摘　　要：目的:探究PRP应用于后牙区即刻种植6个月后骨改变情况。方法:收集2017年12月至2018年12月接受后牙区即刻种植患者15例,共植入植体18枚,所有患者均采用自体骨充填种植体与牙槽窝骨壁间的间隙,PRF覆盖创面,术后当天及术后6个月拍摄CT,观察术后当天及术后6个月种植体周围骨高度及颊舌侧骨板厚度。结果:术后种植体近中、远中、颊侧、舌侧骨高度分别为(2.922±1.305)mm、(1.972±1.853)mm、(2.033±1.838)mm、(1.389±1.590)mm,颊舌侧骨板厚度分别为(3.328±1.359) mm、(3.806±1.962)mm;术后六个月植体近中、远中、颊侧、舌侧骨高度分别为(2.572±1.619)mm、(1.617±1.345)mm、(0.972±2.423)mm、(0.722±1.412)mm,颊舌侧骨板厚度分别为(2.417±1.605)mm、(2.772±1.638)mm;上述种植体颊舌侧、近远中骨高度无统计学意义(P>0.05),颊舌侧骨板厚度有统计学意义(P<0.05)。结论:后牙区即刻种植6个月后骨高度及宽度均有不同程度吸收,其中颊舌侧吸收较严重。Objective: To investigate the bone changes in the posterior region immediately after the use of platelet-rich fibrin(PRF) to fill the interstitial space. Methods: From December 2017 to December2018, 15 patients were implanted immediately in the posterior region, and 18 implants were implanted.All patients were covered with PRF to cover the gap between the implant and the alveolar bone wall.CT was taken on the day after and 6 months after surgery, and the bone height around the implant and the thickness of the buccal and lingual bone plate were observed on the day after surgery and 6 months after surgery. Results: The heights of the proximal, distal, buccal and lingual bones of the postoperative implants were(2.922 ±1.305)mm,(1.972 ±1.853)mm,(2.033 ±1.838)mm,(1.389 ±1.590)mm, and cheeks.The thickness of the lingual bone plate was(3.328±1.359) mm and(3.806±1.962) mm respectively. The height of the proximal, middle, buccal and lingual bone of the implant was(2.572 ±1.619)mm,respectively.(1.617 ±1.345)mm,(0.972 ±2.423)mm,(0.722 ±1.412)mm, and the thickness of the buccal and lingual bone plates were(2.417±1.605)mm and(2.772±1.638)mm, respectively, The height of bone in the near and far was not statistically significant(P>0.05), and the thickness of the buccal and lingual bone plate was statistically significant(P<0.05). Conclusion: The immediate use of PRF in the posterior region is simple, the soft and hard tissue is well healed, and it has good short-term effects.
