Fracture resistance of bonded CAD/CAM restorations with standard or extended preparations.

The purpose of this study was to evaluate the fracture resistance of teeth with standard or extended mesio-occlusodistal (MOD) preparations after restoration with bonded computer-aided design/computer-aided manufacturing (CAD/CAM) materials. Standard or extended MOD cavities were prepared in 60 of 70 extracted, caries-free third molars. In the standard MOD preparations (n = 30), 4.

Translucency and strength of high-translucency monolithic zirconium oxide materials.

The purpose of this study was to evaluate the translucency and strength of highly translucent monolithic zirconia ceramic materials recently introduced to the market. Four monolithic zirconium oxide materials promoted as having high translucency (BruxZir Shaded 16, BruxZir HT, Lava Plus, and inCoris TZI C) were compared to a high-translucency, lithium disilicate monolithic glass-ceramic material (IPS e.max CAD HT).

Microtensile bond strength of lithium disilicate to zirconia with the CAD-on technique.

Purpose: Recently, a novel technique was introduced to combine lithium disilicate and zirconia into one restoration. The purpose of this study was to compare the microtensile bond strength of veneering ceramic to a zirconia core in two techniques: the e.max® CAD-on technique and the Press-on technique.

Total nasopharyngeal stenosis: treatment with laser excision, nasopharyngeal obturators, and topical mitomycin-c.

Objective: Severe nasopharyngeal stenosis after uvulopalatopharyngoplasty (UPPP) is a dreaded complication. Very little has been written about successful treatment because attempts at correction frequently fail. Severe stenosis of the nasopharynx drastically worsens speech, swallowing, and obstructive sleep apnea (OSA).
