The denture base that extends anteriorly/ posteriorly and is supported by teeth at one end and tissue on the other end – distal extension partial dentures.
Temporary removable partial denture

It is a temporary partial denture used for a short period to fulfill aesthetics, mastication or convenience until a more definite form of treatment can be rendered.
May be used when loss of additional teeth is inevitable but immediate extraction is not advisable or desirable. Artificial teeth may be added to the transitional denture as and when the natural teeth are extracted.
