When placing an implant in the lower second molar region, which is NOT a significant risk?
Show answer and explanation
Correct answer: A. Proximity to the maxillary sinus
✓ A) Proximity to the maxillary sinus is NOT a risk for the mandibular second molar.
The maxillary sinus is in the upper jaw — completely irrelevant to mandibular implant placement. Risks specific to lower second molar implant placement include: proximity to the inferior alveolar nerve (paresthesia risk), inadequate bone height above the nerve, proximity to the mandibular foramen (though this is more anterior/ramus area), and access limitations in the posterior mandible. Sinus proximity is a risk for upper posterior implants only.
