Objective To review materials available in computer‐aided design/computer‐aided manufacturing (CAD/CAM), their various properties and accuracy are compared to conventional materials/methods when available. Overview CAD/CAM in dentistry is constantly growing and becoming a user‐ and patient‐friendly technology and service using intraoral scanners and laboratory/chairside milling units to manufacture dental restorations and appliances from multiple materials including wax, metals, composite resins, and ceramics. Properties of these materials may vary when compared to restorations prepared from conventional and additive manufacturing methods. Understanding the differences in these properties is important for material and fabrication method selection. Additive manufacturing is becoming an alternative to subtractive manufacturing in many applications. However, chemical composition, mechanical and physical properties of these materials are still lacking. 3D printed materials require a considerable amount of research and time to prove their clinical efficacy. Conclusion The current developments in, and possibilities of, CAD/CAM technology is exciting and is transforming restorative dentistry. With all this excitement, it is crucially important to ensure that proper testing and evaluation of the various materials are warranted before making definite claims and decisions to replace conventionally prepared materials. Clinical Significance CAD/CAM materials are versatile and emerging as the material of choice for many restorations and appliances. For recently introduced CAD/CAM materials, it is important to ensure that proper clinical‐ and research‐based evidence confirming the success and durability of these materials are available before recommending them in patient care.

“…Air-abrasion, by means of aluminum oxide particles of the zirconia intaglio surface is the most acceptable mechanical treatment since it cleans the surface and makes it a more reactive surface (microretentions and higher surface free energy), and it increases the surface area available for bonding (30,31) . In addition, the damaging effect of air-abrasion particles on the mechanical behavior of Y-TZP materials has been reported, that researchers have recommended that the zirconia ceramic should be air-abraded at low pressure with small particle sizes of aluminum oxide (32) .…”

Objective: This study evaluated the effect of preparation designs and surface treatment on the fracture resistance of zirconia inlay retained fixed dental prosthesis (IR-FDPs). Material and Methods: Twenty secondary premolars and twenty secondary molars were used in this study. Twenty zirconia IR-FDPs were constructed, divided into two main groups, ten specimens each, according to abutment preparation (box & tube shape), each main group was subdivided into two sub groups according to surface treatment (Air abrasion & MDP primer surface treatment). The IR-FDPs were cemented using dual cure resin cement, then the specimens were subjected to thermo-mechanical cyclic loading (TMCL). The fracture resistance was measured. Results: The results showed that there was no statistically significant difference between air abrasion and MDP for both designs (box & tube shape).The effect of design showed that there was statistically significant difference for both surface treatments between tube and box design where box design showed higher fracture resistance than tube design for both surface treatments. Conclusion: Inlay retained fixed dental prosthesis (IR-FDPs) with box shape provide more fracture resistance than with tube shape. The air abrasion surface treatment shows similar fracture as the MDP primer surface treatment.

“…If air borne-particle abrasion is chosen as the surface pretreatment for resin ceramics, grit blasting should be performed with due care. The use of small particles and low pressures is of particular importance, because otherwise surface damage and crack formation may occur (21) .…”

Objective: The objective of this study was intended for evaluation the effect of different surface treatments on microhardness and flexural strength of two types of resin ceramics. Materials and Methods: A total number of 140 samples were used in this study (70 samples for each test). This samples were divided into two equal groups according to materials (Vita Enamic [ENA] and Lava Ultimate [LVU]), then each group was subdivided according surface treatments into five subgroups Gr 1; no surface treatment (control), Gr 2; alumina particles with size (50µm) for sandblasting, Gr 3; alumina particles with size (110µm) for sandblasting, Gr 4; etching by plasma technology, Gr 5; etching by hydrofluoric acid (n=7). Microhardness was measured by using Digital Display Vickers Microhardness Tester and flexure strength by using Universal Testing Machine. Results: The results of this study revealed that; Control group of ENA recorded statistically significant highest microhardness. Control group of LVU recorded statistically significant highest flexure strength. Conclusion: Surface treatment has adverse effect on microhardness and flexure strength of both resin ceramic materials.
