A hydrogel for use in oral care. The hydrogel is ion beam cross-linked, the hydrogel is adapted to be disposed in the oral cavity and may be adapted to provide a denture fixative or may be loaded with a whitening agent for use in whitening one or more teeth and disposed on or adjacent one or more teeth and the whitening agent is slow-released to whiten the one or more teeth. Other loading materials may include materials for treatment of alveolitis or malodor, inter alia. The present invention is a new hydrophilic oral and dental cohesive hydrogel sheet designed to securely grip and cushion prosthetic devices in the human mouth with the further ability to slow release antimicrobial or other orally desirable agents. Additionally, the invention also provides a method of making an orally cohesive device that: 1) is easily adapted and applied to a removable dental prosthesis; 2) bonds well to alveolar ridge/palatal mucosa and denture acrylic materials; and 3) releases cleanly, with no tacky or thixotropic residue when the prosthesis is removed. The cohesive hydrogel gel device is a hydrogel-forming polymer mixed with water, optionally surrounding an internal scrim, and uses an electron-beam energy source to cause cross-linking. The method does not need any chemical additive to affect the cross-linking. Furthermore the beam energy can be adjusted to optimize the cohesive properties of either side of the device, as well as to compensate for addition of orally active agents, if any are chosen. The hydrogel sheets are pre-cut to fit most sizes of maxillary and mandibular full denture prostheses, but can be easily trimmed with a scissors by the end user for the ideal custom fit of any full or partial denture, in either arch.

The invention relates to a complete dentition full denture finished product resin tooth, which comprises an upper denture, a lower denture, an upper dentition and a lower dentition, wherein the upper dentition is fixedly connected with the upper denture; the lower dentition is fixedly connected with the lower denture; and the upper dentition and the lower dentition are engaged with each other and are integral dentitions respectively.

Each tooth is arranged according to an inclination angle in the tooth arrangement standard and positional relation of each dental cusp and an occlusal plane; the upper dentition and the lower dentition are matched teeth and are centrally engaged without error basically; the chair-side occlusal adjustment time of the full denture is reduced; the treatment time is shortened; and the comfort and the satisfaction of patients are improved.

An exemplary virtual facebow system comprises a software program which is run on a tablet or other portable computing device with a microprocessor, an internal memory component, an image capture device, and a display screen. The virtual facebow system is used to record characteristics of the occlusal arch of a patient including, but not limited to, the midline of the patient's face, the steepness and cant of the occlusal arch, as well as a record of which maxillary (upper) teeth make contact with which mandibular (lower) teeth. The recorded characteristics are then used to replicate the alignment of the patient's occlusal arch with the maxillary cast in a lab stand, and the maxillary cast can then be moved to an articulator for the production of customized dental prosthetics for the patient including, but not limited to, restorations and partial or full dentures.

Tunnel bone grafting according to the proposed method can be used when an individual has a facial bone defect due to periodontal disease, cleft palate or trauma. The proposed method can be utilized for implant placement, it reduces wrinkles and supports facial muscle in order to make the individual look younger. The method can also be used to create a thicker alveolar ridge in order to stabilize full dentures or partial dentures. Its advantages over conventional guided bone regeneration techniques is that the proposed method is minimally invasive and lessens trauma to patients, prevents soft tissue opening, and reduces surgery time. Specifically, it minimizes the incision size and thus reduces trauma to the patient. Further, this reduces the risk of complications, including excessive bleeding, due to the minimization of the incision size. There is also considerable reduction in post surgery swelling using the proposed method as opposed to conventional techniques.
