  "abstract": "The present invention is a dental implant tool comprising of a handle and a head portion connected to each other via a hinge facilitating the head to pivot relative to the handle to enable the dentist to reach various positions within a patient's mouth. The head portion configured to retain an abutment, an impression coping or healing abutment during a dental procedure and can be moved to the left and the right up to 90 degrees. The head comprises a rotatable ratchet with a key-shape center hole to hold an abutment in place while affixing the abutment to an implant and provides a complete access to implant-driver tip to the screw head, regarding to any abutment-body angulation, position and screw access hole. The inner wall of the center hole has 3°-degree convergences at any plan of the walls in order to grasp, lock and hold implant abutments. The dental tool provides practitioners with a better and more enhanced access to the sites of the implants without any limitations, regarding to the implant while minimizing the amount of health risk exposure through increasing the level of safety standards.",
  "claims": [
    "1. A dental tool for installing a dental abutment, and impression coping, or a healing abutment, comprising: a) a head having a distal end and a proximal end for holding a dental abutment, an impression coping, or a healing abutment wherein said head comprising: i) an aperture at the distal end to receive a ratchet; ii) the ratchet has a keyhole-shaped aperture with an inner wall, wherein said keyhole-shaped aperture has a circular section and a stem section and wherein the inner wall convergences from an upper surface towards a lower surface of the ratchet to grasp and hold the dental abutment, and iii) a locking mechanism to fix and lock the ratchet in said aperture; b) an elongated handle pivotally and rigidly connected to said head from the proximal end at a pivot point and wherein said head moves 90 degrees to a right side or a left side; whereby the dental tool provides a secure access for a screw to an implant-driver tip for any abutment-body angulation and position.",
    "2. The dental tool of claim 1, wherein the inner wall has 3°-degree convergences.",
    "3. The dental tool of claim 1, wherein the locking mechanism comprises of a knob slidably movable by a lever in communication with a plurality of grip retaining gaps extended continuously around an outer side wall of the ratchet to rotatably and firmly grasp the ratchet.",
    "4. The dental tool of claim 1, wherein the elongated handle is selected from the groups consisting of a straight body, a curved body or a combination of straight body and curved body.",
    "5. The dental tool of claim 1, wherein the elongated handle has a length in the range of about 5 cm to about 7 cm.",
    "6. The dental tool of claim 1, wherein said dental tool or said head are replaceable.",
    "7. The dental tool of claim 1, wherein the dental tool is made of medical titanium alloy or stainless steel.",
    "8. The dental tool of claim 1, wherein said dental tool further has a pair of heads, a first-head and a second-head.",
    "9. The dental tool of claim 8, further the elongated handle has a first connection point and a second connection point, which the first-head connected to the first connection point, and the second-head connected to the second connection point, and the second-head is in a predefined distance to the first-head for installing two dental abutments at a time.",
    "10. The dental tool of claim 8, wherein the elongated handle further has a slot which the second-head is slidably moveable in the slot."

  "description_excerpt": "The present invention relates in general to the field of implant dentistry and in more particular to a set of instruments which includes features that should provide an improvement to the underlying procedure in the implant dentistry as well as matters pertaining to patient safety.\n\nDental implants have been widely used for single-tooth replacements up to full-arch rehabilitations. The long-term predictability of Osseo-integrated oral implants is well documented. A dental implant system consists of an implant that is surgically implanted in maxilla or mandible (upper or lower jaw), and an abutment that mates with the implant once the implant successfully Osseo-integrates to the bone. Depending on the specific system used, an abutment can include a machined connection mechanism within itself or can be clamped onto the implant by means of an abutment screw. The dental prosthesis is then fabricated over the abutment.\n\nTo perform this procedure there are many small parts/particles e.g. healing abutments, impression coping and abutments to fix the implant and its components. During dental-implant procedure, those small parts may fall into patient's mouth or throat. This is a common incidence due to the small size of the parts, slippery and lubricated environment by saliva and unwanted movement of patient's tongue.\n\nThe fallen objects may pass through two routes; either through food passage or air way passage. Ingestion of artificial crowns and small implant particles such as abutments, impression coping, healing abutment and screwdriver accounts for major share of accidental swallowing by patients.",
