Filter by:Aim of the current randomized clinical trial is to evaluate and compare the effectiveness of computer-guided ridge splitting approach assisted by artificial intelligence versus conventional approach combined with simultaneous implant Placement.
Customized bone blocks need CBCT and digital software to design the block needed to rehabilitate. Some advantages are reduced surgical time and better adaptation of the graft, leading to less complications. Objectives: The primary aim of this study is to determine the bone regeneration capacity through a histological study and the bone volumetric changes of allograft bone blocks in the posterior site of the mandible. The secondary outcome will be to assess the survival and success rate of dental implants placed in the allograft regenerated area. Materials and Methods: After studying the CBCT to regenerate the posterior sites of the mandible, the investigators will design CAD/CAM freeze- dried bone allograft to fit exactly on the defect morphology that the patients present. A full thickness flap will be released to have a correct access of the defects. The sterile blocks have to fit perfectly on the defect and fixed by screws. Covered with resorbable membranes fixed with pines and suture. 4 months later, 2nd CBCTwill be performed. During the implant surgery, a bone trephine will be removed and sent into a Laboratory to make a histological study of the bone block for histomorphometry. After 3 months, second-stage surgery and healing caps will be placed if needed. Impressions will be taken 2 weeks after to perform the final crowns.
In this experiment, after non-traumatic tooth extraction, the blank group underwent natural healing, and the control group underwent alveolar ridge preservation using Bio-Oss Collagen and the experimental group using Sticky Bone, to verify the application of Bio-Oss Collagen and Sticky Bone in alveolar ridge preservation
Many dentists, clinicians and researchers have conducted numerous trials, and put several materials and procedures under the test, in an attempt to preserve vertical and/or horizontal extraction sockets dimensions. The clinical consequences of post-extraction remodeling may affect the outcome of the ensuing therapies aimed at restoring the lost dentition, either by limiting the bone availability for ideal implant placement or by compromising the aesthetic result of the prosthetic restorations. In an attempt for ridge/socket preservation of a freshly extracted tooth socket/bed, this study aims to assess and compare between using autogenous tooth graft added with Hyaluronic acid, and the usage of the standardized autogenous tooth graft alone, regarding the potency, preservative feature, and quality of bone healing, density, and deposition. For a better restorative outcome using a delayed implant placement later on in the edentulous area.
Following tooth extraction, volumetric changes in the soft and hard tissues of the extraction site are expected to occur with considerable resorption of the alveolar bone in both the vertical and the horizontal dimensions. These changes may complicate surgical implant placement and may also compromise the outcome of the prosthetic reconstruction. Various treatment approaches have been introduced aiming to preserve the dimensions of the alveolar ridge at the extraction site and facilitate optimal implant placement. This prospective randomized controlled trial aims to determine the efficacy of alveolar ridge preservation utilizing two different socket seal approaches compared to spontaneous healing to stabilize the blood clot within the postextraction socket. Thirty-six subjects will be randomly allocated into one of the three treatment groups. Group-A: Extraction of the tooth and suturing of the extraction socket with resorbable suture PGA 5/0. Group-B: Extraction of the tooth and placement of a Free Gingival Graft stabilized with resorbable suture PGA 5/0. Group-C: Extraction of the tooth and placement of the Polylactic-Glycolic Acid membrane stabilized with resorbable suture PGA 5/0. After the initial examination for screening, subjects will be assessed at baseline-extraction day- and after 1, 2, and 6 weeks, and 3 months. The changes of the alveolar crest will be determined in height and width, in addition to volumetric changes in the soft tissues, and the width of keratinized tissues. The wound healing process will be visually assessed.
The primary aims of this study are to compare, after 4 months, the clinical and histologic results of a combination demineralized/mineralized putty allograft vs. synthetic calcium phosphosilicate (CPS) putty alloplast graft utilization in socket preservation procedures. A regenerative tissue matrix membrane will be used to cover each graft lying below the flap.
In this clinical study ridge splitting procedures are preformed using autogenous bone blocks. After a 3-month healing, at the time of dental implant placement bone core biopsy samples are harvested. The samples undergo micro-Ct and histomorphometric analysis.
This pilot multicentric randomized controlled clinical trial is aimed at evaluating the composition of the new-formed tissue into the dental socket after 6 months from tooth extraction and the application of a combination of xenograft bone granules and collagen membrane. Extraction sites will be either grafted with Dentsply Symbios Xenograft Granules and covered with Dentsply Symbios pre-hydrated Collagen Resorbable Membrane or grafted with Geistlich Bio-Oss Collagen and covered with Geistlich Bio-Gide membrane. Results will be compared to spontaneous socket healing.
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.
