AIM
The purpose of this single case study was to evaluate the influence of different implant surfaces on human bone and osseointegration.
METHODS AND MATERIALS
A 47-year-old partially edentulous woman received two experimental implants along with conventional implant therapy. Experimental implants placed in the mandibular ramus consisted of machined and anodized surfaces, respectively. After three months of healing, the experimental implants were removed and prepared for ground sectioning and histological analysis.
RESULTS
The data demonstrate anodized implant surfaces present a higher percentage of osseointegration when compared to a machined surface in cortical human bone after a healing period of three months.
CONCLUSION
This single case study suggests an anodized implant surface results in a higher percentage of bone to implant contact when compared to machined surfaced implants when placed in dense bone tissue. However, further investigations should be conducted.
目的
本单病例研究旨在评估不同种植体表面对人体骨组织及骨结合的影响。
方法与材料
一名47岁的部分牙列缺损女性在接受常规种植治疗的同时植入了两枚实验性种植体。植入下颌升支的实验性种植体分别具有机械加工表面和阳极氧化表面。愈合三个月后，取出实验性种植体并制备磨片进行组织学分析。
结果
数据表明，在三个月的愈合期后，与机械加工表面的种植体相比，阳极氧化表面的种植体在皮质骨中的骨结合百分比更高。
结论
本单病例研究表明，与机械加工表面的种植体相比，置于致密骨组织中的阳极氧化表面种植体具有更高的骨-种植体接触百分比。然而，仍需进一步研究。
