Maxillary Major Connectors
Connectors
A- Major Connectors
– Is a unit of the partial denture that connects the parts of the prosthesis located on one side of the arch with those on the opposite side.
• Functions of a Major Connector
Unification (Union, Fusion):
Partial denture acts as one unit.
Connects various parts.
Stress Distribution:
Distributes functional loads to both teeth & mucosa.
Cross-Arch Stabilization (Counter leverage):
Bracing elements on one side of the arch providing stability to the other.
➤ Requirements of a Major Connector
Must be properly located in relation to gingiva and moving tissue.
Must not impinge on the marginal gingiva.
Cover no more tissue than is necessary.
Rigidity
• To Increase Rigidity:
Use a more rigid alloy
Chrome-cobalt > gold alloys; cast > wrought.
Shape
1/2 round > 1/2 pear shaped > flat bars.
Increase the bulk as the length increases.
Corrugate linguo-plate or rugae areas.
Does not contribute to retention or trapping of food particles.
Bony and soft tissue should be avoided during placement and removal.
➤ Major Connectors are Divided into:
A- Mandibular Major Connectors.
B- Maxillary Major Connectors.
B- Minor Connectors
