摘要
目的 研究单纯锥度固位外连接种植体JUST J1 MINI (简称J1种植体)在前牙区窄牙槽(4.5~5.5 mm)中的临床疗效。方法 选取在南昌大学第四附属医院行前牙区窄牙槽嵴种植修复的患者12例,植入J1种植体27枚,在不行任何骨增量的情况下,均采用锥度固位外连接种植体行种植术,采用Wheeler存留标准评估种植体存留率。平均观察期为24个月,观察种植体的边缘骨吸收量,基台脱落率,种植体的折裂/折断、松动。结果 12例患者27枚J1种植体植入后6个月边缘骨吸收量为(0.069±0.032) mm,24个月为(0.142±0.079) mm,种植体6个月和24个月的边缘骨吸收量无明显差异,观察期内基台均无松动脱落,种植体的存留率为100%。结论 在不行骨增量的情况下,单纯锥度固位外连接种植体JUST J1 MINI应用于前牙区窄牙槽嵴可在短期内获得简易的美学效果。
Objective This study aims to determine the clinical effect of an external attachment implant, called JUST J1 MINI(hereafter referred to as J1 implant), with simple tonal retention on the narrow alveolar area of the anterior teeth(4.5-5.5 mm). Methods A total of 27J1 implants were implanted in 12 patients in the Fourth Affiliated Hospital of Nanchang University who were treated with narrow alveolar ridge implants. In the absence of any bone increment, all the implants were implanted with tonal retention external connection, and the survival rate of the implants was evaluated using Wheeler retention standard. The average observation period was 24 months. The amount of bone absorption at the edge of the implant, abutment abscission rate, and fracture/fracture and loosening of the implant were observed. Results The marginal bone uptake of the 27J1 implants in 12 patients was(0.069±0.032) mm 6 months after implantation and(0.142±0.079) mm 24 months after implantation. No significant difference in marginal bone uptake was observed between the implants 6 months and 24 months after implantation. No loosening of the abutment was found, and implant retention rate was 100% during the observation period. Conclusion The application of JUST J1 MINI to the narrow alveolar ridge in the anterior area can achieve a simple aesthetic effect within a short period under the condition of no bone increment.
