Case Study Number 410712
Teeth 12, 13 and 17 are existing 17XXX13,12 bridge abutments. Previous bridge done by a prosthodontist lasted 12 years. Lack of bone structure precluded implants surgery in number 16,15 and 14 and patient did not want any sinus lift surgery. Tooth number 12 became a key abutment to save without shortening its root lenght. Root canal performed 12 years ago on tooth number 12, a casted post has to be removed, broken Hedstrom file number 45 ISO also has to be removed in apical third of root canal. Tooth decay surrounded the file fragment and apical root canal size diameter had to be enlarged to 80 ISO diameter file. After re-endo, casted posts on teeth number 12,13 and a new 17XXX13,12 bridge are planned. Last Xray is a post operative X ray with cemented post and abutment 12 of 17XXX13,12 bridge.
