Implant-associated cracked teeth: case series

Abstract

Abstract Background This study presents a series of 18 cases of cracked non-endodontically treated teeth that were diagnosed following the placement of adjacent implant-supported rehabilitation. These findings could suggest a possible cause/related events. Results Most of the cases occurred in female patients (61%), over 50 years old (78%, with an average age of 59 years). Nine (50%) of the cracked teeth were molars, 7 (39%) were mandibular premolars, and 2 (11%) were incisor teeth. Most of the cracked teeth (61%) had an amalgam restoration, 50% had deep periodontal pockets, and 78% had vital pulps. In 78% of patients, multiple implants were placed (with an average of 3 implants per patient). The time from implant loading to the diagnosis of a crack was longer than 1 year in 78% of cases. Conclusions The most common patient profile found in this series was a woman over 50 years old, having a cracked mandibular premolar tooth, which was diagnosed more than 1 year after reconstruction based on multiple adjacent implants. Additional clinical studies are warranted in order to shed light on this potential complication.
