Which of the following soft tissue laser treatments includes a mandible procedure?

The correct choice refers to a procedure that specifically involves the tissue associated with the mandible, which is the lower jaw. A lingual frenectomy entails the removal of the frenulum connecting the underside of the tongue to the floor of the mouth. This frenulum can impact the movement of the tongue and, in some cases, may be related to issues with oral function that affect the mandible.

Understanding the context of the mandible is key here, as it indicates that the procedure directly involves the structures found below the tongue, which are closely associated with the lower jaw. The other procedures listed do not engage the mandible in the same way. For example, crown lengthening primarily deals with the gums and teeth, while a maxillary lip-tie frenectomy targets the upper lip's frenulum. Implant recovery focuses on the healing of tissues surrounding an implant site, but it does not specifically relate to a procedure on the mandible.

Overall, the unique relationship of the lingual frenectomy with the mandible makes it the right answer in this context.
