The aim of the study is to analyze the effect of different materials and techniques in current use on peripheral shaping of complete denture impression.
The present study was conducted to compare and evaluate the maxillary border morphology produced using tissue conditioner as control and low fusing impression compound, Polyether, Pattern resin and periphery wax as border molding materials. The study was carried out on 15 denture wearer patients with well formed, rounded edentulous maxillary arch with adequate width and height. On each patient, border moldings were done, with tissue conditioner which was loaded on the borders of previous maxillary denture of the patient (control group), low fusing impression compound (Group 1), polyether (Group 2), Pattern resin (Group 3) and Peripheral wax (Group 4), respectively on special tray made for the patient. Sulcus width height and area was then measured for each group using stereomicroscope.
Based on the study it is concluded that the polyether was the best material for border molding which will give most accurate borders to a denture.
本研究旨在分析当前使用的不同材料和技术对全口义齿印模边缘整塑的影响。
本研究通过使用组织调节剂作为对照,以及低熔合金印模材料、聚醚、模型树脂和边缘蜡作为边缘整塑材料,来比较和评估上颌边缘形态。该研究选取了15名佩戴义齿的患者,其无牙上颌弓形态良好、呈圆形,宽度和高度适宜。对每位患者,分别在为其制作的专用托盘上,使用加载于患者上颌旧义齿边缘的组织调节剂(对照组)、低熔合金印模材料(第1组)、聚醚(第2组)、模型树脂(第3组)和边缘蜡(第4组)进行边缘整塑。然后使用体视显微镜测量每组的龈沟宽度、高度和面积。
基于本研究得出结论,聚醚是边缘整塑的最佳材料,能为义齿提供最精确的边缘。
