Removeable partial denture
01
Summary
is
a dental prosthesis that replaces the lost natural dentition and associated structures of maxilla or mandible;it can be removed conveniently from the mouth by the patient.
The denture base supports artificial teeth and effects the transfer of occlusal forces to supporting oral structures.
Connection：Arrange artificial teeth ,connect denture parts into a whole.
01 Maintains components in their planned
positions.
02 Maintains established occlusal
relationships by preventing settling of the denture.
03 Prevention of food impaction and
Repair deficiency：Repair of alveolar bone, jaw and soft tissue defects
Transfer occlusal force：Bear, transfer and dispersion of artificial teeth occlusal force

Rest
Any unit of a partial denture that rests on a tooth surface to provide vertical support is called a rest.
Retention and stabilization：Prevent rotation and warping of denture
A major connector is the unit of partial denture that connect the parts of the prosthesis located on one side of the arch with those on the opposite side.
sometimes ,it can be used as restoration of occlusion
Its width and thickness should meet the requirements of materials. The width is 1/3 of molars' dental diameters or 1/2 of premolars. The length is usually 1/4 of the molar’mesiodistal or 1/3 of the premolar.The thickness is about 1~1.5mm.
Retainer
is the part of removable partial denture to resist dislocation and obtain retention, support and stability
Direct retainers
The direct retainer resists the displacement of the denture away from the base and
