This study evaluated the response of canine mandibular bone to loaded hydroxylapatite-coated (HAC) and grit-blasted titanium (GT) endosseous dental implants. Four dogs were partially edentulated in the maxilla and mandible. Two implants supporting freestanding prostheses were placed in each quadrant. Following 1 and 10 months of loading, the implants were evaluated. Soft-tissue pocket depths were not statistically different between the HAC and GT implants. Crestal bone loss was not significantly different between the two implants. However, the HAC implants had a statistically significant greater amount of bone apposed to their axial and apical surfaces compared to the GT implants.
本研究评估了犬下颌骨对负载的羟基磷灰石涂层（HAC）和喷砂处理钛（GT）骨内牙种植体的反应。4只犬在上颌和下颌部分缺牙。每个象限植入2枚支持独立修复体的种植体。在负载1个月和10个月后，对种植体进行评估。HAC种植体和GT种植体之间的软组织袋深度无统计学差异。两种种植体之间的牙槽嵴骨吸收无显著差异。然而，与GT种植体相比，HAC种植体在其轴向和根尖表面附着的骨量在统计学上显著更多。
