A cortical drill for hydrating and drilling cancellous bone when preparing a dental implant includes a stem portion and a drill portion, the stem portion with a locking notch and a water inlet configured for receiving fluid under pressure into the cortical drill. The drill portion has an elongated substantially conical body having an outer wall. The drill portion has a slot portion, and the slot portion includes a cut-out forming an inlet along a peripheral surface of the conical body. A plurality of jets are formed in the slot portion, with the jets in communication with the water inlet, and the jets arranged along the slot portion, such that fluid travelling under pressure into the water inlet, travels through the stem portion and the drill portion, and exits the jets in the slot portion.

The present disclosure discloses a water flosser comprises a housing, a tooth irrigation portion, a water nozzle portion, a winding mechanism, and a water pipe configured to be bent and wound. The tooth irrigation portion is disposed in the housing and comprises a water inlet and a water outlet. The water nozzle portion is in communication with the water outlet of the tooth irrigation portion.

An apparatus for performing dental hygiene includes a concave support member integrally coupled to an upper end of a handle portion, and a floss attachment coupled to the concave support member between a first end and a second end of the concave support member. A hollow passage extending from a lower end of the handle portion to the second end of the concave support member is provided, which receives a water flosser tip such that water from the water flosser tip traverses and exits from an aperture shaped end of the hollow passage at the second end of the concave support member onto the floss attachment in a direction substantially parallel to the floss attachment for the apparatus to work as a water floss pick.

A toothbrush including: a body, the body having a head with bristles; and a manually operated pump formed in the body, the pump having a nozzle for drawing a liquid into the body and expelling the water from the body. The nozzle can be disposed on the head on a surface opposite to a surface on which the bristles are disposed. The pump can further include: a reservoir disposed in the body for containing the liquid, the nozzle being in fluid communication with the reservoir; a shaft movably disposed in the reservoir, the shaft having a first seal substantially disposed at a free end of the shaft; and a second seal disposed in the body for sealingly engaging with an outer surface of the shaft. The first seal can be a piston a grip can be disposed at an other end of the shaft.

Periodontal disorders such as disorders associated with a dental implant are treated. An average power for a laser is selected via a user interface on a tablet, along with a set of permissible laser parameters provided in response to the selected average power. A gingival trough or flap is created around the implant with the laser. Infected tissue is selectively ablated or denatured via photothermolysis, and a pocket is lased around the affected implant. Marginal tissues are compressed against the implant.

An oral cavity cleaning device, which comprises a body, a water jet tip, a first motor, a second motor, a brush, and a water suction assembly. A rotating shaft extends out of an upper end surface of the body. The first motor drives the rotating shaft to vibrate to drive the brush to vibrate. The upper end surface of the body further comprises a water outlet, and the water jet tip is disposed on the upper end surface of the body and is in communication with the water outlet. Further, the water jet tip is disposed on a side of the brush facing a user, and the water jet tip is disposed below bristles of the brush. The second motor drives the water suction assembly to pump water from a built-in or external container, and water from a water passage disposed in the body sprays out of the water outlet and the water jet tip.

A water tank used for a dental water jet device includes a box and a water pipe. The box has a top and a bottom opposite to each other. An upper side of the bottom facing the top has a water guiding surface and a water collecting area. The water guiding surface extends obliquely downward from an edge of the upper side to the water collecting area. The water pipe extends from the water collecting area to pass through the top, and has a water outlet above the top. A dental water jet device having the water tank is also provided.
