Recently, components of the extracellular cellular matrix have been assessed to enhance the biological response to dental implants. This study aims to assess the effect of surface modification with calcium ions on the early marginal bone loss of dental implants placed in a transalveolarly augmented maxillary sinus.
A retrospective study of transalveolar sinus floor augmentation was conducted in a single private dental clinic. The predictor variable was the surface of the dental implant. The primary outcome was the marginal bone loss. The secondary outcomes were the intraoperative complications and the dental implant failure. Descriptive analysis was performed for patients' demographic data and implant details.
Fifty-one patients with a mean age of 58 ± 11 years had a mean follow-up time of 13 months. Thirty-four dental implants had a Ca-modified hydrophilic surface, and 31 had no Ca (control). The experimental group showed a statistically significant lower marginal bone loss (0.36 ± 0.42 vs 0.61 ± 0.39 mm). However, there were no statistically significant differences in the implant survival. No implant failed in the experimental group while two implants failed in the control group.
The modification of an acid-etched surface with calcium ions seems to reduce the marginal bone remodeling around the dental implants, placed after transalveolar sinus floor elevation.
最近，已对细胞外基质的成分进行评估，以增强对牙种植体的生物学反应。本研究旨在评估钙离子表面改性对经牙槽嵴增高上颌窦后植入的牙种植体早期边缘骨吸收的影响。
在一家私立牙科诊所对经牙槽嵴窦底增高术进行回顾性研究。预测变量是牙种植体的表面。主要结局是边缘骨吸收。次要结局是术中并发症和牙种植体失败。对患者的人口统计学数据和种植体细节进行描述性分析。
51例平均年龄为58±11岁的患者平均随访时间为13个月。34颗牙种植体具有钙改性亲水性表面，31颗没有钙（对照组）。实验组的边缘骨吸收在统计学上显著更低（0.36±0.42对0.61±±0.39毫米）。然而，种植体存留率在统计学上没有显著差异。实验组没有种植体失败，而对照组有两颗种植体失败。
用钙离子对酸蚀表面进行改性似乎可减少经牙槽嵴窦底抬高后植入的牙种植体周围的边缘骨重塑。
