  3. 3. An impression is taken and a cast is made, a hole is drilled in thecast at the #19 site planned for implant placement with a 3/32” drill.
  4. 4. A 3 mm guide post is placed in the hole.
  5. 5. A 3 mm X 8 mm guide sleeve is placed over the guide post. The angle of theguide post is not critical as this is for a DIAGNOSTIC guide which will beevaluated and corrected using information from a cone beam X-Ray.
  6. 6. Under cuts are blocked out and petroleum gel is used to lubricate the cast. Triad®Gel is added to the brackets of the guide sleeve and the adjacent teeth to form thebody of the DIAGNOSTIC guide. The guide is placed in the patient for the ConeBeam X-ray.

The set screw is tightened against one of the four flatAn orientation dot is designed to mark sides of the guide post with the orientation dot in view.the buccal surface. The purpose of the set screw is to prevent rotation while the guide post is being bent.

After the 1st bend is complete, the set screw is released and the guide post is rotated90° counter clockwise until the next flat surface (representing the buccal surface of theguide post) is aligned with the set screw.The set screw is retightened.When rotated the stylus raises up off the plate and points to the 0 degrees.A stylus support bar is moved down to support the stylus to maintain the angle of thefirst bend while the second bend is being made.

  26. 26. Guide Right™ GUIDE POST BENDING TOOL SINGLE BEND reviewStep 1 Place bending tool plate on a secure flat surface with the degree increments at the top & the stainless steel bar with the v-cut at the bottom.Step 2 Locate 3/32” hole in the center of the v-cut and place the bottom half of the guide post into the hole. Tighten the set screw.Step 3 Locate the hole in the bottom of the stylus that you will use that will fit over the top half of the guide post (3.0 mm, 4.0 mm or 5.0 mm).Step 4 Fit the stylus over the guide post securely with the point directed at zero degrees and the bottom of the stylus in contact with the V block.Step 5 Using the stylus as a lever, bend the guide post to the degree of angle of correction. You may need to ease the point of the stylus beyond the point of the desired degree.Step 6 Loosen screw and remove guide post and the stylus to find the guide post bent to the desired angle.
  27. 27. Guide Right™ GUIDE POST BENDING TOOL COMPOUND BEND overviewStep 1 Position a straight or offset guide post in the bending plate, tightening the set screw against one of the flat surfaces on the lower half of the guide post.Step 2 The 1st bend can be made to the right or left direction.Step 3 The set screw is loosened and the guide post is rotated 90 ° next flat surface.Step 4 The 2nd bend in the second plane is made after rotating the guide post up away from the surface of the bending plate to register the stylus point back at 0 degrees.Step 5 Slide the stylus support bar down under the stylus until it supports the stylus. Tighten the side screws before making the second bend.Step 6 The second bend can be made in either direction according to the x-ray.Step 7 Remove the stylus and place the guide post back in the cast with the appropriate side indicated by a mark facing the buccal or lingual surface. Be sure the post is in the correct position. If the post needs to be corrected by a linear movement an offset guide post can be used. Off sets available in the 3 mm guide post: 0.5,1,1.5, 2.0 ,or 3.0 mm.
