Definition and traceability

The NucleOSS Dental Implant System is an in-bone dental implant system with dental implants and related abutments, healing caps and surgical instruments. It is compatible with T6 and T6 Torq Superstructures, T6 and T6 Torq Dental Implants and the T6 and T6 Torq Surgical Set. Failure situations that may occur as a result of use with different systems may harm the patient. The product label gives the product code, specification and production date.

NucleOSS T6 and T6 Torq superstructures are prefabricated prosthetic components directly connected to endoosseous dental implants and are intended to be used as an aid in prosthetic rehabilitation. The system offers a wide range of superstructure options for different purposes with all bodies, including cemented, screwed, customised, removable prosthesis, cad-cam solutions and scan bodies, as well as auxiliary prosthetic parts and temporary parts.

CAD-CAM abutments are placed on dental implants to provide support for prosthetic reconstructions such as crowns or bridges. See the catalogue for the superstructures compatible with the platform diameter and length of the abutments.

Each superstructure package has a lot number on it, and there are three lot number labels inside each body pack. For retrospective traceability, it is strongly recommended that these labels are kept in the patient’s file together with the panoramic X-ray.

Intended use and target users

Intended use: the NucleOSS T6 and T6 Torq Dental Implant Systems are designed for use in dentistry. NucleOSS abutments and prosthetic parts are medical devices used to support mandibular and/or maxillary crown-bridge or superstructures in patients with total or partial prosthesis indications.

Points to consider

If the following warnings and precautions are not observed, complications may occur, such as the part entering the windpipe or swallowing the part.

During placement of the product, the dentist and auxiliary personnel must use appropriate personal protective equipment (PPE) to prevent the risk of interpersonal infection. The procedure should not be performed without gloves and masks.

For dental technicians:

  • When polishing the abutments, ensure that the part entering the implant is protected, or perform this process with the abutment attached to the implant analogue.
  • Place the abutment on the model by checking the correct orientation and make sure it is fully seated.
  • The abutment must be fixed with the abutment screw provided and tightened in accordance with the torque value given in the torque value table.
  • After this stage, the prosthesis suitable for the treatment should be created and removed from the model with the help of the correct hex key.

For dentists:

  • The clinician should take the abutments from the laboratory and remove the temporary restorations, closure screws or healing caps from the patient’s mouth.
  • After cleaning, disinfecting and sterilising the prosthetic parts from the laboratory, the clinician should apply them to the patient’s mouth by tightening them with a tightening piece according to the specified torques.

Before surgery: a clinical and radiological examination of the patient should be performed preoperatively to determine whether the patient is suitable for treatment and to determine his/her psychological and physical condition.

Special attention should be paid to patients with localised or systemic factors that may interfere with the bone or soft tissue healing process or the osseointegration process (e.g. smoking, poor oral hygiene, uncontrolled diabetes, facial radiotherapy, infections in the lateral tooth or bone, bisphosphonate therapy).

The device has not been evaluated in paediatric/adolescent patients and is not recommended for use in children.

Surgery: all components, devices and instruments used during the procedure must be kept in good condition, and care must be taken to ensure that the instrumentation does not damage implants, superstructures or other components. Following implant placement, the surgeon’s assessment of bone quality and primary stability determines when the implants can be loaded. The choice of superstructure and the time of application should be evaluated.

After surgery: to ensure a long-term treatment outcome, regular comprehensive patient follow-up after implant treatment is recommended, together with the necessary information on proper oral hygiene.

Residual risks and side effects

The clinical outcome of dental treatment can be influenced by many variables. Possible residual risks and side effects may occur during or after the operation:

  • Pain, swelling, phonetic difficulties, gingivitis.
  • Dental implants, permanent paresthesia, dysesthesia, marginal bone loss, localised or systemic infections, oroantral or oronasal fistula, disruption of adjacent teeth, irreversible damage to adjacent teeth, implant fractures in the jaw, bone or prosthesis, nerve damage, exfoliation, chronic pain associated with hyperplasia, implant failure, fractures in the neck area where the implant and abutment meet, screw loosening or fracture, abutment fracture, abutment compression into the implant.

Procedure

Final prosthetic treatment with an implant can only be performed after the soft tissue has healed and is free of inflammation. The clinician selects the abutment based on the patient’s individual situation. Abutment choice depends on implant diameter and mucosal thickness. Great care should be taken in choosing the abutment according to the diameter and angularity of the implant, as well as the gingival height.

Digital solutions Ti-base abutments

Use by the dentist (steps 1 to 4), then the technician (steps 5 to 10), then the dentist again (steps 11 to 13).

  1. Dentist: before placing the abutment on the implant, remove the healing cap or temporary abutment and clean the inside of the implant.
  2. Dentist: in digital solutions, use scanning parts to take an intraoral scan of the patient.
  3. Dentist: connect the scan part to the implant with the M.1.6 connecting screw using a Hex wrench. The flat surface on the part shows the Hex direction of the implant to which it is connected.
Step 3: connecting the scan part to the implant with the connecting screw.

Preparation of bridge prosthesis, step 2: the multi-unit tibase abutment (T6 32813) and occlusal screw (T6 16009).
  1. Multi-unit tibase abutments are placed into the created dental prosthesis and checked. After the necessary corrections are made, cement adhesive is applied into the dental prosthesis. Multi unit tibase abutments are placed and the cement is waited to set. At this stage, be careful not to let the cement get into the tibase abutment.
Preparation of bridge prosthesis, step 3: cement adhesive applied and tibase abutments placed into the bridge.
  1. After the cement adhesive sets, the created bridge dental prosthesis is placed on the multi-unit analogues in the 3D dental model.
Preparation of bridge prosthesis, step 4: the bridge placed on the analogues in the 3D model.

Checking the bridge dental prosthesis

  1. After the bridge dental prosthesis is placed on the multi unit analogues, occlusal screws are also placed.
Checking the bridge prosthesis, step 1: occlusal screws are placed on the bridge.
  1. Its compatibility with the teeth on the right and left is checked. After the necessary corrections are made, the bridge dental prosthesis is sent to the clinic to be installed in the patient’s mouth.
Checking the bridge prosthesis, step 2: fit against the teeth on the right and left is checked.

Placing the bridge dental prosthesis in the patient’s mouth

  1. The created bridge dental prosthesis is placed on the multi-unit abutments in the patient’s mouth. Occlusal screws are tightened using a manual hex driver until they hold on to the multi-unit abutments.
Placing the bridge in the patient's mouth, step 1: bridge placed and occlusal screws tightened by hand.
  1. The occlusal screw is tightened with a torque ratchet until it reaches a maximum torque value of 20 Ncm.
Placing the bridge in the patient's mouth, step 2: occlusal screw torqued to a maximum of 20 Ncm.
  1. The screw hole in the tooth occlusal is closed with Teflon and filling material is applied and hardened. When it is desired to disassemble the total prosthesis, this material is removed and the screw is removed.

Once the NucleOSS abutment is secured to the implant with the specified torque, it should not be removed.

Caution: applying torque higher than the recommended torque may result in failure of the abutment and/or implant. Less than the recommended torque may result in loosening of the abutment, which may result in abutment and/or implant failure.

This procedure should be considered a minimum guideline; details are given in the NucleOSS Surgical Manual (https://www.nucleoss.com/kaynaklar/download/).
