[A custom grooved impression tray].

Individual compartment trays can be used for dental impression in fixed prosthodontics and represent an original method which alleviates the pitfalls of standard technics. This method is based upon a strict adaptation of the tray to both the preparations and the dental arcade using the primary impression. Impression pastes can be used in their optimal conditions using the I.C.T. (Individual Compartment Trays) and a higher definition of cervical limits can be obtained. The use of I.C.T. reduces the risks of interposing free marginal gingival and eliminates the inconvenients of intrasulcular leakage.
