(1) Background: Different techniques and tools have been developed for implant site preparation. In this clinical scenario, Hybrid Funnel Technique (HFT), a novel osteotomy procedure, has been proposed. (2) Aim: The aim of this retrospective observational study was to consider the different responses to compression of the histological bony compartments (cancellus and cortical). HFT involves the use of multiple drills for the cortical layer preparation and of an osteotome for the osteocompaction of the cancellous bone. (3) Materials and Methods: Following computer-supported implant planning and guided surgery, 10 osteotomies with HFT were performed and 10 implants with the same length and diameter were placed in seven healthy and no daily smoking patients. Periapical X-ray and intraoral photographs were performed at baseline and after 12 months of follow-up to evaluate marginal bone level (MBL) changes and aesthetic results obtained from implant prosthetic rehabilitation. (4) Results: At 1 year of follow-up, 100% of the implants were successfully integrated, MBL change mean value was 0.17 mm ± 0.21. No differences in terms of MBL were noted between thin and thick biotypes. Pink esthetic score (PES) and white esthetic score (WES), assessed one year after definitive restoration placement, were 7.5 ± 2.3 and 8.5 ± 1.1, respectively. (5) Conclusions: Based on the findings of this preliminary clinical study, HFT has led to stability of peri-implant tissues and could represent a reliable technique for surgical preparation of the implant site.
(1) 背景：已开发出不同的技术和工具用于种植体植入部位的准备。在这种临床情况下，提出了一种新型截骨术——混合漏斗技术（HFT）。(2) 目的：这项回顾性观察研究的目的是考虑组织学骨腔室（松质骨和皮质骨）对压缩的不同反应。HFT涉及使用多个钻头进行皮质层制备，并使用骨凿对松质骨进行骨压实。(3) 材料与方法：在计算机辅助种植体规划和引导手术之后，对7名健康且无每日吸烟习惯的患者进行了10次采用HFT的截骨术，并植入了10颗长度和直径相同的种植体。在基线和随访12个月后拍摄根尖片和口腔内照片，以评估边缘骨水平（MBL）的变化以及种植体修复后的美学效果。(4) 结果：随访1年时，100%的种植体成功整合，MBL变化的平均值为0.17 mm±0.21。薄型和厚型生物型之间在MBL方面未发现差异。在最终修复体植入一年后评估的粉色美学评分（PES）和白色美学评分（WES）分别为7.5±2.3和8.5±1.1。(5) 结论：基于这项初步临床研究的结果，HFT已使种植体周围组织稳定，并且可能是一种用于种植体植入部位手术准备的可靠技术。
