2. Recovering Streptococcus mutans over restorations by the tray technique: a randomized clinical study
AIM: To correlate the tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. METHODS: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner' Cohen-Kappa

3. Influence of elastic recovery time on the Dimensional Stability of Polydimethylsiloxane (PDS)
The aim of this study was to determine the influence from the recovering time on the dimensional stability of polydimethylsiloxane (Speedex, Coltène/Whaledent Company, Altstätten, Switzerland) prior to type IV dental stone pouring. The double impression technique was utilized with uniform spacing of 1 mm for the wash paste, at 30 minutes, 24 hours and 72 h

4. Influence of the casting material on the dimensional accuracy of dental dies
The purpose of this study was to evaluate the dimensional accuracy of different materials used in the confection of dies. Two stainless steel standard models were confected. One of the models, which was 2 mm larger than the other model, was used to provide a uniform relief for the two-step putty-wash impression technique. Thirty impressions were obtained usi

5. Evaluation of the accuracy of different transfer impression techniques for multiple implants
The aim of this study was to evaluate the accuracy of three implant transfer impression techniques. Four groups (n = 5) were defined, according to the technique: TC - tapered copings without splint; SC - square copings without splint; SCS - square copings splinted with dental floss and acrylic resin, and CG (control group) - master model with four external h

6. Avaliação in vitro de materiais e técnicas de transferência em implantes múltiplos / In vitro evaluation of materials and tranfer techniques in multiple implants
Objectives: The aim of this study is to compare different materials and techniques used in multiple implant transfer impressions, measuring the gap between superstructure and the implants. Method: Four external hexagonal implants (Neodent, Curitiba, Brazil) were fixed in a master cast and over a superstrucure. Afterwards, the impressions were made using poly

7. Linear dimensional changes in plaster die models using different elastomeric materials
Dental impression is an important step in the preparation of prostheses since it provides the reproduction of anatomic and surface details of teeth and adjacent structures. The objective of this study was to evaluate the linear dimensional alterations in gypsum dies obtained with different elastomeric materials, using a resin coping impression technique with

8. Accuracy of stone casts obtained by different impression materials
Several impression materials are available in the Brazilian marketplace to be used in oral rehabilitation. The aim of this study was to compare the accuracy of different impression materials used for fixed partial dentures following the manufacturers' instructions. A master model representing a partially edentulous mandibular right hemi-arch segment whose te

9. Determinação das forças geradas por resinas acrílicas ativadas quimicamente durante o processo de transferência da posição de implantes Análise fotoelástica
The great number of laboratorial phases during implant-supported prostheses may contribute to deficient passivity fit. This misalignment could lead to screws relieves and also, the loss of osseointegration. Impression technique is an important step to be observed. Many materials and techniques are involved in this stage and acrylic resin is the most frequent

10. In vitro evaluation of the precision of working casts for implant-supported restoration with multiple abutments
OBJECTIVE: The purpose of this study was to compare the accuracy of two working cast fabrication techniques using strain-gauge analysis. METHODS: Two working cast fabrication methods were evaluated. Based on a master model, 20 working casts were fabricated by means of an indirect impression technique using polyether after splinting the square transfer coping

11. "IN VITRO" EVALUATION BETWEEN DIFFERENT UNION METHODS OF MOLDING COPINGS USED IN THE IMPLANT DENTISTRY / AVALIAÇÃO IN VITRO ENTRE DIFERENTES MÉTODOS DE UNIÃO DE TRANSFERENTES DE MOLDAGEM UTILIZADOS NA IMPLANTODONTIA
O propósito desta pesquisa foi avaliar comparativamente 2 técnicas de moldagem utilizadas em prótese sobre implantes, variando os métodos de união entre os transferentes. A partir de uma matriz metálica contendo três análogos de implantes foi fabricada uma barra metálica pelo método de soldagem a laser. Em seguida foram confeccionadas 20 moldeiras
