Titanium and titanium alloy dental implant attachments
1 Scope
This standard specifies the performance requirements and corresponding test methods for the dental implant attachments of titanium and titanium alloys, as well as the packaging.
The dental implants in this standard refer to various ancillary components used in conjunction with dental implants to support the upper structure (prosthesis) of the implanted denture, including abutments and central screws. The dental implant attachments in this standard also include the cover screw, healing cap, and healing abutment which are used on the implant before assembling the upper structure. This standard does not cover the devices used for the upper structure which is made in the dental laboratory (e.g. transfer body, retention screw, connection ring, and upper structure, etc.).

Note. The abutment can be connected to the implant via a central screw, OR otherwise connected to the implant through embedding or other
methods.
3.5
Central screw
A screw that penetrates the center of the abutment AND fastens the
abutment onto the implant.
3.6
Cover screw, healing screw, closure screw
After the implant is implanted in the jaw, the cap structure above the implant is screwed in to avoid tissue growth. During secondary operation, the cover screw is taken out, AND the abutment is installed in place.
3.7
Healing cap/hygiene screw, hygiene cover screw, hygiene cap
Attachments which are temporarily installed onto the abutment end.
3.8
Healing abutment
A transitional abutment. In the soft tissue healing period after surgery, the healing abutment is attached to the implant, which helps the soft tissue to be shaped in accordance with the shape of the healing abutment AND then replaced by the abutment.
4 Material
It shall comply with GB/T 13810-2007 Wrought titanium and titanium alloy for surgical implants.
5 Requirements
5.1 Appearance
the tweezers to take all the implant attachments out from the beaker; USE the qualitative filter paper to filter the liquid in the beaker; AND there shall be no visible attachment on the filter paper.
6.7 Fatigue limits
MAKE test in accordance with YY/T 0521-2009, AND the test results shall comply with the provisions of clause 5.7.
6.8 Chemical composition
MAKE test in accordance with GB/T 4698-1996, AND the chemical
composition shall comply with the provisions of clause 5.8.
6.9 Sterile
MAKE test in accordance with the Appendix XI H “Sterile test method” of the Pharmacopoeia of the People’s Republic of China (Volume II), AND the test results shall comply with the provisions of clause 5.9.
6.10 Pyrogen
MAKE test in accordance with the Appendix XI H “Pyrogen test method” of the Pharmacopoeia of the People’s Republic of China (Volume II), AND the test results shall comply with the provisions of clause 5.10.
7 Packaging, marking and instruction manual
7.1 Product marking
If the size and surface conditions of the dental implant attachment permit, under the preconditions of not affecting the use performance of the dental implant attachment, it shall make clear manufacturer marking, product batch (serial) number, and specification marking on an appropriate region at each dental implant attachment surface. However, if the size and surface conditions do not permit, it shall use the label or other methods to provide the information required, in order to ensure the traceability.
7.2 Labeling and packaging mark
The labeling and packaging mark of dental implant attachment shall include at least the following.
a) Product name, model, specification;
