1. Printing 3D models of canine jaw fractures for teaching undergraduate veterinary medicine
Abstract Purpose To develop 3D anatomical models, and corresponding radiographs, of canine jaw fractures. Methods A base model was generated from a mandibular bone scan. With this model it was possible to perform fracture planning according to the anatomical location. Results The 3D base model of the canine mandible was similar in conformation to the n

2. Restorative Possibilities Using Zirconia Ceramics for Single Crowns
Resumo Dois casos clínicos são apresentados para explorar as diferenças técnicas e discutir as vantagens e desvantagens de se utilizar zircônia com cerâmica estratificada ou monolítica para confeccionar coroas unitárias. O primeiro caso descreve os passos clínicos na confecção de uma coroa monolítica no segundo pré-molar esquerdo utilizando uma

3. Diagnosis and management of eosinophilic granuloma of the jaw: a case report
RESUMO O granuloma eosinofílico é a forma mais comum da Histiocitose das células de Langerhans e que na maioria das vezes é representada por uma lesão osteolítica unilocular podendo acometer crianças e adultos. Trata-se de uma lesão óssea destrutiva caracterizada por presença de um vasto número de eosinófilos e histiócitos, podendo ser localizad

4. Fatigue survival and damage modes of lithium disilicate and resin nanoceramic crowns
Abstract Polymer-based composite materials have been proposed as an alternative for single unit restorations, due to their resilient and shock absorbing behavior, in contrast to the brittleness of ceramic materials that could result in failure by fracture. Objective: To evaluate the fatigue strength and damage modes of monolithic posterior resin nanoceramic

5. Failure Probability, Stress Distribution and Fracture Analysis of Experimental Screw for Micro Conical Abutment
Resumo O objetivo deste estudo foi avaliar a probabilidade de falha de dois tipos de parafusos para pilar protético após a compressão e analisar a distribuição da tensão com o método dos elementos finitos. Sessenta (60) restaurações unitárias foram montadas em implantes de titânio (e-fix, A.S. Technology - Titanium Fix). Os grupos foram divididos

6. Tooth whitening affects bond strength of adhesive systems in enamel
ABSTRACT This study presents how the tooth whitening affects the bond strength and fracture type of three distinct adhesives — a conventional, a self-etching, and a universal adhesive — in enamel. Health bovine incisors were prepared by flattening the labial surface; part of these teeth was submitted to whitening treatment with a peroxide-based product (

7. Finite element simulation of fracture in a restored premolar tooth using high aspect ratio elements
Abstract Introduction The term cracked tooth syndrome refers to an incomplete fracture of a vital posterior tooth that involves the dentin and occasionally extends into the pulp. There is a very limited number of publications trying to model dentin crack growth using numerical techniques. Therefore, it is essential to numerically model this phenomenon in o

8. Should my composite restorations last forever? Why are they failing?
Abstract Composites resins have become the first choice for direct anterior and posterior restorations. The great popularity is related to their esthetic appearance and reduced need of sound tissue removal as compared with former treatments. Several studies have demonstrated that composite restorations may last long in clinical service. In this review we dis

9. Effect of different composite core materials on fracture resistance of endodontically treated teeth restored with FRC posts
Abstract Objective This study evaluated the fracture resistance of endodontically treated teeth restored with fiber reinforced composite posts, using three resin composite core build-up materials, (Clearfil Photo Core (CPC), MultiCore Flow (MCF), and LuxaCore Z-Dual (LCZ)), and a nanohybrid composite, (Tetric N-Ceram (TNC)). Material and Methods Forty en

10. Diagnosis of alveolar and root fractures: an in vitro study comparing CBCT imaging with periapical radiographs
Abstract Objective To compare periapical radiograph (PR) and cone-beam computed tomography (CBCT) in the diagnosis of alveolar and root fractures. Material and Methods Sixty incisor teeth (20 higid and 40 with root fracture) from dogs were inserted in 60 anterior alveolar sockets (40 higid and 20 with alveolar fracture) of 15 macerated canine maxillae.

11. Comparative in vitro evaluation of CAD/CAM vs conventional provisional crowns
ABSTRACT Objective This study compared the marginal gap, internal fit, fracture strength, and mode of fracture of CAD/CAM provisional crowns with that of direct provisional crowns. Material and Methods An upper right first premolar phantom tooth was prepared for full ceramic crown following tooth preparation guidelines. The materials tested were: VITA CA

12. Effects of alpha-tocopherol on fracture resistance after endodontic treatment, bleaching and restoration
Abstract This study evaluated the effects of 10% alphatocopherol on the fracture resistance of endodontically treated teeth subjected to tooth bleaching with hydrogen peroxide and immediately restored with composite resin. Fifty bovine incisors were selected, including 10 sound teeth that constituted the control group (G1 (C)). The remaining 40 teeth, which
