Rebase: Dental Procedure Explanation

Rebase, a common dental procedure, refers to the replacement of the base material of a denture or other dental prosthetic. The base, also known as the denture base, is the foundation upon which the artificial teeth are mounted. Over time, this base can become worn, discolored, or misshapen, compromising the fit and function of the denture.

The rebase process involves completely removing the existing base material and replacing it with a new, updated base. This is done to restore the denture's structural integrity, improve its comfort and fit, and ensure optimal oral health for the patient.

The rebase procedure typically begins with a thorough examination of the existing denture by a licensed dental professional, such as a dentist or prosthodontist. During this assessment, the dentist will evaluate the condition of the base, the fit of the denture, and any related oral health concerns.

If the dentist determines that a rebase is necessary, the process will involve the following steps:

1. Impression Taking: The dentist will take a new impression of the patient's oral cavity, capturing the current shape and contours of the gums and surrounding structures. This impression will serve as the basis for the fabrication of the new denture base.
2. Base Removal: The existing denture base material will be carefully removed, ensuring that any remaining adhesive or material is completely cleaned from the surface of the artificial teeth.
3. New Base Fabrication: Using the new impression, the dental laboratory will fabricate a new denture base that precisely fits the patient's oral anatomy. This base may be made from a variety of materials, such as acrylic resin or thermoplastic polymers.
4. Teeth Placement: Once the new base is ready, the existing artificial teeth will be carefully positioned and securely attached to the new base, ensuring a seamless and natural-looking result.
5. Fitting and Adjustment: The dentist will then place the newly relined denture in the patient's mouth and make any necessary adjustments to ensure a comfortable and proper fit. This may involve minor grinding or polishing of the denture base or teeth.

Rebasing a denture offers several important benefits for the patient:

• Improved Fit and Comfort: As the gums and supporting structures in the mouth change over time, the fit of a denture can become compromised. A rebase ensures that the denture base closely matches the current contours of the patient's mouth, providing a more comfortable and secure fit.
• Enhanced Oral Health: A well-fitting denture helps to maintain the health of the gums and underlying bone structure. By addressing any issues with the denture base, a rebase can help prevent the development of sore spots, irritation, or other oral health problems.
• Restored Appearance: Over time, denture bases can become discolored, worn, or misshapen, which can detract from the natural appearance of the denture. A rebase allows for the replacement of the base material, restoring the denture's aesthetic appeal and giving the patient a more confident, natural-looking smile.
• Extended Denture Lifespan: By addressing issues with the denture base, a rebase can significantly extend the overall lifespan of the denture, saving the patient the cost and inconvenience of having to replace the entire prosthetic.

While a rebase is a common and effective solution for many denture-related issues, there are a few important considerations to keep in mind:
 

• Cost: The cost of a rebase can vary depending on the complexity of the procedure and the materials used. In some cases, the cost may be comparable to that of a new denture.
• Rebasing vs. Relining: In some instances, a denture may only require a relining, which involves the addition of a new base material to the existing denture base. This is a less extensive procedure than a full rebase.
• Alternatives to Rebasing: For patients who are unhappy with the fit or appearance of their dentures, alternative options may include the fabrication of a new denture or the consideration of dental implant-supported prosthetics.

Ultimately, the decision to rebase a denture will be made in consultation with a licensed dental professional, who can evaluate the patient's specific needs and recommend the most appropriate course of action.
