New Transference Technique of Position of Mandibular Reconstructing Plates Using Stereolithographic Models

Abstract

Stereolithographic models are commonly used to adapt reconstructive plates in patients who will undergo mandibular resection. However, the published reports have not explained exactly how to accurately transport this plate to the patient. The purpose of our report is to illustrate a new transference technique of mandibular reconstructing plates from the stereolithographic model to the patient, without the need for testing it before tumor resection. This technique involves coating the stereolithographic model with an acrylic guide that covers the dental pieces and also impresses the mandibular reconstructive plate (Fariña's splint). This firm structure, formed by the Fariña splint and the reconstruction plate, is taken to the patient after tumor resection has been performed. This technique reduces the operative time and results in the surgeon knowing in advance the exact position of the plate in the patient.
