When it comes to restoring bite function and smile aesthetics lost due to missing teeth, dentures and dental implants are the primary treatment options. For some patients, a combination of the two known as implant-supported dentures is the best choice.

With implant-supported dentures, bite stress is channeled around the dental implants. Because dental implants are set in the jaw bone, which grows around the implants and anchors them, bite stress over time can affect the structure of the mandibular bone if the implants are not properly distributed and placed. The results of a new study demonstrate how the number of dental implants used, as well as their placement, may impact the success of implant-supported dentures and changes to the jaw bone.

What are Implant-Supported Dentures?

Implant-supported dentures are similar to traditional overdentures, but they are attached to and supported by dental implants, which are held in position by jaw bone that has naturally regrown and fused around the implants. Traditional dentures rest on the gums without the reinforcement of dental implants.

Implant-supported dentures can be ideal for those who are missing a series of teeth, but have sufficient healthy mandibular bone to support dental implants. Although implant-supported dentures can be used for either the upper or lower jaw, they are more often used for the lower jaw, where regular dentures otherwise have less stability.

Implant-Supported Dentures and Bite Stress

A recent study, the results of which will be published in the May 1 issue of the Journal of Biomedical Engineering, focused on the effects of bite stress on implant-supported dentures, and how the number of implants used and their placement can influence bone density. With an increased number of dental implants, the bite force applied to the dentures decreased, and the stress on the implants and underlying bone was more evenly distributed; with fewer implants, the stress on the dentures and the bone increased, and the bone density progressively decreased.

When it comes to implant-supported dentures, the “right” number of implants depends on many unique physical factors, including the number of missing teeth, and the health and density of the jaw bone. The study reinforces the importance of individualised attention when it comes to the placement of dental implants for implant-supported dentures in order to ensure effective distribution of bite force and minimize stress on the bone.
