Rapid Prototyping as an Adjunct for Autotransplantation of Impacted Teeth in the Esthetic Zone
Volume 49 : Number 11 : Page 711 : Nov 2015
Autotransplantation of teeth, introduced by Slagsvold and Bjercke more than 40 years ago, is a proven option either for substitution of missing teeth or for replacement of avulsed and traumatized teeth when the original donor teeth are available. In cases of severely impacted teeth, it can avoid the need for complex traction mechanics and the risks of side effects on adjacent teeth while reducing overall treatment time. The procedure requires viable periodontal ligament cells around the tooth to be transplanted. It is also technique-sensitive, necessitating proper preparation of the recipient site, in the exact size and shape of the donor tooth and root, to minimize the time the donor tooth remains outside the oral cavity during surgery.

The iMolar System and Clear Aligners in Adult Class II Patients
Volume 57 : Number 1 : Page 45 : Jan 2023
The iMolar system consists of a base anchored by two palatal miniscrews and attached to nickel titanium wires with crimpable stops. As Dr. Riatti and colleagues show, it can be activated and modified for molar distalization while clear aligners are performing dental alignment.
