OBJECTIVES This investigation describes a rapid method for the generation of finite element models of dental structures and restorations. METHODS An intact mandibular molar was digitized with a micro-CT scanner. Surface contours of enamel and dentin were fitted following tooth segmentation based on pixel density using an interactive medical image control system. Stereolithography (STL) files ...

Metallic materials have widespread use in dentistry for clinical treatment and restoration of teeth. Major areas of usage are: (1) restorative dentistry and prosthodontics (dental amalgam and gold alloy restorations for single teeth, metallic restorations for multiple teeth, including metal-ceramic restorations, removable partial denture frameworks, and dental implants), (2) orthodontics (wires...

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...

Objectives To present the treatment approach for restoration of localised anterior erosive wear using a combination dental materials. Clinical considerations A patient presented in private practice concerned about aesthetics his teeth. The patient's history and clinical examination revealed on labial palatal aspects maxillary central incisors right lateral incisor. formulated plan was to restor...

In polycrystalline metals, local deformation heterogeneities induced by the microstructure influence fatigue crack initiation and micro-crack propagation. The localization in plastic strains associated with heterogeneous deformation has been described as a necessary condition and a precursor for the nucleation of fatigue cracks. However, a clear and quantitative assessment of the correlation be...

This report describes the bonding technique and clinical course of porcelain laminate veneer restorations applied to discolored maxillary incisors and canines. The patient was an 18-year-old woman, and tooth reduction was limited to the enamel. Laminate veneer restorations were made with a feldspathic porcelain material (Cosmotech Porcelain). After try-in, enamel surfaces were etched with 65% p...

QDT 2013 Over the last decade, laboratory procedures have changed dramatically due to the introduction of computer-aided design/computerassisted manufacture (CAD/CAM) technology. This evo lu tion began with the use of zirconia as a base material for dental restorations. Recently, the use of CAD/CAM-fabricated full-contour zirconia (FCZ) crowns for posterior teeth has become a popular restoratio...

ABSTRACT Digital smile design is an important tool for esthetic planning in dentistry as it facilitates ease of communication between professionals and patients. This clinical report has the objective describing a procedure involving digital placement porcelain laminate veneer restorations. The included dental facial analyzes. curve was drawn ruler used to delimitate spaces each tooth. An appro...

AIMS/BACKGROUND The objective of this review was to define the impact of cementation mode on the longevity of different types of single tooth restorations and fixed dental prostheses (FDP). METHODS Literature search by PubMed as the major database was used utilizing the terms namely, adhesive techniques, all-ceramic crowns, cast-metal, cement, cementation, ceramic inlays, gold inlays, metal-c...

This clinical report describes the fabrication and bonding of porcelain laminate veneer restorations in a patient with anterior open spaces. Laminate veneer restorations made of feldspathic porcelain were etched with 5% hydrofluoric acid, rinsed under tap water, ultrasonically cleaned with methanol, and primed with a chemically activated three-liquid silane bonding agent (Clearfil Porcelain Bon...
