Immediate functional loading of one-piece dental implants has become an accepted treatment modality for fixed restorations in fully edentulous mandibles and maxillae. Nevertheless, studies regarding immediate loading procedures in extraction sites in both the jaws, as well as in segment reconstructions and single-tooth replacements, are limited.
The purpose of this study was to evaluate the presently used protocol for immediate functional loading (within maximum 3 days) of one-piece implants which are placed according to the following methods as published by the IF.
This prospective cohort study included totally 87 consecutively treated patients who receive 1169 immediately loaded one-piece Strategic Implant, supporting fixed complete-arch maxillary or mandibular metal-ceramic bridges or segment reconstructions in both the jaws. All implants were placed by one treatment provider, who delivered also the prosthetics and controlled all cases himself over the years. Data were extracted by an experienced dentist from the patient records and from panoramic X-rays. A number of patients were interviewed at the end of the observation period. Although a total of 5100 implants were placed and observed for 12 - 57 months totally (with 105 implants out of these, having failed), this article reports the detailed results only for 1169 implants which have been followed for at least 48 months.
Immediate functional loading of using multiple, cortically anchored basal screw implants as a support for fixed full-arch and segment prosthesis in the upper and lower jaw demonstrated a high cumulative implant survival rate after an observation period of up to 57 months. Neither hypertension nor diabetes and neither smoking nor bending of the implant's neck had an influence on the success of the implants observed in this study. Within the limits of this study (5100 Strategic Implants were observed over a period of up to 57 months), "peri-implantitis" was not observed at all.
The treatment concept developed for the technology of the Strategic Implant® is safe and effective and it avoids bone augmentations and "peri-implantitis".
一体式牙种植体的即刻功能负载已成为全口无牙颌上下颌固定修复的一种可接受的治疗方式。然而，关于颌骨拔牙位点、节段性重建和单颗牙替换的即刻负载程序的研究有限。
本研究的目的是评估目前使用的针对一体式种植体即刻功能负载（最长3天内）的方案，这些种植体是按照国际口腔种植学会（IF）公布的以下方法植入的。
这项前瞻性队列研究共纳入了87例连续接受治疗的患者，他们接受了1169颗即刻负载的一体式战略种植体，这些种植体支持上颌或下颌的固定全牙弓金属烤瓷桥或颌骨节段性重建。所有种植体均由一名治疗提供者植入，多年来该提供者还负责提供修复体并亲自把控所有病例。数据由一名经验丰富的牙医从患者记录和全景X线片中提取。在观察期结束时对部分患者进行了访谈。尽管总共植入并观察了5100颗种植体12至57个月（其中105颗种植体失败），但本文仅报告了1169颗至少随访48个月的种植体的详细结果。
使用多个皮质骨锚固的基台螺钉种植体对上颌和下颌的固定全牙弓及节段性修复体进行即刻功能负载，在长达57个月的观察期后显示出较高的种植体累积存留率。高血压、糖尿病、吸烟以及种植体颈部弯曲均未对本研究中观察到的种植体成功产生影响。在本研究范围内（5100颗战略种植体在长达57个月的时间内进行观察），完全未观察到“种植体周围炎”。
为战略种植体技术开发的治疗理念安全有效，且避免了骨增量和“种植体周围炎”。
