complications after the use of ultrasonic guided pins in a lateral window maxillary sinus augmentation procedure in comparison to lateral window maxillary sinus augmentation procedure procedure performed without the use of these pins.
