Fixed Movable Partial Denture

Fixed movable partial denture is sometimes called as fixed free partial denture. It is a partial denture where the pontic is rigidly supported on one side, usually the distal end by one or more abutment teeth. On the other side, the abutment will contain a precision abutment, a stress breaking device. This will allow a small degree or limited movement between the rigid component and the other abutment tooth or teeth. This movable joint will give full support to the pontic against vertical occlusal forces, and will allow limited movement in response to lateral forces.

The advantage of fixed movable dental bridge is that both retainers do not need to be parallel.



Fixed movable partial denture is indicated where abutment teeth are tilted in relation to each other and the tooth preparation needed to make them parallel would require too much reduction and highly destructive to the abument teeth. It is also indicated for long span bridgework. The use of attachments allows for the separation of large units into several smaller sections or segments. Read: Segmented Fixed Partial Denture

Segmented dental bridge has a fixed-fixed partial denture segment and a fixed movable partial denture segment.

Divergent abutments are prepared conservatively and independently. Consideration is given to the placement of the movable joint. The segments of this type of fixed partial denture can be cemented separately.

The movable joint for fixed movable partial denture can be precision or semi-precision. Precision has an improved fit while semi-precision allows more flexibility. Read: Attachments for Bridge Segmenting

Usually the distal abutment carries the major retainer but this can also be reversed.
