Aim of study: this report describes a patient with severe anterior mandibular dental crowding determinated by mandibular retrusion and hypercontraction of mentalis muscle. Material and methods: A 32-year-old female patient requested an orthodontic clinical examination in November 2019 having concerns about the possible loss of mandibular incisors with periodontal recessions.Results: The patient refused orthognathic surgery being treated with fixed orthodontic appliances after dental extractions necessary for dental alignment and bite correction, under the supervision of the attending periodontist and dentist. Conclusions: Even if the retrognathic mandibular position was not corrected by orthognathic surgery, the patient was very satisfied with the results of the orthodontic treatment, which improved her smile, dental and facial appearance and gave self-confidence.
