What is the recommended contouring for temporary restorations to improve gingival health?

Under-contouring is the recommended approach for temporary restorations to enhance gingival health. This method helps to ensure that the temporary restoration does not put undue pressure on the gingival tissue, which can lead to inflammation and irritation. When the restoration is under-contoured, it usually allows for better plaque control, as there is less material for plaque to accumulate on and it aids in maintaining the natural contours of the tooth and surrounding tissue.

Using under-contoured restorations helps to minimize the likelihood of gingival issues such as recession or periodontitis, as the softer tissue has more space to heal and be maintained in a healthy state. Properly managing the contours in this way contributes to overall periodontal health and supports the healing process.

Other methods, such as flat, over-contouring, or variable contouring, may not provide the same benefits to gingival health. Flat contouring can create a surface area that is easier for plaque accumulation, while over-contouring can lead to irritation of the gums and hinder healing. Variable contouring might not consistently promote optimal gingival health across all cases, making under-contouring the more reliable choice for temporary restorations.
