Complete denture assessment
Evaluate support, retention, stability, ridge form, saliva, neuromuscular control and expectations before making a new denture.
Understand
A complete denture depends on support, retention, stability, border seal and coordinated neuromuscular control. Ridge anatomy and saliva set limits that technique cannot entirely remove.
Assess
Examine mucosa, ridges, jaw relationships, existing dentures, speech, aesthetics and expectations. Ask whether the main complaint is looseness, pain, appearance or function.
Apply
Explain likely improvements and limits before treatment. Manage pathology or trauma first, and consider whether repair, reline or replacement is the most proportionate response.
Key distinctions
Retention resists displacement away from tissues, stability resists rocking, and support resists movement toward tissues. A denture may have one property but not the others. The neutral zone, tongue control and saliva influence mandibular dentures particularly. Existing dentures reveal what the patient has adapted to, so apparently imperfect features may need cautious change.
Think through a case
A lower complete denture is loose despite repeated remakes. Ridge resorption, saliva and neuromuscular control may limit conventional retention; discuss realistic alternatives.
The distinction to remember
Do not assume a new impression alone can correct an unstable base, poor jaw relation or unrealistic expectation.

Why inspect an existing denture?

Its strengths and failures reveal design and adaptation issues.
