• FPD = Fixed Partial Denture, bridge
• Abutment = tooth to which a bridge or partial denture is attached
• Framework = structure connecting to abutments in order to carry pontic
• Retainer = part of the bridge framework which fit the restoration (crown, inlay) of abutment and is connected with this restoration
• Pontic = artificial tooth as a part of a bridge
• Connector = part of the bridge framework attaching pontic to retainer. Connectors can be rigid or norigid (male-female-locking arrangements)
• Span = space between natural teeth that is to be filled by the bridge
• Saddle = is the area of the edentulous ridge over which the pontic will lie
• Pier = abutment tooth supporting two pontics, each pontic being attached to a further abutment tooth
• Unit = when applied to bridgework, means either retainer or a pontic. A bridge with two retainers and one pontic would therefore be a three-unit bridge
• Member = when applied to bridgework, means replaced tooth. A bridge replacing two teeth would therefore be a two-member bridge
• Substructure = bundle of reinforcement fibers
• Suprastructure = structure creating anatomical shape and contour of pontic over the bridge framework
• Slot/Box = rectangle hollow of the hubic shape in the distal or mesial side of the teeth, no shoulders
• Groove = long shallow semicircular channel which lies on the oral side on the tooth; used mostly for incisors
• Inlay = restoration, which lies inside the cusp tips of a tooth (MO: mesio-occlusal, MOD: mesio-occlusal distal) – intraconal restoration
• Onlay = more extensive restoration that cover one or more cusps of a tooth, clasiffied as smallest extracoronal restoration
• Complete crown = restoration covering the entire anatomy of a tooth´s clinical crown
• Partial crown = restoration covering more than half but not all of the tooth´s clinical crown. A partial crown is named according to the fractional amount of the clinical crown it covers (three-quarters, four-fifth, seven-eights)

Types of Bridge Retainers

• Complete crown
• Partial crown
• Onlay
• Inlay
• Groove
• Slot
• Non invasive/extracoronal – wings
• Non invasive/extracoronal – splint (Rochette´s splint)
  

Biomechanics of the Bridge Framework

Primary roles of bridge framework are:

• To carry the pontic
• To shift the load applied to pontic during mastcation to abutment teeth.

Typology of Bridges Made from Dentapreg™

Retentions

Extracoronal retentions:

• Complete crown
• Partial crown
  

Intracoronal retentions with reduced invasivity

• Onlay
• Inlay
• Slot
  

Extracoronal non invasive retentions

• Wing
• Splint (Rochette´s Bridge)

Symetry of Retentions

• Bridge with one type of retention (uniform retention)
• Bridge with two types of retention (combined retention)

Durability

• Permanent bridges
• Semipermanent bridges
• Provisional bridges

Reasons of Fracture of Removable Dentures and Appliances

• Extreme loading during chewing process
• Long-time bending as a result of chewing process
• Failure on interphase between removable denture or appliance and resin teeth
• Fall down of removable denture or appliance
