| 20100273124 | STEADY PRESSURE DENTAL IMPRESSION TRAY AND THE IDEA OF OPERATION - An object making its impression in soft material, due to the force application, of various strength and impact directions, reproduces its parts at different heights, thus providing a distorted cast of the object. | 10-28-2010 |
| 20110129791 | SYSTEMS AND METHODS FOR OBTAINING DENTAL IMPRESSIONS - Certain embodiments of the present invention provide an apparatus to facilitate obtaining a dental impression including a compressible body. The compressible body has a top surface, a bottom surface, and an outer border. The bottom surface is configured to abut a maxillary dental impression tray. The top surface of the compressible body is configured to substantially contact and conform to a surface of a patient's hard palate. As the top surface contacts and conforms to the hard palate, it causes the compressible body to compress. The top surface forms a seal with the patient's hard palate. This seal discourages dental impression material from flowing into the patient's palatal vault. The seal may also discourage the dental impression material from flowing into the back of the patient's mouth. Consequently, the hydrodynamic pressure of the dental impression material may be advantageously increased and the patient's comfort may be reduced. Furthermore, the seal may promote a hydrodynamic flow of the dental impression material against the patient's teeth and into the corresponding gingival sulcus. When the compressible body compresses, the outer border may expand. This expansion may lead to further promotion of the hydrodynamic presser and flow of the dental impression material. | 06-02-2011 |
| 20110171592 | Method of Direct Fabrication of Intraoral Devices - A method of direct fabrication of intraoral devices provides an easy, cost effective way of making a variety of appliances intraorally.

A palatal retainer provides the primary retention for optional functional components to be incorporated. Functional components may include anterior deprogrammers, and full coverage and partial coverage occlusal guards. Use of the palatal retainer provides comfortable, safe retention without the need for excessive facial wrap. The retainer itself can function as a palatal obturator or a healing stent. Fabrication of the appliances could be performed by the end user, health care providers, or anyone skilled in the art. | 07-14-2011 |

| 20150010879 | HYDRAULIC PRESSURE BITE-DOWN DENTAL IMPRESSION - In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays: creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made. | 01-08-2015 |

| 20080280249 | Dental Impression Bite Tray - The present invention is referred to the disposable bite trays among the dental impression trays. The metallic reinforcements of the invented tray are fixed by exposing to the exterior of the connecting loops on the both sides of the impression obtaining walls. The reinforcements should include an impression obtaining membrane in the central portion, the moving freely prevention stair, and various moving freely prevention grooves. The moving freely prevention stair is to fix the plastic supporter and reinforcement together and prevent the individual movement of the supporter and reinforcement. The disposable bite trays are usually made up of plastics because they are easy-to-make materials, cheap, and convenient to use. However, no matter how strong plastics those are used, the connecting loops of the impression obtaining walls on the both sides of the tray will still be thin and narrow. It is because the connecting loops go into the inner space where maxillary and mandibular molars occlude, and so they have to be thin and narrow. In this case, the connecting loops of the impression obtaining walls can become weak and may result in twist or warp of the impression materials when obtaining the dental impression. These deformed impression materials may make difficult to obtain an elaborate teeth impression. Therefore, in the present invention, the metallic reinforcement was added to the connecting loop of the plastic tray. This will make the plastic tray rigid as a metal tray and make adjustable. For instance, dentists may be able to adjust the width of the tray or cross the impression obtaining walls. This customized tray will provide a safe disposable bite tray to obtain an elaborate teeth impression. | 11-13-2008 |

| 20090208896 | Methods and Devices for Diastema Closure - In a method for closing a diastema and/or papilla regeneration between a first tooth and a second tooth, a dental matrix is used. The dental matrix includes a curved sectional strip of material. The strip has a length from a first end to a second end sufficient to create a form for molding a restorative material to a surface of the first tooth. The strip has a root end section and a second section integral with the root end section. The root end section of the strip is anatomic in shape such that the root end section hugs the gingival portion of the first tooth. In one form, a non-anatomic bulge is formed in the second section. The root end section of the matrix can slide to the depth of the sulcus without lacerating the tissue. After inserting the root end section of the dental matrix into the sulcus between the papilla and the gingival portion of the first tooth, a composite restorative material is placed between the dental matrix and a cervical surface of the first tooth. The composite restorative material is then cured. This creates bulbousness in the cured composite near the gum line to fill the gingival gapping. | 08-20-2009 |
| 20090269715 | Spider die - For a resilient mounting of a spider die onto a dental prosthetic suprastructure on a male spider mold, at least one retention element is molded onto a sleeve, and the retention element has a substantially occlusal alignment.

| 20140199653 | HYDRAULIC PRESSURE DENTAL IMPRESSION - In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays; creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made. | 07-17-2014 |
