摘要
目的:评估改良式印模法制取印模获得的牙龈穿龈形态的准确率。方法:选取20位前牙缺失种植患者,制作粘戴临时义齿并不断调改以诱导牙龈成型,测量龈乳头至龈缘标记点的垂直距离,采用传统和改良式印模法制取印模,获得缺牙区穿龈形态,再次测量龈乳头至龈缘标记点的垂直距离,并与取模前距离进行比较。结果:对比传统印模法,该实验采用改良式印模法复制的牙龈穿龈形态对比取模前没有显著变化。结论:改良式印模法能精确复制牙龈穿龈形态,获得理想的临床美学修复效果。
Objective:To evaluate the accuracy of gingival perforation by modified impression method.Methods:Twenty patients with anterior tooth loss were fitted with temporary crowns which adjusted to induce gingival formation,measure the vertical distance from the gingival papilla to the gingival margin marker.Making traditional and improved impression in the edentulous area,measure the distance again and compared with the distance before taking the module.Results:There was no statistical significant difference in gingival perforation pattern between pre-impression and modified impression.Conclusion:Modified impression method can accurately reproduce the gingival perforation morphology and obtain ideal clinical aesthetic repair effect.
