目的比较分析隐形义齿与铸造支架修复前牙缺失的治疗效果和安全性。方法 288例前牙缺失患者,随机分成对照组和试验组,各144例。对照组患者使用铸造支架进行前牙缺失的修复,试验组患者使用隐形义齿进行前牙缺失的修复。治疗后随访12个月,对修复成功率以及并发症发生率进行组间比较。结果对照组患者修复成功106例,成功率73.61%;试验组患者修复成功131例,成功率90.97%,两组比较差异具有统计学意义(P<0.05)。随访12个月,对照组患者出现牙周病13例,并发症发生率9.03%;试验组患者出现牙周病11例,并发症发生率为7.64%,两组比较差异无统计学意义(P>0.05)。结论前牙缺失使用隐形义齿修复与铸造支架修复比较具有效果美观、固位性优良、舒适耐用的技术优势,同时是一种安全可靠的修复方式,不会增加牙周并发症的发生率,具有广泛的临床应用前景。
Objective To compare and analyze the therapeutic effect and safety of stealth denture and casting stent in the treatment of anterior tooth loss. Methods 288 cases of anterior teeth missing patients were randomly divided into control group and experimental group, each of 144 cases. Patients in the control group were treated with a cast stent for restoration of anterior tooth loss, and patients in the trial group were treated with a crooked denture for anterior tooth loss repair. After 12 months of follow-up, the success rate of repair and complication rate were compared between groups. Results In the control group, 106 cases were successfully repaired, with a success rate of 73.61%. 131 cases were successfully repaired in the trial group, with a success rate of 90.97%. The difference between the two groups was statistically significant (P <0.05). In the 12-month follow-up period, there were 13 cases of periodontal disease in the control group, with a complication rate of 9.03%. There were 11 cases of periodontal disease in the test group, with a complication rate of 7.64%. There was no significant difference between the two groups (P > 0.05). Conclusion The loss of anterior teeth using stealth denture prosthesis repair compared with the cast stent has the advantages of beautiful appearance, excellent retention, comfortable and durable technical advantages, but also a safe and reliable method of repair, without increasing the incidence of periodontal complications, with A wide range of clinical applications.
