What is usually the recommended position for the distal margin of partial coverage restorations?

The recommended position for the distal margin of partial coverage restorations is typically just buccal to the proximal contact area. This positioning ensures several important factors are addressed in restorative dentistry.

By placing the distal margin in this manner, the restoration can achieve better adaptation to the tooth surface, promoting optimal aesthetics and function. The slightly buccal placement allows for proper contours which help mimic natural tooth anatomy, facilitating adequate occlusion and alignment with neighboring teeth. This placement also provides sufficient space for the emergence profile, allowing for appropriate plaque control and periodontal health.

Positioning the distal margin just buccal to the proximal contact helps in creating a well-defined margin that can be easily finished and polished, which is important for preventing plaque accumulation and ensuring longevity of the restoration. Additionally, this position aids in minimizing the risk of potential periodontal issues or secondary caries at the margins of the restoration.

The other options may lead to compromises in the fit or function of the restoration or could pose challenges in achieving the desired aesthetics and hygiene.
