Abstract
An orthodontic band having a textured inner surface for enhancing the adhesive bonding to a tooth, wherein the textured surface is formed by photoetching a pattern of pockets, indentations, or raised portions.
Claims27
Metal band material adapted to be cut into circular blanks and die-worked for making tubular orthodontic bands, said material being in flat sheet or strip form of a thickness such that it will function as an orthodontic band when die-worked into a tubular band and being photoetched on one side which becomes the inside surface of the band and the side to be engaged by dies during die-working into tubular bands, and said photoetched side including a plurality of spaced apart indentations each having a centrally disposed island, whereby said indentations coact with cement when attaching the band to a tooth with a dental cement to materially enhance the strength of the cement bond between the band and the tooth.
A seamless orthodontic band having an inside surface, said band being die-worked from metal band material having said inside surface photoetched to define a textured surface for materially enhancing the strength of bonding the band to a tooth with cement.
A seamless orthodontic band for attaching an orthodontic appliance to a tooth comprising, a metal die-worked ring-shaped body having a smooth exterior side to which an orthodontic appliance may be attached and a textured internal side for bonding to the tooth, said internal side being textured by being photoetched with a pattern of pockets and die-worked such as to distort the pattern and cause at least some of the pockets to have undercuts, thereby materially enhancing the bonding strength between the band and the tooth.
A metal blank of thin stainless steel for forming a ring-shaped orthodontic band from a series of dies, said blank being circularly shaped and having a thickness of about 0.006 inch, the outer side of the blank being smooth and the inner side being textured, said textured side being photoetched with a plurality of pockets in aligned rows.
A metal ring blank of thin stainless steel for forming a ring-shaped orthodontic band from a series of dies, said blank being circularly shaped and having a thickness of about 0.006 inch, the outer side of the blank being smooth and the inner side being textured, said textured side being photoetched with a plurality of doughnut-shaped recesses in aligned rows.
A metal blank of thin stainless steel for forming a ring-shaped orthodontic band from a series of dies, said blank being circularly shaped and having a thickness of about 0.006 inch, the outer side of the blank being smooth and the inner side being textured, said textured side being photoetched with a plurality of pockets in staggered rows.
A metal ring blank of thin stainless steel for forming a ring-shaped orthodontic band from a series of dies, said blank being circularly shaped and having a thickness of about 0.006 inch, the outer side of the blank being smooth and the inner side being textured, said textured side being photoetched with a plurality of doughnut-shaped recesses in staggered rows.
Metal band material for making tubular orthodontic bands to be attached to a tooth with a dental cement, said material being in flat sheet or strip form and being photoetched on one side which becomes the inside surface of the band, and said photoetched side including a plurality of rows of spaced apart pockets, Whereby said pockets coact with the cement when attaching the band to a tooth to materially enhance the strength of the cement bond between the band and the tooth, said pockets in inches being about 0.0085 by 0.0085 with a depth of about 0.001 and a spacing between pockets of about 0.005.
A metal blank of thin stainless steel for forming a ring-shaped orthodontic band from a series of dies, said blank being sized and shaped to be die-workable into a band and having a thickness of about from 0.005 to 0.007 inch, the outer side of the blank being smooth and the inner side being textured, said textured side being photoetched with a plurality of rows of pockets.
