INTRODUCTION
The popularity of one-piece implants has increased considerably among patients and dentists. The advantages of one-piece immediate loading are to reduce the number of interventions. These parameters can be better controlled with a one-piece implant.
METHODS
We considered 21 patients with one-piece implants inserted in mandible for this retrospective study. Inclusion criteria were: good oral hygiene, absence of lesions of the oral mucosa, no smoking or smoking less than 20 cigarettes a day, drinking less than two glasses of wine a day, good general health and no pregnancy.
RESULTS
We enrolled 21 (12 women and 9 men) patients in this retrospective study. The mean follow-up was 1 year. A total of 84 one-piece implants were inserted in mandible to replace 42 lower first and 42 second incisors. The diameter of the implants was 3.0mm in all fixtures. The length of the implants was equal to or longer than 12 mm in 44 and 40 fixtures respectively. Of these, 48 were inserted in women and 36 in men (age range 33 to 67; mean age 58.3 years).
CONCLUSIONS
There is no difference between the survival rates of one-piece immediate loading implants and two-piece implants and delayed loading. In conclusion, a one-piece immediate loading implant is a reliable device for mandible rehabilitation.
引言
一体式种植体在患者和牙医中越来越受欢迎。一体式即刻负重的优点是减少干预次数。使用一体式种植体可以更好地控制这些参数。
方法
我们对21例在下颌植入一体式种植体的患者进行了这项回顾性研究。纳入标准为：口腔卫生良好、口腔黏膜无病变、不吸烟或每天吸烟少于20支、每天饮酒少于两杯、总体健康状况良好且未怀孕。
结果
我们在这项回顾性研究中纳入了21例患者（12名女性和9名男性）。平均随访时间为1年。共在下颌植入84枚一体式种植体，以替换42颗下颌第一前磨牙和42颗下颌第二前磨牙。所有种植体的直径均为3.0mm。种植体长度在44枚和40枚种植体中分别等于或大于12mm。其中，48枚植入女性患者，36枚植入男性患者（年龄范围33至67岁；平均年龄58.3岁）。
结论
一体式即刻负重种植体与两件式种植体及延期负重种植体的存活率无差异。总之，一体式即刻负重种植体是下颌骨修复的可靠装置。
