作者从1952年到1959年,共给病员戴入27付下颌骨膜下种植全口义齿。因此第一个病人距今22年,最后一个病人距今15年。对这些病人,每年检查一次,或者用信件追踪,从中得出有价值的结论。戴种植义齿的病人,可能有两个结果,或者是种植义齿在某个时候被取出,或者是病人戴着义齿死亡。当病人死亡时,义齿仍然是完整的,这种义齿可认为是绝对成功的。 The author from 1952 to 1959, a total of 27 patients wear a submandibular implant full denture. So the first patient is 22 years old and the last patient is 15 years old. Check these patients once a year, or follow up by letter, from which valuable conclusions can be drawn. Patients with dentures may have two consequences, either the implant denture is removed at some point, or the patient dies with a denture. When the patient dies, the denture is still intact and the denture can be considered absolutely successful.
