4.  IORs
 Minimize intraoral adjustment of fixed prosthesis
 Minimise chair side time and cost.
 Provide high-quality fixed restorations.
 A clinician’s ability to relate and mount casts accurately will
have a greater impact on the quality of a restoration than the
programming of an adjustable articulator

19.  1.5mm opening with inverted cone bur

21.  No need of inter-occlusal recording material(IORM).
 Improper fit of casts into inter-occlusal record avoided.
 Prevents improper condyle position because of loss of
proprioception
 Economical

records. J Prosthet Dent 1983;50:558-60.

22.  A natural abutment tooth is necessary.
 Instability due to narrow centric stop.
 Wide enamel island results in inaccurate interocclusal
records

23.  Blunting the tip of enamel island
 Avoid contact of tray with enamel island
 Cautious retrieval of cast

24.  Enamel island acts as
 A substitute for IORM’S
 Third point of reference
 Ensures stability
