Devices, kits, and methods useful in the treatment of Obstructive Sleep Apnea (OSA) are described. Example devices include a jig, a first needle, a second needle, and a third needle. An example jig comprises a drill guide and a tongue depressor. A first needle comprises an elongate shaft that defines a bend and a curve. A second needle comprises an elongate shaft that defines a curve. A third needle comprises an elongate shaft that defines a curve.

In order to make a custom dental drilling template, a single impression element is used that becomes a part of the later drilling template. To achieve this a guide-passage element is glued to the impression element. The exact position of the guide passage relative to the impression element prior to gluing is found by fixing both elements relative to each other on the same mounting plate using a periodic 2-D mounting structure. The passage element is mounted by an intermediate mounting element that is machined such that it carries the same or mating mounting structure according to positional data and that has a fitting area for fitting the guide passage to it.

An aspect of the present invention is a drill assistance device comprising: a drill guide device that serves as a guide when forming a plurality of holes from a curved surface of a hard palate having the curved surface; and a guide sleeve that is fitted in the drill guide device in an attachable and detachable manner. With this device, it is possible to easily and accurately perform the hole making with a drill and the implant of a screw in an oral cavity. The drill guide device comprises: a guide frame unit that is formed by connecting a plurality of tubular guide frames to each other; a fixing member to be capped on a tooth of a patient; a connecting portion that connects the guide frame unit and the fixing member and determines arrangement of the guide frame unit on the curved surface; and at least one protruding portion that holds the guide sleeve inserted in any of holes inside the guide frames. The guide sleeve comprises: a tubular sleeve main body having an inner diameter that allows the drill to be inserted and an outer diameter that allows the sleeve main body to be inserted in any of the guide frames; a water injection slit that is provided in the sleeve main body; and projecting portions that are each fitted in at least one recessed portion provided in the at least one protruding portion when the sleeve main body is inserted in any of the holes of the guide frames.

In some aspects, dental drill guides can include a body defining an outer surface and an interior hole for receiving and positioning a dental drill; a first end of the body defining a tapered lead-in portion of the outer surface; a second end of the body opposite the first end defining at least one lip feature configured to be gripped by a handling tool; an outer circumferentially formed recess around the outer surface; and a seating feature extending from the outer surface.

A dental laser treatment system includes a treatment laser beam and a pilot (e.g., aiming/marking) laser beam sharing a collinear beam path, where the beam path is guided by a guidance system through a handpiece/main chamber assembly having a beam exit. A laser beam presence detector is removably affixed to or within the handpiece/main chamber assembly. The laser beam presence detector provides feedback to a computer which can control actuation of the treatment laser beam and the pilot laser beam, and the beam guidance system. The computer performs a search for determining the center location of the beam exit based on the feedback and controls the beam guidance system to guide the beam path approximately to the center of the beam exit, thereby providing automatic alignment of the laser beam with the beam exit or an optional hollow waveguide.

Drills for dentistry, which, in a dental implant treatment, enables two or more holes to be bored at a predetermined angle and interval in a minute space in which a single tooth grows and enables treatment to be performed precisely and rapidly regardless of a skill level of a dentist, wherein an arrangement is provided where a first member provided with a drill body and a second member provided with a fixing needle intersect slid-ably at a predetermined angle, the drill body is installed in a direction perpendicular to an axial direction of the first member with its tip facing a direction in which the fixing needle is provided, the fixing needle is installed in a direction perpendicular to an axial direction of the second member with its tip facing a direction in which the drill body is provided, the drill body bores a first hole, bored obliquely with respect to a natural tooth growing direction, and a second hole facing the first hole mutually at a predetermined angle, and the second hole is bored by the drill body upon inserting the fixing needle in the first hole, fixing the second member to the jawbone, and sliding the first member with respect to the second member, fixed to the jawbone, as a reference.

A dental surgical drill guide assembly and method includes a surgical guide housing and a base frame that fits to both gum tissue and one or multiple small areas of jawbone. The apparatus may be configured to accurately place dental implants according to planned positions. Such apparatus may increase the stability of the surgical guide by clasping and/or contacting the jawbone, while improving the overall fit and minimizing the need of invasive surgery and flapping by also clasping and/or contacting selected areas of the gum tissue at the same time. Self-locking alignment members aid in easy removal, and re-installation, of the surgical guide housing to the base frame.

In some aspects, dental drill guides can include a body defining an outer surface and an interior hole for receiving and positioning a dental drill; a first end of the body defining a tapered lead-in portion of the outer surface; a second end of the body opposite the first end defining at least one lip feature configured to be gripped by a handling tool; an outer circumferentially formed recess around the outer surface; and a seating feature extending from the outer surface.

A dental implement is disclosed that includes a proximal end portion; a distal end portion that includes a cutting head defining at least one cutting surface; and a guide body that is positioned proximally of the cutting head. The guide body defines at least one flute that extends in generally parallel relation to a longitudinal axis of the dental implement and is configured to direct irrigation fluid to a surgical site within a patient.
