Our clinic was addressed by a patient who complained of mobility of the front upper tooth. Actually, it was mobility of the crown part of the tooth but not the whole tooth. The tooth had been treated before and once in six months the crown got decemented. The crown came off as the tooth root had a chip under the gingiva, which caused periodic washouts of cement that kept the crown.
We suggested several variants of solving this problem:
- implant placement with further prosthetics;
- insertion of a bridge-like prosthesis, which was rejected by the patient as he did not want to have the adjacent teeth faced.
After a CT examination, we took a decision, together with the patient, on tooth root extraction and augmentation of the bone as there was no bone volume sufficient for further implantation. The bone volume decreased due to the chronic infection behind the tooth root, the CT scan showed a cyst and a perforated (punched with a post) root.
Actually, tooth restoration took 3 stages and 6 months.
