Additively Versus Subtractively Manufactured Endocrowns: Fit, Trueness, and Retention of Zirconia, Resin Composite, and Lithium Disilicate: An In Vitro Study

ALD and ZrO2 endocrowns showed superior adaptation and trueness compared to AM composite. ZrO2 exhibited the highest retention. Within the study's limitations, AM-zirconia appears to be a viable alternative to SM lithium disilicate for endocrown fabrication.
