Abstract
The purpose of this study was to investigate and evaluate whether the recording information contained in the work authorization was performed properly and master casts were designed accurately according to the rationale and principles of the
removable
partial denture when the work authorization and the master casts were sent to the dental laboratory for the fabrication of the removable partial denture framework. The accurate recording of the work authorization sent to dental laboratory in
Seoul
and
Kwangju city for removable partial denture framework, the normal form of the occlusal rest and guiding plane of the surveyed crown using the surveyor, the location analysis of the occlusal rest seat, the status of the abutment splinting in the
distal
extension removable partial denture, the design pattern of the maxillary and mandibular major connectors, the use of the surveyor on the master cast, the status of the secondary impression taken in the distal extension edentulous areas were
investigated
for this study.
@ES The following analyzed results were obtained:
@EN 1. In the status of the occlusal rest seat prepared in the abutment, the occlusal rest seat with normal form was 81.25%, 95,45%, that without form was 6.25%, 0.00%, respectively in Class I and Class II on the maxillary cast and the occlusal
rest
seat with normal from was 76.92%, 95.45%, that without from was 7.69%, 0.00% respectively in Class I and Class II on the mandibular cast.
2. In the status of the guiding plane, the guiding plane with the normal from was 79.17%, 86.36%, that with abnormal from was 20.84%, 13.64% respectively in Class I and Class II on the maxillary cast and the guiding plane with normal from was
79.49%,
77.27%, that with abnormal form was 20.51%, 22.73% respectively in Class I and Class II on the mandibular cast.
3. The abutment splinting in the distal extension removable partial denture was 20.78%, 27.27%, respectively in Class I and Class II on the maxillary cast and was 25.64%, 13.64% respectively in Class I and Class II on the mandibular cast.
4. The location and form of the major connector delineated on the maxillary and the mandibular master cast was 95.83%, 98.41% respectively.
5. The delineation and recording on the work authorization was incomplete as group II (73.33%), group I (14.07%), group III(12.59%) and group IV(0.00%) in investigating the contents of the work authorization.
6. Aker’s clasp of the types of the direct retainer was nost used 72.22%, 74.60%, in the maxillary and mandibular casts respectively.
7. The location of the indirect retainer delineated on the maxillary and the mandibular master cast was 51.43%, 50.82% respectively.
8. The types of metal used were mostly Cr-Co non-precious metal alloy and the cases using color coding on the drawing paper of work authorization were not observed.
9. The cases taking secondary impression in the distal extension removable partial denture were 45.71%, 52.46% respectively in the maxillary and the mandibular master cast.
10. The delineation of tripoding or reference line on the master cast was not observed in surveying procedure.
