  • Patent number: 10327870
    Abstract: Methods and devices for subperiosteal minimally invasive aesthetic ridge augmentation and reconstruction, including of the mandible and maxilla. Implementation of procedures that manipulate the tissue to accept an implantable article are carried out. The reconstruction or augmentation involves selecting a surgical site at which an implantable article is to be installed, making one or more incisions in the tissue remote from the selected site, developing a tunnel leading to the site, forming a pouch under the periosteum at the site, and positioning an implantable article, such as a bone graft, in the pouch using the tunnel as the passageway. Implementations may include forming a customized bone graft to address a specific defect, and providing specially configured instruments for use in carrying out the method.

  • Patent number: 10314493
    Abstract: A plaque detection apparatus (70) and method make use of an excitation source (72), a light detector (74) and a controller (76). The excitation source (72) outputs wavelength modulated light (?ex) to an evaluation site (80) that has a periodically changing wavelength centered around a wavelength corresponding to a non-linearity in an absorption and/or a fluorescence excitation spectrum for a chosen plaque. The chosen plaque exhibits spectral characteristics different from non-chosen plaque and/or interfering species. The light detector (74) detects light (?site) (84) received from the evaluation site (80), including site reflected light (?refl) and/or site emitted light (?em). The controller (76) operatively couples to the excitation source (72) and the light detector (74) for controlling the excitation source to output the wavelength modulated light and detecting plaque as a function of the detected light (?site) and at least one higher harmonic of the wavelength modulation frequency.

  • Patent number: 10299887
    Abstract: The provision of dental restorations can be improved by generating a cold atmospheric plasma inside the mouth of the patient and then applying that cold atmospheric plasma onto a dental restoration site. The dental restoration site can be composed of either or both of dentin and enamel. Further, the provision of dental restorations can also be improved by introducing a dental adhesive onto a dental restoration site and treating it with a cold atmospheric plasma.
