An abutment is provided with a screw access hole and a slot in its sidewall adapted to allow a driver to access a screw in the screw access hole at an angle relative to a longitudinal axis of the screw. The abutment may include a screw seat and may be connected to an implant via a screw in the screw seat. A prosthesis, which may include a driver access channel that has a diameter less than the outer diameter of the drive portion of the screw, may be placed over the abutment. Methods of making a dental prosthesis and methods of attaching and removing the dental prosthesis from the implant are also disclosed.

Apparatus and method for installing a multi-tooth dental prosthesis in one session are shown and described. A first tool attaches to the jawbone, and serves as a foundation for subsequently used guides. Existing teeth and dental fixtures are removed, and the bone tissue is removed to accommodate the prosthesis. Subsequently, a drill guide is used to drill implant holes. An abutment guide is then used to place abutments. Copings are then installed. Next, the prosthesis may be installed and cemented to the copings. A resinous filler material may be applied to fill gaps and holes in and between the copings and the prosthesis, and is sanded smooth.

A method for designing a dental prosthesis and a positioning guide for placing the dental prosthesis on implants in the jaw while maintaining proper occlusion relates to designing the dental prosthesis and the positioning guide prior to implant placement.

Disclosed is a method for manufacture of a removable dental prosthesis by moulding, the method including: digital modelling of a prosthesis model; a step of producing a mould including a lower half-shell corresponding to a tooth part of the prosthesis and an upper half-shell corresponding to a gum part of the prosthesis, the two half-shells being able to be joined together by affixing one to the other, thereby forming an impression of the prosthesis, the step including digital modelling of a model of the mould, followed by additive manufacture of at least the lower half-shell, and a step of producing the prosthesis, the step including in succession at least one provision of at least one artificial tooth, positioning of the artificial tooth in a seat of the lower half-shell, assembling the mould and pouring a filler material into the mould. Also disclosed is a prosthesis obtained by this method.

The overdenture holder device includes a holder abutment in which a through insertion portion is formed to be opened in both directions of a body portion having a bottom end portion inserted into a top end of the fixture and protruding upward and a fastening hole penetrates along a longitudinal direction and has an inner circumferential side on which a holding step protruding radially inward is formed, a fastening screw having a bottom end portion inserted into the fastening hole to be screw-coupled with the inside of the top end of the fixture and a head portion formed at a top end portion and to be held by the holding step, and a pressurizing device coupled with a top end of the body portion and configured to provide a pressurizing force such that an outer surface of the fixing bar is fixed to an inside of the through insertion portion.

A device for enhancing the appearance of a person's lips is formed from a curved member configured to fit between the person's upper or lower lip and an adjacent gum at the front of the mouth. The curved member has a gingival portion configured to be placed on the person's gums, a top surface and an extension connected to the top surface and extending from a longitudinal edge of the top surface to overlap and extend beyond the gingival portion. The extension is configured to rest against and evert the person's upper or lower lip when the device is placed between the lip and the person's gum.
