One-piece zirconia implants are recommended only in certain clinical conditions, while there are no sufficient data regarding two-piece zirconia implants to recommend their clinical use without caution.

Īccording to the Group 2 ITI Consensus Report for Prosthodontics and Implant Dentistry of May 2018, zirconia can be used as either a fixture material or a prosthetic material. Moreover, zirconia showed good biocompatibility and high flexural strength, together with less accumulation of dental plaque and resistance to staining compared to resinous materials. Zirconia is a material widely used for fixed prostheses supported by natural teeth or implants, with excellent results over time. On the other hand, they are characterized by relatively high rates of complications such as teeth debonding from the structure, fractures, and screw/abutment loosening. Some of the most commonly used materials for ISFCDPs are metal-acrylic hybrids, where acrylic resin teeth and gingival tissue are cemented on a metal framework these materials are easy to use, affordable, and can be easily repaired. In implant prosthodontics, the result of a fixed full-arch rehabilitation depends on multiple factors: some are related to the fixtures, such as fixture material, surface characteristics, positioning, and type of connection to prosthetic components others are related to the prostheses, such as design and materials used. įor this reason, according to some authors, ISFCDPs should be considered the gold standard of care, especially in clinical scenarios characterized by severe atrophy of the alveolar bone. The advantages offered by ISFCDPs are multiple, ranging from the improvement of patients’ comfort to the preservation of the alveolar bone from the mechanical stress of removable dentures, among others. Nowadays, thanks to the high survival and success rates of dental implants, implant-supported fixed complete dental prostheses (ISFCDPs) or implant-retained removable dentures have become a valid alternative to complete removable dentures to overcome the above-mentioned issues. ĭespite many patients still accepting complete dentures for financial or personal reasons, some physiological modifications of the normal anatomy of the maxillary and mandibular bones, such as severe alveolar bone resorption, could lead to difficulties in prosthetic retention, which in turn causes pain and difficulties in chewing and eating properly. īefore the advent of implant dentistry, the only therapeutic option to treat complete edentulism was to manufacture complete removable dentures. The increasing aging of the population worldwide has led to a major proportion of patients who could develop complete edentulism and consequently need prosthetic rehabilitation, which can be an actual challenge for clinicians. According to the results of this review, the use of zirconia for ISFCDPs showed good clinical outcomes, with high survival rates ranging from 88% to 100% and prosthetic complications that were restorable by the clinicians in most cases. The objective of the present narrative review was to search the literature for studies regarding the clinical performance of zirconia-based ISFCDPs. Since CAD/CAM technology and zirconia are being continuously innovated to achieve better results and performances over time, a narrative review of the literature seems necessary to focus research efforts towards effective and durable solutions for implant-supported, full-arch rehabilitations. Regarding the use of zirconia for ISFCDPs, the 2018 ITI Consensus Report stated that “implant-supported monolithic zirconia prostheses may be a future option with more supporting evidence”. Zirconia is a material widely used in fixed prosthodontics, whether on natural teeth or on implants, with excellent results over time.

The success of implant-supported fixed complete dental prostheses (ISFCDPs) depends on multiple factors: some are related to the fixtures, such as fixture material, surface characteristics, positioning, and type of connection to prosthetic components others are related to the prostheses, such as design and materials used.
