Introduction: This in vitro study investigates the marginal and internal fit of indirect class II composite restorations. Two different processes for chair-side restorations were compared. In group A, the restorations were fabricated using CAD/CAM technology (Cerec, Sirona, Germany, Bernsheim) and in group B they were made by hand (GrandioSO Inlay System, VOCO GmbH, Germany, Cuxhaven). Methods:...

A method of tube joining by plastic deformation has efficient, reliable and environmentally friendly features, so that it is widely applied into the fabrication aviation pipeline. Internal rolling potential to join high strength titanium alloy tubes withstanding pressure medium with better sealing performance. Taking TA18 as case material, this presentation combines numerical modelling experime...

PURPOSE The purpose of this study was to evaluate the mechanical performance of different suture locking mechanisms including: i) interference fit between the anchor and the bone (eg, 4.5 mm PushLock, 5.5 mm SwiveLock), ii) internal locking mechanism within the anchor itself (eg, 5.5 mm SpeedScrew), or iii) a combination of interference fit and internal locking (eg, 4.5 mm MultiFIX P, 5.5 mm Mu...

to be able to compete effectively in the emerging learning environment, it is necessary that all nations continually enhance the ict use in universities. but, successful use of ict needs operational policies and programs that fit with the internal situations of countries. in this paper, by benchmarking 12 countries and 5 regions, 279 recommendations for enhancing the ict use in universities are...

Aim To evaluate the influence of different manufacturing methods of single implant-supported metallic crowns on the internal and external marginal fit through computed microtomography. Methods Forty external hexagon implants were divided into 4 groups (n = 8), according to the manufacturing method: GC, conventional casting; GI, induction casting; GP, plasma casting; and GCAD, CAD/CAM machinin...

BACKGROUND AND AIMS CAD/CAM systems facilitate the use of zirconia substructure materials for all-ceramic copings. This in vitro study investigated the marginal and internal fit of zirconia copings made with CAD/CAM system and slip-casting method. MATERIALS AND METHODS Sixteen CAD/CAM made zirconia copings and 16 slip-cast made zirconia copings were fabri-cated and cemented with glass-ionomer...
