Instructions for removing abutment screw from Multi-Unit abutment
[Exclusively for AnyRidge® system]

screw-and-abutment-step1d

1. Completely unscrew abutment screw by rotating it counterclock wise approximately 4 rotations are required). Use with a Hand Driver (ref code: MUHD1220).

screw-and-abutment-step2d

2. Pull the Hand Driver up straight until it is visible through abutment screw hole. Shaking left and right may be required if the screw becomes stuck inside of the abutment hole.

screw-and-abutment-step3d

3. Slightly rotate the screw to the main access hole. Otherwise the screw could fall back into the screw hole due to disturbance of abutment structure.

screw-and-abutment-step4d

4. Remove abutment with the Removal Driver (ref code: MUARD20) by rotating it clockwise.

Driver Tightening Torque Guide

driver-touque-col1
driver-touque-col2
  • Excessive torque more than 30Ncm may cause fracturing of the driver.
  • Straight type Multi-Unit Abutment needs to use the Multi-Unit Driver that is provided in the starting package. (ref code: MUD10)
  • Strongly recommended to pick up the abutment screw by pressing the Hand Driver to remove the abutment screw from the Multi-Unit Abutment.

Surgical Protocol:
Conventional Surgery

1. Initial Drilling

For placement of center pin after initial drilling in the centric of the arch. The drilling hole should be in lingual area of the arch to ensure the best result.

1-initial-drilling

2. Guide Bending and Position

Bend according to the patient’s arch.

2-guide-bending-and-position

3. Drilling

Drill according to the surgical plan.

5. Try-in Abutment

Using the laser marking on the Try-in abutment, select the appropriate cuff height and angulation of Multi-Unit abutments.

5-try-in-abutment

6. Abutment Selection

Select the appropriate kit after checking the angulation and cuff height that were measured with the Try-in abutment. Connect the abutment onto the fixture and check the angulation and the cuff height.

7. Tightening the Abutment

Straight Abutment tightening Torque: 35Ncm After removing Carrier, connect Abutment to the Fixture using Right Angle Driver or MUA Driver.

7-tightening-abutment

Abutment Screw tightening Torque: 25Ncm After connecting Abutment Screw, remove Carrier from Abutment. For 17˚ abutment, you need to tighten it by tilting Driver about 5˚. Connect Abutment and check the path using Carrier.
