In cases where all of the teeth need to be removed and replaced with dentures, an overdenture can help stabilize the denture so it is more comfortable. Traditional dentures are often bulky and move around while eating or talking. Thus if some implants can be placed in the mouth, the denture can snap into these implants to make it much more comfortable.
Traditionally, 6 implants are needed in the upper jaw and 4 implants are needed in the lower jaw to achieve optimal results. However, your bone levels must first be addressed to determine if adequate bone is present. When teeth have been missing for a long time, the jawbone shrinks. Thus there may be a need for bone augmentation procedures or less implants will be placed.
The implants can be placed at the same time when the teeth are taken out or after the denture has been made. Your dental surgeon at PerioLife will make the best recommendation for you at your consultation.
Whether the implants are placed at the time of the dental extractions or once all of the teeth have already been removed, the dental implants must heal in the jawbone for 3 months before they can be attached to the denture. Once the implants have healed, locator abutments are placed on the implants. An additional overdenture cap is placed inside the denture which can then attach to the locator abutments on the implants. This attachment has a snap sound once it attaches. These dentures can be removed at home to clean underneath. Overdentures are a great alternative to fixed hybrid dentures and greatly increase the quality of life for denture wearers.
Frequently Asked Questions
Snap-On dentures combine the advantages of dental implants and conventional dentures. They are sometimes called implant-supported dentures or overdentures. The denture is supported by metal posts implanted in the jawbone and not just by the gums thus making your dentures much more comfortable.
Depending on the number of implants you receive, treatment usually costs between $3,500 to $10,000 per arch: The $3,500 to 5,500 range is for snap-on dentures involving just 2 dental implants and an overdenture. Four implants and an overdenture typically costs between $8,000 to $12,000 per arch.
With repeated snapping in and out of the denture prosthesis, the overdenture attachments eventually wear out over time, resulting in diminished snap retention and perceived looseness of the overdenture. A typical replacement schedule is every 12 to 18 months of the caps inside the denture. This typically is a quick fix with minimal cost.
Overdentures, or snap-on dentures, offer substantially better results for patients than traditional dentures, alleviating the need for adhesives. They can bite and chew many more foods than they could otherwise, with just a conventional denture. Traditional Dentures are uncomfortable for patients as they move around.
