目的比较分析不同种植系统埋置式与非埋置式骨水平种植体周围的骨组织变化。方法选择2008年6月至2013年5月于中国医科大学附属口腔医院种植中心接受种植修复的患者256例,总计450枚种植体。测量种植Ⅰ期、种植Ⅱ期、修复后当天及修复后1年4个时间点的数字化曲面断层片或根尖X线片,因非埋置式无二期手术,故选择与之相对应时间点的X线片,测量种植体周围骨吸收量。结果在非负荷愈合期(从种植Ⅰ期到种植Ⅱ期)及负荷1年(从修复后当天到修复后1年)两个时间段,埋置式与非埋置式愈合对Dentium、Bego及3I三种骨水平种植体周围牙槽骨吸收量的影响,差异无统计学意义(P>0.05);3种种植系统的种植体周围骨组织吸收量比较,差异无统计学意义(P>0.05)。结论采用埋置式或非埋置式种植对种植体周围骨组织吸收量没有明显影响;3种种植系统的种植体周围骨变化无明显差异,临床效果均较好。
Objective To compare and analyze the changes of bone tissue around embedded and non-embedded bone horizontal implants in different implantations. Methods From June 2008 to May 2013, 256 patients undergoing implantation and repair in the Affiliated Stomatological Hospital Affiliated to China Medical University were selected, with a total of 450 implants. Measurement of planting stage Ⅰ, planting Ⅱ, the day after repair and repair 4 points after 1 year of digital surface tomography or apical X-ray film, because of non-embedded no surgery, so choose the corresponding point in time X-ray film, measuring the amount of bone resorption around the implant. Results During the two periods of non-load healing (from planting stage Ⅰ to planting Ⅱ) and loading for 1 year (from the day after repair to 1 year after repair), burial and non-burial healed to Dentium, Bego and 3I There was no significant difference in the amount of alveolar bone around the bone implant (P> 0.05). There was no significant difference in the bone absorption between the three planting systems (P> 0.05). Conclusion Buried or non-burial implants have no significant effect on the amount of bone tissue around the implant. There was no significant difference in the bone changes around the implant between the three implantations and the clinical effect was better.
