Load-bearing capacity of pressable lithium disilicates applied as ultra-thin occlusal veneers on molars.

Purpose: The aim was to investigate the load bearing capacity of different pressable lithium disilicates cemented as occlusal veneers on molars.

Materials And Methods: One control group and six test groups were formed consisting of 20 specimens each (n = 20). The six test groups differed in the utilizing pressable lithium disilicate to fabricate occlusal veneers.

Perceptibility and Acceptability of Color Differences of Single-Tooth Implants at the Restoration and Mucosa Levels: An Exploratory Clinical Study.

Purpose: The aim of the present study was to assess the perceptibility and acceptability threshold values for color differentiation at the restoration and mucosa levels.

Materials And Methods: One restored single-tooth implant and the contralateral reference tooth were spectrophotometrically assessed in 20 patients. Perceptibility and acceptability were evaluated by dentists, dental technicians, and laypeople.
