  1. Class IIISemi-adjustable condylar path articulators Prof. Dr. : Ahlam El-Sharkawy Head of the Prosthodontic Department Pharos University in Alexandria

  2. Semi-Adjustable Articulators Accept the following records 1-Accepts facebow transfer record to mount upper cast.

  3. 2- Accepts centric relation record tomount the lower cast.

  4. 3- Accepts protrusive records to adjust the articulator’s horizontal guidance.

  5. 4- Adjusted incisal guidance angle .

  6. Semi-Adjustable Articulators 5- The lateral condylar guidance is adjusted according to the Hanau’s formula L=H/8+12 • L = the lateral condylar path • H = the horizontal condylar path angle which is recorded from the patient.

  7. 6-Intercondylar distance fixed at 110mm

  8. Class IV Fully Adjustable Condylar Path Articulators Prof.Dr. Ahlam El-Sharkawy Head of prosthodonticdepartement Pharos University in Alexandria

  9. Fully adjustable articulator • Complex • Designed to duplicate TMJ features

  10. Fully adjustable articulators • Accept the following records: 1-Accept Face bow record to mount the upper cast.

  11. 2-Accept centric occluding relation record to mount the lower cast.

  12. Fully adjustable articulators 3-Accept protrusive record to adjust the articulator horizontal condylar angles. 4-Accept right lateral record, to adjust the right condylar angle. 5-Accept left lateral record, to adjust the left condylar angle.

  13. 6-Incisal guidance angle adjusted according to the patient .

  17. Non arcon articulator. • The condyles are located on the upper member of the articulator and the condylar Guidance on the lower member.

  18. Articulator Design • Arcon - condylar element on lower • Just like the condyles are attached to the mandible • Mechanical fossae located on the upper member just like the glenoidfossae • Non Arcon - condylar element on upper • Unlike natural anatomy • The condylar path (glenoidfossae) is located on the lower member
