Which of the following principles of aesthetic consideration is not typically adhered to?

The principle of aesthetic consideration that is not typically adhered to is maximum thickness of porcelain. In prosthetic dentistry, aesthetics is a crucial element, and minimizing the visibility of metal and utilizing porcelain occlusal surfaces are practices that enhance the natural appearance of restorations.

Aesthetic considerations prioritize creating a restoration that closely mimics the natural dentition, which includes maintaining a delicate balance in the thickness of porcelain used. Excessive thickness can lead to a less natural look, overshadowing the translucency and color variations that are characteristic of natural teeth. Therefore, practitioners aim to use the minimum amount of material necessary to achieve the desired strength and aesthetic result, promoting an overall appearance that is both functional and visually appealing.

This emphasis on minimizing material thickness helps in reducing the visibility of metal components in dental work, particularly in anterior teeth where aesthetics are most important. Overall, the goal is to achieve a harmonious balance that reflects natural dental structures, avoiding any approaches that might compromise this ideal.
