Pro Arch Articulator IV

Pro Arch Articulator IV

ProArch IV is an arcon-type, top end semi-adjustable articulator with an additional immediate side shift adjustable system that provides easy comprehension of patient’s natural jaw movement and excellent handling properties for precise fabrication of elaborate dental prostheses.


  • The Twin-Plate mechanism at the condylar guidance combines the benefits of both box and slot types. In denture fabrication, this mechanism prevents condylar guidance and ball from being disengaged in the eccentric position to provide an accurate occlusion.
  • Pro Arch IV type articulator has the angle adjustment structure for working side lateral condylar path (Bennett angle), as well as for balancing side lateral condylar path, that enables adequate lateral check bite registration.
  • The inverted-type adjustment feature makes the condylar path adjustment easy and accurate.
  • The angle of sagittal condylar path remains unchanged by the range of motion on this arcon-type articulator.
  • Pro Arch IV articulator is the only one of the Pro Arch series which features the immediate side shift adjustable system.
  • The Incisal Table can be selected from either the adjustable Incisal Table or resin block to suit individual cases.
  • The adjustment area of Incisal Pin has a shape of an arc centered on the Condylar Ball. Therefore, the position of the Incisal Pin and Table remain unchanged even if the distance between upper and lower jaws is changed.
  • Incisal and Condylar Guidance have sufficient adjustment range equivalent to human jaw.
  • The strong Centric Lock system ensures accurate centric registration.
  • Die-cast framework is lightweight with high precision while its robust structure is free from flexure and the resin coating provides a durable surface finish.
  • Upper and lower jaws are easily separated. Upper jaw can be opened up to 120° for easy access.


  • Individually packed with Metal Mounting Plate, Reference Indicator, Adjustable Incisal Table, Adjustable Incisal Rod, Resin Block and Incisal Rod for Resin Block.
