orthesis

— While the phthalate concentrations are low and the amounts ingested probably even lower than acceptable limits, (Corea-Tellez et al. 2008), biomedical devices made of PVC elastomers such as mouth protectors, oral ortheses worn by patients with algo dysfunction of the manducator apparatus, oral respiratory devices worn by patients with sleep apnea syndrome, etc. are placed in the mouth much more frequently by adults than PVC toys by children.
