What Is an Interim Denture?

An interim denture — also called a transitional or provisional denture — is a temporary removable prosthesis designed to be worn for a defined, limited period while a more permanent restoration is being planned, fabricated, or awaited. It is not intended as a long-term solution but plays an important role in comprehensive dental treatment.

When Is an Interim Denture Used?

Clinical Situation Role of Interim Denture

During implant osseointegration Maintains appearance and function while implants heal (3–6 months)

After extractions, before final denture Transitional use during healing

During full-mouth reconstruction Maintains function and aesthetics between treatment phases

Evaluating a new bite or vertical dimension Tests a new jaw position before committing to final restorations

Waiting for insurance approval Functional prosthesis during administrative delays

Staged treatment planning Placeholder while remaining treatment is completed

How Is an Interim Denture Different from a Permanent Denture?

Feature Interim Denture Permanent Denture

Purpose Temporary — defined timeframe Long-term use

Materials Simplified acrylic Higher-quality materials

Precision of fit Good — not optimized Optimized for long-term comfort

Durability 6–18 months typical use 5–10 years

Cost Lower Higher

Role Placeholder and diagnostic Definitive restoration

The Diagnostic Value of an Interim Denture

In complex cases, an interim denture serves an important diagnostic function:

• Allows Dr. Kim to evaluate whether a proposed bite position is comfortable

• Gives the patient time to adapt to a new vertical dimension

• Identifies any adjustments needed before investing in final restorations

• Provides a blueprint for the permanent prosthesis

This is particularly valuable in full-mouth reconstruction cases where significant changes to the bite are planned.

What to Expect

• Fabrication is typically faster than a permanent denture

• Fewer appointments required

• The interim denture is adjusted as needed during the transition period

• A clear timeline and treatment plan will be established so you know exactly when the final restoration will be completed

Important Note

Wearing an interim denture beyond its intended timeframe is not recommended. As the gums and bone change, a poorly fitting interim denture can cause:

• Sore spots and tissue irritation

• Accelerated bone resorption under an ill-fitting base

• Difficulty adapting to the final prosthesis

Dr. Kim will monitor your interim denture at every visit and keep your treatment moving forward on schedule.
