“…The longitudinal effectiveness of the MR IFCDPs against maxillary complete dentures has been demonstrated in the literature, with considerably high rates of technical complications like wear and chipping encountered as a result of material fatigue and stress . Studies have also reported on the incidence of complications with ceramic type IFCDPs . While no studies have been identified directly comparing intra‐group ceramic IFCDPs to MR IFCDPs, it must be mentioned that there is paucity of reports on complications with ceramic IFCDPs for edentulous jaws with observation periods of at least 5 years conversely with the MR design …”

Purpose:To report the rate of technical complications and prosthesis survival in a cohort of edentulous patients treated with implant-supported fixed complete dental prostheses (IFCDPs) after a mean observation period of at least 1 year. Materials and Methods: The single-visit examination included clinical and radiographic assessment, occlusal analysis, photographs and questionnaire assessing patient satisfaction in a cohort of 52 patients rehabilitated with 71 IFCDPs (supported by 457 implants). The IFCDPs were assessed for technical complications, number of implants and cantilever extension, retention type and prosthetic material type. Comparison was made between ceramic IFCDPs (Group 1) and metal-resin IFCDPs (Group 2). Kaplan-Meier survival curve analysis was carried out for assessment of prosthesis survival and was done for both Groups 1 and 2 separately. The Cox proportional hazard model was used for survival analysis, adjusting for a number of potential confounders, to evaluate the association between prosthesis survival and several risk factors such as type of opposing occlusion, nightguard use, and presence of bruxism. Responses to patient satisfaction questions were compared with Fisher's exact test. Results: Out of 71 edentulous arches (52 patients) restored with IFCDPs, 6 IFCDPs had failed, yielding a cumulative prosthesis survival rate of 91.6 % after a mean observation period of 5.2 years (range: 1-12 years) after definitive prosthesis insertion. Three IFCDPs were lost due to implant failures after 5.8 to 11 years of functional loading. Additionally, 3 metal-resin IFCDPs failed due to technical complications. Minor complications were the most frequent complications observed, namely wear of the prosthetic material (9.8% annual rate) being the most common, followed by decementation of cement-retained IFCDPs (2.9%), and loss of the screw access filing material of the screw-retained IFCDPs (2.7%). The most frequently observed major complication was fracture of the prosthetic material (1.9% annual rate), followed by fracture of occlusal screw (0.3%), and fracture of framework (0.3%). The annual rate of wear of prosthetic material was 7.3% for porcelain IFCDPs (n = 19/55) and 19.4% for metal-resin IFCDPs (n = 13/16), yielding a statistically significant difference between the 2 groups (p = 0.01). Conclusions: After a mean exposure time of 5.2 years, 91.6% prosthesis survival rates were achieved (65 out of 71 IFCDPs). The most frequent minor technical complication was wear of the prosthetic material with estimated 5-year rate of 49.0%, while the most frequent major complication was fracture of the prosthetic material with estimated 5-year dental unit-based rate of 9.5%. The cumulative rates for "prosthesis free of minor complications" at 5-and 10-years were 60.5% (95% CI: 47.2-71.3%) and 8.9% (95% CI: 2.9-18.0%), respectively. The cumulative rates for "prosthesis free of major technical complications" at 5-and 10-years were 85.5% (95% CI: 73.0-92.5%) and

“…The treatment modality of using MR IFCDPs has been well documented longitudinally, and increased technical complication rates in terms of chipping and wear have been reported. Regarding MC IFCDPs, Wong et al's systematic review reported that porcelain veneer fracture was the most common technical complication in studies with at least a 5‐year follow‐up …”

