Introduction

DT1 software allows to program BLT and to view data via graphic user interface or printer. In Install section the steps essential to DT1 install onto your computer are described, both in Windows and Macintosh environments. In the following section, you'll find more details regard DT1 characteristics and utilization.

System requirements and install

DT1 is supported on the following platforms:

• Windows XP - 32bit
• Windows Vista - 32bit
• Windows 7 - 32bit
• MacOS 10.6 - Snow Leopard - Intel architecture

In following sections, how to install this software in different cases is described.

Windows

Insert install CD, open Windows Explorer and execute the DT1/WIN32/setup.exe installer, following the instructions. In the first window, select the language you prefer during the install. Then, repeatedly press Continue (or similar button) until installation completion.

At install's end, a new icon will appear on desktop, that will allow you to open directly the program.

MacOS

Insert install CD, wait until operating system views the disk and copy DT1/MAC/DT1.app among applications.

Setting up the Bluetooth configuration

Before connecting the DT1 software to the remote device, the latter has to be made visible to the Operating System. According to your Operating System version, there are different (yet similar) steps to make the pairing between the device and the OS, as discussed in the following sections.

NOTE: whichever Operating System you have, the Passkey value for the pairing is always: 0000 (four zeroes).

ATTENTION: be sure that your pc has a working Bluetooth interface installed. Otherwise, it will not be possible to connect the remote device to the software!

Windows

Switch on your computer and be sure to have a working Bluetooth interface active. Then, follow the step described below, taking into account that screenshots can vary from one Operating System version to another and from the Bluetooth hardware installed:

1. switch on the DT1 remote device and be sure that the red led blinks;
2. on your pc, look for a device named DT1 using the Bluetooth interface. Depending on your Windows version, you may have different windows, but in general they should be very similar to the following:

Windows Vista / Windows 7

1. select Start -> Control panel -> Hardware and sounds;
   
2. click on Add Bluetooth Device;
   

Windows XP

1. select Start -> Control panel;
2. in the control panel window, select Bluetooth  Devices;
3. in the new window which opens, click the Add... button;
4. in the Add Bluetooth Device Wizard check the My device is set up and ready to be found option and click the Next button;
3. in the new opened window, wait for the Bluetooth devices research, untill an icon named DT1 or Free2move WU appears;
   
4. double click on the DT1 or Free2move WU icon;
   
5. when requested, insert the Passkey code for Pairing to the value: 0000 (four zeroes);
   
6. click the Close button;
   
7. in the Control Panel, select Show devices and printers or Bluetooth Devices;
8. in the list, select the DT1 icon, click with the right mouse button on it and select the Properties voice in the curtain menu;
9. in the Properties window, select Services;
10. wait for the name of the serial connection to appear in the list and copy the serial port number;
11. close all the windows you eventually opened following the above steps and execute the software.

MacOS

Switch on your computer and be sure to have a working Bluetooth interface active:

1. switch on the DT1 remote device and be sure that the red led blinks;
2. open System preferences;
   
3. click Bluetooth in the Internet and Wireless section. A new window opens;
   
4. click the + button below the list of associated devices;
5. in the new window which opens, wait for the DT1 device icon to appear, then click Continue;
   
6. the Operating System should automatically guess the correct Passkey. If not, you will be asked to specify it manually;
   
7. click Exit.
8. in the Bluetooth window, select the DT1 device from the list. Then, click on the settings button and select the Change serial ports... voice in the curtain menu;
   
9. in the new window which opens, copy the serial port name (which in the example figure is tty.DT1-SerialPort). This name should be pasted to the serial port setting;
   
10. Click Apply, then close all the opened windows.

First execution

At first start, a dialog window is shown (figure 1) asking you to provide:

• serial number - the numeric code placed at the top of the Dental Torque case;
• product key - the 25 characters alpha-numeric code (divided in 5 groups of 5) placed on the install CD, or provided by the seller.

To continue, you must provide those data, writing them in the fields. If serial number and product key are correct, the OK button is enabled. Click on it to enable program execution.

Then, the main and a dialogue window (notifying lack of Dental Torque system connection) will be shown. Click Ok and set the serial port.

ATTENTION: product key chars can be both upper case and lower case. Be careful to write them correctly.

