The author measured maximum biting forces of normal persons with normal oc- clusion without prosthetic treatment from 20 to 25 of age and the patients wearing the dentures using the masticatory force meter
The following conclusions were obtained from this study.
1. The maximum biting forces of normal male were 32.45㎏ at the first molar teeth, 20.02㎏ at the first premolar and 13.67㎏ at the anterior teeth, and normal female, 33.51㎏ at the first molar, 20.75㎏ at the first premolar, and 11.75kg at the anterior teeth.
2. The maximum biting forces of male anterior and the first premolar teeth were stronger than that of female and the maximum biting forces of female the first molar teeth were stronger than that of male.
3. The maximum biting forces of the right side in the first molar teeth were stronger than left side in both sexcs and left side in the first premolar teeth were stronger than right side in both sexes.
4. In the cases of wearing the full denture, the maximum biting forces appeared 13.20㎏ at the first molar teeth, 7.30㎏ at the premolar teeth and 5.10㎏ at the anterior teeth.
5. In the cases of wearing the full dentLire, the maxilnum biting forces showed 40% at the first molar teeth, 34% at the first premolar teeth and 40% at the anterior teeth in comparison witn normal persons.
6. In the cases of wearing the partial denture, the maximum biting forces appeared 23.90㎏ at the first molar teeth and 13.85㎏ at the first premolar teeth.
7. In the cases of wearing the partial denture, the maximum biting forces showed 72% at the first molar teeth and 65% at the premolar teeth in comparison with normal persons.
