Active clinical trials for "Prosthesis Failure"

The goal of this study is to evaluate the outcome of a Poly-ether-ether-ketone - used in single teeth implant-supported rehabilitations after one year of follow-up. The main question it aims to answer is: - What is the survival outcome of single teeth implant-supported prosthesis using Poly-ether-ether-ketone? The participants already rehabilitated with a single tooth dental implant will receive a definitive prosthesis incorporating Poly-ether-ehter-ketone.

The goal of this study is to evaluate the outcome of a Poly-ether-ether-ketone - acrylic resin prosthesis for full-arch rehabilitation of the atrophic maxillae through the All-on-4 Hybrid concept (standard and zygomatic implants) after one year of follow-up. The main question it aims to answer is: - What is the survival outcome of the full-arch implant-supported Poly-ether-ether-ketone - acrylic resin prosthesis? The participants already rehabilitated with dental implants will receive a Poly-ether-ehter-ketone prosthesis as a definitive prosthesis.

The goal of this observational study is to evaluate the outcome of a Poly-ether-ether-ketone - acrylic resin removable partial denture used in partial edentulous rehabilitation after one year of follow-up. The main question it aims to answer is: - What is the survival outcome of partial rehabilitations using Poly-ether-ether-ketone-acrylic resin removable partial dentures? The participants will receive a definitive removable partial denture incorporating Poly-ether-ehter-ketone.

The aim of this clinical study will be the effect of geometric modifications of implant scan bodies compared to conventional transfer techniques on passivity of all on four mandibular restorations

The treatment with transcatheter aortic valve implantation (TAVI) of patients with small (≤23mm) surgical bioprostheses remains a challenge due to the increased transvalvular residual gradients and high rates of severe prosthesis-patient mismatch (PPM) following the procedure.

This clinical study will aim to compare and evaluate zygomatic implant stability, occlusal contact, and bone level changes around dental implants

This retrospective study investigates the longevity of dentures with SR Phonares II teeth after a wearing period of more than 10 years. The primary objective is to assess the survival rate of dentures with SR Phonares II teeth after more than 10 years. The secondary objectives asses the quality of the dentures concerning aesthetic, functional and biological properties.

The purpose of this study is to compare the percentage of early micromibilisation in unicompartmental knee arthroplasties in robot-assisted technique vs standard technique.

The goal of this observational study is to evaluate the outcome of a Poly-ether-ether-ketone - acrylic resin prosthesis for full-arch rehabilitation of the atrophic maxillae through the All-on-4 concept after five years of follow-up. The main question it aims to answer is: - What is the survival outcome of the full-arch implant-supported Poly-ether-ether-ketone - acrylic resin prosthesis? The participants already rehabilitated with dental implants will receive a Poly-ether-ehter-ketone prosthesis as a definitive prosthesis.

Newly available ceramic CAD-CAM blocs containing a screw channel for chairside-made crowns to be adhesively cemented to a TiBase abutment and screw-retained to an implant are appealing to the clinician, considering the time efficiency (one appointment) and overall lower costs as no dental laboratory is involved. The hypotheses are that the biological (BOP, PD, PCR, implant bone level) and mechanical outcomes (fracture, loss of retention, wear) are equivalent to implant screw-retained Porcelain-Fused-to-Metal (PFM) crowns over a 5 year observation time.This RCT will provide key information as to the cost/benefit, suitability and/or limitations of these chair-side hybrid-abutment crowns in the posterior region.