Uninstall

In order to remove DT1 instructions reported in next paragraphs, for different operating systems, must be followed.

Windows

Through control panel, go to Add/remove programs and remove DT1 from the program list. Alternatively, go to the C:\Programmi\DT1\ folder and run unins000.exe.

MacOS

Remove DT1.app from the system (move it to the bin).

Configuration and use

In figure 2 a screenshot of the Windows main window is reported, that is however very similar of that of Mac environment. We can discern the main graphical components:

• A - menu bar, through which it's possible to access to the remote device's session, print, connection tools, graphic visualization option and this manual;
• B - session and print tool bar;
• C - remote device's connection and data memorization tool bar;
• D - session area;
• E - implant file cards;
• F - implant area - where graphic, used product's info, anatomic sector, limit torque, notes and execution time are reported;
• G - acquired data area - where battery charge level, actual torque and max peak recorded are reported;
• H - average area

Note that it is possible, pressing mouse's right button and selecting the context menu voices, to activate/deactivate the tool bars. It is also possible, by dragging with mouse, to move the bar aside or to application bottom.

In general, all the software functionalities are activated only when it is possible to execute the connected actions. For instance, start, pause and zero set-up buttons can be activated only when a connection to the remote device is established. Besides, to prevent erroneous button clicks or to inform the user about potential lack of data, many dialog windows for the more critical operations are provided.

All DT1 functionalities are described in next sections.

Connection and disconnection

In order to store torsion values detected by remote device it is necessary to connect it to DT1 software. A blue led on remote device and a green icon on the tool bar indicate a correct connection.

The remote device is:

• automatically connected - at software start the remote device is searched and, if found, connected.
• automatically disconnected - in order to save energy, after 5 min. of inactivity (no data transmitted from remote device) the connection is interrupted.
• automatically disconnected - after software closure the remote device, if connected, is disconnected and shut down after a few seconds.
• manually disconnected - selecting the Tools -> Device -> Connect/Disconnect menu or pressing mouse onto the referring button located on the tool bar.

After connection, all set-up related to the actually operating implant are sent to the remote device.

Licence and serial port set up

At anyone moment - except during remote data memorization - it is possible to set-up the licence of use and the serial port associated to the remote device. In order to this, select Tools -> Settings. A dialogue window will appear, in which you should type the password given you by the software distributor (otherwise contact him).

ATTENTION: the program will be closed whenever a wrong password in entered more than 3 consecutive times. Anyway, in this case it is possible to save any open work and re-execute the application.

If password is successfully inserted, a new dialog window will appear (figure 3) where it is possible to specify the serial port connected to the remote device and your company name. If you are working with Windows operating system, digit serial port number without the sequence of characters "COM"; if you are working with MacOS operating system, digit serial port name without the sequence of characters "/dev/".

Example:

Press the Ok button and try to connect. The inserted values are recorded by DT1 software in all the next executions.

NOTE: serial port change is stored during set-up, but it will be applied only at connection opening. So, serial port modification when connection is active does not produce any connection modification.

Continuous connection

The remote device is programmed such a way that it shuts-off if no modification arises for 5 minutes time. For a perpetual active connection, also for long periods of inactivity, you may use Tools -> Device -> Always on option or pressing the analogue button in the tool bar.

NOTE: connection remains perpetual until DT1 software is working.

ATTENTION: when remote device is continuously active, its battery is more rapidly discharged.

Battery level

The approximate remote device's battery charge level is shown in the lower central part of the window. It is thus possible to better evaluate its duration and to plan for its recharging.

Sessions and implants

DT1 organizes data in sessions, each containing:

• the operator's name;
• the patient's name;
• one or more implants.

Implant characteristics

An implant is defined by (see figure 2 for a graphical view):

• used product code;
• used product lot;
• anatomic sector where to implant;
• torque threshold value (Ncm);
• allowed tolerance value;
• data acquired by remote device;
• max memorized torque value (Ncm);
• notes relevant to the implant;
• storing start date and time.

Besides these, also the graphic characteristics are stored.

NOTE: the date format is "day-month-year".

In next paragraphs we will see how sessions and relevant implants can be used.

Session creation

As soon as DT1 is started, an empty session is shown. Then, after session modification, it is possible to start from the beginning a new one.

1. select File -> New, or press the analogue button in the tool bar.

