B) 1 mm
C) 2 mm
D) 5 mm

Answer 1

The provisional is trimmed to within 1 mm of the gingival shoulder of the prepared tooth.

Therefore, correct option is B) 1 mm.

Step-by-step explanation:

The provisional, or temporary crown, is typically trimmed to within 1 mm of the gingival shoulder of the prepared tooth (B). This precision in trimming ensures an appropriate fit and facilitates optimal function and aesthetics while the final restoration is being fabricated.

The 1 mm trimming is crucial for maintaining the health of the surrounding tissues and allowing for proper emergence profile, which is essential for the long-term success of the final restoration. It also aids in preventing any interference with the patient's bite and promoting overall comfort during the provisional phase.

Therefore, correct option is B) 1 mm.
