FIELD: medicine.
SUBSTANCE: dental flask refers to dental orthopaedics and can be used for making overdentures. The dental flask comprises a demountable body in the form of a lower bath and an upper pressure bath symmetrical to each other and pressed together by a thread connection. The upper bath is provided with a receiving gate and a demountable pressure bottom. Notches for side gates are formed along the periphery of the lower bath and the upper pressure bath. Upper gates are formed in the corners of the demountable pressure bottom. The lower bath is provided with a demountable bottom connected by pins and clamp nuts to the demountable pressure bottom.
EFFECT: presented flask provides accurate, processible and cost-efficient production of both overdentures at the same time by injection moulding.
