  • 81. Mounting the Mandibular Cast www.indiandentalacademy.com
  • 82. The upper and lower frame are made parallel by aligning the top of the pin boss with the dark line which completely encircles the pin. The pin should be adjusted 3 to 5 millimeters above the zero mark to compensate for the www.indiandentalacademy.com thickness of the centric relation record used to mount the lower model.
  • 83. With the locking tabs in the locked position and the side shift guides set to the “0” mark, set the articulator upside down and place the interocclusal record on the maxillary cast. Place the www.indiandentalacademy.comthe record and check for mandibular cast onto stability.
  • 84. Place mounting stone onto the base of the cast and onto the mounting plate and hinge the lower frame closed until the incisal guide pin meets the incisal guide block. Make sure the condylar elements are seated flush against the posterior www.indiandentalacademy.com and superior walls of the condylar guides.
  • 85. Once the stone has reached its initial set remove the material used to stabilize www.indiandentalacademy.com the cast.
  • 86. Remove the interocclusal record. Loosen the incisal guide pin screw and make www.indiandentalacademy.com sure the upper and lower cast contact. Retighten the incisal guide pin screw.
  • 87. Many clinicians use a second mix to clean up the mounting and give it a clean and professional appearance. Make sure the incisal guide pin is positioned in www.indiandentalacademy.com the center of the incisal guide table.
  • 88. Setting the Condylar Guidance of the Articulator Using Lateral Interocclusal Records www.indiandentalacademy.com
  • 89. After removing the CR or MI registration material, release the locking tabs on www.indiandentalacademy.com the right and left fossa elements.
  • 90. Set both condylar guides to the 0° setting on the condylar inclination scale and set the progressive side shift guides to their most open position. Firmly tighten the left condylar guide locking screw and lightly secure the right condylar www.indiandentalacademy.com guide locking screw.

  • 92. www.indiandentalacademy.com Carefully seat the left lateral excursion interocclusion record on the upper cast.
  • 93. While lightly holding the articulator, gently seat the lower cast into the left lateral www.indiandentalacademy.com record and hold the cast in position.
  • 94. Note: The cast should seat evenly into the left lateral record. If the posterior teeth are raised out of the record the condylar inclination needs to be adjusted www.indiandentalacademy.com until the teeth are seated evenly in the record.
  • 95. To set the inclination of the right condylar guide, carefully loosen the clamp knob and rotate the guide until the teeth of the upper cast seat evenly in the www.indiandentalacademy.com lateral record.
  • 96. Tighten the clamp knob to lock the guide into position. www.indiandentalacademy.com DO NOT USE EXCESSIVE PRESSURE when tightening the clamp knob.
  • 97. Setting the Progressive Side Shift of the Articulator Using Lateral Interocclusal Records www.indiandentalacademy.com
  • 98. To set the right progressive side shift guide, loosen the right side shift holding screw and move the right side shift guide until it touches the side of the www.indiandentalacademy.com condylar element. Retighten the side shift screw.
  • 99. After the right condylar guidance has been recorded, the condylar guidance should be neutralized as previously described. Set the left condylar guidance www.indiandentalacademy.com using the right lateral excursion record.
  • 100. Many wish to set the condylar inclination of the articulator with a protrusive record. To utilize the protrusive record, first neutralize the condylar inclination and progressive side shift settings. Place the protrusive record on the inverted upper frame of the articulator and gently seat the lower cast into the protrusive record. Both condylar elements will have moved away from the posterior surfaces of their respective condylar guides. www.indiandentalacademy.com
  • 101. Using sight and touch, rotate the left condylar guide until the teeth on the left side of the upper cast seat evenly into the protrusive record, then tighten the #2432 Clamp Knob. Record the reading and repeat the procedure on the right side. Note: The latereal records are used to determine the progressive side shift settings. www.indiandentalacademy.com
  • 102. Technique for Fabrication of a Custom Incisal Guide Table www.indiandentalacademy.com
  • 103. An acrylic custom incisal guide table may be used to make a permanent disocclusive record of a specificwww.indiandentalacademy.com case or to prevent possible abrasion of the stone casts during manipulation of the articulator.
  • 104. The Dovetail Incisal Block is a convenient accessory which has been designed so that a custom acrylic guide may be easily removed and can later be easily www.indiandentalacademy.com replaced.
  • 105. www.indiandentalacademy.com Materials needed for fabrication of a custom incisal guide table.
  • 106. www.indiandentalacademy.com Raise the incisal guide pin 2-3mm and release the centric latch.
  • 107. Lubricate the rounded end of the incisal guide pin. Next, prepare the surface www.indiandentalacademy.com of the incisal guide table with 1-2 drops of self-curing acrylic monomer.
  • 108. www.indiandentalacademy.com Mix enough acrylic to cover the incisal guide table to approximately a 6 mm thickness.
  • 109. www.indiandentalacademy.com Once the acrylic has reached a doughy state, place it onto the incisal guide table.
  • 110. www.indiandentalacademy.com Close the articulator in centric position.
  • 111. Move the upper frame to produce a straight protrusive movement terminating in www.indiandentalacademy.com an end-to-end position.
  • 112. www.indiandentalacademy.com From centric, move the upper member to give a straight right lateral movement.
  • 113. www.indiandentalacademy.com Then, move the upper member to give a straight left lateral movement.
  • 114. Move through all intermediate excursions between the lateral and protrusive positions. Repeat the excursive movements until the acrylic has reached a firm www.indiandentalacademy.com stable consistency.
  • 115. www.indiandentalacademy.com Final custom incisal guide table.
