3 Articulator

2

The SAM® 3 articulator is supplied with a uniqueCentric locking device and condylar element covers .The newly designed rigid ON-OFF Centric lockingmechanism keeps the articulator locked in an abso-lute machine Centric position and the condylar ele-ment covers keep the articulator together in all eccen-tric positions .

SAM® 3 (ART 500) is an arcon type articulator withthe same basic dimensions as the SAM

®2 "P" but

without a cross bar between the condylar posts . Thisnew design provides better viewing and access tothe casts from the rear of the articu-lator.

The SAM® 3 articulator was designed and manu-factured using state of the art CAD/CAM . All metal-lic surfaces receive a special hard coat anodizingprocess . This metal treatment procedure is the bestand only way to attain and maintain the high level ofprecision found in all SAM® instru-mentation.

Using either SAM ® precision mounting plates or theAXIOSPLIT® matrix mounting plate system, dentalcasts mounted on one SAM® 3 articulator transfer toother SAM® 3 or SAM® 2P articulators without sig-nificant clinical errors .

The SAM

®

Articulator System gives the dental profes-sion the complete instrumentation solution or allphases of dentistry with a minimum of equipment .Dental professionals now have an instrumentationsystem with precision, reliability and versatility whichfunctions under all conditions .

Programmable curved condylar pathways andcurved Bennett guidance inserts, developed fromresearch with the SAM AXIOGRAPH, coupled withthe universal incisal table makes the SAM articulatorsystem fully adjustable .

Several versions of incisal tables are available forSAM® 3 articulators, flat and adjustable . The Flat Inci-sal Table (ART 275) is standard on ART 500 . The Uni-versal Incisal Table (ART 260), supplied with ART550, simulates the anterior guidance of the patient .This incisal table can be set for a protrusive or latero-trusive angulation from 0 to 80 degrees . In addition,the table can be set for a rotation angulation from 0to 60 degrees .

SAM® Incisal Tables

Data from manually derived calculations or the AXIO-COMP® computer orograms provide information forsetting the Universa Incisal Table . An optional GreenFlat Incisal Table (ART 272) is used for customizinganterior guidance using acrylic resin and informationfrom articulator mounted casts .

Note: Incisal Pin Scale has been offset for betterviewing of the millimeter graduation lines .

Universal Incisal Table attachment procedure :

1 . Set incisal pin to zero .2 . Attach incisal pin to the lower member of the artic-

ulator, fully seated in the slot and tighten in place .3 . Set incisal table to 0 degrees for the horizontal

rotation angle and to 80 degrees for the protrusiveangle .

4 . Attach incisal table to upper member of the articu-lator with the protrusive angulation positionedanteriorally. Lightly tighten incisal table thumbscrew to allow for antero-posterior adjustment .

5 . Move the incisal table posteriorally so that the tipof the incisal pin touches inclined anterior area ofthe incisal table surface simultaneously with the flatsurface of the incisal table. Tighten the thumbscrew .

6. Check that movable portion of the incisal tablerotates easily from 0 to 80 degrees and is still incontact with the incisal pin .
