Dislodged Dental Implant Travels Through Body in Rare Case
A remarkable case published in the journal Oral and Maxillofacial Surgery Cases details the unusual journey of a dental implant that became dislodged during surgery and was naturally expelled from a patient’s body through a complex route. The incident highlights the potential, though rare, complications associated with dental implant procedures and the body’s surprising ability to address them.
Implant Displacement and Initial Symptoms
The case involved a 44-year-old man undergoing dental implant placement at a Military Academy Hospital in Prague, Czech Republic. During the procedure, the implant inadvertently moved into the maxillary sinus – the space within the upper jaw. Following the displacement, the patient experienced pain radiating from the sinus to his head, pus-like discharge from one nostril, and nasal congestion.
Diagnostic Imaging and Unexpected Findings
Referred to Prague Military School Hospital, a CT scan revealed inflammation in the right maxillary sinus caused by the implant. Initially, the medical team planned surgical removal approximately four weeks after the incident. However, a pre-surgical CT scan surprisingly showed the implant was no longer visible in the sinus.
Further investigation with chest and abdominal X-rays revealed the implant had migrated to the lower right abdomen. This unexpected finding led the medical staff to monitor the implant’s movement, anticipating natural discharge.
Natural Expulsion and Resolution
Over the following two weeks, X-rays confirmed the implant continued to descend through the patient’s system. By 14 days after the initial displacement, the implant had completely disappeared from the body. Importantly, the maxillary sinus inflammation and associated pain had also resolved.
Proposed Mechanism of Expulsion
The medical team theorized that the implant had moved from the maxillary sinus to the back of the nasal cavity, exiting through the mouth and being inadvertently swallowed during sleep. The maxillary sinus is lined with cilia, tiny hair-like structures that move mucus, pathogens, and foreign substances towards the nasopharynx – the upper part of the throat behind the nose – and ultimately into the gastrointestinal tract. The implant likely followed this pathway.
Potential Complications and Treatment
The medical staff emphasized that a dislodged implant in the maxillary sinus can lead to chronic sinusitis due to inflammation caused by the foreign object. If left untreated, this inflammation can potentially spread to the eye socket and palate, creating a dangerous situation. Surgical removal, often through an endoscopic nasal approach, is typically required when the implant cannot be naturally expelled.

Access to Oral and Maxillofacial Surgery
Active duty personnel, cadets, and Preparatory School students have access to oral and maxillofacial surgical services at the Academy hospital. TRICARE provides these services. For more complex cases, or for those not covered by TRICARE, oral and maxillofacial surgeons offer a full scope of services, from wisdom tooth removal to full mouth reconstruction utilizing dental implants. Oral surgeons are dedicated to providing a stress-free experience.
