In this study, two types of porous zirconia and dense zirconia were used. The flexural strength of non-layered zirconia specimens and those of the layered zirconia specimens with veneering porcelain were examined. Furthermore, the shear bond strength of veneering porcelain to zirconia was examined. The flexural strength of the non-layered specimens was 1,220 MPa for dense zirconia and 220 to 30...

Aim: The aim of this study was to determine the effect of different luting cements and accelerated artificial aging (AAA) in the fracture resistance of porcelain laminate veneers (PLVs). Materials and methods: A total of 80 disc-shaped specimens were prepared using computer-aided design/computer-aided milling technology from lithium disilicate glass-ceramic blocks. Specimens (0.5 mm thick, 10 m...

One of the reconstructive choices for the completely edentulous patient is the placement of multiple implants and the fabrication of a fixed implant-supported complete denture. These patients experience an improvement in masticatory performance over patients who wear complete dentures. The fixed-implant complete denture consists of a metal bar with acrylic resin and denture teeth connected to i...

Plasma and halogen lamp units were used to photo-cure a composite resin for porcelain bonding. Mean shear bond strengths to dentin after light curing through porcelain of 1 and 2 mm thickness ranged from 20 to 27 MPa before and after thermocycling, indicating no significant effects due to porcelain thickness, curing method, or thermocycling, except for plasma curing for 3 s through porcelain of...

A 51-year-old woman who worked as a company sales representative was concerned about the deteriorating condition of her anterior teeth. On presentation, the appearance of her anterior teeth was less than ideal, and she requested treatment to improve the situation. Her medical history was noncontributory, but intraoral examination revealed excessive diastema between the maxillary central incisor...

Materials and Methods: Patients for the prospective long-term case cohort study were recruited for a complete clinical and radiographic examination at 1 and 10 year intervals after implant placement. The sample size of this study was 89 patients with an age range of 28-88 years. The treatment plans for implant restoration utilized 3 restorative treatment plans: single crowns (SC); implant-impla...

This investigation examined the marginal characteristics of the collarless metal ceramic restoration made with two commonly used direct-lift techniques: (1) a porcelain/wax paste and (2) a porcelain/liquid slurry. The metal copings touched the shoulder in half of the groups and were left 0.5 mm short in the other half to comprise the four experimental groups. Marginal seal was evaluated at faci...

PURPOSE This study evaluated the bond strength between porcelain denture teeth (Bioblend 43D) and four different polymerized denture resins (Lucitone 199, Palapress, Acron MC, Triad) with and without a bonding agent and after four different types of surface treatment (polished, HF etched, sandblasted, air-abraded). MATERIALS AND METHODS Central incisor porcelain denture teeth were divided int...

Objectives: Porcelain veneers are steadily increasing in popularity among today’s dental practitioners for conservative restoration of unaesthetic anterior teeth. As with any new procedure, in vitro and in vivo investigations are required to assess the ultimate clinical efficacy of these restorations. The current literature was therefore reviewed in search for the most important parameters dete...
