NCT06990360
Five stryofoam mandibles were included in this study to assess the accuracy of using computer guided surgical stent in placement of dental implants. The mandibles were CBCT scanned and imported to 3diagnosys software to implant planning. 8 implants were placed in each mandible virtually, 4 anterior implants and 4 posterior implants were placed. The plan was exported as STL file to be imported to the CAD software for designing of the stent. The surgical stent is printed using Micro DGP printer and invision tec e-shell 600 clear resin was used. Stainless steel sleeves were placed in the surgical guide then placed in ethanol 99% to remove the excess monomer. The stent in placed over the mandible and sequential drilling was done until the desired osteotomies width was approached followed by the placement of the implants. Post-operative CBCT was done for the mandible including the implants to assess the accuracy, angulation and position of the placed implants
NCT06588140
Twenty completely edentulous patients with old, removable dentures with ill-fitting maxillary dentures, proper vertical dimension, and proper occlusion will be recruited for this trial. They will be rehabilitated with duplicated complete dentures manufactured by conventional and two different 3D-printed CAD-CAM Complete Removable Dentures techniques. Outcomes will be evaluated, including denture retention, which will be evaluated using a digital force gauge, and occlusal force distribution by using a t-scan.
NCT04006782
The objective of this study is to evaluate the survival of narrow dental implants (≤ 3,5 mm) in multiple fixed prostheses in comparison with standard diameter dental implants (≥ 3,75 mm) after 5 years of follow-up. The hypothesis of the study is that narrow dental implants under the evaluated conditions, have the same survival rate and clinical performance than the standard diameter implants.
NCT06395818
Each patient will receive 2 prefabricated CAD-CAM allogeneic bone blocks sterilized with gamma rays with different rehydration methods. Side I: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using hyaluronic acid \* Side II: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using saline solution Both blocks are fixed with osteosynthesis screws, covered with non resorbable membranes\*\* The membranes will be removed after 6 months, dental implants will be placed and core biopsy will be collected from the site of the implant placement for histologic evaluation
NCT05458271
Recent data suggested that an adequate volume of Keratinized Tissue (KT) around dental implant is a key factor to obtain aesthetic outcomes and to support easy long-term maintenance. The aim of this RCT is to test the volume-stable collagen matrix (VCMX) vs the Connective Tissue Graft (CTG) for peri-implant soft tissue augmentation during implant uncovering.
NCT06527378
Artificial intelligence (AI) is revolutionizing the dentistry, offering new opportunities to improve the precision and efficiency of implantology. This study aims to evaluate the current evidence on the use of AI in implant planning assessment
NCT06620497
The aim of this study will be to evaluate the marginal bone loss and prosthetic complications of stress-free implant (SFI) and milled bars used to assist mandibular 4-implant overdentures after 3 years
NCT06576778
The aim of this study is assessing the effect of provisionalization with a glass fiber composite framework on patients' quality of life and bone height changes before the insertion of a definitive PEKKTON framework of screw-retained maxillary implant-supported prosthesis at a one-year follow-up period.
NCT05219305
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.
NCT06554041
The goal of this clinical trial is to learn how different materials used in dental implants affect the surrounding gum tissue in adults who need dental implants. The main questions it aims to answer are: How do different materials (titanium, PEEK, zirconia, and lithium disilicate) affect inflammation around dental implants? What changes occur in inflammation markers in the gum tissue after 3 and 6 months? Researchers will compare the different materials to see which one causes the least amount of inflammation. Participants will: Receive dental implants made from different materials. Have samples of fluid from around their implants collected for analysis at 3 and 6 months. Undergo regular dental check-ups to measure gum health, such as bleeding and pocket depth around the implants.
NCT06378112
Extraction socket preservation is defined as alveolar ridge preservation within the bone envelope remaining after tooth extraction, meanwhile ridge augmentation is defined as increasing the volume of alveolar ridge beyond the bony envelope at the time of tooth extraction. It is recommended to use in cases where extraction socket anatomy is intact. In contrast definition "extraction socket augmentation" defines alveolar ridge restoration when bony walls of the socket are partly or completely lost. In the case of severe loss (\> 50%) of the buccal bone plate, preservation of hard tissue with a prolonged healing time before implant placement has been suggested. The null hypothesis of this experimental work states that: (i) the two different bone graft materials gained the same amount of bone following horizontal ridge augmentation procedure; (i) the two different bone graft materials exhibit similar histological and histomorphometric results Therefore, the main purpose of the current study is to compare two different biomaterials using guided bone regeneration procedures in the ridge preservation/ augmentation (hard-tissue preservation).
NCT06182670
The present randomized controlled trial aims to assess the influence of a new prosthodontics device (Gingival Former Abutment -GFA) on peri-implant bone loss and soft tissue changes and health after subcrestal oral implant placement. The participants will be divided in two groups and receive either crestal implant placement and traditional healing abutment or subcrestal implant placement and GFA. Clinical and radiographic examination will be performed at implant placement surgery, prosthetic load, 6 and 12 months follow-up.
NCT06150755
It is a randomized control clinical trial in which maxillary and mandibular dentures will be constructed, two implants will be inserted in the inter foraminal region in the edentulous mandible and immediate loading will be done. We will be comparing peri-implant marginal bone loss of two immediately loaded implants retaining mandibular overdentures with ball attachment versus intra oral welding titanium bar. Patient satisfaction will be assessed using oral health related quality of life.
