Frequently Asked Questions

Answer: If your delivery unit has a vertical flat surface, in most cases, the universal docking is applicable. In case your delivery unit has a spare slot available for integration, then you can also make use of the adaptor docking, included in every start set. [This adaptor docking fits into the 15 mm slots of A-dec, Anthos, Kavo, Planmeca, … e.o.]. For units with different slot dimensions, special adaptors are available … These are separately available through your dealer. The most up-to-date overview on adaptors is to be found in the Integration Adaptors table in the download section …

Answer: Every Yirro-plus start set is to be connected directly to your compressor. The PREMIUM system is also to be connected with electricity. In all start sets, a separate installation instruction sheet is included, together with all connection supply. For connection to compressed air, a 6mm T-part (1/4”) is included. In the PREMIUM start set, a 24VDC medical power adaptor with interchangeable blades is included. This adaptor is suitable for 90-240VAC and can be connected to an electrical contact (EU, UK, US, AU) or to a terminal block by use of included wires / contra-connector. More detailled information is to be found in the separate installation instruction sheet [see ‘download section’]..

Answer: The Yirro-plus® system is connected independently from the unit to the 3-6 bar of the compressor. For the connection to compressed air, a 6 mm T-part (1/4”) is included. In all start sets, a separate installation instruction sheet is included, together with air connection supply. For COMFORT systems, an extra quick coupling [available in 2 types] is included, for direct access to an exterior air point of your unit. In case you don’t have an exterior air point available on your unit and you prefer to create one, we advise you to purchase a ‘female’ air connection set – separately available in 2 types [NW 2.7 – art. 0377 and Poly female – art. 0553].

Answer: NO. The Yirro-plus® system is developed to be connected independently from the unit to 90-240VDC by use of the included medical Power adaptor. Apart from this option it is possible to connect the Power/Air Box directly to 24VDC of the unit. More detailed information is available in the separate mounting & installation instruction sheet [see ’download section’]…

Answer: YES. Every service technician should be able to install this system independently from the unit, by use of the included connection supply. See also the separate installation & mounting instruction sheet [download section]. In case your technician has any questions in relation to the installation, let him contact us ...

Answer: Depending on the hour-rate and also of your situation, it will take about 30 to 40 minutes to install the system. When installing for the first time, your service technician might charge a one hour rate to cover unexpected difficulties. We recommend to plan the installation combined with the periodic maintenance, in order to decrease extra costs…

Answer: Apart from the mirror heads and the ø4 mm silicone hose there are no wearable components. The system has been designed such, that there are no moving parts that can break or malfunction. Apart from periodic cleaning routines after every patient treatment, no maintenance is needed …

Answer: YES. Demounting is easy, connections can be removed and the system can be transferred to another unit. Be aware that the universal mounting docking is mounted with strong adhesive tape and, when disconnected, the tape needs to be removed. Then clean the mounting surface and order for new tape, or, preferrably you could order a mobile docking holder [article 0518]; for easy clipping of the universal docking without visible screws. We recommend the transfer to be carried out by your service technician…

Answer: YES, but exclusively the Yirro-plus® COMFORT system applies here. In any COMFORT start set, two quick coupling are included for direct acces to exterior air connections on unit or on the wall. NOTE: there are 2 types of quick couplings included: [1] the male NW 2.7 quick coupling, suitable for users located in the area of northern Europe; and [2] the Polymale 4mm Q.D. coupling, suitable for users located in USA, Asia, Southern Europe.

In case you don’t have any exterior air connection and wish to create one, you can order a separately ‘female’ air connection set:
[ for the NW 2.7 type you should order article 0377 and for the Poly female type you should order article 0553].

[PREMIUM] If you prefer to use a PREMIUM system, we do not recommend to use your exterior air connection: both the air connection and the electricity wires remain outside from the unit – consequently the installation will appear much less sophisticated…. please consider to connect the air at the inside of the unit.

Answer: Yirro-plus® UHR mirrors can withstand a minimum of 200 times autoclaving. Apart from the cleaning and sterilisation process, the actual use plays a crucial role with respect to the wearance. Most users benefit from Yirro mirrors for about at least 6 to 8 months.

Use the Cleaningbox
In order to minimize wearance from the regular cleaning process, the special Yirro-plus® cleaning box was developed, for protected cleaning of 6 mirrors.

Use the autoclave caps (only when autoclaving)
In order to prevent so called ‘solid spots’ on the mirror surface, that can occur during sterilization, due to the inevitable residu in the autoclave water, the noSPOT autoclave cap was developed. When applying noSPOT caps during autoclaving, your UHR mirrors no longer need to be rubbed clean, only shortly rinsed with water, which shows the mirror to last longer…

Answer: Yirro-plus® mirror heads are provided with dielectric front surface reflective coatings, with extreme reflectivity (visually brighter when compared to a Rhodium front surface mirror). Yirro mirrors are further provided with a water- and grease-repellent multi-layered coating. The glass surface has been grinded and polished to be extremely flat; offering a highly reliable image, which can be made visible by directing a presentation laser pointer over the mirror surface …

