In human anatomy, the facial skeleton of the skull the external surface of the mandible is marked in the median line by a faint ridge, indicating the mandibular symphysis (Latin: symphysis menti) or line of junction where the two lateral halves of the mandible typically fuse in the first year of life (6–9 months after birth). [1]

The mandibular symphysis (mental symphysis or symphysis menti) is the vertical, sometimes indistinct, line found along the midline on the body of the mandible. It marks the site of fusion between the right and left halves of the mandible that unite during its development.

Nov 3, 2023 · The mandibular symphysis: Fibrous tissue in the midline of the mandibular body, which ossifies by the first year of life. It unites the left and right halves of the mandible in order to form a single, symmetrical bone. The mental protuberance: …

Jan 6, 2025 · It bears the lower teeth through the alveolar process. The body of the mandible is curved, somewhat like a horseshoe, with two surfaces and two borders. The mandibular symphysis is located in the midline, a point of fusion. The parasymphysis extends from the midline to past the canine.

The mandibular symphysis, also referred to as the symphysis menti, is essentially the fusion point of the line where the right and left halves of the mandible come together.

Feb 7, 2022 · Mandibular symphysis is a bony landmark present in the midline of the mandible. It is a small bone ridge representing the fusion of the two halves during development. Laterally to the ridge and below the incisive teeth, there is a depression known as the incisive fossa.

Symphysis Menti a.k.a. Mandibular Symphysis is a slight median rim which is located at the external surface of the body of mandible. The line which shows the fusion that appears at the age of 2 years of the two halves of the mandible is indicated by symphysis menti.

These are simple fractures in the area between the canine teeth of the mandible. Orthopantomogram of a simple symphyseal fracture. This image shows a PA view of the same …

The purpose of the present study was to assess the symphyseal morphology and lower incisor angulation in different anteroposterior relationship and in different growth patterns and to investigate whether the symphyseal morphology had any correlation with dentofacial parameters.

There are multiple key anatomical landmarks in each of these areas that are crucial to be aware of for nerve and muscle anatomy. The body of the mandible is the horizontal portion that can be divided in to two parts: Within the alveolar bone, interalveolar septa travel from the buccal bone to the lingual bone to create tooth sockets.
