Abutment screw retrieval kit manual

Metric screws that connect the implant abutments to the implant body can break due to overloading, and the broken lower portion may remain inside the implant body. NucleOSS offers the abutment screw retrieval kit (CRH 113) to provide solutions for such situations for physicians and technicians.

The hex region and throat part of an abutment may also break as a result of overload, leaving the broken lower part inside the implant body. The kit includes a broken abutment removal part for that situation.

• The kit is suitable for NucleOSS T6 Standard and T6 TorQ implants.
• The broken abutment removal part is likewise suitable for T6 Standard and T6 TorQ implants.
• The kit box is made of stainless steel and the tool holders are silicone.

For indications, contraindications and MRI information, see the implant instructions for use.

The kit consists of 4 parts.

Clean the inside of the implant body where the metric screw has broken with water, vacuum and air. Place the centering device carefully over the implant.

Caution. A screw removal drilling machine should not be used without a centering device.

1. Remove the upper part of the broken abutment from the implant before using the broken abutment removal part.
2. Clean any debris in or around the abutment by vacuuming.
3. Press the broken abutment removal part manually against the fracture fragment remaining in the implant and rotate it counterclockwise.
4. When a torque value that cannot be achieved by hand is reached, continue with a torque ratchet.
5. After approximately one more turn of torque with the ratchet, pull the fractured abutment removal piece vertically upwards. The fractured portion of the abutment is removed from the implant along with the abutment removal piece.
6. If the piece does not come out of the implant, repeat the procedure, increasing the tightening force with the torque ratchet.

Maintenance and cleaning of surgical hand tools:

• Careful use of all tools is extremely important.
• Even the slightest damage to the ends of the drill adversely affects cutting performance and therefore the clinical outcome.
• Even if a drill is used correctly and is clean, its cutting performance is reduced after a certain number of uses. The maximum milling for NucleOSS drills is 15 times.
• Avoid contact between the ends of the drills and any hard surface other than the bone.
• Use each surgical set piece according to its purpose and method of use. Other uses may damage the part.
• Never allow surgical residues (blood, bone and other tissue residues) to dry on a tool. Clean immediately after surgery.
• Clean thoroughly with only soft brushes so as not to cause wear and scratches on the tools. If necessary, remove the removable parts of the tools and clean the gaps.
• Never disinfect, clean (also ultrasound) or sterilise instruments made of different materials together.
• Use only cleaning agents and disinfectants for the material and follow the manufacturer’s instructions for use.
• Rinse disinfectants and cleaning agents thoroughly with water.
• Never leave or store tools moist or wet.

Caution. The manufacturer accepts no responsibility for devices initially delivered non-sterile, regardless of who performs the sterilisation or by what method. Because conditions and environments vary, the ultimate responsibility for implementing and verifying procedures to achieve sterility rests with the user. Non-sterile surgical instruments should not be used under any circumstances.

1. Place properly cleaned and dried instruments into the designated slots inside the surgical set box.
2. The surgical set is made of highly impact-resistant plastic materials suitable for autoclave sterilisation. In clinical autoclaves the parts can be sterilised as a single piece without being removed from the box.
3. Place the surgical set container in the autoclave bag.
4. After the cycle is complete, remove the surgical sets from the steriliser and place the tray on a padded surface to prevent condensation during cooling.

Caution. Do not stack boxes while performing the sterilisation process, as this may affect sterilisation effectiveness.

The sterilisation processes are validated in accordance with the current international standard, ISO 17665:2024. The manufacturer’s instructions for use for all detergents, cleaning solutions and equipment and accessories used in cleaning and disinfecting the devices must be strictly followed.

After sterilisation, store the devices in a dry, dark place, such as a closed cupboard or drawer.
