M26.59
Other dentofacial functional abnormalities
Clinical Classification Guidelines
Inclusion Terms
- Centric occlusion (of teeth) NOS
- Malocclusion due to abnormal swallowing
- Malocclusion due to mouth breathing
- Malocclusion due to tongue, lip or finger habits
Medical Intelligence & Overview
ICD-10 code M26.59 refers to a variety of dentofacial functional abnormalities that do not fall into more specific categories. These issues can affect how the teeth and jaws develop and function together, leading to misalignments and other oral health concerns. Common causes include habits, breathing patterns, and swallowing issues that influence the normal development of facial and dental structures.
Causes & Symptoms
Clinical Causes: Centric occlusion (the way teeth come together when the jaws are closed) issues that are not specified elsewhere Malocclusion caused by abnormal swallowing patterns, where swallowing does not follow typical mechanics Malocclusion resulting from mouth breathing habits, which can alter jaw and dental development Dento-facial functional disturbances due to habits such as tongue thrusting, lip pressing, or finger sucking Malocclusion linked to lip habits or persistent mouth breathing that influences jaw positioning Other functional disturbances affecting the normal alignment and occlusion of teeth
Key Symptoms: Misalignment of teeth or bite that may not be classified as specific malocclusion types Difficulty in closing the lips comfortably or maintaining proper lip closure Persistent tongue thrusting during speech or swallowing Open bite or other bite irregularities related to habits or respiratory issues Facial asymmetry or altered jaw development over time Functional issues such as speech difficulties or chewing problems
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive clinical examination by a dental or orthodontic specialist. The practitioner will evaluate the patient's bite, jaw alignment, and oral habits. Imaging such as X-rays or photographs may be used to assess skeletal and dental relationships. A detailed history of breathing patterns and oral habits is essential to identify contributing behaviors like mouth breathing or finger sucking.
Treatment Protocols: Management typically involves addressing the underlying habits and functional issues. This may include:
