“…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].…”

“…These findings are in line with previous literature. Some studies report bleeding on probing as a common biologic complication related to zirconia restorations [18,40]. In other studies, however, no elevated counts in the periodontal parameters have been seen [1,41].…”

“…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]. In the study of Teichmann and co-workers the chippings were seen frequently after the 8-year recall [18].…”

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.

“…Ultimately, the non-uniform structures and physical aspects between natural teeth and restorative materials result in different degrees of wear [3]. A number of studies have evaluated the long-term clinical behavior of ceramics [29][30][31], but studies on the loss of the vertical dimension are limited [32].…”

BackgroundThe abrasion behavior of various ceramics is rarely investigated, though it is relevant for the clinical success of such restorations. The aim of this in vivo study was to evaluate the wear of glass-ceramic-veneered zirconium oxide frameworks over a period of 10 years.MethodsThe abrasive behavior of the restorations was examined in a total of 15 patients after a period of 3, 5, and 10 years using plaster models, which were then subjected to a scanning process on the Atos II industrial scanner and digitized for three-dimensional evaluation of the abrasion by the corresponding software (ATOS Professional 7.6). The individual post-examination models were compared to the baseline model and deviations calculated in the sense of the largest, punctual loss of material in millimeters ("minimal distance"), the average abrasion in millimeters ("mean distance"), and the volume decrease in cubic millimeters ("integrated distance"). Statistical analyses were performed using the Wilcoxon sign rank test or mixed regression models. Multiple testing was considered by Benjamini-Hochberg correction. The significance level was set at 0.05.ResultsWe found steadily increasing wear of the ceramic. The average volume decrease was significant (P < 0.001) at 3 years and 10 years (-3.25 mm3 and − 8.11 mm3, respectively).ConclusionsDespite the increasing wear of the glass-ceramic-veneered zirconium oxide frameworks in this study, the use of this class of materials can be regarded as clinically acceptable.This study is registered in DRKS - German Clinical Trials Registerwith the Register number 00021743

To investigate how patterns generated by femtosecond (fs) laser and femtosecond laser power affect the surface roughness (Ra) and biaxial flexural strength (BFS) of monolithic zirconia. Eighty disk‐shaped zirconia specimens were divided into eight subgroups (n = 10): Control (C), airborne‐particle abrasion (APA), 400 mW fs laser (spiral [SP(400)], square [SQ(400)], circular [CI(400)]), and 700 mW fs laser ([SP(700)], [SQ(700)], [CI(700)]). Ra values were calculated by using a surface profilometer. One additional specimen per group was analyzed with scanning electron microscopy and x‐ray diffractometry. BFS values were obtained by using the piston‐on‐3‐ball test. One‐way ANOVA and either Tukey's HSD (BFS) or Tamhane's T2 (Ra) tests were used to evaluate data (α = 0.05). Regardless of the pattern and power, fs laser groups had higher Ra than C and APA, while SP groups had lower Ra than CI and SQ groups (p ≤ 0.004). For each pattern, Ra increased with higher laser power (p < 0.001), while the laser power did not affect the BFS (p ≥ 0.793). CI and SQ groups had lower BFS than the other groups (p ≤ 0.040), whereas SP groups had similar BFS to C and APA (p ≥ 0.430). Fs laser microstructuring with spiral surface pattern increased the Ra without jeopardizing the BFS of zirconia. Thus, this treatment might be an option to roughen tested zirconia.

Ten-year survival and chipping rates and clinical quality grading of zirconia-based fixed dental prostheses

Abstract: The outstanding mechanical properties of zirconia-based systems have contributed to the belief that all-ceramics are a reliable material for prosthetic restorations. However, only long-term reports (such as this one) provide more detailed information on actual clinical efficacy.
