Survival and Fracture rates of One-Piece Zirconia Implants: A Systematic review

Abstract

Introduction: The implementation of endosseous showed expected outcomes related to survival and successful oral management. Nowadays, interest in achieving an excellent esthetic outcome increased in implant dentistry. Dental implants’ aesthetic outcomes demand understanding of fundamental biological principles and proficiency in various surgical procedures. Titanium alloys and titanium are the gold standards as a material of choice. Evaluate the rate of survival and fracture by dental implants of one-piece zirconia with a year follow-up history. Methodology: This study was based on a systematic review, carried out through PubMed, Embase and Medline databases considering clinical studies only from 2016–2022 published data. Results: Eleven articles were selected out of 1024 initially. Evaluated a total number of 658 one-piece implants, with follow-ups from 1–7 years. The comprehensive survival and fracture rate of one-piece zirconia implants is 87.7 % and 4.9% after at least a year of function. Z-system Zirconia implants showed the highest fracture rate among other systems. Conclusion: Zirconia dental implants are a promising solution to replace missing tooth/teeth, especially in the case of Titanium allergy, or in patients with sub-optimal soft tissue conditions can lead to poor esthetic results. However, more clinical practice is required to determine the effective implants with fewer complications.
