22. INLAY A fixed intracoronal restoration; a dental restoration made outside of a tooth to correspond to the form of the prepared cavity, which is then luted into the tooth Inlay may be used as a single tooth restorations for proximo-occlusal or gingival lesions with minimal to moderate extensions. They may be made up of gold alloy or ceramic material. Inlays are similar to fillings but the entire work lies within the cusps on the chewing surface of the tooth .
23.
24. ONLAY A restoration that restores one or more cusps and adjoining occlusal surfaces or the entire occlusal surface and is retained by mechanical or adhesive mean It is used for restoring more extensively damaged posterior teeth needing wide mesio-occluso-distal restorations. All Ceramic Onlay

27. PARTS OF FIXED PARTIAL DENTURE RETAINER ABUTMENT PONTIC CONNECTOR
28. RETAINER Any type of device used for the stabilization or retention of a prosthesis Positioned at margin - less susceptible to caries or recurrence of caries Rigidity – withstand the requisite load Functional adaptation and protect the tooth against its fracture Least destroys the cervical marginal ridge
29.
30. Pontics An artificial tooth on a fixed dental prosthesis that replaces a missing natural tooth, restores its function, and usually fills the space previously occupied by the clinical crown Pontics
31.
32. ABUTMENT A tooth, a portion of a tooth, or that portion of a dental implant that serves to support and/or retain a prosthesis
33. Connectors Fixed dental prosthodontics, the portion of a fixed dental prosthesis that unites the retainer(s) and pontics Types- -Rigid connectors -Non rigid connectors -tenon mortise connectors -loop connectors -split pontic connectors -cross pin and wing connectors
35. Loop connectors Loop connectors are used for when existing diastema is to be maintained in the planned fixed prosthesis T he connector consists of a loop on the lingual aspect of the prosthesis that connects adjacent retainers and /or pontics
