| Abstract |
|
The author observed the changes of dental arch dimensions and compared spae-maintainer group with non-space-maintainer group after primary tooth extraction. The results were as follows
1) The rate of growth of dental arch of expeirmental group in intercanine width and in inter-1st molar width was more rapid than that of the control group.
2) Arch length is almost no dimensions but it was slightly decreased in lower arch.
3) Dental arch growth and tooth eruption were stimulated by space-maintainer appliance, so it is the best way to replace a new appliance at least once a year.
4) It is thought that satisfactory conclusions in this observation must be researched successively until the mixed dentition completes. |
