Effect of Margin Designs on the Marginal Adaptation of Zirconia Copings

Acta Stomatologica Croatica, 2017
The aim of this in vitro study was to investigate the effect of Shoulder versus Chamfer margin design on the marginal adaptation of zirconia (Zr) copings.40 extracted molar teeth were mounted in resin and prepared for zirconia crowns with two margin preparation designs (20=Shoulder and 20=Chamfer).

Adaptive margins for online adaptive radiotherapy [PDF]

Physics in Medicine & Biology, 2022
Abstract Objective. In online adaptive radiotherapy a new plan is generated every fraction based on the organ and clinical target volume (CTV) delineations of that fraction. This allows for a planning target volume margin that does not need to be constant over the whole course of treatment, as is the case in ...
