M26.213
Malocclusion, Angle's class III
Clinical Classification Guidelines
Inclusion Terms
- Mesio-occlusion
Medical Intelligence & Overview
Malocclusion refers to the misalignment of teeth when the jaws are closed, affecting how teeth fit together. Among various types, Angle's Class III malocclusion, also known as mesio-occlusion, is characterized by the lower teeth protruding beyond the upper teeth. This condition can impact bite function, facial appearance, and oral health, making it important to understand its features, causes, and potential treatments.
Causes & Symptoms
Clinical Causes: Genetic factors influencing jaw and tooth development Inheritance of facial bone structure leading to a protrusive lower jaw Discrepancies in jaw size or shape, such as mandibular prognathism Prolonged thumb-sucking or pacifier use during childhood Early loss of deciduous teeth impacting alignment Environmental influences that affect facial growth Asymmetries in the maxillary and mandibular development
Key Symptoms: Pronounced protrusion of the lower jaw Upper front teeth may appear underdeveloped or receded Difficulty chewing or biting properly Speech issues, such as lisping or distorted sounds Facial asymmetry or imbalance in profile Increased likelihood of tooth wear or trauma due to misalignment Persistent open bite or crossbite in some cases
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough clinical examination by a dental orthodontist, including an assessment of the bite, jaw alignment, and facial symmetry. Imaging techniques, such as X-rays and cephalometric radiographs, help evaluate the skeletal relationship between the jaws and teeth. Dental impressions or digital scans are used to create models for detailed analysis and treatment planning.
Treatment Protocols: Orthodontic braces to shift teeth into better alignment Functional appliances designed to modify jaw growth in growing patients Extraction of certain teeth to reduce crowding and improve alignment Orthognathic surgery to reposition jaws in severe cases Bone grafting or other surgical procedures to correct jaw discrepancies Continued monitoring during growth phases to ensure stability
