I think the approach of "Hologram" is something close to what you do mean, I think it depends on digitalized three dimensions photos, anyway it needs more "amendments" for being more worthwhile in clinical usage.

Thank you.

Regarding Dr. Retrouvey's device to digitize models, why not have a device to use in our offices to digitize impressions with software that would convert the info into nice digital models for us? No pour-ups, sending out, receiving data, etc. Anyone know of such a device and software existing now?

Dear Bert,

Could we please backtrack one step further?
How about digitising intra-orally? For use as both study and working models!
They do it more accurately in small scale for Cerek. This is used for inlays, Crowns, veneers without impressions.

Subject: OrthoII firewall compatibility

Hi All,

Anyone else getting bogged down with internet security? We use OrthoII practice management software on a small network of  4 computers. They are connected to the internet through a router and DSL modem. Each machine has Symantec anti-virus software installed. At this point there is no firewall, because OrthoII technical support said that firewalls would keep the program from communicating accross the various machines.

With the increased circulation of spyware out there, we need to add a firewall somewhere in the system. If am very interested in hearing your experiences with using the OrthoII practice management software behind a firewall. Is there perhaps a router/firewall or a software firewall solution?

Thank you,

In a small network (<10 computers), you can simply buy a router which has built-in firewall protection. Currently, most DSL/Cable network router has the ability to add some protection. There are some expensive hardware firewalls available on the market, like SOHO, but it's really not necessary to get that fancy.

Firewalls do NOT prevent spyware from getting into your computers. Preventing spyware is currently very passive, e.g.,
1. using Ad-Aware or spybot to remove them;
2. set your browser to block all third-party cookies;
3. install popup blocker such as the Google toolbar.

Hopefully, Microsoft will release their IE6 SP2 in 2 or 3 months, which has built-in spyware blocker. But who knows, just like viruses, you can never prevent them from coming, but you can block them when they are here.

The most important and efficient way to prevent attacks, viruses and spyware is to get yourself and your staffs well-informed. Some more hints on increasing the security:
1. Set your antivirus to automatic update;
2. Set your windows to automatic update;
3. Disable guest accounts on all computers;
4. Set a password for each account;
5. Backup your important information often (once a day is highly recommended)
