If there is planned mutually protected occlusion, what decision should be taken by the practitioner?

In the context of planned mutually protected occlusion, providing more bulk on the buccal cusp bevel is essential for achieving the desired occlusal relationships and function. Mutually protected occlusion refers to a dental occlusal scheme where the posterior teeth protect the anterior teeth during closure, and vice versa, ensuring that each group of teeth has a specific role in occlusion.

In this scenario, the buccal cusp bevel will play a key role in guiding the occlusion towards the ideal relationship between the upper and lower teeth. A sufficient bulk on the buccal cusp areas allows for proper occlusal contacts that can distribute forces evenly, which is necessary for maintaining the integrity of the dentition and the stability of the occlusal relationships during functional movements. This bulk not only helps in achieving adequate strength and durability of the prosthesis but also aids in controlling the path of closure and minimizing the risk of interferences from adjacent teeth.

The other options, while important for different aspects of prosthetic design, do not specifically address the unique considerations required for establishing a mutually protected occlusion as effectively as the provision of bulk on the buccal cusp bevel. The accurate path of placement, sufficient convergence of preparation, and parallel proximal grooves can contribute to
