What is the minimal preparation wall height recommended for anterior teeth?

The minimal preparation wall height recommended for anterior teeth is typically 3 mm. This measurement is significant as it provides adequate structural integrity for the restoration while ensuring that enough enamel and dentin are available for bonding. A height of 3 mm allows for optimal retention and resistance, which is critical in anterior restorations due to the aesthetic demands and functional considerations they must meet.

When preparing anterior teeth for prosthetic restoration, it’s crucial to balance the preparation depth to preserve tooth structure while also accommodating the material properties of the restoration, such as porcelain or resin composites. Insufficient wall height can jeopardize the strength and longevity of the restoration. In contrast, greater wall heights could lead to unnecessary removal of healthy tooth structure and increase the likelihood of post-operative sensitivity or other complications.

The recommended minimum of 3 mm ensures that these considerations are met, allowing for effective restoration without compromising tooth health.
