To assess the role of prefabricated SFI-Bar in peri-implant bone loss around immediately axially loaded and straight implants. This study comprised of 40 complete denture wearer patients who received two axially parallel implants connected by SFI-Bars in group I and two 15° mesially tilted implants connected by SFI-Bars in group II. Peri- implant bone loss (PiBL) was measured at 1 year, 2 years and 3 years. The mean PiBL at 1 year in group I was 0.21 mm and I group II was 0.22, at 2 years in group I was 0.26 mm and in group II was 0.23 mm and at 3 years, in group I was 0.29 mm and in group II was 0.34 mm. The difference was significant at 3 years (P< 0.05). The mean mesial PIBL at 1 year in group I was 0.18 mm, in group II was 0.20 mm, at 2 years in group I was 0.19 mm and in group II was 0.07 mm and at 3 years, in group I was 0.25 mm and in group II was 0.29 mm. The difference found to be significant in each time duration in both groups (P< 0.05).The mean distal PIBL at 1 year in group I was 0.23 mm, in group II was 0.22 mm, at 2 years in group I was 0.33 mm and in group II was 0.39 mm and at 3 years, in group I was 0.34 mm and in group II was 0.39 mm. The difference found to be significant at 2 and 3 years in both groups (P< 0.05). Authors found that mandibular overdentures retained with Prefabricated SFI-Bar with axial and straight inserted implants may be useful in patients with reduced bone height.
为评估预制SFI杆在即刻轴向加载的直种植体周围种植体周围骨丢失中的作用。本研究包括40名全口义齿佩戴患者，其中I组患者接受了由SFI杆连接的两颗轴向平行种植体，II组患者接受了由SFI杆连接的两颗向近中倾斜15°的种植体。在1年、2年和3年时测量种植体周围骨丢失（PiBL）。I组1年时的平均PiBL为0.21mm，II组为0.22mm；2年时I组为0.26mm，II组为0.23mm；3年时I组为0.29mm，II组为0.34mm。3年时差异有统计学意义（P<0.05）。I组1年时的平均近中PiBL为0.18mm，II组为0.20mm；2年时I组为0.19mm，II组为0.07mm；3年时I组为0.25mm，II组为0.29mm。两组在各时间段差异均有统计学意义（P<0.05）。I组1年时的平均远中PiBL为0.23mm，II组为0.22mm；2年时I组为0.33mm，II组为0.39mm；3年时I组为0.34mm，II组为0.39mm。两组在2年和3年时差异有统计学意义（P<0.05）。作者发现，对于骨高度降低的患者，使用预制SFI杆和轴向直植入种植体固位的下颌覆盖义齿可能是有用的。
