采用光学显微镜和扫描电子显微镜对三名牙周缺损患者的组织样本进行了研究，这些患者接受了多孔羟基磷灰石种植体治疗。3个月的标本显示结缔组织通过孔隙渗透，并且沿着孔隙壁存在狭窄的骨形成区域。在4个月时，骨沉积的持续证据存在，整个植入物中明显存在骨细胞、成骨细胞和胶原纤维组织。6个月植入物有进一步证据表明骨形成持续，板层骨是孔隙内的主要成分。
Tissue samples from three subjects who had periodontal defects treated with a porous hydroxylapatite implant were investigated using light microscopy and scanning electron microscopy. The 3-month specimen showed connective tissue infiltration through the pores and a narrow zone of bone formation present along the walls of the pores. At 4 months, continued evidence of bone deposition was present with osteocytes, osteoblasts and organization of collagen fibers apparent throughout the implant. The 6-month implant had further evidence of continued bone formation with lamellar bone being the major component within the pores.
