What is the purpose of performing grooves during preparation?

Performing grooves during preparation serves to enhance retention of the dental prosthesis. Grooves can provide mechanical undercuts or surface area that helps secure the restoration in place, preventing it from becoming dislodged. In the context of prosthetic dentistry, this is especially important as it ensures that the bonded crowns, bridges, or other restorations remain intact during functional use by providing a more stable fit and increasing resistance to dislodging forces.

While occlusal alignment, evaluating the patient's bite, and reducing tooth sensitivity are important considerations in dental practice, they do not directly pertain to the specific function of grooves in the preparation process. Grooves primarily focus on aiding retention rather than influencing occlusion or bite assessment, and they do not specifically target the sensitivity of the tooth.
