Filter by:The bone grafting materials currently used in dentistry are autografts, allografts, xenografts, and alloplastic grafts. Among these different types of bone graft materials, autografts are considered to have the most predictable results due to their properties of osteogenesis, osteoinduction, and osteoconduction. However, bone autografts are rarely used due to the high morbidity associated with harvesting the bone graft from the patient with a second surgical site. Because of the increased risk to the patient with autogenous bone grafts, the current standard of care is an allograft, which is a bone graft harvested from cadaver sources such as Freeze-Dried Bone Allograft (FDBA). While allografts can only possess the qualities of osteoinduction and osteoconduction, they also have dramatically less morbidity due to the lack of a second surgical site. Our null hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) do not show positive changes in implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA Our alternative hypothesis states that: Experimental groups (mineralized, and partially demineralized dentin grafts) show similar or better results in terms of implant stability, survival, failure rate, probing pocket depth, and interproximal crestal bone level changes when compared to FDBA.
Comparison of Piezoelectric split-crest technique versus expansion using Hand Driven Ridge Expanders in treatment of Maxillary Narrow Ridges
The purpose of this study is to evaluate the soft tissue clinical results in patients that received, or not, a soft tissue augmentation around dental implant inserted immediately after the extraction.
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.
Ridge deformities can complicate prosthetic rehabilitation, especially in situations where optimal esthetic outcomes are desired. Simpler, less invasive and predictable treatments are needed in order to obtain soft tissue augmentation at edentulous ridges. Autogenous subepithelial connective tissue graft (SCTG) has always been regarded as the treatment of choice, but heterologous volume stable collagen matrix (VCMX) is emerging as a reliable alternative. The principal aim of the present RCT will be to compare the volumetric buccal soft tissue changes at edentulous areas after augmentation procedure using VCMX or SCTG. Parameters related to periodontal health at adjacent teeth and patient reported outcomes (PROMs) will be also assessed as secondary outcomes. Proving the non- inferiority of VCMX compared to SCTG would provide the specialists and general clinicians with an easier, less invasive and better tolerated technique for soft tissue augmentation at edentulous ridges and for improving aesthetic and cleansability of the prosthetic rehabilitation.
The purpose of the study is to compare soft tissue volume changes in terms of volume gain and stability around dental implants and PROMS in cases where a sub-epithelial connective tissue graft (SCTG) from the palate, Porcine collagen matrix (CM) or Porcine Acellular dermal matrix (PADM) is used after 3 and 15 months after implant placement.
Dental implant supported screwed prosthetic rehabilitations are associated to several advantages, as a minimal occlusal spaced and easier hygiene and maintenance. In this sense, screwed rehabilitations have been associated with lower frequency of biological and technical complications. Nevertheless, the screwing process results in the formation of a prosthetic chimney that requieres an appropriate sealing protocol. This protocol needs to include a material for the protection of the screw head. Nowadays, there is a lack of materials for this intended use with marketing authorisation. Several materials have been tested in the bibliography including PTFE, although there are not high quality studies. In this context, this clinical investigation aims to evaluate the efficacy and safety os a PTFE-based product (MAFILL) for the sealing of prosthetic chimneys and the protection of the screw head.
comparing immediate functionally loaded implants and immediate non functionally loaded implants in the posterior mandibular region on bases of bone density and bone loss evaluated by cone-beam computed tomography (CBCT).
- Patients were randomly divided in to two groups by using computerized software ; the first group received flat magnetic attachment design while the second group received dome magnetic attachment design.which the inclusion criteria is completely edentulous patient ,Age range from 40 to 70 year old ,skeletal class 1, both sexes - Implant stability will be measured for both groups using smart peg /osstell at the day of implant installation and after 2,4,8,12 weeks. - Patient satisfaction measure in 2 weak and after 12 weak by Denture satisfaction questionnaire
The aim of this randomised controlled trial (RCT) of split-mouth design was to compare patient preference and effectiveness of two different techniques for lifting the maxillary sinus: the crestal approach versus the lateral window approach.
