“…However, many clinical and laboratory studies have reported that placing a post will contribute to the retention of the core portion of the restoration but may have a weakening effect on the root. [1][2][3][4][5] The use of intraradicular post and cores is complicated by the necessity to prepare an adequate ferrule, which reduces the risk of failure through root fracture. 6 Failure of post and core systems may be due to different mechanical behaviors relative to tooth structure in response to intraoral cyclic stresses.…”

Fracture resistance and mode of failure of CAD/CAM-fabricated monoblock endocrowns varies widely between materials. Clinicians should be cautious with material selection for endocrown restorations. SUMMARYThis study assessed marginal leakage and fracture resistance of computer-aided design/ computer-aided manufacturing (CAD/CAM) fabricated ceramic crowns with intracoronal extensions into the pulp chambers of endodontically treated teeth (endocrowns) using either feldspathic porcelain (CEREC Blocks [CB], Sirona Dental Systems GmbH, Bensheim, Germany), lithium disilicate (e.max [EX], Ivoclar Vivadent, Schaan, Liechtenstein), or resin nanoceramic (Lava Ultimate [LU], 3M ESPE, St Paul, MN, USA).). Thirty extracted human permanent maxillary molars were endodontically treated. Standardized preparations were done with 2-mm intracoronal extensions of the endocrowns into the pulp chamber. Teeth were divided into three groups (n=10); each group was restored with standardized CAD/CAM fabricated endocrowns using one of the three tested materials. After cementation with resin cement, specimens were stored in distilled water at 378C for one week, subjected to thermocycling, and immersed in a 5% methylene-blue dye solution for 24 hours. A compressive load was applied at 35 degrees to long axis of the teeth using a universal testing machine until failure. Failure load was recorded, and specimens were examined under a stereomicroscope for modes of failure and microleakage. Results were analyzed using one-way analysis of variance and Bonferroni post hoc multiple comparison tests (a=0.05). LU showed significantly (p,0.05) higher fracture resistance and more favorable fracture mode (ie, fracture of the endocrown without fracture of tooth) as well as higher dye penetration than CB and EX. In conclusion, although using resin

“…Posts with higher mechanical properties do not guarantee a successful survival rate, because the posts do not strengthen teeth, rather, the preparation of a post space can weaken the root 2,12) . The primary purpose of a post is to improve the retention of core materials in case of a significant loss of coronal tooth structure 12) .…”

“…There are two types of posts currently in use: custom-made cast posts and prefabricated posts. According to the composition, prefabricated posts are divided into metal (stainless steel, nickel chromium alloy and titanium alloy), ceramic, and fiber-reinforced composite (FRC) posts 2) . Metal posts have been used mainly in restorative dentistry for many years, and non-metal posts such as FRC and ceramic posts have been popular in clinical practice 3,4) .…”

The aim of this study was to estimate the flexural properties of three kinds of experimental fiber-reinforced composite (FRC) posts and to evaluate their potential use as posts. Experimental FRC posts were fabricated with glass, aramid, and UHMWP fibers. Commercial FRC posts were used for comparison. A three-point bending test was performed at a crosshead speed of 1 mm/min. Experimental glass fiber posts showed significantly higher flexural strengths and moduli than aramid and UHMWP posts. Experimental UHMWP posts demonstrated superior toughness to the commercial posts. The glass fiber posts displayed stiff, strong and brittle features, while the UHMWP posts were flexible, weak and ductile. The flexural properties of the aramid posts fell between those of the glass and UHMWP posts. In conclusion, the glass fiber posts proved excellent in flexural strengths and moduli. However, the superior toughness of UHMWP fibers suggests the possibility of their use as posts in combination with glass fibers.
