Patterns of innervation of the maxillary first molar: a dissection study.

Author information

  • 1Department of Oral and Maxillofacial Surgery, Ohio State University, Columbus.


Human maxillae were dissected with the aim of tracing nerves from maxillary first molar root apices to their parent superior alveolar nerve branches. The contribution of the posterior, middle, and anterior superior alveolar nerves to the innervation of the first molar was assessed. The posterior superior alveolar nerve was found to contribute innervation 100% of the time; the middle superior alveolar nerve, when present, contributed innervation 28% of the time. The anterior superior alveolar nerve did not supply any innervation to the first molar.
