  • Patent number: 9687327
    Abstract: The present invention includes apparatuses and methods for making a final hybrid prosthesis to be attached to one or more dental implants. One preferred method includes the step of making a temporary hybrid prosthesis and at about the same time also making a duplicate temporary hybrid prosthesis. The duplicate temporary hybrid prosthesis permits the final hybrid prosthesis to be made with fewer visits to a restorative dentist and with less dental laboratory time than is currently needed when making a final hybrid prosthesis.

  • Patent number: 9687315
    Abstract: A dental pliers and method for loosening teeth from an underlying bone and gum. Pivotally connected handles which each include a user grasping portion. The first handle terminates in an arcuately extending beak exhibiting a narrowed blade edge. The second handle terminates in an opposing pad support with an ergonomic configuration substantially matching that of the patient's gum line. Upon positioning the support along a buccal location at or below the gum line, and upon aligning the beak in abutting fashion against a lingual surface of a tooth, the pad support defines a center point of rotation proximate to an edge location of the gum line and bone. The handles are subsequently rotated in an outward fashion away from the patient's gum line to separate the tooth and its roots from the patient's gum line and bone.

  • Patent number: 9655503
    Abstract: The present invention describes a dual sided dental instrument for use in intraoral photography. Each side of the dental instrument forms a different surface providing the user the capability to use a single device for differing functions.

  • Patent number: 9655691
    Abstract: A dental appliance for positioning a patient's teeth includes a removable orthodontic tooth positioning appliance having teeth receiving cavities shaped to directly receive at least some of the patient's teeth and apply a resilient positioning force to the patient's teeth. The appliance includes a hard polymer layer having a hard polymer layer elastic modulus disposed between a first soft polymer layer having a first soft polymer layer elastic modulus and a second soft polymer layer having a second soft polymer layer elastic modulus. The hard polymer layer elastic modulus is greater than each of the first soft polymer layer elastic modulus and the second soft polymer layer elastic modulus. At least one of the first soft polymer layer and the second soft polymer layer has a flexural modulus of greater than about 35,000 psi.

  • Patent number: 9655688
    Abstract: A dental instrument device includes a middle body with two ends, a pair of removable instrument tips, a pair of securing collets, and a pair of removable end caps. Each end of the middle body terminates in a middle body/instrument tip connection interface that receives a right-handed instrument tip only in a first orientation and a left-handed instrument tip only in a second orientation differing from the first orientation. The removable instrument tips have a similar middle body/instrument tip connection interface, and a working instrument end with a right-handed or a left-handed orientation. A right-handed instrument tip is releasably connected to the first middle body/instrument tip connection interface, and a left-handed instrument tip is releasably connected to the second middle body/instrument tip connection interface, with the right-handed and left-handed orientations being visually distinguishable one from the other by casual observation of an ordinary observer.

  • Patent number: 9655689
    Abstract: A dental forceps for removal of rear molars having first and second handles which are pivotally connected. Forward distal ends of the handles terminate, respectively, in a first handle support with an end most pad exhibiting a three dimensional and rounded surface profile extending laterally to one side, as well as a second handle terminating in a correspondingly angled beak. The arrangement of the pad and beak are such that, upon setting in position at the desired molar by placing the rounded and width extending pad support upon the gum of the patient between the molar and the cheek and concurrently placing the pointed beak on the lingual side of the molar, an outward rotating force is then exerted on the handles to roll (or rotate) the pad and beak such that the molar is forcibly extracted.
