Comparative Performance of Two-piece Zirconia Tissue Level Implants vs. Titanium Bone Level Implants Using a Fully Digital Workflow 5-year Follow-up of a Randomized Clinical Trial

What this Trial Is About

Researchers are evaluating the medium-term performance and safety of two types of dental implants: the Straumann PURE 2-piece Ceramic Implant made of zirconia and the Straumann Bone Level Implant made of titanium. The study aims to compare these implants using a fully digital workflow to understand their biological and technical complications, patient satisfaction, and aesthetic outcomes over a five-year period. Titanium implants have a metallic color that often requires deeper placement, which can complicate hygiene, while zirconia implants offer a color closer to natural teeth. Participants will receive either the zirconia ceramic implant or the standard titanium implant placed in healed extraction sites in the premolar-to-premolar area of the upper or lower jaw for single tooth replacement. After implant placement, prosthetic loading with a definitive crown will occur following a six-month healing period. Both groups undergo routine treatment, with the only difference being the implant material. The surgical approach follows guidelines for healed extraction sites approximately 16 weeks after tooth loss. During the five-year follow-up after implant loading, participants will attend scheduled visits where researchers will measure bone level changes, implant survival rates, and complication-free survival. Patient satisfaction and oral health impact will also be assessed using questionnaires. Data will be collected and analyzed to compare long-term implant performance and safety. Participation involves regular evaluations to monitor outcomes and ensure safety throughout the study duration.
