Angulation of bone in lower molar area is about:
5 degrees
10 degrees
15 degrees
20 degrees
In the posterior mandible, the submandibular fossa mandates implant placement with increasing angulation as it progresses distally. Hence in the second premolar region, the angulation may be 10 degrees to a horizontal plane; in the first molar area, 15 degrees; and in the second molar region, 20 to 25 degrees.
