Immediate implant placement and immediate chairside provisionalization in the esthetic zone require meticulous treatment planning. A digital workflow that combines intraoral scans and a cone beam computed tomography scan can be used to visualize the surgical and restorative aspects of the treatment and to plan a prosthetically driven implant position. A digital workflow in implant dentistry enables the prefabrication of an individualized CAD/CAM temporary restoration, based on the planned implant position. This could be a predictable method to deliver a screw-retained temporary restoration, directly after static computer-assisted immediate implant surgery. . Three patients with a failing tooth in the maxillary esthetic zone were treated with immediate implant placement and chairside provisionalization using this digital workflow. After 3 months, a final restoration was placed. Clinical, radiographic, and patient-reported outcome measures were collected prior to implant treatment, 6 weeks after placing the temporary restoration and then 1 month and 1 year after placing the final restoration. . At the 1-year follow-up, healthy soft tissues were observed, and peri-implant bone levels were stable. Patient satisfaction after the treatment was high.
The three reported cases demonstrate the potential for predictable immediate implant placement and chairside provisionalization using a digital workflow.
在美学区域进行即刻种植和即刻椅旁临时修复需要精心的治疗计划。结合口内扫描和锥形束计算机断层扫描的数字化工作流程可用于可视化治疗的手术和修复方面,并规划以修复为导向的种植体位置。种植修复的数字化工作流程能够根据规划的种植体位置,预先制作个性化的CAD/CAM临时修复体。这可能是在静态计算机辅助即刻种植手术后直接提供螺丝固位临时修复体的一种可预测方法。三名上颌美学区域牙齿失败的患者采用这种数字化工作流程进行了即刻种植和椅旁临时修复。3个月后,进行了最终修复。在种植治疗前、放置临时修复体6周后、放置最终修复体1个月和1年后收集临床、影像学和患者报告的结局指标。在1年随访时,观察到软组织健康,种植体周围骨水平稳定。治疗后患者满意度较高。
所报告的三个病例证明了使用数字化工作流程进行可预测的即刻种植和椅旁临时修复的潜力。
