Subject: Bonding Porcelain

From: "Claude Matasa <Matasa@AOL.COM>"

Dr. I Gillis has shown that he is successfully bonding porcelain by applying first two layers of a silane the nature or concentration he doesn't describe. Coupling agents supposes to form a monomolecular layer so that each part of their molecule bond another substrate. Applying two layers, you may either have the chance of covering exactly the areas which have remained untreated, which I doubt, or lay two or more layers. In the last case the silane acts rather like an oil, prohibiting a good bond between substrates.

Subject: New educational materials available from The Angle Society


The Edward H. Angle Society of Orthodontists ( EHASO ), the non-profit organization that sponsors The Angle Orthodontist, announces two new contributions to advance orthodontic education and research:

  1. A new film about the founder of modern orthodontics, Edward H. Angle, available on DVD for purchase.
  2. A 3400-page four-volume book set reproducing Dr. Angle's correspondence and business accounts from 1899 to 1910, and including facsimiles of all 47 of his patents.

The Angle DVD

Angle, Lukens, Knapp, Canning, Korbitz, Pfaff, Farrar, Guilford and Jackson were well-known 100 years ago for their “systems” of appliances to straighten teeth. Today, why do we know only the name Angle from among this forgotten group? The legacy of Dr. Edward H. Angle has endured on the strength of his inventive genius and powerful influence in the worldwide development of modern orthodontics.

A biographical film “Edward Hartley Angle: the life of a visionary” premiered in 2005, the 150th anniversary of Dr. Angle's birth, to acknowledge his trailblazing accomplishments in orthodontics. He was the first dentist in the world to limit his practice to “orthodontia” exclusively (1892), the first to set up a specialty program in orthodontics (1900), the first to organize a society of orthodontists (1901) and the inventor of a succession of ingenious biomechanical systems that culminated in the edgewise appliance (1925) which is a key orthodontic mechanism used today.

This memorable movie (52 minutes) is available on DVD, ideal for anyone interested in orthodontics and for educational programs. The price is US $25, which includes North American shipping and handling (outside North America, US $30 including airmail). Only USA checks, VISA or MasterCard are acceptable.
