Some authors have stated that wax cannot be used to make impressions for complete dentures, while others have found that wax has some advantages over elastomeric impression materials. The purpose of this study was to compare mandibular impressions made with a fluid wax to those made with light-body polysulfide rubber. Fifteen maxillary and mandibular complete dentures were made using fluid wax as a final impression material. For comparison, 15 maxillary and mandibular complete dentures were made using light-body polysulfide rubber. The number of adjustments required over 1 year was recorded. No statistical difference in adjustments was noted between the two groups.
一些作者表示蜡不能用于制作全口义齿印模，而另一些人则发现蜡相对于弹性印模材料有一些优势。本研究的目的是比较用流体蜡制作的下颌印模与用轻质聚硫橡胶制作的下颌印模。使用流体蜡作为最终印模材料制作了15副上颌和下颌全口义齿。为作比较，使用轻质聚硫橡胶制作了15副上颌和下颌全口义齿。记录了1年期间所需的调整次数。两组之间在调整方面未发现统计学差异。
