INTRAORAL SCANNER - Instructions for use

Introduction

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 sy-

stem 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

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 sy-

stem, you need image acquisition and storage software. For software installation and use refer to the rela-

tive 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.

Introduction

Warnings for use

- Electronic equipment may cause and suffer from interferences when used in proximity of other electroma-

gnetic equipment, in particular mobile phones, personal computers equipped with W-LAN cards, micro-

wave 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 sa-

ved 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).

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 scan-

ner 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.

Introduction

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acqui-

sition 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.

- The instrument does not directly emit a laser beam (even though it contains a laser source). The outer ca-

sing 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 disposa-

ble 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.
