OBJECTIVE
This study was done to compare the surface area of the maxillary and mandibular denture bearing area obtained through a manually molded impression in an open mouth selective pressure technique.
METHODOLOGY
Final impression was made in 60 patients with zinc oxide eugenol impression paste, poured in dental stone to get master cast. Denture bearing area was marked with an indelible pencil. The number of squares were calculated which constituted the denture bearing area.
RESULTS
Square arch form provides more surface area than ovoid and tapering which in turn increases the retention and support.
CONCLUSION
The variance and standard deviation of the surface area of square, ovoid, and tapering arch shapes of maxillary dentures were very much significant and in case of Mandibular dentures were less significant.
目的
本研究旨在比较通过开口选择性压力技术手动塑形印模获得的上颌和下颌义齿承托区的表面积。
方法
对60例患者用氧化锌丁香酚印模膏制作终印模，灌注石膏制成主模型。用不可擦除铅笔标记义齿承托区。计算构成义齿承托区的方格数量。
结果
方弓形比卵形和锥形提供更大的表面积，进而增加固位和支持。
结论
上颌义齿方形、卵形和锥形弓形表面积的方差和标准差非常显著，而下颌义齿的则不太显著。
