Rather than lying entirely on the edentulous ridge like complete dentures, removable partial dentures possess clasps of cobalt-chrome or titanium metal or plastic that "clip" onto the remaining teeth, making the RPD more stable and retentive. Disadvantages of these are that they have large palatal coverage for a small saddle. Class II RPDs are fabricated for people who are missing some or all of their posterior teeth on one side (left or right) in a single arch, and there are no teeth behind the edentulous area.

A removable partial denture may replace only the back teeth on both sides so it is called a bilateral (both sides) partial denture. Along with the lingual plate it is the most commonly used type of connector in the lower arch. Precision attachments are more esthetic than clasps, providing a better stability. They are lightweight in nature and constructed from a strong metal alloy which eliminates all the discomfort occurring due to partial denture. Within the design process (and prior to the master impression stage of denture construction), modifications may be suggested to teeth. GPT • SURVEYOR: "An instrument used in the construction of a removable partial denture to locate and delineate the contours and relative positions of abutment teeth and associated structures". Unlike Class I and Class II RPDs which are both tooth-and-tissue-borne (meaning they both clasp onto teeth, as well as rest on the posterior edentulous area for support), Class III RPDs are strictly tooth-borne, which means they only clasp onto teeth and do not need to rest on the tissue for added support. Purpose ; the preservation of that which remains and not the meticulous replacement of that which has been lost.

Because the dentist wants to be able to reproducibly relate the patient's maxilla and mandible, but the patient does not have teeth with which to establish his or her own vertical dimension of occlusion , another method has been devised to achieve this goal. If the teeth are spaced out and the patient does not wish for visible metal to be seen then an interrupted lingual plate may be used where the material is cut away where it would be visible anteriorly.

Sometimes there is no back tooth for an abutment. Disadvantages of these are that they are flexible due to distal extensions which can have adverse effects on force transmission to abutment teeth.

Removable partial dentures usually consist of replacement teeth attached to pink or gum-colored plastic bases. Thus, Class II RPDs clasp onto teeth that are more towards the front of the mouth, as well as on teeth that are more towards the back of the mouth of the side on which teeth are not missing, while replacing the missing more-back-of-the-mouth teeth on one side with false denture teeth.
