AIM The aim of this report is to present five-year follow-ups of two different applications for the use of direct laminate resin-based composite veneers to improve esthetics. BACKGROUND Defects in the maxillary anterior teeth, such as enamel hypoplasia and peg lateral, can present esthetic challenges. Furthermore, a treatment plan that can be completed in a single appointment is highly desira...

UNLABELLED In case of severe dental erosion, the maxillary anterior teeth are often particularly affected. Restoring such teeth conventionally (ie, crowns) would frequently involve elective endodontic therapy and major additional loss of tooth structure. A novel, minimally invasive approach to restore eroded teeth has been developed and is currently being tested in the form of a prospective cli...

Technological advances in materials and techniques have been allowing to obtain natural esthetic results with conservative interventions. Ceramic veneers are very effective tools for both esthetic and functional rehabilitation. Laminate veneers are a conservative treatment of unesthetic anterior teeth. This evolution of materials, ceramics, and adhesive systems permits improvement of the esthet...

1. We determined the effects of nutrient enrichment on wood decomposition rates and microbial activity during a 3-year study in two headwater streams at Coweeta Hydrologic Laboratory, NC, U.S.A. After a 1-year pretreatment period, one of the streams was continuously enriched with inorganic nutrients (nitrogen and phosphorus) for 2 years while the other stream served as a reference. We determine...

Bleaching is a common modification method widely used in the industrialization of wood dyeing. can regulate color wood, and it also has great effects on subsequent dyeing properties. In this work, three woods, Ayous, Linden, Poplar, were processed by using NaOH/H2O2/Na2SiO3 bleach pretreatment method. Then, pretreated untreated stained separately means water bath with dyestuffs: blue anthraquin...

This article describes esthetic improvement in a patient with a missing maxillary left central incisor. Space analysis of the anterior dentition showed that minor tooth rearrangement was needed. Optimal space distribution for restorations was attained by orthodontic treatment. Through transforming tooth shape with porcelain laminate veneers, the maxillary left lateral incisor was transformed in...

AIM To achieve satisfactory aesthetic appearance of ceramic veneers food debris retention and plaque formation, resulting in possible irritation of surrounding tissues, should be avoided. It is, therefore, necessary to decrease the roughness of ceramic surfaces as much as possible. The aim of this study was to evaluate surface roughness of ceramic veneers after polishin15038787 g with four diff...

To evaluate stress distribution when applying vertical and tangential forces to 1mm thick occlusal veneers with different finish lines preparations, using the finite element method. One extracted third molar was prepared for veneers, firstly without any bevel. It scanned in order design two groups of lithium disilicate (G1A, G2A) composite resin (G1B, G2B) veneers. Then, preparation modified, b...
