Implant surface topography using bioactive material provides faster bone-to-implant healing. This histological report described the analysis of human bone tissue around an immediately loaded implant, with BPC (Biphasic Calcium Phosphate) grit-blasted surface treatment, after two months of healing. Two temporary mini-implants (2.8 × 10 mm) with BPC grit-blasting surfaces were placed and immediately loaded to retain a complete interim denture. After a 60-day healing period, one mini-implant was removed for histologic analysis. The ground section showed the whole implant surrounded by healthy peri-implant tissues. Implant surface presented a close contact with newly formed bone, showing some areas of osteoblasts secreting mineral matrix. The ground section depicted a bone contact of 60.3 + 8.5%. The BPC grit-blasted surface was biocompatible and enabled the osseointegration process after a short-term period.

使用生物活性材料的种植体表面形貌可提供更快的骨-种植体愈合。本组织学报告描述了在愈合两个月后，对一枚即刻负重种植体周围的人骨组织进行的分析，该种植体采用了双相磷酸钙（BPC）喷砂表面处理。放置了两枚具有BPC喷砂表面的临时微型种植体（2.8×10毫米）并即刻负重以固定一副完整的过渡义齿。在60天的愈合期后，取出一枚微型种植体进行组织学分析。磨片显示整个种植体被健康的种植体周围组织所包围。种植体表面与新形成的骨紧密接触，可见一些成骨细胞分泌矿物质基质的区域。磨片显示骨接触率为60.3 + 8.5%。BPC喷砂表面具有生物相容性，并能在短期内实现骨结合过程。
