“…The authors discussed that this could be due to the inaccuracy of the early CAD/CAM procedures. In later studies the marginal discrepancy or degradation have also been seen but to a smaller extent [1,16]. In the present study the marginal discrepancy was larger with zirconia FDPs, where the majority of the restorations (17/23) received USHPS rating of B (slight probe catch with no gap) and 3/23 of the FDPs received rating of C (gap with some dentine or cement exposure).…”

“…Chippings of the veneering porcelain seems to be a common complication of zirconia FDPs [1,11,16,[18][19][20]. It is seen in metal-ceramic FDPs as well [1,29], but the major fractures of the veneering porcelain have only been seen in zirconia FDPs [1].…”

“…The zinc phosphate cement should not be recommended at all due to unfavorable properties such as brittleness and water-solvability [37]. In the study of Rinke and co-workers the zirconia FDPs showed increased rates for loss of retention and marginal secondary caries that could be due to semi-optimal fit of the restorations (early CAD/CAM system) and using the zinc phosphate cement [16]. In the present study, five different cements were used and none of the frameworks were treated with air-borne particle abrasion.…”

“…In previous studies, the technical and biological complications seen with zirconia single crowns and FDPs are framework fractures, chipping of the veneering ceramic, secondary caries, loss of vitality of the abutment tooth, marginal discoloration and loss of retention [1,2,16,17]. Compared to other dental materials, the most common clinical problem with zirconia FDPs appears to be the chipping and fractures of the veneering ceramic [2], varying between 15-32 % during 5-10 years of follow-up time [11,[18][19][20].…”

“…More information about clinical outcomes of zirconia FDPs is still needed, especially when some of the existing studies are about the early-stage CAD/CAM procedures [16,20] and by far there is more knowledge on how to better avoid material related problems like porcelain chipping. The aim of this retrospective study was to evaluate the survival of tooth-supported single crowns and multi-unit zirconia FDPs, and the outcomes of technical and biological complications after 2-8 years of clinical service.…”

The aim of this retrospective clinical study was to evaluate the survival and the occurrence of technical and biological complications of zirconia crowns and fixed dental prostheses made in the student clinic of Turku University, Finland, between April 2009 and September 2017. Materials and methods: Twenty-seven patients (19 female, 8 male), with zirconia crowns or FDPs, participated in the follow-up investigation. The mean age of patients was 64.6 years. Of the 40 restorations, 17 were single crowns and 23 FDPs. Twenty-seven restorations were anterior and 13 posterior. Restorations were investigated according to modified USPHS criteria. Results: The survival rate of zirconia restorations after 2-8 years (average 5.7 years) of clinical use was 95%. Survival rate of single crowns was 94.2% and of FDPs 95.7%, respectively. The overall complication rate was 26% for FDPs and 5.8% for crowns. One posterior crown was lost due to a vertical root fracture and one FDP showed a framework fracture. Veneering ceramic fractures were detected in 12% of all cases (0% for crowns and 22% for FDPs). Bleeding on probing was present in 38.1% of restored teeth and 13.9% of control teeth. Embrasure space was insufficient in 52% of zirconia FDPs and 81% of these restorations showed elevated BOP values. Conclusions: Zirconia crowns and FDPs survived well in this retrospective follow-up study. Chipping of veneering ceramic and bleeding on probing were the most common complications. Thick connector areas made according to material demands resulted in insufficient embrasure spaces and inflammation of marginal gingiva.
