INTRAORAL SCANNER - Instructions for use

The intraoral scanner is a portable medical device capable of three-dimensional scanning of dental arches generating a digital imprint better than a conventional silicon/alginate/hydrocolloid imprint in terms of marks, precision and accuracy. Thanks to a sophisticated optical system it allows obtaining a digital imprint of:

- stumps (after preparation), single crowns, 3, 4 or 5-element bridges;

- complete dental arches (for orthodontics);

- abutment from scanning for implant repositioning.

Conventions used in this manual

Throughout this manual the term scanner will be used both to identify the handpiece and the 3D scanning system as a whole (the product), depending on the context. The following abbreviations are also used:

PC: Personal Computer 3D-Progress: technical product name, also referred to as scanner MHT: Medical High Technologies S.p.A. a socio unico, Verona (VR), Italy – also referred to as the manufacturer

Introduction

USB: Universal Serial Bus (data transfer system from devices to PC) LAN: Local Area Network (PC) W-LAN: Wireless LAN

General warnings

- The intraoral scanner (system) and the relative software and drivers are developed and manufactured by MHT, Verona (IT), hereinafter referred to as the manufacturer.

- These instructions describe how to correctly and safely use the scanner. In order to use the scanner system, you need image acquisition and storage software. For software installation and use refer to the relative manual code 97050264. Please carefully read both manuals before starting to use the scanner.

- The purpose of scanning is to acquire and display digital imprints, similar to what was traditionally done with resin moulds. This operation does not in any way affect the diagnostic examination, which is assumed to have been carried out at the time the imprint is acquired, nor the subsequent treatment, such as prosthesis application, implants or orthodontic treatments which are decided and carried out by the orthodontist.

- No part of this publication may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, photocopying, recording or otherwise, without the prior permission of the manufacturer.

- MHT pursues a policy of continual improvement of its products, therefore, some specic instructions and images contained in this manual may differ from the product purchased. MHT reserves the right to make

any modication to this manual without prior notice.

- The information, technical specications and illustrations contained in this publication are not binding. The manufacturer reserves the right to make technical modications and improvements without modifying the-

se instructions.

- Warning: in observance of the privacy laws in force in numerous countries, suitably protect sensitive personal data and, moreover, before sending patient images or personal data via computer, informed consent must be obtained from the patients.

INTRAORAL SCANNER - Instructions for use

Warnings for use

- Electronic equipment may cause and suffer from interferences when used in proximity of other electromagnetic equipment, in particular mobile phones, personal computers equipped with W-LAN cards, microwave ovens. Avoid keeping the scanner and the PC intended for acquisition and storage of the scans in proximity of RF sources, such as W-LAN cards, other radio devices, home RF devices, microwave ovens; the recommended distance is at least 1 metre and at least 2 metres in the case of microwave ovens.

- It is recommended to install an up-to-date rewall and antivirus protection program on the PC and to use it exclusively for work purposes.

- In the event of malfunctioning of the PC during an intraoral scan (software or operating system crash or PC failure) the scan in progress will be interrupted and it might be impossible to retrieve it. Previous scans saved to the PC (database) will normally not be lost; nevertheless, if the damage to the PC is serious (mainly to the hard disk or the operating system in general) the scans saved might not be usable or viewable. It is advisable to regularly make backups of the scans you have made, keeping the backup of the database (or databases) on the PC up to date on secure and controlled mediums.

- For installation of the other system components (PC network, personal data storage and management software), it is advisable to contact specialised technicians.

- The USB connection the scanner uses is not a normal electrical connection, but requires specic USB 2.0 cables (recognisable by the marking USB 2.0 Hi-speed, see “Product identication”). The cable is type “A-

B” (provided).

Introduction

The 3D image acquisition system uses a fragile optical system sensitive to impact. Be very careful not to drop it during use or when housing it in its seat. Should the optical window break, the device becomes unusable.

The scanner can pick up relatively weak signals, therefore particularly intense electromagnetic disturbances may interfere with image acquisition. The scanner transmits the acquired images to the PC in real-time where they are processed and stored. Therefore, in the event of interferences, just restart the scanner to continue the acquisition without any risk to the patient or the operator, the only disadvantage being that the procedure will be completed with a few seconds’ delay.

- The power supply and the PC generate heat, therefore, they should be used in a relatively ventilated

position (not closed in a cabinet) ; pay particular attention to the support surface; use only hard and clean surfaces and avoid carpeting, mats, etc.

- Always use the key switch to turn off the scanner when it is not used and remove the key from the power

supply to prevent unauthorised persons from using the instrument.

- Do not turn off the scanner during scanning; if you need to interrupt work, use the buttons on the scanner

handpiece.

- Never disconnect the scanner cable from the power supply without rst turning it off using the key, as you

risk seriously damaging it.

- The warranty does not cover faults caused by tampering, improper use and evident negligence in use of

the product.

