The aim of the study was to compare hardness, coefficient friction, and wear experienced by four different ceramic samples: 3Y-TZP zirconium oxide ceramics—Zi—Ceramill Zi (Amman Girrbach), 5Y-PSZ transparent ceramics—Zol—Ceramill Zolid Sak—feldspathic ceramics—Sakura Interaction (Elephant), Glaze Girrbach). Vickers hardness samples measured. Friction tests ball-on-disc were performed between discs ceramics a zirconia ball, then premolar tooth as counter-sample. mass loss friction...

Pathological tooth wear is an escalating social problem. Occlusal veneers can be alternative to traditional prosthetic restorations such as crowns, inlays, and onlays. Background: The aim of this study assess the fracture resistance occlusal made various materials depending on their thickness. Methods: In total, 120 were examined. four ceramics: leucite LC (IPS Empress Esthetic), hybrid HC (Vita Enamic), lithium disilicate LDC e.max Press), zirconium oxide ZOC (Ceramill Zolid HT). A total 30...

Fixed restorations are now among the most common in modern dental prosthodontics. The current view prosthodontics of maximum preparation economy is causing an increased interest mechanical properties cements. Among important materials used for indirect cementation properties, i.e., hardness and compressive strength. These can change as a result changes physical factors. purpose this study was to analyze available literature on effect conditioning temperature cements fixed durability their...

Resin cements establish a strong durable bond between zirconia ceramic and hard tissues of teeth. It is essential to use primers with proper chemical composition before cementation.The aim this study was assess the influence primer's on shear strength resin cements.132 specimens were randomly assigned four groups. There systems used. They included cement respective primer, dedicated zirconia: Clearfil Ceramic Primer/Panavia F2.0, Monobond Plus/Multilink Automix, AZ - Primer/ResiCem, Z Prime...

Introduction. Prosthetic restorations should be adjusted to the patients’ occlusion and articulation. Traditional modern articulator face-bow systems that simulate individual jaw movements are used in treatment. Aim of study. The aim study was compare values TMJ angles based on ARCUSdigma examination wax records Protar 7 articulator. Method. conducted a group 20 patients aged 23-30 years with full dentition normal occlusion. position maxilla recorded ARCUSevo. Every patient examined using II...

During mastication, molars are subjected to heavy stress. However, a full explanation of the effects physiological loads on tooth structures is lacking.The study aimed determine stress in and identify mechanism enamel damage grooves teeth during computer-simulated mastication.The was carried out using finite element method (FEM). A three-dimensional (3D) model first mandibular molar crown opposing maxillary created. food bite introduced between antagonistic teeth. The mastication cycle bolus...
