Here is my case: Lip incompetence (mentalis strain) Congenital absence of lower canines Gummy smile Procumbency of the lips Maxillary vertical excess One orthodontist recommended extraction of the upper premolars and recede the profile. This would resolve the lip incompetence and protusion. Another one said extraction would not solve the lip incompetence. He recommends two lower canine implants and considers a genioplasty and lip lift at the end of treatment. I don't know what to do.
