Background: The mylohyoid bridge (MHB) is a hyperostotic anatomical variation resulting from ossification along the mylohyoid groove, potentially forming a bony canal that transmits the mylohyoid neurovascular bundle. Although historically considered an anthropological trait, its clinical relevance has increased due to possible implications in anesthesia and oral surgery. Objective: To determine the frequency and classify the morphological types of MHB in dry human mandibles, and to correlate the findings with existing literature and clinical implications. Materials and Methods: A descriptive observational study was conducted on 64 mandibular rami from 32 dry human mandibles. Specimens were examined macroscopically for the presence of MHB. Identified bridges were classified as complete or incomplete according to Hauser and De Stefano (1989), and incomplete forms were further categorized as proximal, intermediate, or distal. Data were analyzed using descriptive statistics. Results: MHB was identified in 6 out of 64 mandibular rami (9.4%). The distribution was symmetrical between sides. Bilateral occurrence was observed in 2 mandibles (6.3%), and unilateral occurrence in 2 mandibles (6.3%). Among bilateral cases, one presented complete bridges and the other incomplete bridges. All unilateral cases were incomplete, including one proximal and one distal type. No intermediate forms were identified. Incomplete forms predominated overall. Conclusion: The frequency of MHB observed is consistent with intermediate values reported in the literature, reinforcing its variability among populations. Despite its relatively low prevalence, the MHB has relevant clinical implications, particularly in anesthetic procedures and oral surgery, and should be considered during anatomical and preoperative evaluations.
