Abstract
Purpose
The double coronoid process (DCP) is a very unusual feature in patient. The literature, which briefly describes just only one case. Being this a very unusual feature, the aim of the paper is to describe the finding, discuss the anatomic, radiological, and clinical characteristics of a DCP.
Methods
A 61-year-old-woman with no significant medical history, extraoral and intraoral examination was unremarkable. Following panoramic radiography (PR) for assessment of periodontal support and pre-implant planning suspicious radiopaque area in the mandibular notch on the left side was observed. Cone-Beam Computed Tomography (CBCT) and Magnetic resonance imaging (MRI) were subsequently performed.
Results
No signs and symptoms of syndromes or medical records with a relevant contribution to the DCP existence and the patient denied any type of facial trauma. CBCT image showed the structure found on the PR was indeed a DCP and it was not superimposed on the mandibular notch area, MRI was performed to investigate soft tissue components and temporomandibular joint (TMJ) or other alterations.
Conclusion
DPC is extremely rare with the only case reported in the literature within the same comparison parameters. In this case images revealed the muscles, articular surfaces and articular disc were well preserved, and no other alterations were found.
