To assess the clinical effectiveness of immediate nonfunctional loading for single-tooth implants placed in the anterior maxilla following augmentation with cancellous freeze-dried block graft.
The clinical outcomes of immediately nonfunctionally loaded implants up to 18 months after placement in the anterior maxilla were evaluated in 11 consecutive patients. Implants were immediately restored with unsplinted acrylic resin provisional crowns. Follow-up was monthly, and intraoral radiographs were obtained immediately after implant placement and at 6, 12, and 18 months. Survival rate and radiographic marginal bone loss were evaluated at 0, 6, 12, and 18 months. In the anterior maxilla, 12 implants were placed.
Marginal bone loss did not extend beyond the first thread up to 18 months follow-up, and the survival rate was 100%.
Within the limits of the present study, immediate nonfunctional loading for single-tooth implants placed in the anterior maxilla following augmentation with cancellous freeze-dried block graft seems a promising treatment alternative.
评估在前上颌骨使用松质骨冻干块状移植骨进行增量术后单颗牙种植即刻非功能性负载的临床效果。
对11例连续患者在前上颌骨植入种植体后长达18个月的即刻非功能性负载种植体的临床结果进行评估。种植体即刻用未连冠的丙烯酸树脂临时冠修复。随访为每月一次，在种植体植入后即刻以及6、12和18个月时拍摄口腔内X光片。在0、6、12和18个月时评估生存率和影像学边缘骨丢失情况。在前上颌骨共植入了12颗种植体。
在长达18个月的随访期内，边缘骨丢失未超过第一螺纹，生存率为100%。
在本研究的范围内，在前上颌骨使用松质骨冻干块状移植骨进行增量术后单颗牙种植即刻非功能性负载似乎是一种有前景的治疗选择。
