An RPD (Removable Partial Denture) refers to a removable prosthesis that is used to replace missing teeth. Upon evaluation and assessment by a certified dentist, he/she can recommend that the prosthesis should be made out of different materials such as thermoplastics, acrylic or a combination of acrylic and metal.
A basic RPD is made up of artificial teeth, a metal framework and an acrylic base. A chrome cobalt alloy is the most commonly used metal for the prosthesis framework. The whole device is held in place by clasps with rests offering the needed support together with some oral mucosa. The prosthesis has been designed perfectly to protect any tooth structures remaining after the missing teeth.
Keep in mind that if the RPD is poorly fitted and designed, it’s likely to cause damage to the remaining teeth and structures. The prosthesis is perfect for patients who have suffered some significant bone loss in the anterior area. Basically, it provides the much needed bulk to support the lip. It is easy to clean since you can remove it from the mouth when you need to brush or rinse your mouth.
It’s prudent to visit the dentist regularly for plaque removal to prevent gingivitis or dental caries among other oral issues. Before sleeping, you should remove the RPD thus allowing the soft tissues in your mouth to rest. It helps in mastication by properly selecting and setting up the artificial teeth. It doesn’t offer a mechanical advantage only but also improves speech, appearance and the overall smile.
It’s also perfect for maintaining a great healthy relationship between the lower and upper jaws. By restoring the centric occlusion, it’s easy to maintain the jaw and restore the former centric relation. The prosthesis also prevents tilting, drifting and teeth supraeruption by filling extra spaces with the artificial teeth.
The dentist is allowed to make a few modifications to the RPD to match the needs of the patient. Before the RPD is placed in the patient’s mouth, he/she performs proper diagnosis, offers the right treatment and rehabilitation to restore the oral cavity to its proper function.
