What is the standard width of noncentric cusps?

The standard width of noncentric cusps is established to facilitate functional occlusion and ensure adequate interdigitation during occlusal movements. Noncentric cusps, also known as non-working side cusps, play a critical role in balancing occlusion during lateral movements of the mandible. The 1 mm width is optimal as it allows for the necessary contact and functional relationship with opposing cusps without compromising the integrity of the occlusion or leading to undue stress on the dental structures.

In terms of practical application, this 1 mm width is designed to provide sufficient surface area to create stable occlusal contacts while maintaining harmony in the overall occlusal scheme. Wider cusps could lead to excessive lateral forces during chewing and occlusal interferences, while narrower widths may not provide adequate support or contact. Understanding this dimension is essential for dental practitioners when planning and designing prosthetic restorations that involve occlusal considerations.
