Programmazione ortodontica-prechirurgica tramite allestimento di mascherine termostampate

Objectives: The aim of this work is to introduce the protocol used at the Orthodontic Department of Milan University. Materials and methods: All diagnostic and laboratory steps are described. Results: The occlusal splint guides are made on a cast model after developing an orthodontic set-up. At any appointment the clinician can evaluate if the occlusal guides fit and what dental movements are necessary; this is possible without repeating records and taking new impressions. The evaluation of orthodontic treatment progression is also possible whereas undesirable effects, such as jiggling movements, can be avoided. The objectives of presurgical orthodontics are achieved when occlusal splint guides fit perfectly: at this moment the patient might be considered ready for surgery. Conclusions: The protocol described by the authors allows to obtain an accurate orthodontic planning before surgery and to optimize treatment steps with consequent advantages in clinical practice.
