“…Although the CAD-CAM technique has already been well established in dentistry [46], the major drawback of this technique is the great waste of material upon machining since it is a subtractive manufacturing method. The waste corresponds to approximately 90% of the prefabricated block in some cases and leftovers from these are not reusable.…”

In this review, we first briefly introduce the general knowledge of glass–ceramics, including the discovery and development, the application, the microstructure, and the manufacturing of glass–ceramics. Second, the review presents a detailed description of glass–ceramics in dentistry. In this part, the history, property requirements, and manufacturing techniques of dental glass–ceramics are reviewed. The review provided a brief description of the most prevalent clinically used examples of dental glass–ceramics, namely, mica, leucite, and lithium disilicate glass–ceramics. In addition, we also introduce the newly developed ZrO2–SiO2 nanocrystalline glass–ceramics that show great potential as a new generation of dental glass–ceramics. Traditional strengthening mechanisms of glass–ceramics, including interlocking, ZrO2–reinforced, and thermal residual stress effects, are discussed. Finally, a perspective and outlook for future directions in developing new dental glass–ceramics is provided to offer inspiration to the dental materials community.

“…They can also be repaired using resin composites with cutback or adding techniques. 6 In addition, physical (color stability, water sorption, and water solubility) and mechanical (fracture resistant, wear, compressive strength, hardness, and elastic modulus) properties of resin composite blocks were found better than that of conventional resin composite due to their higher degree of polymerization. 3,7 Despite the abovementioned advantages, bonding failure in the cement interface due to high polymerization of resin composite blocks, discoloration, luster loss over time after restoration, and fractures are the problems that might be considered in their long-term clinical performance.…”

Objective The aim of this study was to evaluate the 2‐year clinical performance of computer‐aided design/computer‐aided manufacturing (CAD/CAM) resin composite inlay restorations in comparison with direct resin composite restorations. Materials and methods In 44 patients, 120 class II (mesio‐occlusal/disto‐occlusal) cavities were randomly assigned into two groups; CAD/CAM resin composite inlay group (Lava Ultimate), direct resin composite group (Clearfil Majesty Posterior). Clinical evaluations were performed after 1 week, 6 months, 1 year, and 2 years according to the FDI criteria. The data were analyzed using Friedman's ANOVA and Mann‐Whitney U tests (α = .05). Results In 41 patients, 114 restorations were evaluated at the second year (recall rate 93.2%). All restorations were ideal or clinically acceptable. At the first year, considering all criteria, there were no statistically significant differences between the groups. However, there was a significant difference in terms of surface luster at second year, in favor of inlay restorations (P = .015). The marginal staining of resin composites increased after 2 years (P = .046), but there was no significant difference between the groups. Conclusions Except the surface luster, 2‐year clinical performance of CAD/CAM resin composite inlay restorations was found similar to direct resin composite restorations according to FDI criteria Clinical Significance The clinical performance of CAD/CAM resin composite inlays was acceptable in class II cavities subsequent to 2‐year evaluation.

“…Digital workflows and use of different materials have been described in the literature to enhance the clinician's ability to better treatment plan and execute esthetic cases. 21,22 PMMA is among the many readily available materials for milling. Milled PMMA has better physical and optical properties than conventional PMMA resin and can be used for the provisionalization of any type of indirect restoration.…”

Objective There are multiple treatment options to enhance a patient's smile, from conservative bleaching procedures to composite resins, porcelain veneers, or full‐coverage crowns. Treating patients with porcelain veneers is a commonly used approach in esthetic dentistry. Provisional restorations for veneers can be time‐consuming to make and difficult to retain. This article illustrates a technique for fabricating indirect snap‐on provisional restorations for veneer cases, describing both analog and digital approaches. Clinical considerations The present article presents an alternative provisionalization technique using snap‐on restorations for dental veneers. Application of these techniques will allow for ease of cleansability by the patient leading to healthier soft tissues before the final cementation. Delivery of veneers is more predictable with healthy soft tissue, as bleeding and inflammation may affect the bonding process. Conclusions This technique is an effective provisionalization option in most veneer cases. This approach seems to be well accepted by patients and a good alternative in helping to maintain optimal gingival health with interim restorations before delivery. Clinical significance The use of snap‐on provisionals for veneer restorations will allow the clinician to have an efficient technique with better tissue response before cementation. This prevents inflammation and facilitates a controlled delivery process.
