Restoration of teeth with customized CAD/CAM glass fiber posts: report of 2 cases.

This article presents 2 cases in which computer-aided design/computer-aided manufacturing (CAD/CAM) was used to fabricate glass fiber posts to restore an anterior tooth and a posterior tooth with severe coronal destruction. In the past decade, CAD/CAM technology has improved, allowing high-precision milling of customized glass fiber posts. This can enhance the biomechanical behavior of the restoration, as the post and core are milled in a single unit, decreasing the risk of failure near the core junction or in the body of the core.

Bonding Performance for Repairs Using Bulk Fill and Conventional Methacrylate Composites.

This study compared the bond strength of a composite repair made with a bulk fill composite and a conventional one using different surface treatments. Specimens were prepared as truncated cones (bases: 4 mm × 2 mm, height: 4 mm) using a bulk fill (OBFa: Filtek One) or a conventional resin (FTKa: Filtek Z250) ( = 66). They were artificially aged (10,000 cycles, 5°C-55°C, 30 sec) and subdivided according to surface treatments: NT-no treatment (control), Abr-abrasion with a diamond tip, and sand-sandblasting with aluminum oxide (50 m).

Effect of active application of self-etching ceramic primer on the long-term bond strength of different dental CAD/CAM materials.

Background: The objective of this in vitro study was to evaluate the effect of the active application of self-etching ceramic primer (ME&P) on the bond strength of different dental CAD/CAM materials (Lithium Disilicate ceramic (LD), Leucite ceramic (LE), Zirconia reinforced lithium silicate ceramic (ZLS), and Hybrid ceramic (HC)) with thermocycling aging.

Material And Methods: The samples were randomly divided into 16 groups (n = 20). Dual resin cement cylinders were made and light cured for 10 s (1.

The Effects of Patient Compliance in Supportive Periodontal Therapy on Tooth Loss: A systematic Review and Meta-analysis.

Background: The present review aimed to assess the impact of being a complier to supportive periodontal therapy (SPT), when compared to not being a complier, on tooth loss in patients with periodontitis.

Methods: Prospective and retrospective observational studies were included. MEDLINE, EMBASE, and LILACS databases were searched up to May 2019.

Influence of thickness and translucency of lithium disilicate ceramic on degree of conversion of resinous materials.

Background: In this study was assessed the degree of conversion (DC) of amine-free resin cements light cured through lithium disilicate-reinforced ceramics at different thicknesses and translucency.

Material And Methods: Specimens were divided into 21 groups (n = 5) according to luting agent used: Variolink Esthetic LC (Light shade), RelyX Ultimate (A1 shade), and Filtek Z350 XT Flow (A1 shade); the ceramic translucency: low (LT) and high (HT); and the ceramic thickness: no ceramic (control), 0.5 mm, 1 mm, and 2 mm.
