Filter by:Tooth loss is a major chronic problem in dentistry and edentulous elderly endures poorer quality of life worldwide. Removable partial dentures (RPDs) are the most widely accepted and cost-effective treatment for patients to restore oral functions. RPDs contain three components including the metal framework, denture base and acrylic teeth. Conventionally, RPD fabrication involves tedious clinical and dental laboratory procedures and is time consuming, labour-intensive, and often imprecise, therefore incapable of meeting the growing demands of RPD by an ageing population. The challenges to achieve a high quality and high-throughput RPD service lie in three aspects: 1) accuracy in capturing oral profile; 2) immediate oral information analysis and device design, and 3) automation in production.
This study aims to compare oral health-related quality of life and retention between digitally- fabricated temporary flexible RDPs and conventionally-fabricated temporary flexible RDPs.
The present retrospective study aims to evaluate the impact of cantilever design in the posterior areas of the mandible on clinical, radiographic, and volumetric parameters with an 8-year follow-up.
The goal of this clinical trial is to compare the placement accuracy in immediately placed implants using dynamic navigation between deep-threaded and regular-threaded implants in partially edentulous patients. The main question it aims to answer is: is there a difference in implant placement accuracy between deep-threaded and regular-threaded implants using dynamic navigation? Participants will receive implants placed immediately under dynamic guidance. Researchers will compare type of implant thread (Straumann BLT versus Straumann BLX) to see if there are significant differences in placement accuracy.
In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.
The goal of this clinical trail is to evaluate the clinical, radiological and immunological outcomes of the one-piece zirconia abutments (OPZAs) and two-piece zirconia abutments (TPZAs) with friction-fitted titanium bases in single implant crowns in aesthetic region. The main question it aims to answer is: whether the mechanical properties of one-piece zirconia abutments are the same as those of two-piece zirconia abutments. Participants who have two missing teeth in aesthetic region will receive the OPZAs for one restoration and the TPZAs for the other. Researchers will compare OPZAs group (OG) and TPZAs group (TG) to see the clinical, radiological and immunological outcomes of the two.
The aim of the present prospective randomized controlled study is to compare the clinical, radiological, micro-circulation, and histology of a novel, semi-thick, and conventional full-thickness mucoperiosteal flap technique during horizontal alveolar ridge augmentation.
Fifteen partially edentulous patients received 34 implants and were provided 16 zirconia fixed partial prostheses (FPPs) with one cantilever extension replacing mandibular or maxillary missing posterior and lateral teeth. Patients were re-examined up to 4 years.
The main aim of this clinical trial is to analyze the survival rate of short-length implants (<4.5 mm) in partial edentulism subjects. 6.5 mm length implants will be used as control arm. Additionally, others clinical parameters (marginal bone loss and prosthetic associated complications) will be measured.
The main aim of this prospective study is to analyze the survival rate of short-length implants (<6.5 mm) in subjects with partial edentulism. Non-short length implant will be used as control arm. Additionally, others clinical parameters (marginal bone loss and prosthetic associated complications) will be measured.
