摘要
目的 探讨氧化锆基台与常规钛基台应用于前牙区种植修复的临床效果.方法 收集前牙区种植修复患者37例共41个前牙,随机分为2组,15例19颗牙应用氧化锆基台为观察组,22例23牙应用常规钛基台为对照组,通过戴冠后1、6、12个月测量2组种植体周围牙龈出血指数（GI）和骨量吸收量;调查2组患者对修复体颜色、修复体外形、戴牙舒适度及就诊时间次数的满意度;按照改良美国公共卫生署（USPHS）标准对2组的边缘适合性能、修复体外形及颜色匹配进行临床评价;比较2组的修复效果.结果 治疗后1-6个月内,观察组的周围的骨量吸收量显著低于对照组（P＜0.05）,治疗12个月时2组差异无统计学意义（P＞0.05）,2组种植体周围牙龈出血指数差异无统计学意义（P＞0.05）.观察组患者对修复体颜色、修复体外形及戴牙舒适度的满意度显著高于对照组,就诊时间及次数满意度差异无统计学意义（P＞0.05）.观察组的边缘适合性能、外形以及颜色匹配均显著高于对照组.结论 氧化锆基台与常规钛基台应用于前牙区种植修复均可获得良好的效果,但氧化锆基台的效果明显优于钛基台,且对于种植体周围软组织及骨组织的影响较小,值得推广应用.
Objective To investigate the clinical effect of zirconia abutment and conventional titanium abutment in implant restoration in the anterior region.Methods 41 front teeth of 37 patients with implant restoration in the anterior region were randomly divided into two groups：observation group and control group.19 front teeth of 15 patients in the observation group were repaired with zirconia abutment and 23 front teeth of 22 patients in the control group were repaired with conventional titanium abutment.1,6,12 months after wearing the crown,the implant gingival bleeding index （GI） and bone uptake were measured,the satisfaction of patients on the color and appearance of implants,tooth wear comfort and treatment time and times was investigated.According to modified U.S.Public Health Service （USPHS） criteria,the marginal fit,shape and color matching of implants were evaluated in two groups.The repairing results were compared between two goups.Results Within 1-6 months after treatment,bone absorption around the implants in the observation group was significantly lower than the control group （P＜ 0.05）.12 months after treatment,there was no significant difference in bone absorption around the implants between two groups （P＞0.05）,there was no significant difference in gingival bleeding index around the implants （P＞0.05）.The satisfaction of patientson the color and appearance of implats and tooth wear comfort was significantly higher in the observation group than the control group （P＜0.05）.There was no significant difference in the satisfaction on treatment time and frequency between two groups （P＞0.05）.The marginal fit,shape and color matching of implants were better in the observation group than the control group （P＜0.05）.Conclusion Both zirconia abutment and conventional titanium abutment can get good results in implant restoration in the anterior region,but the effect of zirconia abutment is better than titanium abutment and has little effect on the soft tissue and bone tissue surrounding the implants,so it should be widely applied.
