A guide for guided surgery on zygomatic bone implants for dental prostheses includes a half-bushing and a complementary half-bushing which are connected by a pair of bars. The half-bushings and the bars define a common longitudinal median axis between them; the half-bushings have a U-shaped or semicircular cross-section with mutually opposite concavities directed toward the median axis; the half-bushings and the bars form a seat in which it is possible to insert a work member, such as a burr and a subsequent implant, which can move only along the median axis and rotates about an axis of rotation that coincides with the median axis.

The disclosure relates to methods for attaching a dental implant surgical guide and a dental implant to a dental surgical site including: assembling an implant combination, positioning the dental implant surgical guide including a double open-ended guide cylinder at the dental surgical site; rotating the implant combination through the double open-ended guide channel; and attaching a cap comprising a hollow cylinder to the double open-ended guide channel so the rim of the implant mount body is sandwiched between the dental surgical guide and the cap. The disclosure further relates to a dental prosthesis apparatus including: an abutment; a dental implant; a dental implant surgical guide including a first and a second double open-ended guide cylinder connected by a support bar; an implant mount including a rim; and a cap operable to engage the dental implant surgical guide and sandwich the rim between the cap and the dental implant surgical guide.

An implant surgical guide apparatus includes a bone pen which is standardized by various diameters based on mesio-distal distances of natural teeth so that an implant can be placed at the center of a prosthetics, and comprises a cup having a rotatably symmetrical shape and a pen coupled to the cup and drilling into an alveolar bone so that the implant can be guided to a position with an angle as desired by an operator when the implant is placed in the alveolar bone corresponding to tooth loss.

A system is disclosed for installing a dental implant in a jawbone of a patient. The system includes a threaded drive shaft rotatable about an axis and guide means for supporting the drive shaft with its axis oriented in a path along which the implant is to be installed. The guide means has a threaded bore for receiving a drive shaft and an opening which extends parallel to the axis of the drive shaft and opens radially outwardly from the bore. The drive shaft can then be engaged with and disengaged from the guide means by radial displacement of the shaft parallel to its axis. A drill is adapted to be releasably coupled to a leading end portion of the drive shaft and may be a self-drilling implant. Means is provided for rotating the drive shaft in a direction to cause the drill to penetrate the jawbone of the patient.

The invention could comprise a bone foundation guide system and a method for same, the bone foundation guide system having a bone foundation guide comprising a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site, the body being further contoured accept and to guide the cutting of a portion of the bone segment from a dental implant surgical site and as well as to alternatively support a dental implant surgical guide; the dental implant surgical guide; and a bone foundation guide prosthesis as an alternative to the dental implant surgical guide, the bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

A drill limit system includes a holder having drill stops removably coupled thereto and configured to receive a drill bit therethrough, and a platform coupled to the holder and configured to engage a tip end of the drill bits when received through the drill stops, wherein the holder and platform are movable relative to each other so that the position of the drill stops relative to the drill bits may be selectively varied. A method for attaching drill stops to a drill bit includes providing a holder and a platform movable relative to each other, the holder having a plurality of drill stops removably coupled thereto, inserting a plurality of drill bits through respective drill stops, moving the holder and platform relative to each other to select a desired height of the drill stops on the bits, and engaging the drill stops to the drill bits at the selected height.

A method is provided including shaping a thermoplastic material on a dental arch of a subject and utilizing the shaped thermoplastic material to facilitate inserting of a steerable implantable neural stimulator into a greater palatine foramen of the subject. The method further includes advancing the stimulator through a greater palatine canal of the subject to a sphenopalatine ganglion (SPG) of the subject. Other applications are also described.

A bone foundation guide system having a bone foundation guide with a foundation guide body forming an open surgical space connecting a top of the bone foundation guide body with a bottom of the bone foundation guide body, the bottom contoured to removably affix the bone foundation guide body to the bone of a dental implant surgical site, the body further contoured to guide the cutting of bone from a dental implant surgical site and supporting a dental implant surgical guide; the dental implant surgical guide contoured to removably mate to the bone foundation guide body; wherein a combination of the bone foundation guide and the dental implant surgical guide forms a double open-ended placement channel that passes through a plurality of guiding cylinders held in tandem alignment to aid in the placement of a dental implant that is anchored in a site remote from the mouth.

A drill guide assembly used to guide a drill into the jawbone of a patient during dental surgery includes at least one through going guide bore for guiding the drill, at least one attachment for securing a part of the drill guide assembly to the jaw of the patient during surgery, wherein the drill guide assembly includes a first part including the at least one first through going guide bore, the at least one first attachment and at least a first reference area for referring the first part to a first anatomical feature of the patient, a second part including a second reference area for referring the second part to a second anatomical feature of the patient, and a guiding structure for guiding the first part and the second into a desired configuration.

A drill limit system includes a holder having drill stops removably coupled thereto and configured to receive a drill bit therethrough, and a platform coupled to the holder and configured to engage a tip end of the drill bits when received through the drill stops, wherein the holder and platform are movable relative to each other so that the position of the drill stops relative to the drill bits may be selectively varied. A method for attaching drill stops to a drill bit includes providing a holder and a platform movable relative to each other, the holder having a plurality of drill stops removably coupled thereto, inserting a plurality of drill bits through respective drill stops, moving the holder and platform relative to each other to select a desired height of the drill stops on the bits, and engaging the drill stops to the drill bits at the selected height.
