Developed more than a decade ago by Dr. Gary Schoenrock of the Midwest Dental Evaluation Group, the laminar technique reportedly produces a fast, extraordinarily accurate impression that significantly reduces the need for later crown adjustments.
While the patient holds centric, a flowable wash is injected into a double-arch primary impression through holes drilled in the buccal.
This just-published article (authored by Dr. Rodger Kurthy of Mission Vieno, CA) discusses the application of several modern materials that were not available when the laminar technique was originally developed. Written for dentists new to the laminar technique as well as those thoroughly experienced with it, the heavily illustrated, eight-page article demonstrates the step-by-step procedure, and offers numerous clinical hints.
According to the author, the marriage of the laminar approach with these new materials has significantly reduced the time necessary to take an impression and has virtually eliminated seating adjustments. Total time in the mouth for both the primary impression step and the wash step combined, is slightly more than a minute. At the time this article was written, Dr. Kurthy reported 70 straight crown cementations with no seating adjustments at all.
