The comparative study of the gingival aspect of dentures made from different flasking procedures, using scanning electronic microscopy, permits the differences in the surface texture of the resins to be assessed. This surface texture will show specific aspects for each technique. The Futurajet resin presents a surface texture with cracks of 100 microns to 200 microns long and 5 microns wide. The appearance of the polymer pellets reveals a good cohesion amongst them. The Futuracryl 2000 resin has an overall surface like an orange peel, with a hills and valleys revealing a rather weak attack of the monomer on the polymer. The palatal surface of the SR-Ivocap resin shows pleats and perpendicular fractures. The surface of the buccal aspect of the ridge is relatively smooth. The Lucitone resin shows a surface with very few irregularities, in which the polymer pellets are well dissolved. In conclusion, no porosities are found on the surface of the various resins. We think that the chemical composition of the resin influences this surface texture and the flasking technique being able to disturb the surface of the resin.
使用扫描电子显微镜对不同包埋程序制作的义齿牙龈面进行比较研究，可以评估树脂表面纹理的差异。这种表面纹理会因每种技术而呈现出特定的特征。Futurajet树脂呈现出表面纹理，有长100微米至200微米、宽5微米的裂纹。聚合物颗粒的外观显示它们之间具有良好的内聚力。Futuracryl 2000树脂的整体表面像橘子皮，有起伏，显示出单体对聚合物的侵蚀较弱。SR-Ivocap树脂的腭面显示出褶皱和垂直裂缝。牙槽嵴颊面的表面相对光滑。Lucitone树脂的表面不规则之处很少，其中聚合物颗粒溶解良好。总之，在各种树脂表面均未发现孔隙。我们认为树脂的化学成分会影响这种表面纹理，并且包埋技术可能会干扰树脂表面。
