Kauflächen

Kauflächen, also known as occlusal surfaces, refer to the biting or chewing surfaces of the teeth. Specifically, they are the parts of the posterior teeth, namely the premolars and molars, that come into contact with the opposing teeth during mastication. These surfaces are characterized by various anatomical features including cusps, grooves, and fossae. The cusps are the pointed or rounded projections on the biting surface, while the grooves are the indentations between the cusps and the fossae are broader depressions.

The primary function of kauflächen is to break down food into smaller pieces, a process essential for digestion. The complex topography of these surfaces allows for efficient grinding and shearing of food. The arrangement and occlusion of the kauflächen of the upper and lower teeth are crucial for proper chewing function. Malocclusion, or improper alignment of the teeth, can affect the efficiency of chewing and potentially lead to temporomandibular joint disorders or increased wear on the teeth.

The health of kauflächen is vital for overall oral health. They are susceptible to wear, decay (caries), and fractures. Regular dental check-ups and proper oral hygiene practices, including brushing and flossing, are important to maintain the integrity and function of these surfaces. Dental sealants are sometimes applied to the grooves and fossae of posterior teeth to prevent food particles and bacteria from accumulating and causing decay.
