However, in some individuals, the frenum extends to or beyond the interdental papilla. Such an aberrant or high frenular attachment compromises plaque control, orthodontic treatment, denture retention, and esthetics. Therefore, surgical correction of the high frenal attachment is recommended either by completely removing the frenum (frenectomy) or repositioning it (frenotomy). Frenectomy or frenotomy can be performed either with a surgical blade, electrocautery, or lasers. Frenectomy using a surgical blade is considered to be more invasive compared to other methods, as it involves mild-to-moderate bleeding, the formation of large surgical wounds, and the chances of scarring during healing. Hence, many modifications to the conventional frenectomy technique have been explored to provide a simpler, faster, and minimally invasive surgical approach.
