Patient satisfaction & long-term success.

BackgroundPartial edentulism poses challenges to oral function, aesthetics, and quality of life. Implant placement techniques—freehand, pilot-drilled, and fully guided—differ in accuracy, surgical time, and outcomes. In this study, only one predefined index implant per patient was analyzed to avoid confounding from multi-implant cases, and template fabrication for the pilot-drilled group was performed using diagnostic wax-up and thermoplastic material. This study evaluated these techniques in partially edentulous patients.MethodsNinety patients were randomly assigned to three groups: freehand (n = 30), pilot- drilled (n = 30), and fully guided (n = 30). Surgery duration, implant placement accuracy, post- operative complications, early implant failure rates, and patient satisfaction were measured. Accuracy was assessed using standardized CBCT imaging at 12 months, and satisfaction was evaluated via a validated questionnaire six months after prosthetic loading.ResultsThe fully guided technique demonstrated superior accuracy (p ConclusionFully guided implant surgery outperformed other techniques in accuracy, efficiency, and patient satisfaction. These findings support fully guided, prosthetically driven workflows as a preferred option for partially edentulous patients, particularly in cases requiring high precision.背景：部分牙列缺损会对口腔功能、美学表现及生活质量造成诸多不利影响。种植体植入技术——包括徒手种植、先锋钻引导种植与完全导板引导种植——在种植精度、手术时长与临床结局方面存在差异。本研究仅对每位患者的1枚预设指标种植体进行分析，以规避多种植体病例带来的混杂偏倚；先锋钻引导组的手术模板采用诊断蜡型与热塑性材料制作。本研究在部分牙列缺损患者中评估了上述三种种植技术。 方法：将90例患者随机分为3组：徒手种植组（n=30）、先锋钻引导种植组（n=30）与完全导板引导种植组（n=30）。记录手术时长、种植体植入精度、术后并发症、早期种植体失败率及患者满意度。于术后12个月采用标准化锥形束计算机断层扫描（CBCT, Cone Beam Computed Tomography）评估种植精度，于修复体加载后6个月通过经过信效度验证的问卷评估患者满意度。 结果：完全导板引导种植技术展现出更优的种植精度（原文此处统计量p值缺失）。 结论：完全导板引导种植手术在种植精度、手术效率与患者满意度方面均优于其他技术。本研究结果支持以修复为导向的完全导板引导工作流程作为部分牙列缺损患者的优选种植方案，尤其适用于对精度要求较高的临床病例。
