Abstract

|
|
Reports about the intrusion of a natural tooth bounded by implants are very rare, although some concerns have been
discussed on the intrusion of teeth connected to implants. A female aged 56 years received an implant (mandibular right
first premolar) and post/core onto root rest (mandibular right second premolar) and was restored by single zirconia crown,
respectively. Molars were implant restorations. Four month after loading, second premolar was intruded and prominent
gap was shown between opposite tooth. Because nonspecific discomfort was expressed, observation was decided after
explanation of prognosis of tooth without treatment. Three month later reversal to original position was detected on the
periapical radiographs and fully recovered position with intimate contact was completed 11 more months later. Till now 2
years and 3 month observation is being performed. Through the observation of spontaneous recovery of a natural tooth
bounded by implants, the cause of intrusion and a mechanism of spontaneous recovery could be estimated.
