0 Thermoplastic substances can be melted and formed into shapes that become hard, and can then be melted again.
Thermoplastic cradles must tie up to patient bony pelvis anatomy, yet lateral tattoos are tied in with alignment marks drawn on the cradles.
The domain selected for experimentation was the conceptual design of thermoplastic components.
Epoxies, which are thermoset polymers, do not melt when heated (as opposed to thermoplastics).
Based on clinical experience, this author notes that anteriorly encasing thermoplastic cradles pose additional technical problems.
Within a few days, a thermoplastic shell was moulded using standard pre-cut material and the simulation session repeated.
Repositioning accuracy of a commercially available thermoplastic mask system.
Two types of vacuum-formed shells, and eight thermoplastic systems have been evaluated.
However, some patients may have more movement than others such that conventional immobilisation with thermoplastic shells may be inadequate.
