background: this in vitro study investigated the marginal fit of two porcelain laminate veneers to help the selection of more accurate veneers in discolored teeth. materials and methods: thirty impressions of metal master die created from the prepared labial surface of an acrylic maxillary central incisor were made and poured with type iv stone. the dies were distributed into test groups (n = 1...

STATEMENT OF PROBLEM The erbium, chromium: yttrium, scandium, gallium, garnet (Er,Cr:YSGG) hydrokinetic laser system has been successful in the ablation of dental tissues. It has been reported that this system is also useful for preparing tooth surfaces for adhesion, but results to date have been controversial. PURPOSE This in vitro study evaluated the bond strengths of porcelain laminate ven...

When dentists are considering restoration of maxillary anterior teeth to improve esthetics, they must often choose between porcelain veneers and full-coverage crowns. Porcelain veneers are considered much more conservative in terms of the requirements for preparation, and they provide satisfactory, long-lasting esthetic results. Typically only the facial surface is involved in veneer preparatio...

In this study, the dimensional stability and mechanical properties of plywood made from untreated plasma-pretreated beech veneers were compared. The wood used (native thermally modified) impregnated with melamine resin in a simple dipping process prior to production. duration impregnation was adjusted give same loading for different veneer types, requiring only fraction time compared non-plasma...

PURPOSE This systematic review reports on the survival of feldspathic porcelain veneers. MATERIALS AND METHODS The Cochrane Library, MEDLINE (OVID), Embase, Web of Knowledge, selected journals, clinical trials registers, and conference proceedings were searched independently by two reviewers. Academic colleagues were also contacted to identify relevant research. Inclusion criteria were human ...

Crown fractures are common among schoolchildren. They create serious functional, aesthetic and psychological problems. The clinicians must propose high aesthetics in the front part and the choice of exact treatment plan. Repeated reconstructions are needed in many cases because of compromised results as time passed by. Achievement of promising restoration that preserves its aesthetics and stren...

OBJECTIVE The objective of this study was to evaluate the clinical results of 323 porcelain laminate veneers over a period of 3 to 11 years. MATERIAL AND METHOD This study included 70 patients, aged between 18 and 74 years. Of the 323 total veneers, 124 were of a simple design and 199 were of a functional design. The condition of the soft tissues and hygiene, in addition to the condition of t...

PURPOSE The purpose of this study was to evaluate whether surface treatments affect the translucency of laminate veneers with different shades and thicknesses. MATERIALS AND METHODS A total of 224 disc-shaped ceramic veneers were prepared from A1, A3, HT (High Translucent) and HO (High Opaque) shades of IPS e.max Press (Ivoclar Vivadent) with 0.5 mm and 1.0 mm thicknesses. The ceramics were d...

No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthet...

This article describes treatment of a young adult patient with porcelain laminate veneers for restoring unaesthetic maxillary anterior teeth with two retained primary canines. The patient had experienced an approximately two-year orthodontic treatment and had received both fixed and removable retainers for the upper arch. The patient could not afford implant supported restorations for his missi...