Purpose To retrospectively assess complications and clinical and radiographic outcomes of edentulous patients treated with double full‐arch implant‐supported fixed complete dental prostheses (IFCDPs) after a mean observation period of 5.1 years. Materials and Methods The single‐visit clinical and radiographic examination included medical and dental history review and clinical assessment of biologic and technical complications encountered with all implants and IFCDPs. Life table analysis and Kaplan‐Meier survival curves were calculated. Analysis was conducted to evaluate the association between prosthesis survival and several risk factors such as type of opposing occlusion, nightguard use, and presence of bruxism. Results Nineteen edentulous patients restored with 38 IFCDPs were included. A total of 249 implants were placed and 2 implants failed after a mean observation period of 5.1 years (range: 1‐12 years), yielding an overall implant survival rate of 99.2% and prosthesis survival rate of 92.1%. Three out of 38 IFCDPs were lost, 1 after implant losses and 2 due to technical complications. The most frequent minor biologic complication was soft tissue recession with an estimated 5‐year rate of 45.5% (95% CI: 39.4‐57.5), while the most frequent major complication was peri‐implantitis with an estimated 5‐year implant‐based rate of 9.5% (95% CI: 6.7‐11.3). The most frequent minor technical complication was wear of the prosthetic material with an estimated 5‐year rate of 49.0% (95% CI: 37.4‐76.4), while the most frequent major technical complication was fracture of the prosthetic material with an estimated 5‐year dental unit‐based rate of 8.0% (95% CI: 6.6‐10.1). Conclusions After a mean use time of 5.1 years, high implant and prosthesis survival rates were observed. The most frequent major biologic complication was peri‐implantitis, and the most frequent major technical complication was fracture of the prosthetic material. The 5‐year estimated cumulative rates for “prosthesis free of biologic complications” was 50.7% (95% CI: 33.7‐65.4) and for “prosthesis free of technical complications” was 57.1% (95% CI: 39.3‐71.5).

“…Moreover, layered restorations showed 5-year success rates significantly lower than monolithic prostheses (i.e. 60.4% vs 90.9%) [169]. Consequently, the use of full-arch, extended zirconia restorations should always be carefully evaluated and further long-term clinical studies are necessary to validate the effectiveness of their serviceability.…”

Background: The introduction of the new generation of particle-filled and high strength ceramics, hybrid composites and technopolymers in the last decade has offered an extensive palette of dental materials broadening the clinical indications in fixed prosthodontics, in the light of minimally invasive dentistry dictates. Moreover, last years have seen a dramatic increase in the patients' demand for non-metallic materials, sometimes induced by metal-phobia or alleged allergies. Therefore, the attention of scientific research has been progressively focusing on such materials, particularly on lithium disilicate and zirconia, in order to shed light on properties, indications and limitations of the new protagonists of the prosthetic scene. Methods: This article is aimed at providing a narrative review regarding the state-of-the-art in the field of these popular ceramic materials, as to their physical-chemical, mechanical and optical properties, as well as to the proper dental applications, by means of scientific literature analysis and with reference to the authors' clinical experience. Results: A huge amount of data, sometimes conflicting, is available today. Both in vitro and in vivo studies pointed out the outstanding peculiarities of lithium disilicate and zirconia: unparalleled optical and esthetic properties, together with high biocompatibility, high mechanical resistance, reduced thickness and favorable wear behavior have been increasingly orientating the clinicians' choice toward such ceramics. Conclusions: The noticeable properties and versatility make lithium disilicate and zirconia materials of choice for modern prosthetic dentistry, requiring high esthetic and mechanical performances combined with a minimal invasive approach, so that the utilization of such metal-free ceramics has become more and more widespread over time.

Prosthodontic Complications of Metal‐Ceramic and All‐Ceramic, Complete‐Arch Fixed Implant Prostheses with Minimum 5 Years Mean Follow‐Up Period. A Systematic Review and Meta‐Analysis

Abstract: MC and AC CFIDPs presented with veneer fractures as primary complication. This may require significant maintenance. Other complications were negligible after a mean follow-up period of at least 5 years. More long-term studies, especially on all-ceramic CFIDPs are needed.
