据文献报道,有25％～74％的义齿基托组织面粗糙与质量不好,对义齿床粘膜有损害作用。作者研究热处理方法对于塑料表面质量的影响,共检查32个塑料标本。实验方法:用同一的石膏在相同条件下调拌制成石膏模型,用基托蜡片制作32个蜡型标本,30×50×3mm大小。分两组,第1组在前一天装盒,去蜡以后,放在干燥箱内,升温到60℃保持12小时 According to the literature, there are 25% to 74% of the denture base surface roughness and poor quality of the denture bed mucosal damage. The authors studied the effect of heat treatment methods on the quality of plastic surfaces and examined 32 plastic specimens. Experimental Method: The same gypsum was mixed under the same conditions to prepare a gypsum model, and 32 wax-shaped specimens were made with base waxes in a size of 30 × 50 × 3 mm. Divided into two groups, the first group in the previous day boxed to wax, placed in a dry oven, heated to 60 ℃ for 12 hours
