摘　　要：目的 :研究2种种植体对种植体周围软组织的影响。方法 :选择2020年12月—2021年2月普陀区眼病牙病防治所收治的单颗后牙缺失且需行种植修复的患者40例,其中植入骨水平种植体10例,软组织水平种植体30例。在完成种植冠修复当天、3个月、6个月及12个月时比较2组种植体的探诊深度,检测种植体龈沟液中天冬氨酸转氨酶(AST)和碱性磷酸酶(ALP)水平。采用SPSS 17.0软件包对数据进行统计学分析。结果:修复完成当天、3个月、6个月及12个月,软组织水平种植体的探诊深度和ALP水平均显著低于骨水平种植体(P<0.05)。其中修复完成当天,软组织水平种植体的AST显著低于骨水平种植体(P<0.05)。随着时间增加,骨水平种植体龈沟液中的AST迅速降低,最后与软组织水平种植体接近(P>0.05)。结论:尽管骨水平种植体和软组织水平种植体均具有良好的临床使用效果,但软组织水平种植体周围的软组织表现出更好的稳定性。PURPOSE: To investigate the effect of different implant systems on peri-implant soft tissue. METHODS:Forty patients requiring single implant therapy in posterior teeth at Dental and Ophthalmic Clinic of Putuo District from December 2020 to February 2021 were selected. Ten patients were implanted with bone level implants and 30 patients with soft tissue level implants. Periodontal exploration was performed at the buccal side, lingual side, mesial and distal axial angle of the implants, and the gingival crevicular fluid of these locations were taken to detect the enzyme level. The probing depth, aspartate aminotransferase(AST) and alkaline phosphatase(ALP) level of the two groups were compared at the day, 3 months, 6 months and 12 months after crown restoration. Statistical analysis was completed by SPSS 17.0 software package. RESULTS: The probing depth and ALP level of soft tissue level implants were significantly lower than those of bone level implants at the day, 3 months, 6 months and 12 months after crown restoration(P<0.05). At the day when crown restoration was accomplished, AST of soft tissue implant was significantly lower than that of bone level implant(P <0.05). AST in gingival crevicular fluid of bone level implants decreased rapidly in the following three time periods, and close to that of the soft tissue level implants(P>0.05) at last. CONCLUSIONS: Both bone level implants and soft tissue level implants have good clinical effects, but peri-implant soft tissues of the soft tissue level implants show better stability.
