After impression-making procedures, remnants of Xantopren impression material were found in the gingival crevices in eight of 125 patients. In three of the eight patients, remnants were only discovered subsequent to a systematic exploration with a fine curette. In all eight of the patients in which material was found in the crevice, the location corresponded with defects in the impression itself. Although eight of 125 is not a statistically significant number, it would be nonetheless prudent to consider a routine curettage of abutment sulci after impression-making. This procedure is even more strongly recommended should a defect be detected in the crevicular region of the impression. Impressions should remain in the mouth until full setting and maximum tear strength is reached. Strict adherence to the manufacturers' instructions is necessary.
在取印模操作后，125例患者中有8例的牙龈沟内发现了赞托普伦印模材料残留。在这8例患者中的3例中，仅在使用精细刮匙进行系统探查后才发现残留。在所有8例牙龈沟内发现材料的患者中，材料位置与印模本身的缺陷相对应。虽然125例中的8例并非具有统计学意义的数字，但取印模后常规刮治基牙龈沟仍是谨慎之举。如果在印模的龈沟区域检测到缺陷，则更强烈推荐此操作。印模应保留在口腔内直至完全凝固并达到最大撕裂强度。必须严格遵守制造商的说明。
