1-Accepts facebow<br />
transfer record to mount<br />
upper cast.
2- Accepts centric relation record to<br />
mount the lower cast.
3- Accepts protrusive records to adjust<br />
the articulator’s horizontal guidance.
4- Adjusted incisal guidance angle .
5- The lateral <strong>condylar</strong> guidance is adjusted<br />
according to the Hanau’s formula<br />
L=H/8+12<br />
Where; L = the lateral <strong>condylar</strong><br />
<strong>path</strong><br />
H = the horizontal <strong>condylar</strong> <strong>path</strong><br />
angle which is recorded from the<br />
patient.
6- Inter<strong>condylar</strong> width fixed at 110mm
Complex<br />
Designed to duplicate TMJ features
Accept the following records:<br />
1-Accept Face bow record to mount the upper<br />
cast.
Indirect jig with record base on<br />
articulator
2-Accept centric occluding relation record<br />
to mount the lower cast.
3-Accept protrusive record to adjust the<br />
articulator horizontal <strong>condylar</strong> angles.<br />
4-Accept right lateral record, to adjust the right<br />
<strong>condylar</strong> angle.<br />
5-Accept left lateral record, to adjust the left<br />
<strong>condylar</strong> angle.
6- Inter-<strong>condylar</strong> distance adjusted according<br />
to the patient.
Depends on the location of the condyle<br />
whether in the upper or lower member of<br />
the articulator:<br />
1- Arcon articulator.<br />
2- Non Arcon articulator.
The condyles are located on the lower<br />
member of the articulator and the <strong>condylar</strong><br />
guidances are on the upper member.<br />
AR=Articulator<br />
Con= Condyle.
The condyles are located on the upper<br />
member of the articulator and the <strong>condylar</strong><br />
Guidance on the lower member.
Arcon - <strong>condylar</strong> element on lower<br />
• Just like the condyles are attached to<br />
the mandible<br />
• Mechanical fossae located on the<br />
upper member just like the glenoid<br />
fossae<br />
Non Arcon - <strong>condylar</strong> element on<br />
upper<br />
• Unlike natural anatomy<br />
• The <strong>condylar</strong> <strong>path</strong> (glenoid fossae) is<br />
located on the lower member
