M26.37
Excessive interocclusal distance of fully erupted teeth
Clinical Classification Guidelines
Inclusion Terms
- Excessive intermaxillary vertical dimension of fully erupted teeth
- Loss of occlusal vertical dimension of fully erupted teeth
Medical Intelligence & Overview
Excessive interocclusal distance, also known as an increased vertical dimension between the upper and lower teeth when the mouth is closed, can affect dental function and aesthetics. This condition, coded as M26.37 under ICD-10, involves an abnormal height of the occlusal (biting) surfaces of the teeth despite full eruption. It can be caused by various factors that lead to either an increase or loss of the normal vertical dimension of occlusion, impacting how the teeth come together and function.
Causes & Symptoms
Clinical Causes: Wear or attrition of teeth leading to decreased vertical dimension, resulting in a loss of vertical height Trauma or injury causing displacement or loss of teeth and subsequent changes in vertical dimension Dental restorations or treatments that alter the natural height of teeth Developmental anomalies affecting jaw and dental structure Massive tooth loss, especially if not replaced promptly, leading to a lowered vertical dimension Certain neuromuscular disorders affecting muscle tone and jaw position
Key Symptoms: Difficulty comfortably closing the mouth Increased space or gap between the upper and lower teeth when the jaw is closed Altered facial appearance with a shortened or elongated lower face Jaw pain or discomfort due to abnormal bite positioning Difficulty in chewing and speaking Tooth sensitivity or wear due to altered occlusal forces Potential temporomandibular joint (TMJ) discomfort or dysfunction
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive dental examination including visual inspection, measurement of the vertical dimension, and assessment of occlusion. Dental radiographs and bite analysis may be used to evaluate the extent of changes. Cephalometric analysis can assist in understanding skeletal relationships. A patient's dental history, including any recent restorations or trauma, helps in confirming the cause and extent of vertical dimension alteration.
Treatment Protocols: Treatment options aim to restore the natural vertical dimension and improve function. Approaches may include:
