【摘要】：目的:观察慢性重度牙周炎患者行系统性牙周治疗后上颌磨牙区拔牙后即刻种植和位点保存术后延期种植两种种植方式的短期临床疗效。方法:38例慢性重度牙周炎患者导致上颌后牙区牙齿保留无望,经过系统性牙周治疗及复查提示牙周状况良好后行种植治疗,共植入修复体49枚,其中即刻种植组23枚,位点保存术后延期种植组26枚,种植术后3~6个月行修复治疗。观察种植体留存情况及修复后种植体周围组织状况。结果:种植体脱落情况:即刻种植组2枚,延期种植组1枚,存留率分别为91.30%和96.15%。两组种植体种植修复后即刻及6月后复查的PD、BI、BOP(+)相比,差异均无统计学意义(P0.05);观察期内种植成功的种植体功能良好,种植体周围软组织健康状况良好。结论:慢性重度牙周炎患者经过完善的牙周系统治疗,在牙周状况良好的条件下,上颌后牙区拔牙后即刻种植和位点保存术后延期种植短期内临床效果相当。
[Abstract]:Objective: To observe the short-term clinical effects of immediate implantation and delayed implantation after site preservation in maxillary molar region of patients with chronic severe periodontitis after systematic periodontal treatment. Forty-nine implants were implanted after good periodontal condition, including 23 in immediate implant group, 26 in delayed implant group and 3-6 months after implant preservation. The retention rates were 91.30% and 96.15% respectively. There was no significant difference in the PD, BI and BOP (+) between the two groups immediately after implant restoration and 6 months after implant restoration (P 0.05). The implants successfully implanted during the observation period had good function and the soft tissues around the implants were in good health. Under the condition of good periodontal condition, immediate implant placement and postponed implant placement in the maxillary posterior teeth area have similar clinical effects in the short term.
