Y-TZP–based infrastructures for crowns and FPDs present favorable physical, mechanical, and optical properties. Some Y-TZP–based restorative systems use CAD/CAM technology. Nevertheless, technicians should be able to employ traditiona...

The aim of this randomized controlled clinical trial was to compare the early clinical outcome of slip-cast glass-infiltrated Alumina/Zirconia and CAD/CAM Zirconia all-ceramic crowns. A total of 30 InCeram Zirconia and Cercon Zirconia crowns were fabricated and cemented with a glass ionomer cement in 20 patients. At baseline, 6-month, 1-year, and 2-year recall appointments, Californian Dental A...

QDT 2005 1 he restoration of missing or compromised tooth structure requires dental materials that offer toothlike esthetics, functionality, biocompatibility, and longevity. Silica-based ceramics (eg, feldspathic porcelain) offer all of these necessities and are the materials of choice for esthetic all-ceramic restorations (eg, laminate veneers, ceramic inlays and onlays, and full-coverage jack...

statement of the problem: although all-ceramic restorations are broadly used, there is a lack of information concerning how their fit is affected by fabrication procedure and marginal configuration. purpose: the purpose of this study was to evaluate the marginal fit of zirconia cad/cam ceramic crowns before and after porcelain firing. the influence of finish line configuration on the marginal f...

Background: Few studies have assessed the survival of restorations and particularly zirconia based crowns in the restoration of the severely worn dentition. This study aimed to determine survival and factors associated with failure in anterior teeth worn through to dentine restored with LavaTM crowns. Methods: A convenience sample of 30 participants (27 male, 3 female) had 161 LavaTM crowns pla...

Objective: The main aim of this study was to compare fracture load and fracture mode of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) and metal-ceramic (MC) molar crowns using a modified test set-up to produce fractures similar to those seen in vivo, i.e. fractures of the veneering material rather than complete fractures. Materials and methods: 13 high-noble-alloy MC and 13 Y-TZP mo...

PURPOSE This study compared the influence of two luting cements on the clinical performance of single crowns. MATERIALS AND METHODS Twenty patients received 39 pairs of metal-ceramic and Procera crowns cemented with zinc phosphate and resin-modified glass-ionomer luting cement (Vitremer) in a split-mouth randomized pattern blinded to the recipient. The crowns were examined immediately after c...

The study was designed to survey the curricular requirements, types of clinical experience, and materiak/ techniques used in teaching programs for all-ceramic restorations in Scandinavian dental schools. All 13 dental schools responded. Ten offered some clinical experience to pre-doctoral students, but only onc required one all-ceramic restoration. The departments of futed prosthodontics had th...

OBJECTIVES The objective of this systematic review was to assess the 5-year survival rates and incidences of complications associated with ceramic abutments and to compare them with those of metal abutments. METHODS An electronic Medline search complemented by manual searching was conducted to identify randomized-controlled clinical trials, and prospective and retrospective studies providing ...
