ProsthodonticsExplanation: Lining the baseplate with zinc oxide-eugenol impression paste
provides a more stable and accurate fit during jaw relation records. This
material can help capture the contours of the underlying tissues and minimize
movement of the baseplate, thus reducing the risk of displacing it during the
recording process. The other options may not provide the same level of
stability.

Generally it is constant.In single root it lies between one third and one half of the root apical to alveolar crest.
In multi rooted tooth it lies 1-2 mm apical to furcation
