In all-ceramic restorations, crack formation and propagation phenomena are of major concern, since they may result in intra-oral fracture. The objective of this study was calculation of damage in porcelain MOD inlays by utilization of a finite-element (FE) implementation of the distributed crack theory. "Damage" is defined as the parameter that describes the local decrease of stiffness caused b...

OBJECTIVE The aim of this study was to assess the resistance of fracture of mesio-occlusal-distal (MOD) ceramic inlays and composite fillings in premolars and to compare fracture modes between the groups. MATERIAL AND METHODS Twenty seven extracted intact human premolars were selected and divided into three groups: I - intact teeth (control group), II - MOD cavities restored with indirect cer...

OBJECTIVE The aim of this study was to investigate the in-vitro marginal adaptation of all-ceramic class II inlays which were luted with conventional multi-stage pre-treatment cements and one new type of cement, which requires no conditioning. METHODS The marginal adaptation of 56 all-ceramic inlays was determined with scanning electron microscopy and microleakage tests. The marginal integrit...

AIM This in vitro study compares a new system for manual chair side fabrication of indirect composite restorations, which uses silicone models after alginate impressions, to CAD/CAM-technology and laboratory manual production techniques. MATRIALS AND METHODS: and study design Each 10 composite inlays were fabricated using different types of production techniques: CAD/CAM- technology (A), the ne...

Abstract Nine unpublished obsidian artefacts (one cosmetics jar, two vessel fragments, and six eye inlays) from the Garstang Museum collection are presented, with aim of patching gaps in current record concerning their excavation contexts material properties, which were presumably detailed John Garstang’s now-lost report/notes. The objects date to Early Dynastic Old Kingdom periods, five matche...

To investigate the bonding of tooth-colored indirect restorations to cervical dentin, shear bond strengths of bonded resin inlays to cervical dentin and mid-coronal dentin were investigated and compared. Indirectly fabricated composite inlays (Estenia) were cemented with a dual-cured resin cement (Panavia Fluoro Cement II) to either cervical or mid-coronal dentin. Resin cement was cured with or...

OBJECTIVE The aim of the present study was to clinically evaluate the effect of two different adhesive/resin composite combinations for luting of IPS Empress inlays. METHODS Ninety-four IPS Empress restorations were placed in 31 patients in a controlled prospective clinical split-mouth study. The restorations were luted with EBS Multi/Compolute (3M Espe) or with Syntac/Variolink II low (Ivocl...

OBJECTIVE To report epithelial perilenticular opacity as a new complication of intracorneal inlay implantation for the correction of hyperopia. DESIGN Prospective observational case series. PARTICIPANTS Eleven eyes of 7 patients underwent intracorneal inlay implantation for the correction of hyperopia. METHODS Intracorneal inlays were implanted onto the stromal bed by using a microkeratom...
