目的 两段式种植体基台连接处的微渗漏是造成种植体负重后骨吸收的重要原因,本研究体外比较3种不同连接方式的种植系统在基台连接部位的细菌微渗漏情况.方法 分别选择平台对接内六角连接、5.6°锥度连接和11°锥度连接3组不同基台和种植体连接方式的种植系统,每组各10颗.种植体的内部注入大肠杆菌的悬0浮液.安装基台后将其浸入培养液内,定期取培养液做细菌培养并计算菌落数.结果 5h后,内六角连接种植体周的培养液有菌落生长,5.6°锥度连接种植体在24h后有菌落生长,11°锥度连接种植体在48h后有菌落生长.在各时间段,内六角连接种植体周液体培养菌落数均明显高于2种锥度连接的种植体,11°锥度连接种植体细菌微渗漏小于5.6°锥度连接种植体.结论 锥度连接种植体基台和种植体连接部位的微渗漏明显小于平台对接的内六角连接种植体.11°锥度连接种植体显示有更少的细菌渗漏.
目的 兩段式種植體基檯連接處的微滲漏是造成種植體負重後骨吸收的重要原因,本研究體外比較3種不同連接方式的種植繫統在基檯連接部位的細菌微滲漏情況.方法 分彆選擇平檯對接內六角連接、5.6°錐度連接和11°錐度連接3組不同基檯和種植體連接方式的種植繫統,每組各10顆.種植體的內部註入大腸桿菌的懸0浮液.安裝基檯後將其浸入培養液內,定期取培養液做細菌培養併計算菌落數.結果 5h後,內六角連接種植體週的培養液有菌落生長,5.6°錐度連接種植體在24h後有菌落生長,11°錐度連接種植體在48h後有菌落生長.在各時間段,內六角連接種植體週液體培養菌落數均明顯高于2種錐度連接的種植體,11°錐度連接種植體細菌微滲漏小于5.6°錐度連接種植體.結論 錐度連接種植體基檯和種植體連接部位的微滲漏明顯小于平檯對接的內六角連接種植體.11°錐度連接種植體顯示有更少的細菌滲漏.

Objective The bacterial microleakage in the connection of abutment-implant is the main reason of peri-implant bone loss. The aim of the present in vitro study was to evaluate the effects of three different connection types on bacterial microleakage in the connection of abutment-implant. Methods A total of 30 implants (10 implants per group) were used. The implants presented a internal hex butt-connection (group 1), 5.6° conical connection (group 2), and 11° conical connection (group 3). The inner parts of 10 implant in each group, were inoculated with Escherichia coli suspension. Microleakage were assessed at different times. Results More bacterial leakage could be found around internal-hex butt-connection implants than conical-connection implants at any time. 11° conical connection implant showed less bacterial leakage than 5.6° conical connection implant. Conclusion The bacterial microleakage of conical abutment connection implant was less than internal hex-connection implant, and 11° conical connection had the least microleakage.
