Frenotomy, means the correction of long or large frenulum. Frenectomy is the excision of frenulum.
Frenulums are located under the tongue at lip and gum combination. When these frenulums are higher than they should be , they cause gum diseases.
Sometimes removable dentures can not stay in their places because of frenulums. To avoid such troubles incision is made on the frenulum.
The most important factor in determining the treatment is the degree of the periodontal disease caused by frenulum.
