Certain anatomical features which at first may appear to give you all of one of the aims on the flip side it may interfere with another aim. An example could be an area which could potentially provide all the retention you need may prove uncomfortable for the patient.

Labial frenum - A single band of fibrous tissue which needs to be properly relieved. If not it can interfere with the stability of the denture and work against the retention. If the Frenum interferes too much then a procedure called a frenectumy can be used. This is where the Frenum is removed. Labial vestibule - Extends from labial frenum to the buccal frenum.
