Abstract:
1. A dental shaping strip comprising: a base portion having a first base surface and a second base surface facing in an opposite direction from the first base surface, the first and second base surfaces having prescribed longitudinal lengths and prescribed widths transverse to the prescribed longitudinal lengths, the prescribed longitudinal lengths being larger than the prescribed transverse widths; a shaping portion connected to a longitudinal edge of the base portion, the shaping portion having a first shaping surface connected to the first base surface on a common side of the dental shaping strip, with at least part of the first shaping surface being abrasive; and a holding portion extending from a longitudinal edge of the shaping portion spaced from the base portion, the holding portion having a first holding surface extending from the first shaping surface on the common side of the dental shaping strip, the first and second base surfaces being at least partially non-abrasive, the first shaping surface and the first base surface diverging from each other as the first shaping surface extends away from the longitudinal free edge of the base portion of the dental shaping strip, as viewed in transverse cross-section along a longitudinal direction of the dental shaping strip, such that the first shaping surface is obtuse relative to the first base surface, and the holding portion and the shaping portion diverging from each other as the holding portion extends away from the longitudinal edge of the shaping portion, as viewed in transverse cross-section along the longitudinal direction of the dental shaping strip, such that the first shaping surface is reflex angled relative to the first holding surface.
