What material is used in manufacturing?
The prosthetic components are made of stainless steel, intended for use in implantable products, in accordance with American Standard ASTM F138-13a.
What load (force in N.cm) does the component support?
We performed static fatigue tests on the implant-mounted component, where we selected the most critical condition, defined by the highest transmucosal height and lowest robustness component (Arcsys 3x6x5.5mm Angular Trunnion already angled at 20 °). This test was conducted according to ABNT NBR ISO 14801, which defines a standardized method for checking the mechanical strength of components against static fatigue (compression test) and dynamic fatigue. For this test, the component withstood an average value of 1725N. That is, a value much higher than the study by Ferrario et al (2004), where the average maximum force applied to a unitary (first molar) tooth of a healthy adult male is approximately 306N.
What is the behavior of the component (stainless steel) in relation to the interaction with the fabrics?
Although unprecedented in implant dentistry, the alloy used is implantable and has long been used in the medical field in implant devices, precisely because of its adequate biological response to tissues, as evidenced by the American standard ASTM F138-13a.
How does grade V stainless steel and titanium interact?
ABNT NBR 16044 defines the general requirements for dental implants. It specifies several issues, such as contact with materials of different chemical compositions. This standard cites another (ABNT ISO 21534), which defines the combination of ASTM F138 stainless steel (to be used as abutment manufacturing material) and Ti6Al4V (which is used in implant manufacturing) as suitable for biomedical application. , and can be used without major problems. Remember that most competing systems already work with chemical-mechanical divergence between the alloys used in implants (G4) and components (G5).O desgaste entre as faces existirá quando ambas estiverem em movimentos divergentes, o que não ocorre em razão da indexação rígida promovida pela confiabilidade da usinagem.

How is the drive performed? What force is required for optimal locking?
The drive must be performed by mechanical impact, through its own device. The Gavel is designed to provide this drive properly, providing safety for the user. The ideal locking is accomplished by the amount of beats that the professional submits to the prosthetic component. We recommend at least 3 (three) impacts to provide reliable locking. The practitioner can “complement” the activation with the most impacts; This does not bring any harm to the set.
What factors influence the drive (implant / component assembly clutch)?
The physical factors. It is therefore very important to observe them to ensure the passivity of component penetration into the implant chamber:
1) Fragments within the implant preventing the component from descending.
Solution: Irrigate the interior of the implant under pressure and aspirate with endodontic cannula (extra attention when it is installed associated with gap filling).
2) Excess fluid (blood / serum) inside the implant.
Solution: Irrigate the inside of the implant under pressure and aspirate with endodontic cannula.
3) Correct selection of transmucosal height so that it allows the component to descend to its final course in the implant without interfering with bone ridges or soft tissues.
Solution: Adjust the transmucosal height to avoid soft tissue pressure on the component and check for passivity as it descends. In case of contact with the bone crest, it is necessary to scar the region to guarantee the passivity of the settlement.
4) Hammer activation as recommended.
Solution: Align the Gavel along the implant axis as per instructions for use, properly trigger the trigger (holding in the specified area) and apply at least 3 full impacts.
5) Contact points on the prosthetic portion preventing descent of the prosthesis / component assembly when they are joined.
Solution: Check the contact points of the prosthesis and relieve if necessary. Check with dental floss.
6) Occlusal adjustment (absence of occlusion guides).
Solution: Adjust front and side guides. In mild occlusion (MIH), the prosthesis should not be marked by AccuFilm. In forced occlusion, the prosthesis should be lightly marked. This is due to the absence of periodontal ligament.
If reversibility is required, how to proceed? In the mouth there is no similar movement that makes it loose?
Its reversibility is possible and safe as long as the professional seizes the component with its respective extracting key. Just perform the twisting and pulling movements simultaneously (about 30N is enough to “nullify” the Morse effect). It is important to evaluate the presence of parafunctions (such as bruxism). In such cases, the occlusion must be adjusted according to the basic assumptions that govern it (freedom of excursion movements and selective touch during the occlusion guides). There is no possibility of loosening of the prosthetic component during masticatory function, since the compressive sense further favors the components' entrapment.
How to select the component? How to select the height of the transmucosal?
The transmucosal height comprises the distance from the top of the implant to the beginning of the prosthesis. Because it is a Morse system, the implant should be submerged in relation to the bone level (2-3mm). At this distance, the gum thickness is added. The total value obtained should allow the formation of a new biological space, and the rehabilitator should be aware of the need to hide the gingival terminus in approximately 1mm. These values should be measured with the transmucosal meter. The decision about height can also be postponed after conditioning by the healer, and only then make the choice of component.
Important:
It is essential to activate the selected component only after certifying the correct height has been selected. Otherwise, there may be loosening, understeering, exposure of the prosthetic termination, etc. In addition, if damage occurs during component replacement, the quality of the connection may be compromised.
Can the component rotate during prosthetic screw torque?
Yes. This can happen in two specific situations:
1) If the force applied to the prosthetic screw torque exceeds 30N (10N is recommended for stabilization).
2) If the prosthetic component is understeered. In this case, it will not be fully activated, and its grip may be reversed with force below 30N.
How do I remove temporary crowns from already activated components?
Removal of interim crowns or multifunction transfer crowns used as copings should be done only by traction movement (without rotation). In these situations, it will detach with a force of less than 212N, which is required to release the set (implant / component) after 3 impacts by the hammer.
