Abstract
To obtain the information of dental arch size and the distance from one tooth center to adjacent tooth center of occlusal surface of each tooth which is perforated by Pindex system on working cast for removable die system, 600 dental casts in Busan were examined.
The distance of center of occlusal surface of each tooth and dental arch size were digitized.
The results were as follows;
1. Mean values of the distance from center of maxillary central incisor to maxillary lateral incisor(tooth number 11~12, 21~22) is 5,7 , 12~13(22~23) is 5.9 , 13~14(23~24) is 6.9 , 14~15(24~25) is 7.1 , 15~16(25~26) is 8.4 , 16~17(26~27) is 10.2 , 11~21 is 7.30 .
Mean values of the distance from center of mandibular central incisor to mandibular lateral
incisor(tooth number 31~32, 41~42) is 4.5 , 32~33(42~43) is 4.8 , 33~34(43~44) is 6.3 , 34~35(44~45) is 7.2 , 35~36(45~46) is 9.2 , 36~37(46~47) is 10.7 , 31~41 is 4.7 .
2. Mean values of the distance from the center of maxillary right central incisor to the center of maxillary left central incisor(11~21) is 7.3 , 12~22 is 18.2 , 13~23 is 26.9 , 14~24 is 37.2 , 15~25 is 43.2 , 16~26 is 48.5 , 17~27 is 53.5 .
Mean values of the distance from the center of mandibular right central incisor to the center of mandibular left central incisor(31~41) is 4.7 , 32~42 is 13.3 , 33~43 is 21.7 , 34~44 is 31.9 , 35~45 is 38.2 , 36~46 is 44.8 , 37~47 is 50.7 .
3. Mean values of the distance from the line of between 11~21 to 12~22 is 10.9 , 12~22 to 13~23 is 8.7 , 13~23 to 14~24 is 10.3 , 14~24 to 15~25 is 6.0 , 15~25 to 16~26 is 5.3 , 16~26 to 17~27 is 5.0 .
31~41 to 32~42 is 8.6 , 32~42 to 33~43 is 8.4 , 33~43 to 34~44 is 10.2 , 34~44 to 35~45 is 6.3 , 35~45 to 36~46 is 6.6 , 36~46 to 37~47 is 5.9 .
4. We checked the bottom side of cast to verify the position of dowel pin. There is no difference
upper side and lower side.
