Air Abrasion Impact on Titanium Crowns by Nengsi Yusuf is a document available to read on EtoBox.

This study evaluated the effect of air abrasion on the marginal accuracy of titanium crowns with different margin configurations (shoulder, chamfer, shoulder with bevel). 90 titanium crowns were divided into groups and subjected to air abrasion with either 120μm or 250μm aluminum oxide particles. Marginal discrepancy was measured before and after air abrasion and after removing the alpha case layer. The results showed that smaller margin angles and larger particle sizes resulted in greater marginal loss. Fi