ATTENTION: starting a new section all data previously stored are overwritten. Nevertheless, a dialog window will warn that a danger can arise, allowing to save the old data.

Session modification

Modification of an active session is possible in the following ways:

• typing, in its relevant box, the operator's name (this name is recorded in all next executions);
• typing, in its relevant box, the patient's name;
• adding or removing an implant;
• modifying one of previous implants;
• storing data acquired by the remote device.

Current session save

DT1 allows to store sessions as csv files, to give the possibility to re-load later, or to analyze data with other tools like spreadsheets.

1. select File -> Save, or press the analogue button in the tool bar;
2. in the folder navigation window, select the folder where to save and give a name to the session file.
3. click Save.

Loading a session

It is possible to load data of a previously saved session, in order to be able to restore it after unforeseen causes (blackout, etc.):

1. select File -> Open, or press the analogue button in the tool bar;
2. in the folder navigation window, select the session file;
3. click Open.

NOTE: DT1 controls session file's contents in order to prevent (yet not guarantee) manumissions.

ATTENTION: it is possible to modify the loaded session, knowing that all data previously stored will be overwritten. Nevertheless, it is possible to add a new implant and operate with the same setup.

Adding an implant

In the implant file cards (figure 2) all implants are listed followed by a file card named "...". In order to add a new implant:

1. click on the last file card.

A new file card will be initialized before "..." to represent a new implant. The name of the new file card will be "Imp" followed by implant's sequence number.

Removing an implant

Each file card in the implant file cards (figure 2) has an "X" button aside the file card name. In order to delete a file card from the list:

1. click on the "X" button of the file card.

All the remaining file cards will be renamed in order to maintain the sequence of numbers filled up from 1 until the total number of implants.

ATTENTION: it is possible to delete any implant. Nevertheless, a dialog window will ask confirmation if the implant contains data.

Implant selection

In order to view (and modify) an implant:

1. select the file card corresponding to that implant.

If the remote device is already connected, its values will be automatically updated.

Implant modification

In order to modify set up values of an implant, select the implant and insert:

• product code - select one from combo box, or digit a new code;
• product lot - select one from combo box, or digit a new batch;
• anatomic sector - select one from curtain menu;
• threshold torque - it is advisable to modify such value with remote device disconnected;
• tolerance value - can be modified varying the relevant counter;
• notes - digit notes in lower right box, many lines disposable.

NOTE: you can modify the implant set up even after remote data memorization.

ATTENTION: it is firmly suggested to modify the threshold value only with remote device disconnected. Such a way interaction with graphical interface is more efficient and you do not risk to send wrong data to the remote device. As soon as it is connected, the device will be automatically set up with the values shown in the graphical interface.

Besides, starting data memorization, it will be modified:

• the data acquired by remote device - visible as a curve in the graphic and automatically updated;
• max torque memorized - updated automatically during remote data memorization;
• date and time - are automatically set up when memorization starts.

Remote data memorization

DT1 handles each implant separately. Thus, you can memorize the data acquired with the remote device in separate file cards (see figure 2). After having selected an implant and filled it with all the necessary information, it is possible to begin the data acquisition, eventually pausing it, until the end of the operation. Finally, you can select an arbitrary set of graph points (for instance those corresponding to the highest loads) and automatically compute their average.

ATTENTION: it is recommended to deactivate any screen-saver, or other energy saving setting. Otherwise, your computer may disconnect from the remote device even when data memorization is on, resulting in data loss.

Reference value (zero) set up

As default, the remote device is programmed in order to read zero value when no load is applied. Nevertheless, it is possible to modify such a reference, or to set up again whenever wrong data are seen, operating this way:

1. connect remote device to DT1;
2. lay remote device on a plane, without any knock;
3. click Zero button and wait remote device acoustic signal.

NOTE: zero value is a remote device characteristic and influences data acquisition of all the implants.

NOTE: modifying zero value does not modify already acquired data.

Start

Clicking the Start button, the remote device data acquisition is activated. Furthermore, the button icon is replaced with the Stop one.

NOTE: it is not possible to start the data memorization if the remote device is not connected.

NOTE: it is necessary that the implant is configured in its main voices. Otherwise, the memorization will not start, showing and explaining message.

