Methods: The experimental connector was contrived to be easily constructed, inexpensive, and small for use as an intraoral MAS. To evaluate the durability of the trial MAS system, the axial and diagonal tensile breaking strengths for the MAS using high-density (HDPE) or low-density polyethylene (LDPE) lateral toothed belts were compared to those for a conventional mobile MAS (Silensor).
Results: Compared with Silensor system, the experimental MAS system exhibited sufficient breaking strength, especially when a diagonal tensile load was applied to mimic mandibular lateral translation (HDPE-polycarbonate, 81.0 N; LDPE-polycarbonate, 55.8 N; Silensor, 35.9 N).
Conclusions: The experimental connecting system is thought to have the possibility of the clinical application. To make the connector stronger for clinical use, HDPE should be selected.
