The main goal of this study was to evaluate the relationship between postoperative pain and short-term implant survival. Objective parameters, such as implant-related factors (type, diameter, length) and the surgical approach were also assessed to correlate them with pain.
This prospective, single-center study consisted of 144 patients scheduled for the surgical placement of one or more implants either with conventional surgery or with sinus-lifting together. All patients were asked to complete a questionnaire form of pain with a visual-analog scale (VAS, 1-10) for 7 days following surgery. The association of pain scores at each time-point was assessed on implant- and surgery-related factors.
The overall cumulative survival rate of 546 implants in 144 patients was 98.17 % (10 implants lost) after 1-year follow-up. No statistical difference was found in pain (VAS) scores between patients with loss and survived implants at any observation period. The length and diameter of placed implants and the presence of a sinus-lifting procedure did not influence the pain scores at any period (P > 0.05). In patients with bilateral sinus lifting, the decrease in pain scores was significant after 3 days (P < 0.05), whereas it was significant after 6 hours for the conventionally treated group (P < 0.01). Although no severe pain was reported at any time, this study found a significant difference in pain intensities among different implant brands.
This study was able to show that increased postoperative pain is not a sign of early implant failure. In addition to this, the implant dimensions and presence of sinus lifting procedure did not influence the pain experience. However, the bilateral sinus lifting prolongs the recovery time.
本研究的主要目的是评估术后疼痛与种植体短期存留率之间的关系。还评估了诸如种植体相关因素（类型、直径、长度）和手术方式等客观参数，以将它们与疼痛相关联。
这项前瞻性单中心研究纳入了144例计划通过常规手术或同期上颌窦提升术植入一个或多个种植体的患者。要求所有患者在术后7天内使用视觉模拟量表（VAS，1 - 10）完成疼痛问卷调查表。根据种植体和手术相关因素评估每个时间点的疼痛评分之间的关联。
144例患者的546枚种植体在1年随访后的总体累积存留率为98.17%（10枚种植体丢失）。在任何观察期内，种植体丢失和存留的患者之间的疼痛（VAS）评分均未发现统计学差异。所植入种植体的长度和直径以及上颌窦提升术的实施在任何时期均未影响疼痛评分（P > 0.05）。在双侧上颌窦提升的患者中，术后3天疼痛评分显著降低（P < 0.05），而在常规治疗组中术后6小时疼痛评分显著降低（P < 0.01）。尽管在任何时候均未报告严重疼痛，但本研究发现不同种植体品牌之间的疼痛强度存在显著差异。
本研究能够表明术后疼痛加剧并非早期种植体失败的迹象。除此之外，种植体尺寸和上颌窦提升术的实施并未影响疼痛体验。然而，双侧上颌窦提升会延长恢复时间。
