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.
The system offers dentists a wide range of superstructure options for different purposes, including cemented, screwed, customised and removable prostheses, CAD-CAM solutions and scan bodies, as well as auxiliary prosthetic parts and temporary parts.
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.

Warnings and precautions
Observance of precautions and warnings ensures safe handling and application.
- Use of the NucleOSS brand and sale of NucleOSS Dental Abutment System products are restricted to NucleOSS and its business partners.
- All models in the NucleOSS Dental Abutment system (T6, T6 TORQ) should be applied according to NucleOSS Surgical and Prosthetic protocols.
- It should be kept out of the reach of children.
- The abutment suitable for the patient’s oral structure should be used with the appropriate dental implant.
- The patient should be informed before and after the surgical operation.
- Abutments with damaged packaging should not be used.
- Make sure that the patient’s health condition is suitable for the operation.
- Abutments are sold as non-sterile. Before use, they must be sterilised by the user as specified in the instructions for use.
- Previously used abutments cannot be reused.
Warnings 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.
- If the superstructures are tightened more or less than the specified torque values, it may cause the abutments and/or implants to fail.
- The appropriate torque values for the use of superstructures are in the torque table (see the tightening torques section).
Points to consider and precautions
If the following warnings and precautions are not observed, complications may occur, such as the part entering the windpipe or swallowing the part.
During the 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, it should be ensured that the part entering the implant is protected, or this process should be performed with the abutment attached to the implant analogue.
- The abutment should be placed on the model by checking the correct orientation and making sure that 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 the prosthesis should be removed from the model with the help of the correct hex key.
Before surgery: 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.
NucleOSS superstructures are medical devices that do not require installation. It is strongly recommended that specialists who will use NucleOSS superstructures for the first time receive training from NucleOSS. Users who need more information can contact NucleOSS dealers or representatives, or NucleOSS by e-mail at info@nucleoss.com.
After surgery: to ensure a long-term treatment outcome, it is recommended to ensure regular comprehensive patient follow-up after implant treatment and to provide 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.
Tightening torques
The torque table for superstructures covers several component types, not only cast abutments. The cast abutment screws fall under “All Universal Cast Screws” (Max. 30 Ncm).

Procedure for cast abutments
Final prosthetic treatment with an implant can only be performed after the soft tissue has healed and is free of inflammation.
The abutment is selected by the clinician 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.
Use by the technician (steps 1 to 6):
- Step 1. The universal Ti-base cast abutment is placed on the standard analogue in the plaster model.
- Step 2. The casting cap is placed on the universal Ti-base casting support and the long connection screw is carefully placed on the standard analog with the help of a manual hex wrench.
- Step 3. In CoCr cast abutments, the casting cap and Ti-base abutment are combined. The CoCr cast abutment is placed on the standard analogue in the plaster model with the help of the laboratory screw (16007).
- Step 4. After the casting cap is placed on the support, cutting is done on the casting cap based on the teeth on the side. A wax model is made on the cut casting kebab.
- Step 5. The long connection screw (for universal Ti-base casting abutments) / laboratory screw (for CoCr casting abutments) is removed, and the created wax model is sent to the casting process.
- Step 6. After the created wax model has gone through processes such as casting, coating and polishing, it can be attached to the plaster model or directly to the patient.
Attention: for universal Ti-base abutments, only the wax model and casting kebab are sent to the casting process; the universal Ti-base abutment does not enter the casting process. For CoCr cast abutments, the wax model created on the casting kebab and the support enter the casting process together. Since the base consists of chrome and cobalt alloy, it is not damaged at high temperatures.
Use by the dentist (steps 7 to 9):
- Step 7. The universal Ti-base cast abutment / CoCr cast abutment is carefully placed on the implant in the patient’s mouth. The dental prosthesis is placed on the Ti-base abutment. Then the long abutment screw (for universal cast abutment) / connection screw (for CoCr cast abutment) is tightened by hand with the help of a manual hex wrench, enough to hold the implant.
- Step 8. The long abutment screw (for universal cast abutment) / connection screw (for CoCr cast abutment) is torqued to a maximum of 30 Ncm with the help of the NucleOSS torque rack.
- Step 9. Finally, the procedure is completed by filling the screw hole on the prosthesis.
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 in the NucleOSS Surgical Manual (https://www.nucleoss.com/kaynaklar/download/).
Expected clinical benefit and safety summary
Patients can expect to have one or more missing teeth replaced and/or crowns restored to restore chewing function as a benefit of treatment.
