Abstract
A method and apparatus for anchoring flaps of tissue in the body utilizes panels of material including a plurality of outwardly extending quills, or pins, to engage and secure the flaps of tissue in place.
Claims5
A method for coronally repositioning the gingiva, comprising the steps of
- (a) separating a first gingiva flap from the bone on the inside an alveolar bone ridge supporting teeth in the mouth, said ridge having a peak;
- (b) separating a second gingiva flap from the bone on the outside of said alveolar bone ridge, said second flap generally being opposed to said first flap;
- (c) positioning a first quill member intermediate said first flap and said bone ridge, said quill member including a pliable panel of material having a back and a front surface and including a plurality of gingiva piercing pins attached to said panel and outwardly projecting from said front surface, said quill member being positioned intermediate said first flap and said bone ridge such that said back is against said bone ridge;
- (c) pressing said first flap against said quill member such that said pins pierce and engage said first flap;
- (d) positioning a second quill member intermediate said second flap and said bone ridge, said second quill member including a pliable panel of material having a back and a front surface and including a plurality of gingiva piercing pins attached to said second quill member and outwardly projecting from said front surface of said second quill member, said second quill member being positioned intermediate said second flap and said bone ridge such that said back of said second quill member is against said bone ridge;
- (e) pressing said second flap against said second quill member such that said pins of said second quill member pierce and engage said second flap;
- (f) coronally pulling said first flap and second flap toward said peak of said bone ridge by interconnecting said first and second quill members with a length of suture which extends over said peak and upwardly pulls said quill members toward said peak.
A method for grafting pink gum tissue to gum tissue adjacent alveolar bone, comprising the steps of
- (a) preparing a donor site by removing gum tissue to expose underlying periosteal tissue;
- (b) harvesting from the palate a piece of donor tissue shaped to be placed on the donor site;
- (c) placing said donor tissue on the periosteal tissue at said donor site;
- and,
- (d) anchoring said donor tissue to the gum tissue adjacent said donor tissue by pressing a quill member against said donor tissue and said adjacent gum tissue, said quill member including a pliable piece of material and a plurality of pins attached to and extending outwardly from said piece of material, said pins piercing and engaging said donor tissue and said adjacent gum tissue when said quill member is pressed against said donor tissue and said adjacent gum tissue.
A method for securing a second layer of soft tissue in a body in a selected position with respect to a first layer of soft tissue in the body, comprising the steps of
- (a) pressing a quill member against said first layer of soft tissue, said quill member including
- a piece of material having a front side and a back side spaced apart from and opposing said front side,
- a plurality of pins attached to and extending outwardly from said front side of said material and shaped and dimensioned to pierce said first layer of soft tissue, and
- a plurality of pins extending outwardly from said back side of said material and shaped and dimensioned to pierce said second layer of soft tissue,
- said pains extending outwardly from said front side piercing said first layer of soft tissue when said quill member is pressed against said first layer;
- and,
- (b) pressing said second layer of soft tissue toward said piece of material and against said plurality of pins extending outwardly from said back side of said material to pierce said second layer with said pins extending from said back side of said material such that said second layer extends over said first layer.
A method for securing a piece of material to soft tissue in a body, said piece of material (110) having a front side and a back side and a plurality of soft tissue piercing pins (111) attached to said piece of material and extending outwardly from said front side such that said pins (111) are canted in a selected direction (J) with respect to said front side, said method including the steps of
- (a) pressing said tissue piercing pins and said soft tissue together such that said pins pierce said soft tissue and said front side of said piece of material contacts said soft tissue;
- and,
- (b) tensioning said soft tissue to force portions of said soft tissue toward said canted pins in a direction (K) opposite said selected direction (J).
A method for securing a second layer of soft tissue in a body in a selected position with respect to a first layer of soft tissue in the body, comprising the steps of
- (a) placing said first layer and said second layer of soft tissue adjacent and side-by-side one another;
- (b) interconnecting said first and second layers by pressing a quill member against said first layer and said second layer of soft tissue, said quill member including a piece of material extending from said first layer to said second layer and including a plurality of pins attached to and extending outwardly from said piece of material, said pins piercing and engaging said first and second layers of soft tissue when said quill member is pressed against said first and second layers.
