The development of natural aesthetics has been facilitated by various innovative ceramic materials and techniques. Although metal-ceramic restorations have traditionally been the standard for durable and predictable restorations, the use of metal core materials may result in dense, opaque restorations. The incorporation of low-fusing porcelain materials has enabled the provision of translucent restorations that enable sufficient light transmission and strength. This article presents two comparative case reports that demonstrate the clinical application of a synthetic low-fusing quartz glass-ceramic material for the fabrication of aesthetic and functional metal-ceramic restorations.

Aim: To assess hard as well as soft peri-implant tissues within cases having two lost adjacent anterior teeth treated through placing either two implants with two separate crowns or only an implant along with a crown with a cantilever, and evaluating the effect of polyetheretherketone (PEEK) restoration on cantilever design up to 18 months after functional loading.
Materials And Methods: Twenty-seven participants (15 males and 12 females; mean age, 38.6 years; range 20-50 years) with missing two adjacent anterior teeth were treated with implant system (Flotecno implant system, Italy).

This study evaluated the effect of substrate core materials and occlusal contact patterns on the fatigue mechanical behavior and stress distribution of single-unit ceramic crowns. One hundred and twenty monolithic crowns were fabricated from zirconia (YZ - IPS e.max ZirCAD, Ivoclar), lithium disilicate (LD - IPS e.

Statement Of Problem: Harmony between prostheses and periodontal tissues is essential. The presence of a fixed prosthesis has been reported to increase the risk of periodontal lesion onset in abutment teeth and to affect longevity. However, studies comparing the supragingival plaque biofilm on fixed prostheses and natural teeth are lacking.

Metastable, , kinetically favored but thermodynamically not stable, interstitial solid solutions of carbon in iron are well-understood. Carbon can occupy the interstitial atoms of the host metal, altering its properties. Alloying of the host metal results in the stabilization of the FeC phases, widening its application.

Objectives: Numerous studies have been conducted on the adaptation of dental restorations fabricated by additive (AM) and subtractive manufacturing (SM); however, the results are conflicting. This systematic review and meta-analysis aimed to evaluate the fit and trueness of fixed restorations made by AM compared to SM.
Data: Studies investigating internal fit, marginal fit, and trueness of fixed prostheses were involved.
