RPD Review Questions
For maxillary major connectors, except where plating is used, the border of the major connector should be at least ______ mm away from the gingival margin.
For the anterior-posterior palatal strap maxillary major connector, the anterior, posterior, and lateral straps should be about ______ mm wide.
at least 10
The basic philosophy of dental treatment for a partially edentulous patient is to
preserve what remains and restore what is missing
replace the missing teeth
improve the path of insertion
reshape rotated teeth
It is best not to use a balanced occlusion when mandibular RPDs oppose maxillary complete dentures.
The function of the guide plate is to
help establish a definitive path of insertion/dislodgement.
stabilize the RPD by controlling its horizontal position.
provide contact with the adjacent tooth.
all of the above
What is the design error in the maxillary RPD framework shown to the right?
The anterior teeth should have been plated.
An anterior-posterior palatal strap major connector should have been used.
There should be a cast circumferential clasp on tooth #6.
The posterior border of the major connector should cross the palate at right angles to the midline.
What would be the best denture base connector when there is limited interocclusal space (<3 mm).
All metal base
All plastic base
The first consideration in developing occlusion is the evaluation and establishment of the correct position of the occlusal plane. This may be compromised by super-erupted and malposed teeth.
Your patient's partially edentulous arch is depicted in the illustration to the right. The missing teeth (with the exception of the third molars) were extracted three weeks ago. What would be the best denture base/replacement teeth combination in this instance?
Metal bases with beads for attachment of processed tooth colored acrylic resin.
An all metal base
A wrought wire clasp is NOT used in which of the following situations?
On a terminal abutment of an extension RPD.
As an embrasure clasp.
On a tooth with an indirect retainer on it.
Both 1 and 2 above.
