Filter by:To report the clinical and radiographic outcomes of implant-supported fixed dental prostheses with full-ceramic cantilever extensions (FDPCs) after a function time ≥ 12 months.
The aim of the study is to prospectively evaluate the survival of JJGC Cobalt-Chromium (CoCr) prosthetic abutments in single-unit implant-supported prostheses, to confirm the long-term safety and performance of the devices.
This study is part of the clinical evaluation of SEBBIN silicone gel-filled INTEGRITY implants, included in the technical file of the device. The aim of the study is to gather additional data about the safety and effectiveness of the device.
The objectives of this study are to evaluate the performance and safety of the Vantage Total Ankle System. This study will follow subjects for a period of up to 10 years post-surgery.
Data on valve performance following ViV-TAVR has usually been obtained with the use of Doppler-echocardiography. However, some reports have shown significant discordances in the evaluation of mean transvalvular gradient between echocardiography and catheterization, with an overestimation of the real gradient with echo (vs. cath) in most cases. Thus, the incidence of procedural-device failure may be lower than that reported in the ViV-TAVR literature,
In recent years, zirconia-based implant-supported bridge designs have begun to be used more and more as an alternative to metal ceramic bridges. Another new material that has been introduced in the clinic is the high translucent monolithic zirconia, which has only been investigated a few follow-up studies with short follow up duration. The aim being to evaluate the clinical outcome of implant-anchored posterior bridges, made from 1. high-translucent monolithic zirconia, 2. zirconia ceramic with porcelain and 3. metal ceramics. The hypothesis is that high-translucent monolithic zirconia has lower rate of complications since surface porcelain veneering is not required. A total of 60 research subjects will be included in the study. Patients in need of a permanent implant-supported bridge, located posterior of the canine in the upper or lower jaw will be asked for participation. Each subject will be treated according to standard treatment protocols with implants from Nobel Biocare, the Branemark implant system and then be randomly assigned to obtain one of the following three type of bridges. 20 research subjects will be included in each of the three study arms. The prosthetic treatment will be carried out according to standard clinic protocol. All research subjects will be evaluated after 1, 3, 5 years. X-rays and photos will be taken at the installation of the bridges and after 1 and 5 years of follow-up or more frequent, depending on individual indication of the patient and the associated standard clinical care protocol. Personal data, implant survival, marginal bone loss and biological and technical complications related to the implants will be recorded. Survival of the bridge, technical and biological complication related to the bridge will also be recorded
The finger and fingertip are the most frequently amputated body parts, due to work-related incidents. Yet because of space, weight and cost constraints, prosthetic fingers and fingertips are heavy and bulky with limited active motion and sensation. Most are basic variations on the hook and claw. Lower limb prostheses have become extremely technologically advanced in their design and materials, and upper limbs lag behind in all of these areas. This is due to the complexity of the anatomy and function of the upper limb compared to the lower. There are no commercially available prostheses that offers direct sensory feedback and as such, rely on visual feedback from the wearer. The original PROLIMB study (PROLIMB I) used a Leap Motion Controller (LMC) to investigate the type of grasp adaptation that have been undertaken by patients during the rehabilitation process following amputation and compared this to similar data from healthy volunteers. PROLIMB I also looked at refining the tactile feedback system by investigating the sensation felt on amputation sites in order to feed this information into the haptic feedback system. The vision of the PROLIMB II project is to build on the work completed in PROLIMB I and develop and combine mechanistic models of hand motion and haptic sensing to deliver novel, affordable body-powered prosthetic fingertip digits with enhanced motion and sensation to address current clinical needs and support the quality of life of amputees. With collaboration from the University of Warwick (UoW) and University College London (UCL), Steeper Group and Naked Prosthetics the PROLIMB II study will aim to model, design, fabricate and validate a body-powered prosthetic fingertip digit with integrated sensory feedback. The University Hospital Coventry & Warwickshire (UHCW) will provide the clinical facility with which to assess the comfort, usability and acceptance of this prosthetic in the daily lives of patients with digit amputations. This project will be a proof of concept study with verification of the prosthetic in motion capture (gait) laboratories as well as the use of simple validation data collection over a longer period.
The purpose of this study is to compare the percentage of early micromibilisation in unicompartmental knee arthroplasties in robot-assisted technique vs standard technique.
To analyze the short and long term postoperative clinical outcome and patient satisfaction of silicone gel-filled testicular implants.
This study is part of the clinical evaluation of SEBBIN silicone gel-filled gluteal implants, included in the technical file of the device. The aim of the study is to gather additional data about the safety and effectiveness of the device.
