Background:
Dental implants allow functional and aesthetic reestablishment. Titanium (Ti) implants emerge as the preferred choice because Ti is considered an inert material, highly resistant to corrosion. However, virtually no material can be considered universally biocompatible and this includes titanium.
Purpose:
To report an unusual presentation of inflammatory reaction after a Ti dental implant.
Materials And Methods:
The patient presented to a dermatology clinic to evaluate lesions on her face. She reported the placement of dental implants 2 years earlier, one of which evolved with inflammatory signs and instability a few days after the procedure. As anti-inflammatory and antibiotic therapy were fruitless, after 3 months the implant was removed, but the inflammation persisted. On physical examination, painful erythematous-papule-nodular lesions were found on the left mandibular and submandibular region.
Results:
Culture tests for microorganisms were negative and histopathological examination revealed a chronic fistula with a foreign body reaction. Using X-ray fluorescence, Ti particles were found along the fistula wall.
Conclusions:
Professionals should be aware of complications arising from dental implants, including Ti implants. Detailed anamnesis and laboratory investigation can assure diagnosis for specific therapeutic approaches.
