A Rare Case Report of Heterotopic Ossification at Maxilla Anterior

Abstract

Aim
 
 To report a rare case of heterotopic ossification (HO) between the maxillary right central incisor (tooth #11) and lateral incisor in a 47-year-old male patient.
 
 Case Report
 
 A 47-year-old male patient presented with a painless, progressive-growing swelling in the anterior region involving the maxillary right central and lateral incisors for the past 6 months. The patient's medical history was unremarkable. Intraoral examination revealed periodontal loss with prosthetic restorations in the affected region for over 10 years. Radiographs and cone-beam computed tomography (CBCT) images confirmed the presence of HO between the maxillary teeth.
 
 Discussion
 
 HO is a rare condition characterized by the formation of bone in soft tissues. It is most commonly seen after trauma or surgery, but it can also occur spontaneously. The exact cause of HO is unknown, but it is thought to be due to a combination of factors, including inflammation, injury, and genetic predisposition.
 
 In this case, the patient's history of trauma may have contributed to the development of HO. The patient reported that he had sustained a blow to the anterior region of his mouth 10 years prior to the onset of the swelling. This trauma may have damaged the periodontal ligament, which may have led to the formation of HO.
 
 Conclusion 
 
 This case report highlights the importance of considering HO in the differential diagnosis of painless, progressive-growing swellings in the maxillary region, especially in patients with a history of trauma.
