This study aimed to histologically evaluate the effects of XPEED and SLA surface on the mineral apposition rate (MAR) at 3 and 5 weeks in titanium dental implants placed in human bone. In total, 17 titanium dental implants with XPEED surface ( = 9) used as test and SLA surface ( = 8) used as control were included in this study. Each patient received four doses of tetracycline 500 mg at 12 h intervals 2 weeks prior to biopsy retrieval. Implant retrieval was performed, and retrieved biopsies were carefully treated for histomorphometric evaluation under epifluorescence microscopy. At 3 and 5 weeks, newly formed bone appeared in direct contact with both types of tested surfaces. At 3 weeks, the MAR value was, respectively, 2.0 (±0.18) μm/day for XPEED implants and 1.5 (±0.10) μm/day for SLA implants ( = 0.017). At 5 weeks, lower MAR values for both XPEED and SLA implants were noted, with 1.2 (±0.10) μm/day and 1.1 (±0.10) μm/day, respectively ( = 0.046). The overall evaluation by linear regression analysis for both time and implant surfaces showed a decreased osteoblast activity at 5 weeks compared to 3 weeks ( < 0.005). The results of the present study show that the bone apposition rate occurs faster around implants with XPEED surface at 3 weeks and 5 weeks of healing. MAR values may support the use of implants with XPEED surfaces in early loading protocols.
本研究旨在通过组织学方法评估XPEED和SLA表面对植入人体骨内的钛牙种植体在3周和5周时的矿物质沉积率(MAR)的影响。本研究共纳入17枚钛牙种植体,其中9枚采用XPEED表面作为试验组,8枚采用SLA表面作为对照组。在活检取材前2周,每位患者每隔12小时接受4剂500mg四环素治疗。进行种植体取出,并对取出的活检组织进行仔细处理,以便在落射荧光显微镜下进行组织形态计量学评估。在3周和5周时,新形成的骨与两种测试表面均直接接触。在3周时,XPEED种植体的MAR值分别为2.0(±0.18)μm/天,SLA种植体为1.5(±0.10)μm/天(P = 0.017)。在5周时,XPEED和SLA种植体的MAR值均较低,分别为1.2(±0.10)μm/天和1.1(±0.10)μm/天(P = 0.046)。通过线性回归分析对时间和种植体表面进行的总体评估显示,与3周相比,5周时成骨细胞活性降低(P < 0.005)。本研究结果表明,在愈合3周和5周时,XPEED表面种植体周围的骨沉积速率更快。MAR值可能支持在早期加载方案中使用XPEED表面的种植体。
