Sažetak
This case report presents a non-invasive method of removing two broken implant screws using ultrasonic scaler. A 49 years old male patient presented with a 3 unit screw retained bridge (14- 16) which had fallen out, due to screw fracture on both implants. Examination and intraoral x-rays showed two dental implants, in good position, with slight crestal bone resorption. The screws were fractured below the level of the hexagonal lock. Small incision was made in order to access the screws. A small pit was formed with a carbide bur. The ultrasonic scaler tip (Great Star G3, GGEE Co., Ltd, China) was placed in the pit and slow anti clockwise movement was applied, which was gradually increased. The implant screw at position 14 was retrieved after 2 minutes of anti-clockwise movement, and the implant screw at position 16 was retrieved after 4 minutes of movement. After removing the screws, a control x-ray was taken in order to confirm the removal of the screws. The internal surface of the implants was uncontaminated and the same screw retained bridge was placed with two new screws which were tightened up to 25 N/cm. No clinical problems were observed at 6 months follow- up.The use of Ultra sonic scaler can be a successful non-invasive method for retrieving broken implant screws. It is of great importance to avoid damage to the internal hex of the implants which can lead to prosthodontically unrestorable implants.
