| Research Abstract |
This study investigated the variations of the lingual foramina in the canine/premolar region of the mandible (lateral lingual foramina : LLF). The frequency and location of LLF were evaluated from cone beam CT (CBCT) images and vessels were identified through macroscopic anatomical observations.
The LLFs were observed in 63% of mandibles, and average location was 9.7mm inferior to the mental foramen. In cadaver study, the arteries were identified to be submental arteries having anastomosed with the incisal branch of inferior alveolar arteries.
The possible injury of the vessels and the consective complication during implant surgery could be reduced by recognizing lingual foramina in the canine/premolar region in the preoperative imaging. The use of CBCT seemed to be critical to avoid complications.
