A stock provisional is a generic temporary replacement that may not perfectly fit the shape and size of your natural teeth.

C Prefabricated provisional may offer some customization but is generally standardized in comparison to a completely custom provisional.

D Preformed provisional is made from a mold or model of your teeth and may not look as natural as a custom provisional due to potential discrepancies in size and shape.

In comparison, a custom provisional is made specifically to fit your individual teeth and is designed to look as natural as possible. This type allows for more personalized adjustments and a better match to your natural teeth. Therefore, the most natural looking provisional is the custom option.
