Thermoformed semi-rigid splint designing method for orthodontics apparatus, involves arranging thrust producing structure opposite main plane of thermoforming volume of cavity, and interfering simulation pattern by thermoforming of splint

摘要

The method involves producing a sample (7) of a malpositioned arch, and forming a model (11) of a normal occlusion arch. A unitary and unique splint (2) is thermoformed from a synthetic sheet (3), and is placed in mouth of a patient. The sample is fused, by superimposition, with the model for forming a simulation pattern (18). A thermoforming volume (20) of an insertion cavity (21) integrated to the pattern is delimited. A thrust producing structure (23) is formed and arranged opposite a main plane of the volume. The pattern is interfered by thermoforming of the splint.
