| 20080220050 | Compositions For Gingival Retraction And Other Methods - At least one clay, at least one glass filler, and at least one astringent agent are formulated with water into a paste for injection in dental and medical applications. In one embodiment, the paste is used to treat and/or widen a gingival sulcus. The paste is readily rinsed off the surface to which it is applied using water. | 09-11-2008 |
| 20090042170 | GINGIVAL RETRACTION WITH LIGHT CURABLE COMPOSITION - A method for temporarily widening a gingival sulcus. A composition comprising a polymerizable monomer having at least one ethylenically unsaturated group, a photo polymerization initiator, and a fine inorganic powder is inserted within a gingival sulcus to be widened, and the composition is thereafter irradiated in situ to polymerize the composition. The result is a rubbery material that is easily removable from the widened sulcus. | 02-12-2009 |
| 20090093563 | DENTAL ADHESIVE AND METHOD OF USE - A dental adhesive composition comprising (i) at least one non-acidic polymerizable monomer having at least one ethylenically unsaturated group, (ii) optionally one or more acidic compounds, (iii) at least one photoinitiator, (iv) at least one solvent, and (v) about 0-40% by weight of one or more fillers; wherein the weight ratio of non-acidic polymerizable monomers/acidic compounds in the adhesive composition is more than about 4.5; the viscosity of the adhesive composition is less than about 350 centipoise (cP) at 25° C.; and the adhesive composition excluding solvent and filler has an acid number of less than about 0.75 mmol NaOH/g. The dental adhesive composition is used with a dental primer composition, which may be provided together in a kit. | 04-09-2009 |
| 20090176194 | METHOD OF CEMENTING PROSTHETIC DEVICES AND CEMENTATION KIT - A simplified method for adhering a prosthetic device to tooth structure using a single-part light-curable self-adhering cement composition. The method includes adhering a bonding surface of the prosthetic device to tooth structure directly using a light-curable single-part self-adhering cement composition without first treating the tooth structure and the bonding surface of the prosthetic device with a primer/adhesive, and photo-curing the cement composition. The light-curable single-part self-adhering cement composition comprises: (i) at least one acidic polymerizable monomer having at least one acidic moiety and at least one ethylenically unsaturated group, (ii) at least one non-acidic polymerizable monomer having at least one ethylenically unsaturated group, (iii) at least one photo-initiator, and (iv) at least one filler. The weight ratio of component (i) to component (ii) ranges from about 0.5:99.5 to about 70:30. | 07-09-2009 |
| 20100041786 | SINGLE-PART, LIGHT-CURABLE, SELF-ADHERING DENTAL RESTORATIVE COMPOSITION AND METHOD OF USING THE SAME - A dental restorative composition comprising: (A) polymerizable monomer(s) having at least one phosphorus-containing acidic moiety and at least one ethylenically unsaturated group; (B) polymerizable monomer(s) having a molecular weight of 100-250, at least one hydroxyl group, and at least one ethylenically unsaturated group; (C) polymerizable monomer(s) having a molecular weight of 270-900, at least two ethylenically unsaturated groups and no acidic functional group; (D) photo-initiator(s); and (E) filler(s) each having a mean particle size of more than 0.005 microns and less than 70 microns. The weight ratio of (A+B):(C) ranges from 30:70 to 90:10, the concentration of (A) is 10-50 wt. %, the concentration of (B) is 15-60 wt. %, and the composition has a shear bond strength of at least 10 MPa to both dentin and enamel. Also provided is a method for filling a dental cavity with the composition without first treating the dental cavity with an etchant, a primer and/or an adhesive. | 02-18-2010 |
| 20100248190 | METHOD OF USING DENTAL COMPOSITION - A method for temporarily widening a gingival sulcus is provided using an uncured composition comprising a polymerizable monomer having at least one ethylenically unsaturated group, a photo polymerization initiator, a fine inorganic powder, and an astringent. The uncured composition is inserted within a gingival sulcus to be widened, and the composition is thereafter irradiated in situ to polymerize the composition. The result is a rubbery material that is easily removable from the widened sulcus. | 09-30-2010 |
| 20100278998 | ONE-COMPONENT DENTAL ADHESIVE COMPOSITIONS AND METHOD OF USE - A one-component self-etching self-priming dental adhesive composition is disclosed. The composition comprises glycerol phosphate di(meth)acrylate monomer, at least one mono-functional polymerizable monomer having just one ethylenically unsaturated group, at least one multi-functional polymerizable monomer having at least two ethylenically unsaturated groups, at least one aprotic solvent, at least one protic solvent, and at least one polymerization initiator. | 11-04-2010 |
| 20110217677 | SINGLE-PART, LIGHT-CURABLE, SELF-ADHERING DENTAL RESTORATIVE COMPOSITION AND METHOD OF USING THE SAME - A dental restorative composition comprises: (A) polymerizable monomer(s) selected from hydroxyethyl (meth)acrylate phosphate, hydroxypropyl (meth)acrylate phosphate, hydroxybutyl (meth)acrylate phosphate, dipentaerythritol penta(meth)acrylate phosphate, pentaerythritol tri(meth)acrylate phosphate, phenyl (meth)acryloxyethyl phosphate, and a combination thereof; (B) polymerizable monomer(s) having a molecular weight of 100-250, at least one hydroxyl group, and at least one ethylenically unsaturated group; (C) polymerizable monomer(s) having a molecular weight of 270-900, at least two ethylenically unsaturated groups and no acidic functional group; (D) photo-initiator(s); and (E) filler(s) each having a mean particle size of more than 0.005 microns and less than 70 microns. The weight ratio of (A+B):(C) ranges from 30:70 to 90:10, and the composition has a shear bond strength of at least | 09-08-2011 |
