Which plane is used to determine the path of placement for a veneer?

The cervical plane is pivotal in determining the path of placement for a veneer due to its relationship with the tooth's cervical area, which is where the tooth meets the gum line. This plane helps in assessing the angulation and the contour of the restoration in relation to the natural tooth structure. It also plays a crucial role in ensuring that the veneer fits properly and is aligned with the adjacent teeth, improving aesthetics and functionality.

Using the cervical plane allows the clinician to visualize how the veneer will be positioned to achieve optimal esthetic outcomes, including proper alignment and contouring of the veneer in relation to both the tooth surface and the surrounding gums. Proper consideration of the cervical plane is essential to prevent issues such as improper occlusion or inadequate bonding surface, which could compromise the longevity of the veneer.

Other planes like incisal, labial, and lingual serve important roles in various contexts of restorative dentistry but are less relevant in establishing the necessary angles and positions for veneer placement. The incisal plane is more concerned with the biting edge of anterior teeth, while the labial and lingual planes pertain to the facial aspects of anterior teeth, which do not predominantly influence the vertical alignment necessary for veneer attachment. Therefore, the cervical plane is the most appropriate reference for guiding
