Osseointegrated implants are now commonplace in contemporary
dentistry. However, a number of
complications can occur around
dental implants, including
peri-implantitis,
maxillary sinusitis,
osteomyelitis, and
neoplasms. There have been several
reports of a
malignant neoplasm occurring adjacent to a
dental implant. In this
report, we describe 2 such cases. One case was that of a 75-year-old man with no previous
history of malignant
disease who developed a solitary
plasmacytoma around a
dental implant in the left posterior
mandible, and the other was that of a 43-year-old man
who was diagnosed with
squamous cell carcinoma adjacent to a
dental implant in the right posterior
mandible. Our experiences with these 2 cases suggest the possibility of a relationship between implant
treatment and an inflammatory cofactor that might increase the
risk of development of a
malignant neoplasm.
