The axial surface process of the mandibular first molar depends on the situation. The axial protrusion of the mandibular first molar refers to the degree of protrusion on the axial surface of the mandibular first molar (also known as the mandibular central incisor). Under normal circumstances, the axial protrusion of the mandibular first molar can help us accurately position the tooth in the oral cavity for oral examination and diagnosis. However, the specific numerical range of mandibular first molar axial protrusion will vary due to individual differences. The axial facial protrusion of the mandibular first molar is within the following range of several millimeters: the buccal facial protrusion is about 2-4 mm, the lingual facial protrusion is about 1-3 mm, and the mesial facial protrusion is about 2-4 mm. , the protrusion of the distal surface is about 1-3 mm. It should be noted that these values ??are for reference only, and actual axial surface protrusion may vary due to individual differences.

Therefore, the axial surface process of the mandibular first molar needs to be determined according to the situation