Safety and hygene

Warning! The scanner is a medical device for digital acquisition of dental imprints. It may onlybeusedbyqualiedodontologicalstaff.Donotusethesystemforpurposesotherthanacquisition of endoral scans, and do not use it if you do not have the necessary knowledge in the odon-

tologicaleld.

Warning!Inaccordancewiththe60825-1standards,thedeviceisaproductcontaininganin- frared laser. Infrared radiation is invisible to the human eye and for this reason might be dangerous. Scrupulously follow the safety instructions below.

Introduction

- The instrument does not directly emit a laser beam (even though it contains a laser source). The outer casing of the instrument blocks light radiation emission, except through the acquisition window. This window is positioned at the front of the instrument circled red in the image below. Radiation is emitted only during scanning, i.e. from the moment you press the Start/Stop button to the moment when you press it again; this will be indicated by a yellow LED on the device keypad coming on.

- Always use safety goggles. Safety goggles must be worn by the operator, the assistant and the patient (and any other person in the room where the instrument is used) throughout acquisition. The goggles must have

an optical density of at least 1, specically for use with infrared sources (808 nm)

- Performing procedures different from those specied in this manual may cause exposure to dangerous

levels of radiation.

- For any reason do not try to open the scanner casing.

In order to prevent transmission of infectious diseases from patient to patient, it is essen-

tialtoalwaysusethedisposableprotectionsprovided.Thedisposableprotectionsareclassiedas

Class IIa medical device and may not be replaced with others in a lower class. For spare disposable protections, contact the dealer that supplied the scanner. It is also essential to disinfect the product as described in the section “Cleaning and disinfection”.

- Cover all the components that will come into contact with the hands of the odontological staff with disposable protections, as they might be contaminated by indirect contact with the patient’s mouth. In particular, be careful how you handle the mouse, keypad, PC and scanner handpiece.

Cleaning and

disinfection

• Applying the disposable hygienic protections

• Warnings for disposal

Page 22

INTRAORAL SCANNER - Instructions for use

Cleaning is the rst step necessary in any disinfection process.

The physical action of rubbing a surface with detergents and surface-active agents and rinsing with water re-

moves a large number of microorganisms. If a surface is not cleaned rst, the disinfection process cannot be

successful. When a surface cannot be adequately cleaned, it should be protected with barriers.

WARNING! The container of the electronic interface is not protected against penetration of liquids.

The outer parts of the device must be cleaned and disinfected using a product for hospital use with indications

for HIV, HBV (low-level disinfectant) or tubercolocide (medium-level disinfectant) specically for small surfaces.

For use, follow the manufacturer’s instructions. The large variety of drugs and chemical products used in dentist’s surgeries may damage the painted surfaces and the plastic parts. The tests and research conducted have demonstrated that the surfaces cannot be fully protected against attack of all the products found on the market. The aggressive effects of chemical products also depend on the time they stay on the surfaces. It is therefore important not to leave the product on the surfaces of the device for longer than the time indicated by the manufacturer. Given the aggressiveness of the active ingredients used in disinfectants, it is recommended to use products that at maximum contain:

- 96% ethanol. Concentration: maximum 30 g for every 100 g of disinfectant;

- Propanol. Concentration: maximum 20 g for every 100 g of disinfectant;

- Combination of ethanol and propanol. Concentration: the combination of the two must be at maximum 40 g for every 100 g of disinfectant.

The manufacturer has performed compatibility tests between the main disinfectants available on the market and the plastic materials used in the manufacture of its products.

The following products proved to be the least aggressive:

- Incidin Spezial ( Henkel Ecolab );

- Omnizid (Omnident);

- Plastisept ( ALPRO )(non- tubercolocide as not alcohol-based);

- RelyOn Virkosept (DuPont);

- Green & Clean SK ( Metasys )(non-tubercolocide as not alcohol-based).

These tests demonstrated that the above mentioned products can be used, provided that the following warnings are observed:

WARNING!

- Do not use products containing isopropyl alcohol (2-propanol, isopropanol).

Cleaning and disinfection

- Do not use products containing sodium hypochlorite (bleach).

- Do not use products containing phenols.

- Do not spray the product directly on the device surfaces.

- Do not mix the above mentioned products with each other or with different liquids.

- Whatever product you use, follow the instructions given by the manufacturer.

Cleaning and disinfection:

For cleaning and disinfection use disposable, soft, non-abrasive paper (do not use recycled paper) or sterile gauze. Sponge cloths or any other re-usable materials are not recommended. Never spray directly onto the surfaces, but moisten a soft cloth and use it to clean the surfaces of the device.

22 EN

Page 23

WARNING!

INTRAORAL SCANNER - Instructions for use

- To clean devices connected to the mains power supply, turn off the devices and disconnect the power supply before carrying out the cleaning and disinfection operations of the outer parts.

- Everything used for cleaning and disinfection must be thrown away after use. Dispose of the materials in accordance with the regulations in force.
