“…All‐ceramic crowns have been used widely in dentistry with similar clinical success rate to metal‐ceramic crowns. Their survival rate in the anterior region after 11 years is 98.9% 26 . It has been reported that after 10 years of clinical service, need to re‐intervention without replacement in ceramic veneers occurs in 36% of ceramic veneers, and only 7% of ceramic veneers get a more invasive treatment approach.…”

Key Clinical MessageVeneer crowns can be used in anterior endodontically‐treated teeth with light occlusal force and enamel substrate consideration as a more conservative approach instead of conventional all ceramic crowns.AbstractAll‐ceramic anterior crowns and veneers have been used widely in dentistry with high clinical success rate. The development of new reinforced ceramics in recent years has led to more use of extended defect‐oriented preparation designs, that is, extended veneers, instead of full crown preparations which are less invasive. A veneer crown is simply a veneer that covers the entire tooth. The preparation preserves remaining enamel and uses a conservative preparation design. Its indication should be carefully raised taking into consideration various factors. The preparation design is crucial to ensure longevity of such restoration. The balance is between sufficient preparation for the material thickness and adequate strength against occlusal load and the enamel preservation. A 24‐year‐old man referred to the restorative department of the Dentistry School of Tehran University of Medical Sciences complaining from his poor esthetics in the maxillary incisors. In clinical and radiographic evaluation, he had open bite, composite discoloration due to corrosion of the pre‐fabricated posts in all four incisors, a periapical lesion in tooth 21 and under‐filled root canal therapy in tooth 22. All four posts and composite restorations were removed and teeth 21 and 22 were retreated. Although the amount of remaining tooth tissue was low, it had enough enamel thickness, especially in the buccal area. Taking into consideration this mixed enamel and dentin substrate, endodontics access, esthetics needs and canine guidance occlusion with no parafunction history, bonded lithium disilicate veneer crowns were selected to restore the maxillary incisors. A 12‐month follow‐up showed promising clinical (healthy gingival tissue and successful restorations) and radiographic (reduced periapical lesion) outcomes.

Aim: This study aimed at evaluating the impact of different adjustments and artificial aging on the color change (ΔE) and surface roughness (Ra) of monolithic zirconia (MLZ) and lithium disilicate (LD) ceramics. Materials and methods: Forty discs were prepared from two types of MLZs, including ceramill monolithic Zr (CM-Zr) and Prettau PSZ Zr (PP-Zr), and one LD (IPS e.max-LD, IPS-LD). After different clinical adjustments (performed with glazing, bur, bur + glazing, and bur + polishing) and artificial aging (in-vitro coffee immersion), the ΔE was assessed using a spectrophotometer. The roughness (Ra) was also evaluated after these adjustments. The ANOVA and multiple com-parisons test were used to compare the groups statisitcally and the level of significance was set at 5%. Results: In the CM-Zr group, the greatest ΔE was observed after bur adjustment (3.32, p < 0.05) while the lowest ΔE was seen after the glaze treatment (2.11, p < 0.05). In the PP-Zr group, the highest ΔE was observed after bur treatment (2.70, p < 0.05) while the lowest ΔE was seen after the glaze treatment (1.25, p < 0.05). Lastly, for the IPS-LD group, the highest ΔE was again observed after bur treatment (2.91, p < 0.05) while the lowest ΔE was seen after glaze treatment (1.0, p < 0.05). After coffee immersion, it was observed that the highest overall ΔE was observed for CM-Zr after the bur and polish treatment (3.45), while the lowest overall ΔE was observed in IPS-LD after the glaze treatment (2.10). All the ΔE values were within the clinical acceptable range. The highest overall Ra was witnessed for CM-Zr after bur adjustment (1.64), while the lowest overall Ra was seen for IPS-LD after glaze treatment (0.26). Different clinical adjustments and artificial aging influence the colour stability of different ceramic materials (CM-Zr, PP-Zr, and IPS-LD). Compared to the MLZ, IPS-LD ceramics were more stable as they presented with lower ΔE after surface adjustments and coffee immersion. Conclusions: The surface adjustment that minimally affected the colour of these ceramics was glaze treatment, while the ceramics were most affected by bur adjustments. Coffee aging affected colour stability of all ceramic materials. IPS-LD ceramics presented the lowest Ra values after different clinical adjustments.
