1. Clinical performance and failure modes of pulpless teeth restored with posts: a systematic review
Abstract The aim of this systematic review was to compare the clinical performance and failure modes of teeth restored with intra-radicular retainers. A search was performed on PubMed/Medline, Central and ClinicalTrials databases for randomized clinical trials comparing clinical behavior and failures of at least two types of retainers. From 341 detected pape

2. In vitro evaluation of the marginal and internal discrepancies of different esthetic restorations
Objective: This study examined the fit of two types of all-ceramic single crowns and indirect composite resin full coverage crowns. Material and Methods: Thirty intact human mandibular first premolars were selected for this study and prepared using a machine to standardize the dimensions and randomly divided into 3 groups. Slip cast (IC) (In-Ceram Zirc

3. Wear of double crown systems: electroplated vs. casted female part
OBJECTIVES: The wear of telescopic crowns is a common problem often reducing the patient's satisfaction with the denture and resulting in a renewal of the denture. The study aims to compare the wear behavior of conical crowns using electroplated copings (group E ) with standard telescopic crowns with cast female parts (group C). MATERIAL AND METHODS: 10 coni

4. Estudo dos fatores interferentes na adaptação marginal de próteses confeccionadas em titânio comercialmente puro e ligas alternativas / Study of determining factors for the marginal fit of prosthesis made of commercially pure titanium and alternative alloys
O desajuste de copings obtidos por fundição por cera perdida está sujeita à vários fatores tais como: contração de fundição do metal, expansão do revestimento, uso de espaçadores, entre outros. O objetivo do estudo foi avaliar o desajuste marginal pré e pós cimentação de copings obtidos com três ligas de metais básicos - Ni-Cr-Be (VB), Ni-Cr

5. Influence of marginal fit and cement types on microleakage of all-ceramic crown systems
The purpose of this study was to evaluate the effects of both marginal fit and cementing with different luting agents on the microleakage of all-ceramic crown systems. Thirty-six extracted upper central incisors were prepared for full-coverage crowns and were divided into three groups. Group 1: CAD/CAM-fabricated ZrO2, Group 2: Heat-pressed lithium-disilicat

6. Stress prediction in a central incisor with intra-radicular restorations
A 2D finite element analysis was applied to calculate shear and von Mises equivalent stresses developed, under masticatory loading, in an upper central incisor restored with cast gold post and carbon fiber reinforced epoxy resin post. Based on the predicted shear stress levels, it is concluded that the gold post model is more prone to shear failure along the

7. Effect of phosphate-bonded investments on titanium reaction layer and crown fit
This study analyzed the reaction layer and measured the marginal crown fit of cast titanium applied to different phosphate-bonded investments, prepared under the following conditions (liquid concentration/casting temperature): Rema Exakt (RE) - 100%/237°C, 75%/287°C, Castorit Super C (CS)-100%/70°C, 75%/141°C and Rematitan Plus (RP)- 100%/430°C (special

8. Retenção de grampos cirucenferenciais associados a retentores intra-radiculares com encaixe era utilizados em overdentures parciais removíveis / Retention clips cirucenferenciais associated with CuAlZn with docking was used in removable partial overdentures
The overdentures can be defined as total or partial removable dentures that cover root or osseo integrated implants rehabilitating the whole dentition. The mechanical retention in the removable partial overdentures (RPOs) is obtained through the use of cast clasps and attachments. This biomechanical principle has a great importance, since is inwardly associa

9. Efeito da altura do remanescente coronário, do tipo de reconstrução interna e do tipo de coroa restauradora na deformação e resistência à fratura de dentes anteriores tratados endodonticamente
The endodontically treated teeth restoration is important aspect in dental practice and involves many treatment options with varying complexity. The aim of this study was to evaluate the strain, fracture resistance and failure mode of endodontically treated teeth depending of the post and core type, the ferrule presence, restored with metallic or ceramics re

10. Evaluation of the use of die spacer over the marginal fit of casting copings of Ni-Cr, Ni-Cr-Be and commercially pure Titanium / Avaliação da adaptação marginal de copings metálicos fundidos em ligas de níquel-cromo, níquel-cromo-berílio e em titânio comercialmente puro em função da aplicação de espaçadores
The purpose of the study was to evaluate the effect of using die spacers on the marginal fit of Ni Cr (Verabond II) (VB II) and Ni-Cr-Be (Verabond) (VB) alloys and commercially pure Titanium (Tritan) (Ti-cp) casting copings by the lost wax technique. Using a metal master die, 135 Resin Added Extra Hard Type IV Stone were obtained for the fabrication of wax p

11. Internal adaptation of cast titanium crowns
As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were

12. Análise da técnica de fundição rápida segundo a adaptação cervical de infra-estrutura de liga à base de Ni-Cr e expansões de presa e térmica de quatro revestimentos / Analysis of accelerated casting technique in accordance with marginal adaptation of Ni-Cr crown and curing expansion and thermal expansion of four investments
With the improvement of dental investments for accelerated casting technique, recent studies have demonstrated that the procedure can be considered safe for daily use in the dental laboratory. Thus, cast pieces can be obtained in less time, the prosthetic work as a whole can be speed up and costs are cut with no quality compromise. Even though, there are sti
