Assessment of effect of accelerated aging on interim fixed dental materials using digital technologies.

Purpose: This study assessed the physical and mechanical properties of interim crown materials fabricated using various digital techniques after accelerated aging.

Materials And Methods: Three groups of interim dental restorative materials (N = 20) were tested. The first group (CO) was fabricated using a conventional manual method.

Estimation and comparative evaluation of teeth prominence values of Saudis for bracket prescription.

Background: The racial and ethnic disparities in tooth morphology and alignment indicate the need for different orthodontic prescriptions.

Purpose: This study aimed at utilizing the 3D digital models to measure the teeth prominence of Saudi adults and compare the results to previously published data.

Materials And Methods: The sample included 60 sets of 3D digital dental models of subjects who presented with non-orthodontic normal occlusion and balanced profile.
