The LEAST concerning force on a dental implant with regards to implant failure is:
Show answer and explanation
Correct answer: D. Vertical (axial) forces — most biomechanically favorable for implants
- A. Horizontal forces create bending moments and are more destructive to bone-implant interface.
- B. Tipping/cantilever forces create the most unfavorable stress distribution at the crestal bone — highest risk for implant failure.
- C. Oblique forces combine axial and horizontal components — more detrimental than pure axial loading.
- D. Correct. VERTICAL (axial) forces directed along the long axis of the implant are the LEAST concerning because they distribute stress evenly to the surrounding bone through the osseointegrated interface. Implants are designed to handle axial loads most efficiently — similar to natural tooth loading.
