纵向调查研究表明,成功的种植体在植入后不久就有革蓝氏阳性为主的兼性菌丛生长。反复采集临床种植成功患者口内微生物标本,连续5年以上的检查结果证实,菌丛成分没有明显改变。然而,在种植体周围出现骨丧失和病理性牙周袋患者口腔内,却发现显著不同的菌丛生长,即为革蓝氏阴性厌氧菌。尤其是梭 Longitudinal studies have shown that there is a facultative flora that predominates in Gram-positive colonies soon after implantation. Repeated acquisition of clinical planting successful oral microbial specimens for more than 5 consecutive years of test results confirmed that the composition of the flora did not change significantly. However, in the mouth of patients with bone loss and pathological periodontal pocket around the implant, significant differences in the growth of the flora were found, that is, Gram-negative anaerobes.
