Dental Implants Clinical Trial
Official title:
Comparative Performance of Two-piece Zirconia Tissue Level Implants vs. Titanium Bone Level Implants Placed With a Fully Digital Workflow - 5-year Follow up of a Randomized Clinical Trial
A post-market, randomized-controlled, superiority clinical study to compare medium-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow.
Dental implants are a key modality for tooth replacement. Titanium dental implants have been the mainstay of dental implants as it osseointegrate well. Titanium has a silver gray metallic color and therefore, to hide its presence and enhance the aesthetic appearance, the implant is usually placed deeper into the bone tissue and the gums. This has negative consequences since it becomes more difficult to keep the interface between the dental implant and the crown free from bacterial plaque and inflammation. The use of zirconia（a base form of metal with similar properties of titanium in terms of osseointegration) has attracted a lot of interest because of its color that is similar to the one of natural teeth.This study will hence compare the long term performance of standard 4th generation dental implants made of titanium with a second generation zirconia dental implant. The study will evaluate the occurence of biological and technical complications; patient satisfaction and with the aesthetics of the tooth replacement over time. ;
