Dental Dentures: Partial | Cosmetic Dentistry
As in the lower arch, there are no indications for the use of a lingual plate in the upper arch. The argument often heard that the lingual plate is more easily repaired is not valid because the lingual plate itself is often responsible for the premature need to extend the prosthesis.
The denture base departs at a blunt angle from the terminal tooth at the junction between tooth and saddle (Fig. 12).
The rugae palatinae should remain uncovered whenever possible. This not only allows for the continued self-cleansing and massaging effect of the tongue and saliva, but also avoids any unnecessary impediment in speech (see also, Chap. 7 “Special Statics”) (Fig. 13).
The finished denture base.
The clasp-saddle junction lies disto-lingually because the retention is found on the buccal surface.
The tuberosity is enclosed. The denture base must be sufficiently sturdy. (Fig. 14).