ATTENTION: if the current implant contains acquired data, these will be overwritten with the new ones. A dialog window will warn you anyway.

Pause

Clicking the Pause button, the data memorization can be suspended, or, in case it has already been suspended, resumed.

ATTENTION: if the connection with the remote device is not continuous, the latter will automatically switch off after a few minutes.

Stop

Clicking the Stop button, the data memorization is temporarily suspended, showing a dialog window. Furthermore, the button icon is replaced with the Start one.

ATTENTION: it is firmly suggested not to use the Stop button to suspend the data memorization. Instead, use the Pause button.

ATTENTION: to allow for acquired data certification, once stopped the data memorization cannot be resumed.

Average

When the data memorization is stopped, it is possible to select an arbitrary set of the graph points and compute their average in the following way:

1. click the Average button placed in the central part of the main window under the graph. The computing of the average value will be activated and the average value zeroed;
2. press the Shift key and select the desired graph points. At every mouse click, the nearest curve point to the current mouse position will be selected;
3. click again the Average button. The average value computation will be stopped, while its value will be visible in the display under the Average button.

NOTE: it is possible to use the zoom to ease the desired point selection.

Data erasing

In case of memorization wrong start, it's possible to stop and eliminate all acquired and viewed data. To do this, select Tools -> Graph -> Clear data. For safety, a dialogue window will ask you confirmation.

ATTENTION: unless previously saved, session's data will be lost.

Accuracy of displayed data

As default, torsion values (Ncm) are viewed with one decimal point accuracy. To change for reading without any decimal point you must deselect Tools -> Data -> Show decimals. This setup will be maintained also in next program executions.

Graphical visualization

The graph is located in central section of the graphical interface (figure 2): here the Torque vs. Time curve, measured by the remote device, is shown in real time. This graph visualizes the data coming from the selected implant. Different implants have different graphs.

Besides it is possible to customize the aspect of the graph, as described in next paragraphs.

Torque curve color selection

The color can be changed this way:

• choosing one of the pre-defined colors listed in combo box (see figure 2);
• choosing a non-pre-defined color, pressing on the last element of the combo box and selecting among the colors that appear in the dialog window.

The chosen color is associated to the selected implant, such that different implants can be associated to different colors.

Torque curve thickness selection

The thickness can be changed this way:

• choosing one of the three pre-defined thickness listed in the Tools -> Graph -> Line thickness menu;
• pressing one of the three key combinations Ctrl+1, Ctrl+2, Ctrl+3.

The chosen thickness will remain the same for all implants.

Torque curve style selection

The style can be changed this way:

• choosing one of the four pre-defined styles listed in Tools -> Graph -> Style;
• pressing one of these keys F1, F2, F3, F4.

The chosen style will remain the same for all implants.

Zoom

The graph can be zoomed as you like operating this way:

• zoom in - press and hold pressed the mouse's left button, from the initial to the final point of the area to be enlarged;
• zoom out - press the mouse's right button in any point of the graph area .

The chosen zoom is associated to the selected implant, such a way that different implants can be associated to different zooms.

Print

The software allows to print the session on a printer (if installed) or on a pdf file. In particular, each implant is printed in its own page, reporting:

• operator's name (or personal doctor);
• patient's name;
• the company name (as set in the licence field);
• software serial number;
• graph with memorized data, with selected zoom level;
• implant execution date;
• anatomic sector where implant has been located;
• used product code;
• used product lot;
• max memorized torque value (Ncm);
• notes relevant to the implant.

NOTE: notes can be written in max four rows, the exceeding will be ignored.

Print preview

1. select File -> Print preview;
2. in the preview window it is possible to modify wrong borders;
3. in the preview window, press the print button.

NOTE: in preview, lines may appear thicker respect to the printed aspect.

Direct print

1. select File -> Print or click the analog button in the tool bar;
2. proceed in printing interacting with next dialog window.

Print in pdf format

1. select File -> Print as pdf;
2. in the explorer window, indicate folder and file name.

Language

The software has multi-language support. In particular, it is possible to obtain translation of the graphical user interface and the prints in one of the following languages:

• English
• Italian

Language selection

To switch to English language:

• select Strumenti -> Lingua -> Inglese;

To switch to Italian language:

• select Tools -> Language -> Italian;

All the terms are automatically translated in the chosen language.
