Understanding Denture Rebases

Denture rebasing is a dental procedure designed to improve the fit and function of existing dentures. Over the years, natural changes occur in the jawbone and gum tissues, impacting the original fit of dentures. This can lead to discomfort, difficulty in chewing, and even aesthetic concerns. A denture rebase involves replacing the entire acrylic portion of the denture while retaining the original denture base. This ensures a renewed fit and enhanced functionality.

Recognizing the signs calling for denture rebases is essential. Below, we have highlighted a few indicators that should prompt consideration for this important dental procedure.

Looseness and Discomfort

  • If dentures feel loose or cause discomfort while eating or speaking, it may indicate a change in the fit. A rebase can address these issues, providing a snug and comfortable fit.

Irritation or Sore Spots

  • Persistent irritation, sore spots, or redness on the gums may be signs of an ill-fitting denture. A rebase can eliminate these issues, promoting better oral health.

Changes in Speech

  • Difficulty in speaking or changes in speech patterns can be attributed to denture movement. Rebasing helps stabilize dentures, improving speech clarity.

Visible Wear and Tear

  • Visible signs of wear and tear on the denture material, such as cracks or chips, indicate the need for refurbishment through a rebase to maintain optimal functionality.

The Denture Rebase Process

The process for this procedure is an efficient one, with the timeframe depending on individual circumstances. While it is generally completed within a few appointments, the exact duration can vary based on factors such as the extent of adjustments needed and specific requirements. This personalized approach ensures that the procedure is tailored to each individual, striking a balance between thoroughness and timely completion. In this section, we will look at the steps involved in this process.

Assessment and Impression

  • The process begins with a comprehensive assessment of the existing dentures and the oral tissues. An impression is then taken to capture the current shape and contours of the mouth.

Acrylic Replacement

  • The acrylic portion of the denture, which rests against the gums and supports the artificial teeth, is replaced. The new acrylic is carefully crafted to ensure an improved fit and enhanced comfort.

Adjustments and Refinements

  • Once the new acrylic is in place, the denture is adjusted to achieve the ideal fit. The dental professional ensures that the bite is accurate and that the dentures sit comfortably in the mouth.

Final Polishing

  • The rebased dentures undergo a final polishing to achieve a smooth and aesthetically pleasing finish. This step contributes to both comfort and the overall appearance of the dentures.

Benefits of Denture Rebases

There are numerous benefits to denture rebases, extending beyond improved fit. In this section, we will explore the various advantages that this transformative procedure offers.

Improved Comfort

  • A well-fitted denture through a rebase eliminates discomfort, allowing individuals to wear their dentures with ease throughout the day.

Enhanced Stability

  • Rebasing restores the stability of dentures, preventing slippage or movement, and facilitating improved functionality during activities like eating and speaking.

Optimal Oral Health

  • By addressing issues like sore spots and irritation, a rebase contributes to optimal oral health, reducing the risk of complications associated with ill-fitting dentures.

Extended Lifespan

  • Denture rebases can extend the lifespan of dentures by revitalizing the acrylic portion, delaying the need for complete denture replacement.
