How much BL width does a guide plane require?

The correct answer is: 1/3

A 1/4 is incorrect because that would be too narrow for a guide plane to provide proper support and stability for the prosthesis. C: 1/2 is incorrect because although it is a common width for guide planes, it may not provide sufficient retention for certain patients and can cause discomfort. D: 2/3 is incorrect because this width would be too wide and can cause interference with other teeth and tissues. Overall, a guide plane usually requires a width of 1/3 for optimal function and fit.
