Prosthodontics & Occlusion · single question
A patient opts to crown teeth 2, 4, and 6 after caries excavation. What is the ideal minimal angulation for the crown preparation taper?
Show answer and explanation
Correct answer: B. 2-5 degrees
An ideal taper of 2-5 degrees ensures proper retention and resistance of the crown while maintaining adequate structural integrity. A taper larger than 10 degrees may compromise crown retention, while a taper less than 2 degrees can be challenging to seat the crown.
