A modular cord-less pen-style dental instrument comprising: (a) an elongated body for gripping and holding the instrument, which has a connector portion at the distal end thereof; (b) a wand portion having a proximal end adapted to be releasably connected to the connector portion at the distal end of the elongated body; wherein the dental instrument further comprises a heat flow barrier between the elongated body and the wand portion.

A tip element (1) preferably for a dental treatment device, in particular a scaler, wherein the tip element (1) performs an ultrasonic vibration during its utilization, comprising—a first end section (10) for reversibly attaching the tip element (1) to a hand piece, a second end section (20) forming a dental tool and—a motion transformation section (30) arranged between the first end section (10) and the second end section (20), wherein, for transforming an ultrasonic vibration having a first vibration direction (V1) to an ultrasonic vibration having a second vibration direction (V2), the motion transformation section (30) has a first bended subsection (31) and a second bended subsection (32).

A medical ultrasound device includes: an ultrasound generator and an elongated probe. A cross-sectional surface of the probe at a distal end to which ultrasound oscillation is propagated is perpendicular to a longitudinal direction of the probe, and the cross-sectional surface has a shape identical to a shape of a cross-sectional surface of an anchor to form, in a bone, a bottomed hole for placing the anchor and having a shape to prevent rotation of the anchor in the bottomed hole. An area of the cross-sectional surface of the probe at the distal end is larger than an area of a cross-sectional surface of the probe at a proximal end. The distal end includes a treatment portion that expands outward relative to the proximal end and that is formed in a first direction perpendicular to the longitudinal direction and in a second direction different from the first direction.

A dental handpiece includes a cylindrical outer body, an insert body that includes an ultrasonic vibrator, and is accommodated in the outer body, a front end portion of the insert body and a rear end portion of the insert body, a tip connection portion that detachably holds a scale tip to which ultrasonic vibration from the ultrasonic vibrator is transmitted, and a cleaning liquid flow path that guides a cleaning liquid supplied from a cleaning liquid injection port of the insert body to a front end portion of the outer body. The cleaning liquid flow path includes an immersion flow path in which the insert body is immersed in the cleaning liquid in the outer body and the cleaning liquid in which the insert body is immersed is discharged from the front end portion of the outer body.

A dental surgery guide system for use with a dental handpiece for forming a bore in a patient's jaw bone to receive a dental implant comprises a surgical template and a handpiece jig; the top of the handpiece guide can slide below the top of the template guide rail.

A vibration type removal apparatus 2 includes a housing 10, a holding member 11, a tool 12, a control device 20, a vibration device 21, and a cooling pump 22. The control device 20 drives the cooling pump 22, and cooling water supplied from the cooling pump 22 passes through a flow path 25 in the housing 10, and is sprayed toward the tool 12 from a distal end of the flow path 25. In this state, the tool 12 is inserted between a hard tissue HT and a soft tissue ST, the vibration device 21 is operated, and the tool 12 is vibrated. Due to the vibration of the tool 12, a surface of the hard tissue HT which adheres to the soft tissue ST is cut, and the hard tissue HT is peeled and removed from the soft tissue ST.

An ultrasonic tip, attachable to an ultrasonic handheld instrument for vibrational energy, and method for treating peri-implantitis by removing a thin layer of the surface of the contaminated metal implant base that is exposed from the loss of osseo-integration due to bacteriological biofilms. The ultrasonic tip includes a narrow wire shaft body having at its distal end a concave abrasive diamond-coated tapered grinder plate with a front grinding surface, tapered in thickness from top to bottom, that can be manually pressed against an exposed implant base vertical cylindrical diseased surface while the grinder plate is vibrated ultrasonically to remove a thin layer of the titanium alloy metal implant base. The ultrasonic tip narrow wire shaft body has three bends to avoid the crown when manually positioning the grinding surface of the grinder plate to ensure manipulation the grinding surface by the periodontist. A detoxicant liquid is introduced during cleaning to enhance removal of diseased material by vibration of the liquid to penetrate microstructural surface areas of the implant base.
