A system comprising a handpiece and drive system configured to removably couple to a proximal end of a housing. A scalpet assembly is configured to removeably couple to the housing, and includes a scalpet array comprising at least one scalpet configured for rotation. The scalpet array is configured to harvest dermal plugs via fractional resection. A collection chamber is configured to collect the dermal plugs, and to house formation of an injectable filler by mincing the dermal plugs, and mixing the dermal plugs with a carrier. The injectable filler is configured for bulk fill. The collection chamber includes a loading port, and a cannular syringe is configured to mate with the loading port to receive the injectable filler, and to deliver the injectable filler for the bulk fill.

Disclosed are applicators and methods injecting of a liquid anesthetic into a dental patient with no or minimal pain. In accordance with one embodiment the applicator is for intraligamentary injection and includes an elongated, thin member having an open distal free formed of a resilient and somewhat conformable material suitable for producing a substantially fluid-tight interface with the anatomic structures at the gingival sulcus to inject the anesthetic therein. In another embodiment the applicator includes a flexible skirt surrounding a sharpened cannula, with the cannula being movable with respect to the skirt. The skirt is arranged to receive the anesthetic to anesthetize the gum, whereupon the cannula can then pierce the gum to inject the anesthetic into the underlying anatomic structure.

An intraosseous tack device is configured to puncture alveolar bone or other human or animal bone at a targeted site of the mouth or body to provide an access point for the delivery of local anesthesia or other medicament. The device includes a tack having a head member and an elongate member extending from the head member. The elongate member is inserted into a sleeve, and the sleeve is coupled to a handle. At least a portion of the sleeve is collapsible, so that when a compressive force is applied to the head member of the tack, the sleeve partially collapses to a shorter length, allowing the distal end of the tack to pass out of the opposite end of the sleeve for puncturing the alveolar bone at the targeted site.

The present invention provides a curved needle design which deflects to an advantageous angle when inserted within the medial posterior soft tissue of the patient lower jaw. The deflected needle tip is more perpendicular to the vertical wall of the posterior ramus and promotes the needle tip contacting bone proximate to the inferior alveolar nerve prior to injection of anesthetic. The needle design also improves the tactile feedback to the dental practitioner as the needle penetrates tissue and contacts bone.

An oral appliance and a method of making the oral appliance for delivering a medicament to an oral cavity are provided. The method comprises forming a non-porous material into a portion of the oral appliance; and applying a porous material to one or more discrete regions of the portion of the oral appliance to make the one or more discrete regions of the oral appliance porous thereby forming the oral appliance.

A laser and a minimally invasive dental surgical procedure using the laser to stimulate periodontal tissue formation.

The present invention discloses a negative-pressure oral apparatus capable of relieving discomfort of soft tissues in the oral cavity and improving fixation of the oral apparatus to prevent the oral apparatus from falling off due to mouth opening. The oral apparatus is compact and elastic so that it fits various shapes and sizes of the oral cavity and is easy to be put on and taken off to provide convenience and safety to the user. In another embodiment, a method for maintaining a negative oral pressure and collecting liquid by coupling the oral apparatus to a liquid collecting apparatus capable of effectively providing the oral cavity with a negative pressure to expel liquid in the oral apparatus and deliver the liquid to an absorbing element in the liquid collecting apparatus so as to prevent liquid leakage or contamination.

Disclosed is a system for providing artificial saliva. The system can include the mouthpiece, a portable supply unit, and a stationary supply unit. The portable supply unit can be adapted to be carried by a user. The portable supply unit can include a first fluid system, a first interface module, and a first control module. The first fluid system can be adapted to fluidly couple to the mouthpiece.
