Filter by:The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery.
The aims of this clinical study are: 1) to compare the accuracy of conventional versus digital impression techniques for implant impressions; 2) to assess the passive fit of the prosthesis constructed from the most accurate impression. Thirty edentulous patients who received 4 - 6 implant and indicated for implant-supported fixed prosthesis will be invited. Full-arch conventional and digital impressions will be made for each patient. Accuracy evaluation will be made and the prosthesis will be constructed from the most accurate impression. Passive fit of the zirconia implant-supported prostheses will be verified at the try-in stage clinically and radiographically.
This study is a prospective case series clinical study to examine the effectiveness of Ceramic dental implants manufactured by Swiss Dental Solutions (SDS). Participants with an indication from the dentist for teeth extraction and replacement are invited to participate in this study. Participating in this study will involve the use of dental implants manufactured by Swiss Dental Solutions (SDS zirconia dental implants), submission of the case data, including pre-operative information, intra-operative details, and post-operative follow-up data, to the study site and its collaborating partners. The SDS zirconia dental implants used in this research are FDA cleared devices that are available for dental treatments.
The goal of this clinical trial is to compare, the effect of letting the xenogeneic bone graft exposed to the oral environment or seal off the graft with a collagen matrix. Them main questions it aims to answer are: - The enhancement of soft tissue healing during the initial phases following immediate implant placement. - The secondary aim is to evaluate the dimensional alterations in hard tissues at immediately placed implants and different biomaterial protocol. It were selected patients with indication of flapless extraction in posterior teeth, which was placed immediate implant (n=28) and gap filling with deproteinized bovine bone mineral (Geistlich Bio-Oss®). In this study, participants were stratified into two randomized blocks, each corresponding to a distinct surgical technique: left exposed the graft to the oral environment or coverage with a collagen matrix (Geistlich Mucograft®). - Previously the extraction was performed the measurement of the keratinized gingiva, and after 04 months of implant placement. - The soft tissue healing was evaluated on days 02, 07, 30 days; by means of a blue-stained solution (methylene blue 0.05%) and standardized photograph. - In the same date from different healing times it was performed immunoenzymatic analysis of the levels of VEGF (vascular endothelial growth factor), IL-1β (interleukin-1β) and FGF2 (fibroblast growth factor 2). - It was also be performed cone beam computed tomography images quantifying the soft and hard tissues thickness of the facial and lingual bone wall. The clinical trial examiner was blinded during the study period.
This study is designed as a retrospective, single center study. Up to 15 participants who had a transcrestal sinus elevation and implant placement using autogenous bone supporting an OSSIX Volumax collagen xenograft scaffolding will be enrolled. The study will include data collection from medical records and data collected at a follow up visit between January 2019 and March 2023.
The study is prospective randomized clinical trial that aims to evaluate the adjunctive use of L-PRF in promoting the desired vascularization and bone fill in small and large defects following tooth extraction and report on the long-term implant and patient outcomes
The loss of a single tooth could negatively impact the physiologic occlusion because of the tipping of neighboring teeth and the super-eruption of the opposing teeth. In addition, it compromises the esthetic, especially when anterior teeth are missing, leading to psychological problems such as loss of confidence and avoidance of smiling in public with a defect in phonetics. Restoration of the missing tooth is achieved in many ways, including removable dental appliances, fixed dental prostheses and dental implants. Implant placement is classified into different protocols according to the time of placement in relation to the time of extraction. These different protocols are immediate implant placement (type 1) on the day of extraction; early implant placement (type 2) after 4-8 weeks with soft tissue healing; early implant placement (type 3) after 12-16 weeks with partial bone healing; and delayed dental implant placement (type 4) after complete bone healing at least 6 months after tooth extraction the Aim of the work: to evaluate facial bone changes after early implant placement protocols clinically and radiographically.
This study consists in a randomized controlled trial which objective is to assess the accuracy of a dynamic navigation system in zygomatic implant placement in partially or total edentulous patients in the upper jaw compared with the conventional freehand method.
The goal of this randomized clinical trial is to compare biting force and patient satisfaction in three groups. Patients in the control group number one will receive a CoCr removable partial denture, and in the other two groups, implants will be inserted to restore missed posterior teeth (second mandibular premolar and second mandibular molar) in the span area. After three months, implants will be loaded with three units of anatomical PFM-fixed partial dentures in group number two, while in group number three, implants will be loaded with three units of anatomical Zirconia-fixed partial dentures. Biting force will be measured bilaterally at the time of delivery of the removable partial denture and delivery of fixed partial dentures after two, four, and six months. Patient satisfaction will be assessed through a quality-of life questionnaire at the six-months recall appointment
The goal of this randomized controlled clinical trial is to compare implant stability between hybrid implants and fully rough implants in partially edentulous patients. The main question it aims to answer is: are hybrid implants able to achieve a sufficient level of secondary stability in comparison to fully etched implants? Participants will receive dental implants and the secondary stability will be measured using resonance frequency analysis (RFA) at the 2-month post-implant placement mark. Implants that do not attain adequate secondary stability will undergo re-evaluation at monthly intervals up to 6 months. Researchers will compare the test group (hybrid implants) or the control group (fully rough implants) to see if they present a comparable secondary stability.
