  • Patent number: 11723702
    Abstract: The invention discloses a modular surgical bone screw assembly having a threaded base portion and a screw head adapted to attach a variety of structures to bone. The features of the screw include a modular design for the assembly that separates the function of anchorage to the recipient bone to one of the modules of the device (threaded portion) from the other function of attaching another element (such as bone block, membrane, orthodontic wires, elastics etc) to a second module (the screw head). The design also allows the head to be exchanged after the implant has been placed.

  • Publication number: 20230181293
    Abstract: The extraction socket devices are designed to protect the extraction socket immediately after tooth extraction. These devices protect the socket from oral bacteria and food, support a space to prevent collapse of the alveolar ridge during healing, contain any bone graft material inside of the socket, and provide comfort to patient during the healing process. Procedures are also disclosed for placing the devices in an extraction site to obtain the benefits of the disclosed devices.

  • Publication number: 20210386502
    Abstract: The present invention is a group of surgical instruments with improved function and design for dental and craniofacial surgery, especially subperiosteal tunneling and related procedures. The instruments include surgical elevators for vestibular incision or incisions in the gingival sulcus. The instruments have varying angles and shapes to create a mucosal tunnel in any oral or maxillofacial region. The instrument suite also optionally includes specially designed forceps for introduction of graft material inside the subperiosteal tunnel and to assist with suturing of the graft to surrounding tissue.

  • Publication number: 20130122052
    Abstract: The invention relates to the field of immunologically reactive molecules used to improve implantable medical devices. Immobilization of selected antibody molecules onto the surface of medical implants enable localization and concentration of in vivo growth factors in a timely manner to enhance the wound healing process following implantation of the device. When in vivo BMP-2 growth factor was captured on an implant device by attached monoclonal antibodies, the biological activity of BMP-2 was enhanced in the vicinity of the implant device. BMP-2 growth factor-specific antibody molecules or their fragments when immobilized on titanium dental or orthopedic implants improve osseo-integration.

  • Publication number: 20130123774
    Abstract: A series of tips for use with an ultrasonic or piezoelectric dental surgical device dental are used in osteotomy, ostectomy and osteoplasty procedures or any procedure requiring removal or shaping of bone or other hard tissues. In some embodiments, fissures are provided in a cutting end of the tip to facilitate osteotomy. The tips are shaped so that they are comfortable for the surgeon to use in a proper position, so that when a handpiece to which the tips are releasably attached is held in the conventional manner, the geometry of the osteotomy will be precise and desirable. When energized, the tips readily cut through bone or facilitate shaping of skeletal structures at the surgical site. Methods for use of the tips and systems in which the tips provided the cutting function are also described.

  • Patent number: 7494812
    Abstract: An adoptive immunotherapy using ex vivo-generated regulatory T cells may be used for the suppression of undesireable immune response. T cells are to be obtained from the patient's blood, and upon exposure to a set of toxins from the pathogen A. actinomycetemcomitans, the population of regulatory T cells will be enriched ex vivo and adoptively transferred back to the patient. The novel aspect of the present invention is that it generates large numbers of type 1 regulatory T cells, which secrete Interleukin-10.
