Trial summary
This case report presents the long-term prognosis of an implant resulting in late failure with an osteointegrated root remnant on the fixture 11 years after implant placement.

About this study
Official title: Long-Term Prognosis Of An Implant Osteointegrated With The Root Remnant On-Site: A Case Report
This case report presents the long-term prognosis of an implant resulting in late failure with an osteointegrated root remnant on the fixture 11 years after implant placement. A 68-year-old female patient experienced issues with a maxillary right 4-unit implant-supported bridge placed 11 years ago. During removal, an osteointegrated root remnant was discovered on the middle supporting implant, which had been inadvertently placed over it. Clinicians should be cautious with retained root remnants, as they may impact osteointegration. However, both the implant and root fragment were osteointegrated without adverse effects.
Read the detailed description
There is a growing demand for implant dentistry as the first rehabilitation choice for treating patients with missing teeth. Clinicians can encounter asymptomatic retained root fragments in edentulous spaces. This case report presents the long-term prognosis of an implant resulting in late failure with an osteointegrated root remnant on the fixture 11 years after implant placement. A 68-year-old female patient presented to the clinic with complaints of function related to a maxillary right 4-unit implant-supported bridge 11 years after the first insertion of the implants. After removal of the restoration, a root remnant was observed as osteointegrated on the fixture of the middle supporting implant. The implant was placed encroaching upon the mesial part of the residual root fragment left unintentionally, which was discovered accidentally during bridge removal. Clinicians should show ultimate attention when utilizing the retained root remnants in implant sites considering the potential risk of hindering osteointegration. However, osteointegration of the encroached implant and root fragment is plausible, with no observed adverse effects. A risk-benefit evaluation should be assessed individually.

What is being measured
The primary outcome is the main question the study is designed to answer.
Dental Implant Osteointegrated With The Residual Root
The prognosis of the osseointegration status of the retained root remnant and dental implant over an 11-year follow-up period.
Whether osseointegration has occurred will be verified based on follow-up radiographic images and periodically recorded examination data. Evaluation criteria include implant stability, compatibility with surrounding bone and soft tissues, and potential inflammatory reactions around the root remnant. These measures are intended to understand the long-term integration of the implant and root remnant.
Measured: From enrollment to the end of treatment at 11 years
