STATEMENT OF PROBLEM Three main factors which determine the success of an All-ceramic restoration are esthetic value, resistance to fracture and third being the marginal fit. Marginal fit and internal adaptation are crucial factors in increasing the longevity of the restoration. Newer and economical CAD CAM systems have been introduced claiming better marginal fit and adaptation of All ceramic ...

This study evaluated the accuracy of marginal and internal fit between the all-ceramic crowns manufactured by a conventional double-layer computer-aided design/computer-aided manufacturing (CAD/CAM) system and a single-layer system. Ten standardized crowns were fabricated from each of these two systems: conventional double-layer CAD/CAM system (Procera) and a single-layer system (Cerec 3D). The...

BACKGROUND Different CAD/CAM machines' generation may impact the restoration overall quality. The present study evaluated the marginal fit of CAD/CAM restorations manufactured with different generations of CEREC milling unit systems. MATERIAL AND METHODS Sixteen typodont teeth were divided into two groups (n=8) according to the machine's generation assigned. These are control group (G1): Cere...

The purpose of this in vitro study was to evaluate marginal and internal fits ceramic crowns fabricated with chairside computer-aided design manufacturing (CAD/CAM) systems. An experimental model based on ISO 12836:2015 digitally scanned different intraoral scanners (Omnicam (CEREC), EZIS PO (DDS), CS3500 (Carestream)). Ceramic were using the CAD/CAM process recommended by each system (CEREC, E...

Objective: The objective of this in vitro study was to evaluate the volumetric wear three CAD/CAM (computer-aided design/computer-aided manufacturing) ceramic materials. Materials and Methods: materials evaluated were CEREC Blocs (Dentsply Sirona), Initial LRF (GC) Amber Mill (HASS Corp). All samples (n=30) subjected simulated brushing (100,000 cycles). assessed by superimposing pre- post-brush...

OBJECTIVES CAD-CAM system is popular because of high esthetic and short fabrication time. But, there is limited information available about the microtensile bonding of luting cements to CAD-CAM inlays and to dentin. The aim of this study was to examine the bond strength of CAD-CAM (Cerec 3) and pressed-ceramic (IPS Empress 2) inlays to dentin surface by microtensile testing using two luting cem...

This paper describes treatment planning and dental rehabilitation of permanent maxillary incisors of an 11-year old patient affected by hypoplastic Amelogenesis imperfecta using CEREC chair side technology. The treatment was conducted in a multidisciplinary approach and followed by orthodontic treatment using self-ligating brackets to achieve optimum results. The teeth were treated endodontical...
