What is the optimal implant placement location for bilateral implants in a mandibular implant-retained overdenture?
Show answer and explanation
Correct answer: C. Canine regions bilaterally
For a two-implant mandibular overdenture, bilateral canine positions are optimal: maximum anterior-posterior spread for stability, avoids mental foramen, excellent bone height/width in anterior mandible, optimal biomechanics for retention.
- A. Premolar regions are acceptable but canine position provides slightly better biomechanics.
- B. Molar regions — more bone resorption, closer to IAN — less ideal.
- C. CORRECT. Bilateral canine positions = optimal for two-implant mandibular overdenture.
- D. Incisor regions — less A-P spread, limited bone volume.