Answer: The removal of composite fillings is a delicate thing, especially because in this situation the difference between the colour of the composite and the tooth material is hard to distinguish. Our users indicate that the use of Yirro-plus® when removing composite is more comfortable – Watch here a demo movie of composite removal in order to acces a root canal. Watch here a demo movie of the finishing of a crown preparation…

Answer: The flexible air hose has been deliberately chosen so that you can work as much comfortable as possible. The non-dominant side should not focus the attention of the dominant-side. The relative vulnerability of the hose is a direct consequence of this decision. It is however very easy for the dentist to replace this silicon hose. Should – after a period of time – the end of the air hose loosen or be damaged or leak, then this problem is solved easily by pulling the hose from the air outlet, cut off 1 cm and put it back in place. In case of a leak the air flow can be influenced and a replacement hose needs to be ordered. Replacement hoses are most affordable…

Answer: When determining the standard length of the air hose we calculated sufficient length to work comfortably. When the mirror is docked, pay attention that the hose does not touch the floor [hygiëne]. A length of 1.30 m has proven to be sufficient in most situations, with the docking on the delivery unit. For Cart-users, that tend to dock the mirror on the dominant side, a longer hose [1.80 m] is available. Should in your situation the hose not be long enough, contact your dealer, for request of the longer version of 1.80 m …

Answer: No such complaints have been made by patiënts during pre-tests and after. Nonetheless the experts have indicated a difference in patient-sensibility concerning the air flow in general. For this reason the regulation button was developed, in order to fine-tune the air flow individually. In some cases you might have to decide between your patients’ comfort and your own. Consider that the controllable air flow of the Yirro-mirror is less firm when compared to a triplex / multifunction syringe air flow…

Answer: This matter needs the proper attention. It is important for your assistant to know the cleaning and sterilization procedures, and also the preferred way of handing over the mirror before the treatment. Before and after every treatment the docking station and air coupling are to be wiped clean with alcohol or disinfectant. The air coupling is to be shortly lifted from the docking station in order to clean both docking and coupling. Instruct your assistant to either place a cleaned handle/mirror set in the docking before every treatment, or, if you prefer so, instruct the mirror to be placed on your dental tray. Please practice these cleaning and preparing routines a few times together with your assistant to make sure that the both of you become familiar with the ins and outs of the use…

Answer: The learning curve is different for each user. However, our users do not perceive the Yirro-plus system as difficult. The intuitive system offers a logic operation. Still, you and your assistant will need to get used to the presence of the siilcon air hose and the continuous flow of air on the mirror surface. Some TIPS: Pay attention that the air hose and the suction hoses do not conflict during work. Also learn to prevent, when taking out the mirror from the patients’ mouth, the air hose to touch the patiënts’ nose. If you work with coverdam, instruct your assistent to prevent a water basin, to avoid water to splash out by the air flow. Users indicate that they truly have had to ‘get used to the air hose’ but after a while they ‘no longer notice it’ and value ‘its comfort which simply outweighs these issues.’…

Answer: OFCOURSE. When starting a treatment, i.e. an examination, use the mirror without air hose. After a few moments, ‘dock’ on air and continue to work with air flow. TIP > Do you prefer to ‘start’ without the air? Instruct your assistant to place a clean Yirro-plus® dental mirror on the tray, not docked into the docking station. [COMFORT] When using COMFORT, you can ask your assistant to toggle the manual switch to switch OFF the air flow any time. You could instruct your assistant in advance. [PREMIUM] PREMIUM users have 3 options: a) disconnect the magnet coupling from the handle and dock it back into the docking, b) turn the regulator knob all the way to the right – the air flow will stop, or c) make use of the separately available foot pedal option [article 0268]. PREMIUM users that prefer to switch ON/OFF without having to re-focuss benefit from this foot-pedal option…

By use of the included cleaning box and autoclave caps, you can clean and sterilize your mirror heads safely. Make sure you separate handles from mirror heads and only use the autoclave caps when autoclaving/sterilizing. Preferably make use of the plastic program (124ºC, max 15 minutes) when sterilizing, to extend the lifetime of the durable plastics longest possible.

For more details, consult the Cleaning, Disinfection and Sterilization protocols (CDS) at our download page.

Docking station, air coupling and air regulation unit should be wiped clean before and after each use, according to hygienic Rules, by use of disinfectant.

Do not sterilize the magnet coupling and do not place it in a thermal disinfector … for it may loose the magnetic function.

Answer: If you make use of the foot pedal option, than shortly press the foot pedal during the cleaning process.. If you do not have this option, you simply shortly lift the coupling whilest cleaning it, quickly wipe clean the docking and place the coupling back into the docking. This operation can be done within a few seconds…

Answer: The Yirro-plus® system knows a statutory warranty of 1 year. (For more information about the warranty see section 8.1 and 8.2 of our General Terms.)..

Answer: Carefully check your delivery for any defects before use. If you report visual defects [broken or missing items] timely (within 7 days) by a written notice of the visible defects of your purchase, you are entitled to receive a compensation in the form of a new (partial) delivery. Used consumables like mirror heads do not apply to this rule. (See also our General Terms, Article 8.4)…
