If all of your upper or lower teeth are missing, the use of dental implants to stabilise your upper or lower denture will help improve your chewing ability and quite honestly, your quality of life. Traditionally, the maximum force that can be generated with an upper and lower denture is only roughly 20% that of natural teeth. However, when supported by implants, your chewing ability will improve exponentially. Complete lower dentures are typically fabricated for aesthetics more than function, but the addition of implants will help support and stabilize your denture, dramatically improving your chewing ability and comfort. Additionally, dental implants will prevent your bone from continuing to shrink, extending the lifetime of your denture.
When teeth are replaced with conventional dentures rather than dental implants, a natural attrition of the jawbone occurs. This ongoing deterioration of the ridge can lead to ill-fitting dentures and sores over time. When this occurs, options to restore the denture fit are denture relines, denture rebase, or construction of a new denture. Additionally, placement of dental implants to facilitate an overdenture restoration will aid in minimizing future ridge resorption and improve denture stability.
To facilitate better retention (“less rocking and moving”) of your lower denture, your dentist may recommend placing 2-4 implants to anchor your denture to. Once the implants have healed within your bone, they are uncovered to allow for the placement of retentive abutments. The retentive abutments are designed to fit into the precision attachment within the denture, creating a secure fit. This will help stabilize your denture and will allow you to chew and speak with far less movement of your lower denture.
Fully edentulous patients (“patients without any teeth”) can benefit from the placement of multiple implants connected to each other with a retentive bar. The implants are placed at appropriate distances from each other and the retentive bar is secured to the restoration (“the fixed denture”). The denture is designed with retentive clips that securely hold your denture in place. This will help stabilize your denture and will allow you to chew and speak with far less movement of your lower denture.
