“…Monolith zirconia’s choice for posterior teeth could be due to its high flexural strength and fracture resistance compared to the inherently brittle feldspathic porcelain, or concern of about wearing of opposing natural teeth by feldspathic porcelain [ 5 , 24 ]. A similar choice of zirconia for fabricating posterior crowns was also seen among 277 respondents in a study conducted by the ADA panel [ 25 ]. In fact, a study conducted in 2013, among dental schools in America suggested the shift of material preference from feldspathic porcelain to zirconia (80%) within a span of 10–15 years due to greater strength and clinical longevity similar to PFM [ 26 , 27 ].…”

Background Material selection is crucial in restorative dentistry, influenced by aesthetics, material properties, and tooth location. This understanding is key for advancing dental practices and patient outcomes. The present study aimed to assess dentists’ preferences for restorative materials in single-tooth crowns (SC) and how abutment tooth location and preparation margins influence these choices. Material/Methods A web-based pre-validated questionnaire survey was conducted among 811 actively practicing dentists in Saudi Arabia. Results In posterior teeth, we found that ceramic was the most preferred material for SC regardless of the abutment tooth location and location of margins, followed by porcelain fused to metal (PFMs). In anterior teeth, ceramics were preferred, followed by CAD/CAM-based resin SC. Among the choice of ceramics in teeth for both supra-gingival margins, monolith zirconia was the most-preferred material for SC fabrication in posterior teeth, followed by zirconia-reinforced lithium silicate ceramic. Similarly, for sub-gingival margins, monolith zirconia crowns were the most popular option in posterior teeth among the respondents, with the highest in the mandibular molar region. In the anterior region, layered zirconia was the least preferred, and lithium disilicate ceramics was the most-favored option. A statistically significant difference existed between supra- and subgingival preparation for teeth 11 ( P =0.01), 16 ( P =0.03), and 34 ( P =0.02). Conclusions Ceramic was the material of choice among Saudi dentists for replacement of SC, irrespective of the location and preparation margin. Monolith zirconia was usually selected for posterior teeth and lithium disilicate ceramics was the top choice in anterior teeth.

Objectives The aim of this study was to evaluate the clinical performance and possible complications of single zirconia crowns fabricated using an intraoral digital computer-aided design-computer-aided manufacturing (CAD-CAM) protocol in normal and dysfunctional patients after 3 years of follow-up. Materials and Methods Seventy patients were included in this study. The teeth were prepared with a knife-edge marginal design, and temporary crowns were placed. Digital impressions were taken using optical scanning, and the frameworks were milled using the same technology. The veneering process was performed by the same dental technician. The occlusal corrections were made before cementation. The outcomes were evaluated in terms of survival, failures, and complications. The marginal adaptation of the crowns was also assessed. Results The digital protocol for single zirconia crowns resulted in satisfactory outcomes, with high rates of survival and minimal complications after 3 years of follow-up. The marginal adaptation of the crowns was excellent, with 93% of the restorations achieving the ideal marginal adaptation, while 7% had minor deviations. Parafunctions were found in 41.9% of the prosthetic rehabilitation, but no significant differences were observed between the normal and dysfunctional groups regarding the survival and complications of the crowns. Conclusion The digital protocol for single zirconia crowns is a reliable and predictable treatment option, even for patients with parafunction, when proper occlusal corrections are performed before cementation. The use of intraoral digital CAD-CAM technologies with optical impressions can simplify procedures, reduce the workflow time, and minimize the variables linked to the human factor.

“…Along with the higher cubic phase, clinicians have managed to overcome the difficulty of achieving adhesion between dental tissues and zirconia ceramics with the help of new adhesion techniques and resin cement containing adhesive monomers that can promote chemical adhesion through the reaction between acidic functional and oxide groups on the zirconia surface (Chen et al, 2014;Quigley et al, 2021). The above resulted in the clinical use of zirconia for esthetic anterior cases (Naveau et al, 2019) or as a material for anterior veneers (Lawson et al, 2021). Along with the use of multi-layered translucent monolithic zirconia ceramics, several other materials are included in the armamentarium of a CAD/CAM dental clinic.…”

This study investigates the influence of acid exposure and thermocycling simulating erosion tooth wear, on the optical properties and surface roughness of chairside materials. Resin‐ceramic, lithium disilicate, premium zirconium oxide and resin composite material comprise the materials tested. To simulate the dental erosion and aging, specimens from each material were immersed in hydrochloric acid, while the thermocycling procedure included 10,000 cycles. The translucency, the color differences and the surface roughness were calculated. The materials phase composition was tested using X‐ray diffraction analysis to evaluate T‐M phase transformation. The CIEDE2000 color difference and the translucency parameter were tested different significantly among groups. Data were statistically analyzed via independent samples t‐test, and paired samples t‐test. The thermocycling procedure and the exposure to the acid solution had different effect on the surface roughness of CAD/CAM materials. The present result demonstrated the negative effect the acid exposure has on the zirconia material in terms of color difference. However, no color differences over the threshold of acceptability were recorded after the thermocycling procedure. Both polymer materials exhibit an increase of the surface roughness when they were immersed in acid but they did not display an increase in roughness when they were thermocycled.
