Deep tissue injury as possible pathogenesis of acute inflammatory swelling or cellulitis after connecting implant super-structures: a case series study

Background: Acute swelling or cellulitis may develop within a few days after placing definitive prosthesis reconnecting loose healing abutment/prosthesis, though its cause remains unclear. In this study, we propose mechanism for the underlying pathogenesis. Methods: We retrospectively reviewed symptoms and signs, onset of symptoms, recovery duration, laboratory data seven women two men (55–84 years) who exhibited acute pain around dental implants month connecting abutment/prosthesis between 2013 2021. Results: The extent varied from gingiva vestibule implant to face neck regions. persisted despite removal connected superstructure. All patients recovered three weeks symptom onset. Conclusions: Our findings suggest that rapid progress, etiology were consistent with pathogenesis deep tissue injury, which is characterized by inflammatory initiates interface bone subcutaneous progresses outward. Clinicians should be aware pressure-induced injury provide adequate treatment based on physiological process.
