MCG School of Dentistry Quality Assurance Manual

Complete Denture Prosthodontics

General Guidelines
Complete dentures are indicated as a treatment procedure only when the prognosis for the remaining teeth is hopeless, or when all maxillary and mandibular teeth have been removed. Patients should be informed concerning the advantages and disadvantages of implant supported dentures and other implant supported prostheses that may be more attractive alternatives to conventional complete dentures.

The same guidelines apply to immediate complete dentures as to other complete dentures. The dentist has the responsibility of informing the patient of the necessity for modifying the denture at periodic intervals to compensate for the tissue changes that will occur. Planned coordination is necessary when the patient is referred to another dentist for preparatory surgery.

2.   Tissue irritation is present, tissue is inflamed or ulcerated.

Occlusion

1.   Occlusion is functional and noninterfering.

2.   The occlusal vertical dimension is within the physiological tolerance of the patient.
