When you are missing one or more teeth, the bite pressures shift in your mouth. Other teeth may begin to move to compensate for the “gap” in your bite, and you may experience shrinking of both the soft tissues and the supporting bone near your missing teeth. This can alter your physical appearance and can lead to subsequent problems with your other teeth. A partial denture keeps the underlying structures of your mouth – your gums, jawbone, facial muscles, etc. – active and engaged. It helps prevent further shifting of the other teeth in your mouth, while giving you the confidence of having a beautiful, complete smile.
Implant technology can vastly improve the patient's denture-wearing experience by increasing stability and preventing bone from wearing away. Implants can also aid retention. Instead of merely placing the implants to serve as blocking mechanism against the denture's pushing on the alveolar bone, small retentive appliances can be attached to the implants that can then snap into a modified denture base to allow for tremendously increased retention. Available options include a metal "Hader bar" or precision balls attachments.
An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
