Quantitative analysis of substance removal during tooth preparation for full ceramic restorations using digitally generated preparation designs

Clinicians are encouraged to favor partial restorations whenever possible, as they result in less invasive preparations, even when compared to full crowns made from high-strength materials with reduced thickness requirements such as monolithic zirconia. To preserve tooth structure, both the material's minimum thickness and the vertical position of the finish line should be carefully considered. These findings support a conservative preparation approach tailored to material properties and clinical requirements.
