Name of the Condition

• Insufficient interocclusal distance of fully erupted teeth (ridge)
• Also known as reduced occlusal vertical dimension (OVD) or decreased bite space.

Summary

• Insufficient interocclusal distance refers to a decreased space between the rows of teeth when the mouth is closed and the teeth are fully erupted. This can lead to discomfort, improper jaw function, and other dental complications.

Causes

• Causes can include dental wear over time, improper dental restorations, loss of teeth without replacement, or compromised jawbone support due to conditions like osteoarthritis.

Risk Factors

• Age (older individuals are more prone due to natural wear), gum disease, poor oral hygiene, and a history of orthodontic issues or dental trauma.

Symptoms

• Symptoms may include jaw pain, headaches, tooth wear, difficulty chewing, changes in facial appearance, and increased sensitivity in teeth.

Diagnosis

• Diagnosed through dental examinations, radiographic imaging, and assessment of jaw function and occlusal relationships by a dentist or orthodontist.

Treatment Options

• Treatment typically involves dental restoration procedures such as crowns, bridges, or dentures to restore the appropriate occlusal height. In some cases, orthodontic treatment or surgery may be required to align the bite properly.

Prognosis and Follow-Up

• With appropriate treatment, the prognosis is generally good. Regular dental follow-up is important to monitor bite changes and maintain occlusal stability over time.

Complications

• Untreated, this condition may lead to temporomandibular joint disorder (TMJ), severe tooth wear, difficulties in speech and chewing, and increased tooth sensitivity or damage.

Lifestyle & Prevention

• Maintaining good oral hygiene, regular dental check-ups, using mouth guards if necessary, and promptly addressing dental issues can help prevent the reduction of interocclusal distance.

When to Seek Professional Help

• Seek professional help if experiencing persistent jaw discomfort, tooth wear, or changes in bite that affect eating or cause discomfort.

Additional Resources

• The American Dental Association (ADA) provides extensive resources on dental health.
• The Academy of General Dentistry (AGD) offers support and information about dental occlusion and related issues.

Tips for Medical Coders

• Ensure accurate coding by confirming the condition involves fully erupted teeth and specific reference to occlusal issues.
• Be cautious not to confuse with conditions involving tooth eruption anomalies or unrelated jaw problems.
