[Labial incompetence and maxillodental dysmorphosis].

Area of Science:

• Dentistry
• Orthodontics
• Oral and Maxillofacial Surgery

Background:

• Labial incompetence is often misattributed to nasal airway obstruction.
• It is primarily a manifestation of underlying maxillodental dysmorphism (MDD).

Purpose of the Study:

• To define labial incompetence and differentiate it from nasal dyspermeability.
• To outline the diagnostic features and pathogenic factors of MDD causing labial incompetence.
• To describe orthodontic and surgical treatment principles for restoring labial competence.

Main Methods:

• Clinical and paraclinical evaluation of patients with labial incompetence.
• Analysis of alveolodental and bony dysplasias contributing to the condition.

Main Results:

• Labial incompetence is confirmed as a symptom of MDD.
• Various dental and skeletal abnormalities are identified as causes.
• Treatment strategies focus on functional articulation restoration.

Conclusions:

• Accurate diagnosis distinguishing MDD from nasal issues is crucial.
• Addressing skeletal and dental anomalies is key to resolving labial incompetence.
• Restoring proper articulation leads to improved labial competence.
