Upper Teeth, Gross Anatomy

Description

Maxillary dentition is arranged in a smooth U shaped arch, from the central and lateral incisors at the anterior midline through the canines and premolars to the first and second molars posteriorly. Crown morphology is readable at the occlusal level, with incisal edges anteriorly, a prominent canine cusp at the arch corner, bicuspid premolars just posterior to it, and broader multicuspid molars forming the posterior buttress. The maxillary premolars show occlusal grooves, marginal ridges, and cusp inclines that sit superior to the corresponding mandibular teeth in normal occlusion. Enamel texture and fissure patterning are emphasized. Occlusal surface anatomy of the upper teeth matters because it dictates how forces are distributed during mastication and where plaque retention tends to occur. The maxillary first premolar often has a pronounced buccal cusp and a mesial marginal groove, a combination that becomes relevant when planning class II restorations, placing rubber dam clamps, or assessing fracture risk after endodontic access. Caries frequently tracks along pits and fissures of premolars and molars, while anterior wear facets can hint at bruxism and guide occlusal adjustment in prosthodontic work. Small landmarks. Big consequences. Dental educators can drop this asset into preclinical operative dentistry, occlusion, or dental anatomy modules when teaching cusp-fossa relationships, tooth identification, and the vocabulary of maxillary dentition. It also fits cleanly into patient facing handouts explaining why sealants target pits and fissures, or into publishing layouts discussing restorative contours for premolars and molars.
