1. 3D comparison of dental arch stability in patients with and without cleft lip and palate after orthodontic/rehabilitative treatment
Abstract This study aimed to compare the linear dimensions of the dental arches of adult patients with complete unilateral cleft lip and palate (UCLP) after orthodontic and prosthetic treatment with fixed partial dentures (FPD) to patients without clefts, using 3D technology. This retrospective longitudinal study sample consisted of 35 subjects divided into

2. Effect of cantilever length and alloy framework on the stress distribution in peri-implant area of cantilevered implant-supported fixed partial dentures
ABSTRACT Because many mechanical variables are present in the oral cavity, the proper load transfer between the prosthesis and the bone is important for treatment planning and for the longevity of the implant-supported fixed partial denture. Objectives To verify the stress generated on the peri-implant area of cantilevered implant-supported fixed partial d

3. Evaluation of the adaptation of zirconia-based fixed partial dentures using micro-CT technology
The objective of the study was to measure the marginal and internal fit of zirconia-based all-ceramic three-unit fixed partial dentures (FPDs) (Y-TZP - LAVA, 3M-ESPE), using a novel methodology based on micro-computed tomography (micro-CT) technology. Stainless steel models of prepared abutments were fabricated to design FPDs. Ten frameworks were produced wi

4. Analysis by the finite element method of the stress distribution in prosthetic components placed in implants with morse cone connection in the anterior maxilla / Análise pelo método dos elementos finitos da distribuição de tensões em componentes protéticos posicionados em implantes com conexão cone morse na região anterior da maxila
The aim of this study was to evaluate through the three-dimensional method of the finite elements the stress distribution in the bone / implant interface and implant / abutment on implants with morse cone connection, placed in the anterior maxilla. From a virtual reconstruction of bone from a CT scan, cantilever prosthesis (11-21) was simulated using prosthe

7. Biaxial flexural strength of Turkom-Cera core compared to two other all-ceramic systems
Advances in all-ceramic systems have established predictable means of providing metal-free aesthetic and biocompatible materials. These materials must have sufficient strength to be a practical treatment alternative for the fabrication of crowns and fixed partial dentures. OBJECTIVES: The aim of this study was to compare the biaxial flexural strength of thre

8. Fixed partial dentures in an up to 8-year follow-up
Information on the longevity of fiber-reinforced composite fixed partial dentures (inlay FPDs) should be considered in the selection of materials, operative techniques and patient instructions related to prognosis and long-term cost-effectiveness. OBJECTIVE: This study evaluated the long-term survival of fiber-reinforced, adhesively-bonded composite prosthes

9. Machined and plastic copings in three-element prostheses with different types of implantabutment joints: a strain gauge comparative analysis
OBJECTIVE: Using strain gauge (SG) analysis, the aim of this in vitro study was quantify the strain development during the fixation of three-unit screw implant-supported fixed partial dentures, varying the types of implant-abutment joints and the type of prosthetic coping. The hypotheses were that the type of hexagonal connection would generate different mic

10. Endodontic and prosthetic treatment of teeth with periapical lesions in a 16-year-old-girl
This paper reports the nonsurgical endodontic therapy using calcium hydroxide intracanal dressing and prosthetic treatment of 9 teeth with periapical lesions in a 16-year-old female patient. The periodontal treatment plan included oral hygiene instructions, mechanical debridement and gingivectomy in the maxillary incisors to improve gingival contouring. Root

11. Mechanical behavior of non veneered three unit fixed partial dentures of alumina-zirconia Under cyclic load in wet environment
The aim of this study was to evaluate the fatigue behavior in wet environment of a ZTA three unit FPDs processed via CAD-CAM. Thirty four three unit FPDs (In-Ceram®Zirconia BZ blanks) were grinded through a CEREC In-Lab equipment followed by glass infiltration and sandblasting. Those frameworks were then submitted to different number of load cycles (400 N,
