应用双区治疗技术行美学区不翻瓣即刻种植即刻修复:1例7年随访病例报告OA
Application of the dual-zone therapeutic technique in flapless immediate implant placement and immediate restoration in the aesthetic zone:a 7-year follow-up case report
探讨双区治疗技术在上颌前牙区不翻瓣即刻种植即刻修复中的应用效果.1 例47 岁女性患者因右上中切牙外伤致复杂冠根折无法保留,微创拔除后采用双区治疗技术行不翻瓣即刻种植即刻修复,术后7 个月制取个性化印模,完成螺钉固位的氧化锆冠修复.随访观察7 年,美学效果理想,患者满意.CBCT及平行投照根尖片检查显示种植体边缘骨水平稳定,唇侧骨板厚度良好.数字化口内扫描分析显示唇侧轮廓形态得到良好维持,无明显塌陷与吸收.经此病例分析提示,通过严格的病例筛选及规范的临床操作,双区治疗技术在不翻瓣即刻种植即刻修复病例中可获得稳定的长期美学效果.
This case report evaluates the clinical outcomes of the dual-zone therapeutic technique in flapless immediate implant placement and immediate restoration in the maxillary anterior aesthetic zone.A 47-year-old female patient presented with an irreparable crown-root fracture of the upper right central incisor caused by trauma.Following minimally invasive tooth extraction,flapless immediate implant placement and immediate restoration were performed using the dual-zone therapeutic technique.A personalized impression was taken 7 months postoperatively,and a screw-retained zirconia crown was delivered.Over a 7-year follow-up,the aesthetic outcome remained stable,and the patient reported high satisfaction.CBCT and standardized periapical radiographs taken with the paralleling technique showed a stable marginal bone level and sufficient labial bone thickness.Digital intraoral scans confirmed well-maintained labial contour without significant collapse or resorption.This case suggests that,with strict case selection and standardized protocols,the dual-zone therapeutic technique can achieve long-term stability and favorable aesthetic outcomes in cases of flapless immediate implant placement and immediate restoration.
