“…de Gittins et al reported a case of the double coronoid process in a 61-year-old female on the left side of the jaw. They assumed that an error in embryogenesis was a cause for the duplication of the coronoid process [ 15 ].…”

“…There are limited cases in the literature reporting variation in the number of the coronoid process such as the bifid coronoid process. Patil et al [ 2 ], Cranin [ 12 ], Lundquist and Wege [ 13 ], Kansu et al [ 14 ], and de Gittins et al [ 15 ] reported cases of bifid/double coronoid process or second coronoid process. To date, no case of trifid coronoid process has been reported.…”

The trifid mandibular coronoid process is an uncommon finding characterized by three projections arising from the mandibular ramus instead of a single triangular coronoid process. Previous authors reported cases of the bifid coronoid process. The authors referred to them as the bifid/second/double coronoid process. This article aims to report a unique case of a trifid coronoid process incidentally detected during radiographic evaluation for implant planning. This article also emphasizes the effectiveness of cone beam computed tomography (CBCT) volume rendering as a valuable tool in demonstrating morphological variations such as the trifid coronoid process. In addition, we discussed possible etiologies for the trifid coronoid process. To the best of our knowledge, this is the first case of the trifid coronoid process.
