Dear Colleagues,

I am pleased to tell you that ESCO, the Electronic Study Club for Orthodontics, has resumed after an inactive period in 2003. 

Under the capable leadership of Joseph Zernik since 1995, ESCO gave thousands of orthodontists the opportunity to discuss orthodontic topics ranging from practice management to theoretical concerns.  Recently, Dr. Joseph Zernik turned over the entire day-to-day management and moderating of ESCO to the Department of Orthodontics, University of Illinois at Chicago.  In 2004 and beyond, we expect that ESCO will continue to grow in popularity and benefit the subscribers.

With best wishes for a healthy and happy new year,

Carla A. Evans, DDS, DMSC

Hello Group,

I'm glad to be back, and here goes my question. 

I have an adult lady that has implants on upper central incisors, and she came to me , to correct the lower incisors that are kind of pilled up.  Through the cephalometric and clinical analysis I can correct that by projecting the lower incisors, since she has a great overjet, about 4 mm.  My question is if there is a minimal space that should be left in this overjet being the upper implants?

Does anyone have a history, however brief, of the use of computers in orthodontics?

Dear Group,
       Are the chemicals used in direct bonding like cyno-acrylates pretty safe in the mouth as it is reacted upon by various secretions and digestive processes. We had seen a couple of Leukemia cases with bonded orthodontic appliances- might be totally unrelated, but a pinch of salt in the corner of the mind-particularly on the pungent and toxic nature of primers and cyno-acrylates ? Does anybody have a validated study report on absolute safety of these chemicals in the GIT?
