FIELD: process engineering.SUBSTANCE: claimed invention relates to mould for production of tooth thread holder. Claimed mould is intended for production of tooth thread throwaway holder comprising tooth thread section with wax composition applied thereon. Note here that said mould comprises first part including its first cavity. Note also that said first cavity confined by bottom base surface and outer side wall includes the base and first and second parts spaced apart and including proximal and distal sections extending from the base. Second part includes second cavity arranged therein. Note also that said second cavity confined by bottom main surface and outer side wall includes the base and first and second parts spaced apart and including proximal and distal sections. Note that said parts extend from the base to reach the distal section. Besides, it includes first and second end sections as well as central section. Note that the groove extends over the second part width. Note also that first and second end sections of said groove intersect and are aligned with distal section of the first and second spaced apart parts. Note that this groove features width-to-depth ratio between geometrical sizes of 10:1 or higher.EFFECT: better sliding of thread between teeth, care of gingival.11 cl, 6 dwg, 9 tbl |
