What is the function of the incisor pin of an articulator?

The incisor pin of an articulator serves to control vertical dimension and to maintain horizontal and vertical overlap of the anterior teeth. This component allows for precise movements and positioning of the incisal edges, which is essential for establishing proper relationships in dental occlusion. By adjusting the incisor pin, the clinician can ensure that the anterior teeth fit together correctly during functional movements, allowing for smooth occlusal contact during biting and chewing.

Understanding the function of the incisor pin is critical for achieving an accurate occlusal relationship, which is central to effective dental practice. Proper adjustment facilitates the assessment of occlusal planes and helps in the development of dental restorations that fit harmoniously within a patient's bite. Their role in managing vertical and horizontal overlap is vital for the overall functionality of dental occlusion.
