NCT ID: NCT05252689 Completed - Clinical trials for Endodontically Treated Teeth

Clinical Evaluation of Teeth Prepared With Vertical Preparation Versus Deep Chamfer

Start date: March 1, 2020
Phase: N/A
Study type: Interventional

It has been demonstrated that a great amount of tooth structure is lost during the prosthetic preparations of abutments for full-coverage FDPs with tooth substance removal of 63% of 73%, this aggressive loss of tooth structure usually accompanied with pain and post-operative sensitivity. In comparison with the vertical preparation technique, there is less amount of tooth substance loss. this clinical study will provide benefits for practitioners and clinicians by guiding them to choose a more conservative treatment plan with the better marginal fit, clinical performance and satisfaction for the patients on the long term. rather than other benefits like less chair time, less risk for pulp injury, less time and cost

NCT ID: NCT03685513 Not yet recruiting - Clinical trials for Single Posterior Crowns

One Year Clinical Evaluation of Milled BioHPP Polyetheretherketone (PEEK)-Based Versus Metal Ceramic Single Crowns

Start date: January 1, 2019
Phase: N/A
Study type: Interventional

Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-colored systems as PEEK. BioHPP PEEK is 20% ceramic reinforced, semicrystalline, thermoplastic and radiolucent polymer for extreme durability especially for frameworks for fixed and removable dental prostheses. It has many advantages as low density, light weight, shock absorber, biocompatible and venerable with composite resin. The aim of this study is to evaluate the clinical performance of milled BioHPP PEEK-based single crowns and compare them to metal-based single crowns.
