What Is the Difference Between Dentures and Overdentures?
One type of implant-supported denture that I place is called an overdenture. This dental implant creates a gum-supported base onto which a removable denture can be placed; overdenture implants are typically used for the lower teeth. But what are the fundamental differences between standard dentures and overdentures, and why might someone choose an implant overdenture over a full or partial traditional denture?
Understanding Standard Dentures
For a standard denture to be fitted, the patient must first have any remaining teeth extracted. Sometimes, dentures are cemented onto the gums, while other times they are held in place with removable adhesive. However, without the support of existing teeth, the gum ridge can collapse over time, leading to a sunken appearance in the mouth. As the gum ridge flattens, traditional dentures can become loose due to tongue movement and other factors, making them a nuisance that can hinder basic functions like eating and speaking. These disturbances can significantly impact one’s quality of life.
The Advantages of Implant Overdentures
Fortunately, potential denture patients now have an alternative option by choosing an implant overdenture. The process begins with surgically placing implants into the jawbone, which serve as anchors for the overdenture. Typically, overdentures are used for the lower teeth, as traditional dentures tend to be less stable in the lower arch due to the U-shaped ridge, lack of osmotic pressure, and tongue movement.
Once the implants are placed, I will use locators (ball-and-socket arrangements) to securely attach the removable prosthetic denture to the implants. These locators ensure that the overdenture remains stable, eliminating the inconvenience of sliding or shifting in the mouth.
In summary, while traditional dentures can offer a functional solution for missing teeth, implant overdentures provide enhanced stability, comfort, and quality of life for patients.
The Advantages of Overdentures
Overdentures offer significant benefits over conventional dentures. Many patients choose implant overdentures because they enhance retention, stability, and comfort. Unlike traditional dentures that can slide around the gums, overdentures are securely anchored to implants, allowing patients to maintain their dietary health without avoiding chewy or hard foods.
Additionally, implants help prevent facial contour deterioration, improving both physical appearance and mental well-being. Traditional dentures can lead to facial bone loss and jaw collapse, but implants integrate with the gum and bone, providing essential support and preventing further deterioration.
Overall, implant overdentures are a more comfortable, durable, and healthy option, allowing patients to enjoy a varied diet, speak and smile with confidence, and maintain their natural appearance.
