Tatum Unipost Implant Abutment Preparation Instructions using theTatum EZ-Prep Kit
Remove the Healing Cuff by turning the screw clockwise and then slide the cuff off.
Select the appropriate abutment (we now offer two lengths) and try it into the implant by using your HT.04, HT.10, or HT.11 and turn it to the left.
Try-In using your HT.11. Make sure the angled abutments rotate freely. Next, using high speed handpiece and a GW2 carbide bur, score the post at approximate vertical height required.
Screw the abutment into your hand held post holder instrument. Using a GW2 carbide bur to reduce the vertical height. Use a carbide disc to create a slot on the occlusal of the post if needed so a screw driver can be used as a driver.
Remember, the abutments have left handed threads and should rotate freely if they are of the angled design. If any resistance is felt, air abrade the threads with aluminum oxide to allow free rotation during cementation.
Rinse the internal of the implant with water. Acid etch the internal of the implant and abutment threads with 37% phosphoric acid. Wash and dry. Cement using Resiment or Panavia.
Carefully rotate the threaded post into place. Align the post to the predetermined position. Check for extrusion of the cement through the vent in the post.
Allow adequate time for cementing agent to completely set. Be sure to cement one abutment at a time. Mix a new batch of cement for each abutment as it sets up so quickly.
Using abutments one size smaller than the diameter of the implant creates a defined shoulder. Chamfer the shoulder to create a bevel on the implant.
Handpieces rotate clockwise, our abutments tighten counter-clockwise. This assures us of never loosening the post during the preparation process.
While most gross dimensions are done outside of the mouth, touching up these dimensions should be done with copius amounts of water using either SS White GWU16 or 18 carbide bur.
Using a diamond bur, prepare the abutment surface by lightly roughening the surface to aid in the cementation of your crown.
Using a diamond bur, perfect preparations and create proper gingival margins.
Place a anti-rotational groove on the abutment extending it onto the body of the implant
The final preparations should have proper gingival margins and the anti-rotational groove on the body of the implant.
Some clinicians use retraction cord while taking their final impressions
Take a final impression with crown and bridge impression material. Hydrocolloid impression material works extremely well with narrow diameter implant posts.
