Summary
This study analyzed 105 mandibles, revealing the close relationship between the mandibular canal and surrounding bone. Findings are crucial for oral and maxillofacial surgery precision.
Area of Science:
- Anatomy
- Oral Surgery
- Morphometrics
Background:
- The mandibular canal (MC) is vital for neurovascular supply to the mandible.
- Understanding MC anatomy is critical for safe surgical procedures.
Purpose of the Study:
- To morphometrically analyze the mandibular canal's position and diameter.
- To investigate the MC's relationship with mandibular cortical plates and tooth roots.
Main Methods:
- Morphometric analysis of 105 human mandibles (70 dentate, 35 edentate).
- Serial sectioning of the mandibular ramus and corpus at 0.5 cm intervals.
- Evaluation of MC proximity to cortical plates and tooth root apices.
Main Results:
- The MC closely relates to the lingual cortical plate of the mandibular ramus.
- Average MC diameter in the horizontal part is 2.6 mm.
- The MC is closest to the third molar apex and the incisive canal is present in 92% of dentate mandibles.
Conclusions:
- Morphometric data provides essential anatomical insights for oral and maxillofacial surgery.
- Precise knowledge of MC location aids in preventing surgical complications.
