Complete Denture
Dental RCM Glossary
A removable prosthesis that replaces all teeth in an entire dental arch, resting on the edentulous ridge and surrounding soft tissues for support and retention.
A complete denture is a removable prosthetic appliance designed to replace all natural teeth in either the maxillary or mandibular arch. It relies on the underlying alveolar ridge, palatal tissue (in the case of upper dentures), and the border seal created by the denture flanges for retention and stability. Complete dentures are fabricated through a multi-step process that includes preliminary and final impressions, jaw relation records, try-in appointments, and final delivery with adjustments. Each of these steps represents chairtime and lab costs that factor into the overall case profitability.
When handling claims, complete dentures are coded under CDT codes D5110 (maxillary) and D5120 (mandibular) for conventional complete dentures, and D5130 (maxillary) and D5140 (mandibular) for immediate complete dentures. The distinction between conventional and immediate dentures is important for claim submission. Immediate dentures are placed on the same day teeth are extracted, while conventional dentures are fabricated after the extraction sites have healed. Some insurance plans cover both types but may apply the benefit toward the patient's prosthodontic frequency limitation, meaning the patient may not be eligible for a replacement denture for five to ten years depending on the plan terms.
Denture-related claims are among the most common targets for frequency limitation denials in dental billing. Most plans allow a new complete denture only once every five to eight years, and some require documentation that the existing denture is no longer serviceable before approving a replacement. Practices should verify the patient's prosthetic history and confirm the plan's replacement clause before starting treatment. Relines (D5710, D5711, D5720, D5721) and repairs (D5511, D5512) are often covered between replacement cycles and can serve as interim solutions. Proper treatment sequencing and proactive benefit verification help practices avoid situations where a patient receives a new denture only to have the claim denied due to a frequency limitation.
Why It Matters for Dental Practices
Complete dentures involve multiple billable visits from impressions through delivery, and insurance plans often impose waiting periods, frequency limitations, and replacement clauses that directly affect reimbursement timing.
Example
A patient with a failing upper dentition requires full-arch extractions followed by an immediate complete denture. The practice bills D5130 for the immediate denture at delivery and later D5110 when the definitive denture is fabricated after tissue healing. The billing team confirms the plan's replacement clause allows a new denture within the benefit year since the immediate denture is considered a transitional prosthesis by some carriers.
