背景
最初的牙种植体治疗方案 ad modum Brånemark 是基于加载前的埋入式愈合。对于患者来说，即刻种植功能可以降低成本并增加种植治疗的吸引力。
目的
本研究的目的是评估立即加载种植体放置在颌骨各个区域的短期成功率。
材料和方法
41 名患者总共接受了 127 个即刻种植种植体（76 个上颌种植体和 51 个下颌种植体）。 71% 的患者在当天接受了假肢修复，其他患者则在 11 天内接受了修复。所有假体结构均在中心咬合中完全接触。种植体加载后1周、2周、1、2、3、6和12个月进行临床随访检查。该研究在加载后一年完成。
结果
13 名患者丢失 22 颗种植体（其中 1 名患者丢失 7 颗上颌种植体）。假体负重一年后，种植体的累积成功率为82.7%。使用两阶段技术重新植入所有种植体丢失的部位，没有报告进一步的并发症。放置在上颌后部以外区域的种植体有 91% 成功，而放置在上颌后部的种植体成功率为 66%。具有功能障碍习惯（磨牙习惯）的患者的植入物比无功能障碍患者的植入物丢失的频率更高（41% 对 12%）。与未进行再生手术的植入物相比，进行引导骨再生的植入物更成功（90% vs. 67%）。
结论
即刻负重概念是除上颌骨后部以外的各种颌骨区域的现实治疗替代方案。高咬合负荷应被视为一个风险因素。另一方面，与骨缺损相结合的植入物通常会更高程度地穿透皮质层，从而有助于愈合阶段植入物的稳定性，因此不会不可避免地损害治疗结果。然而，需要进行进一步更大样本量的对照临床研究，以评估不同参数对治疗结果的影响。
BACKGROUND
The original protocol for dental implant treatment ad modum Brånemark was based on submerged healing prior to loading. For patients, immediate implant function could reduce cost and increase attractiveness of implant treatment.
PURPOSE
The goal of this study was to evaluate the short-term success rate of immediately loaded implants placed in various regions of the jaws.
MATERIALS AND METHODS
Forty-one patients received a total of 127 immediately loaded implants (76 maxillary and 51 mandibular). Seventy-one percent of the patients received their prosthetic restoration the same day and the others within 11 days. All prosthetic constructions were in full contact in centric occlusion. Clinical follow-up examinations were performed at 1 week, 2 weeks, and at 1, 2, 3, 6, and 12 months after implant loading. The study was completed 1 year after loading.
RESULTS
Twenty-two implants were lost in 13 patients (including 7 maxillary implants lost in 1 patient). The cumulative success rate of the implants was 82.7% after 1 year of prosthetic loading. All sites with implant losses were re-implanted, using a two-stage technique, with no further complications reported. Ninety-one percent of implants placed in regions other than the posterior maxilla were successful compared with 66% of implants placed in the posterior maxilla. Implants in patients with a parafunctional habit (bruxers) were lost more frequently than those placed in patients with no parafunction (41% vs. 12%). Implants subjected to guided bone regeneration were more successful compared with those not subjected to regeneration procedures (90% vs. 67%).
CONCLUSIONS
The immediate loading concept is a realistic treatment alternative in various jawbone regions except for the posterior part of the maxilla. High occlusal loads should be considered a risk factor. On the other hand, implants in combination with bone defects frequently are penetrating cortical layers to a higher extent, thereby contributing to implant stability during the healing phase and consequently do not inevitably jeopardize the treatment result. However, further controlled clinical studies with larger sample sizes need to be performed to evaluate the influence of different parameters on treatment outcome.
