“…The occlusal surface was reduced by 2 mm (20, 21) to follow the required thickness of the different materials and to ensure an inherent stability of each restoration. To facilitate the try‐in procedure the cavity walls as well as the outer palatal surface were prepared with an overall angle of 6° towards the occlusal aspect (22, 23). Cavity wall angulations between 6° and 10° induced appropriate retention values for ceramic restorations without compromising the vitality of the pulp (22, 23).…”

This in vitro study evaluated the failure load of partial coverage restorations (PCR) made of various materials cemented on natural molars after exposure to the mastication simulator. Sixty-four maxillary molars were divided into four groups of 16 test specimens each. The specimens in one group remained unprepared (group NP); the teeth in the other groups were prepared equally according to standardized guidelines and restored with the following PCR: Group GO (Gold-Pontor-MPF; Metaux Precieux SA, Metalor, Neuchatel, Switzerland), group TA (Targis; Ivoclar Vivadent AG, Schaan, Liechtenstein) and group EM (IPS-Empress; Ivoclar Vivadent AG). The restorations in group GO were cemented conventionally, while those in groups TA and EM were luted adhesively. Groups NP and GO served as control groups. All test specimens were subjected to 1.2 million cycles (F = 49 N) in a mastication simulator. Subsequently, all test specimens were loaded occlusally until fracture occurred using an universal testing machine. All specimens withstood the masticating simulation. The median (IQR = x(0.25)-x(0.75)) failure loads were as follows: group NP: 1960.3(1480.5-2227.5) N, group TA: 1478.6(1293.4-1856.7) N and group EM: 1400.1(1043.1-1721.6) N. All test specimens of group GO achieved fracture strength values which exceeded a fracture load of 5500 N. The values of group GO were statistically significantly higher than those of groups NP, TA and EM (P < 0.00001). Furthermore, the results of group NP were significantly higher (P = 0.0226) than those of group EM. The results of groups NP and TA (P = 0.2022) as well as of groups TA and EM (P = 0.5340) did not differ significantly. The median values of all PCR systems obtained were within the limits of clinical acceptance. Long-term clinical investigations which take additional parameters into consideration are required before the composite-based Targis(R) (Ivoclar Vivadent AG) material can be recommended for indirect PCR.

“…The IPS-Empress system was developed at the University of Zurich, Zurich, Switzerland, in 1983 (1). Ivoclar Vivadent took over the development project in 1986 and presented it to the dental community in 1991 (3). The material used in the IPS Empress® system is a leucite-reinforced castable glass ceramic designed primarily for single-unit restorations (1,3,9).…”

“…Recent innovations in adhesive systems and ceramics technology have enabled the fabrication of ultraconservative bonded restorations that are biologically compatible (2) with improved esthetics and increased strength (3). Indirect adhesive restorations allow dental professionals to re-establish the function, shape and contour of the teeth, to replicate color, to achieve natural light transmission, and to recapture strength and aesthetics through conservative adhesive tooth preparation designs (1,2,4).…”

Rehabilitating Form, Function and Natural Aesthetics with Onlay Ceramic IPS Empress Esthetic®: Evidence and Versatility

Clinical research and in vitro laboratory tests have enabled the development and improvement of dental ceramics. Comprehension of the physical and mechanical properties of this material is essential, in order to ensure a functional, aesthetic and long-lasting posterior ceramic restoration. The clinical protocol for onlay preparation involves important considerations in treatment planning, such as selection of the restorative material, biomechanical design, color selection, dental substrates conditioning and adhesive cementation. This article discusses a brief review on the topic and a case presentation in which a posterior tooth was rehabilitated with an IPS Empress Esthetic® ceramic onlay.
