Abstract
The upper and the lower master models of Class II mod.1 by the Kennedy method of classification were duplicated to 68 identical master casts respectively, and they were sent to the dentists in the dental clinic in Seoul and Kwangju, and the
status
of
the surveying procedure, the form and type of the major connector, the form and type of the direct retainer, the location and status of the indirect retainer, and the modification of abutment were surveyed and analyzed and were compared to the
principles of th design rationale of the removable partial denture to evaluate whether or not each component of the removable partial denture framework designed by the dentists.
@ES The analyzed results were as follows:
@EN 1. The status with or without the surveying procedure was showed 7 cases (10.29) and 61 cases (89.71%) respectively.
2. Single palatal strap, A-P bar, broad palatal plate, complete coverage palatal major connector, single palatal bar, U-shaped palatal connector, and the others without drawing of the major connector were 27 cases(38.57%), 25 cases (35.71%), 5
cases
(35.71%), 5 cases (7.01%), 4 cases (5.71%), 2 cases (2.86%), 1 cases (1.43%), 6 cases(8.57%) respectively in the design patterns of the maxillary major connectors, and lingual bar, linguoplate, and others without drawing of the major connector
were
55
cases(80.88%), 11 cases (16.18%), 2 cases (2.84%) respectively in the pattern of the mandibular major connectors.
3. The direct retainer designed to the 1st bicuspid of the upper left and the lower right adjacent to the free-end edentulous area was that the design of bar clasp was 67.41% in the highest rate and that of Akers clasp was 23.36%.
4. The direct retainer designed to the 1st bicuspid of the upper right and the lower left was that the design of Akers clasp was 56.62% in the highest rate and that of bar clasp was 38.82%.
5. The mesial rests of the 1st bicuspid of the upper left and the lower right adjacent to the free-end edentulous area were 77.46%, 66.20% respectively and the distal rests and mesial rests of the 1 st bicuspid of the upper right and the lower
left
were 58.82%, 55.71%, 38.24%, 38.57% respectively and the mesial rests of the 2nd molar of the upper right and the lower left were 95.71%, 95.65% respectively, viewed from the location of the occlusal rest seat.
6. The cases without the design of the indirect retainer were 51.47% in the upper and the lower master models respectively.
7. The modification of abutments(surveyed crown) of upper and lower teeth were 8.82%, 8.82% respectively.
