| ［摘要］ 目的 研究三类牙槽嵴患者制取开闭口式硅橡胶印模后全口义齿修复的边缘适合性。方法 选取2016-01～2018-01在修复科就诊的全口牙列缺失患者，按照Atwood分级法，二级牙槽嵴18例，三级牙槽嵴20例,四级牙槽嵴12例。将这三类牙槽嵴又各自等分为观察组和对照组，每组25例。观察组采用闭口式硅橡胶印模行全口义齿修复。对照组采用开口式硅橡胶印模行全口义齿修复。修复后1个月内，统计患者因边缘不合适来诊的次数、调磨的区数及各区调磨过的次数。结果 全口义齿修复1个月内，三类牙槽嵴中观察组调磨的次数均显著少于对照组（P<0.05），尤其是四级牙槽嵴（P<0.01）。观察组三级和四级牙槽嵴调磨的区数显著少于对照组（P<0.05）。观察组二级牙槽嵴调磨的区数与对照组比较差异无统计学意义（P>0.05）。其中下颌磨牙区边缘调磨的次数为最多，其次为上颌磨牙区。结论 闭口式硅橡胶取模制作的全口义齿边缘适合性要明显高于开口式硅橡胶取模，而且在牙槽嵴条件越差的时候效果越明显。 |

| ［Abstract］ Objective To study the edge suitability of the complete denture repair of three types of alveolar ridge patients with open or closed-mouth silicone rubber impression. Methods The edentulous patients were chosen in our hospital between January 2016 and January 2018 and were performed complete denture repair, and were classified according to Atwood taxonomy, including 18 patients with level 2 alveolar ridge, 20 patients with level 3 alveolar ridge and 12 patients with level 4 alveolar ridge. Each of the three types of alveolar ridge was divided into observation group(n=25) and control group(n=25). The observation group was treated with complete denture repair and closed silicone rubber impression, while the control group was treated with complete denture repair and open type silicone rubber impression. Within one month after repairment, the number of the patients who visited the doctors due to inappropriate denture edges, the number of grinding areas and the number of times each area had been ground were statistically analyzed. Results Within one month after repairment, the number of times each area had been ground in the three types of alveolar ridge in the observation group was significantly less than that in the control group(P<0.05), especially in the level 4 alveolar ridge(P<0.01). In the observation group, the number of grinding areas in the level 3 and level 4 alveolar ridge was significantly less than that in the control group(P<0.05), and there was no significant difference in the number of grinding areas in the level 2 alveolar ridge between the observation group and the control group(P>0.05). In the mandibular molar area, the number of grinding is the most, followed by the maxillary molar area. Conclusion The edge suitability of the complete denture by the closed-mouth silicone rubber impression is obviously higher than that by the open silicone rubber impression, and the effect is more obvious when the condition of alveolar ridge is worse. |
