The torus mandibularis ( Latin : torus "bulge", pl. Tori ; mandibula "lower jaw") is an exostosis (bony bulge) of the lingual surface of the lower jaw above the attachment line of the mylohyoid muscle at the level of the premolars and usually occurs on both sides.
etiology
The etiology of the tori is unclear. Possible causes are bruxism , continued bone growth, genetic factors, or environmental factors. The prevalence of tori is 12.3% to 26.9% with an average occurrence in the fourth decade of life. Tori mandibulares have an increased prevalence in men. The tori tend to grow continuously, are usually nodular and usually less than 2 mm in size. They can be unilateral or bilateral. Tori usually remain asymptomatic. Often the tori appear together with the torus palatineus .
dentures
Patients with poorly fitting dentures can have more pressure points. It is usually not necessary to remove tori. The most common reason for removal is interference with a denture in the lower jaw or psychological reasons (sensation of a foreign body, carcinophobia ).
