The present disclosure relates, in some embodiments, to a dental prosthesis and methods of use thereof. According to some embodiments, a dental prosthesis includes a dental implant surgical guide, a prosthesis base, a prosthesis cover, at least one implant configured to be inserted through the dental implant surgical guide and the prosthesis base into a dental surgical site; and at least one implant fastener configured to attach to the at least one implant. A prosthesis base may include: a base bottom configured to sit adjacent to a dental surgical site, and a base top including a base recess, the base recess including at least one base aperture. In some embodiments, the dental implant surgical guide is configured to sit within a base recess. A prosthesis cover, in some embodiments, may include a cover recess configured to encapsulate at least a portion of the dental implant surgical guide within the base recess.

Dental attachment assemblies for a mouth of a patient are provided. Contemplated dental attachment assemblies may include an abutment member, and a retention member for attachment to the abutment member. The retention member may comprise an upper end and a continuous, unbroken skirt projecting from the upper end for fixed, non-patient removable, fixed engagement over an outer locating surface of the abutment member. The retention member can be constructed from a rigid material, such as PEEK, such that it provides a retentive force of about 10 to 75 pounds. The abutment member may be configured for attachment to an implant having an upper portion including a threaded portion configured to screw into a threaded recess of an abutment, and a lower portion including an angled platform and a threaded post extending from the platform.

The invention relates to an apparatus for releasable attachment of a removable dental prosthesis to a head part of an implant or of an abutment that can be anchored in an implant, comprising a retention matrix (1) having a receptacle that accommodates a circular-ring-shaped retention element (2) that has at least two clamping arms (22), which is disposed so as to be displaceable along a center axis of the retention matrix (1), wherein the at least two clamping arms (22) form a mantle surface that widens conically toward the outside, and that the receptacle for the retainer element (2) has two sections (14, 15) having a different inside diameter, against the transition of which the at least two clamping arms (22) lie. The invention furthermore relates to a dental implant system, having such an apparatus.

A false tooth implanting device, having an expandable implant body, a lower protruding block at a recess of a lower portion of the implant body, a vertical screw, and a lateral screw; the recess has a first slanted engaging surface; an upper portion of the expandable implant body is provided with a vertical hole and a first portion of a vertical screw hole; the lower protruding block is provided with a second slanted engaging surface in contact with the first slanted engaging surface and a second portion of the vertical screw hole; the vertical screw passes through the vertical screw hole; the upper portion of the expandable implant body is provided with an expansion crevice and a lateral screw hole; when the lateral screw is screwed into the lateral screw hole, the upper portion of the expandable implant body is widened by expanding away from the expansion crevice.

Compositions and methods for inhibiting and interrupting biofilm formation, and for destabilizing established biofilms are provided, the novel compositions including polymeric resins and monomeric non-polymerizable and polymerizable resins. More particularly, the compositions and methods enable the protection and removal of biofilms from surfaces in the context of medical, consumer, domestic, food service, environmental and industrial applications, where the effects constitute beneficial and desirable biofilm attenuating activity.

Provided is a superstructure (3) coupled to a fixture (2) that is made of pure titanium or a titanium alloy and planted in a jawbone, the superstructure (3) including: a framework (5) made of a cobalt-chromium alloy; an artificial tooth (4) bonded to the outer surface of the framework (5); and a coupling member (6) made of a gold alloy and joined to a lower part of the inside of the framework (5) to couple the framework (5) to the fixture (2), wherein the framework (5) and the coupling member (6) are integrated by being soldered together with a solder (10) composed of a gold alloy containing gold and silver.

A system and method for optimising the preparation of dental restorations is provided. The system comprises a dental restoration surface processing unit, a dental restoration assessment unit, a database comprising a treatment parameters database and a processing protocols database, a processor operationally coupled to said dental restoration surface processing unit and a protocol selector. The method treats a dental restoration surface using the system and according to one or more selected processing protocol.

In a method of planning a restorative dental treatment for a patient, at least two dental restorations are digitally constructed (20). In the process, an optimum specification (40) for the insertion of the restorations into the mouth of the patient is calculated (30), wherein the optimum specification for the insertion of the restorations comprises an optimum sequence of the restorations to be inserted; if applicable, including optimum insertion paths for the restorations to be inserted.

A dental all-ceramic restoration and manufacturing method thereof; the outer surface of the dental all-ceramic restoration has neither visible marks remaining from the removal of the connecting bars (7) nor local grinding traces and chipping, and is smooth with uniform structure. The manufacturing method thereof is wet-forming or milling. No connecting bars are needed to connect the dental restoration bodies (3) with a surrounding mould blank or ceramic blank. This eliminates the need for manually cutting off the connecting bars (7) to separate the forming body from the surrounding ceramic blank, further grinding and polishing process to treat the excessively rough outer surface, and thereby reducing the risk of chipping and premature failure. In the manufacturing processes thereof, the hardened ceramic green body (2) made by wet-forming technique has more homogenous microstructure and less particle packing defects than the dry-pressed blanks and partially sintered blanks. Furthermore, higher surface smoothness can be obtained by milling unsintered hardened ceramic green body than by milling partially sintered blanks. The dental all-ceramic restoration has a high degree of surface finish, and can be directly used without polishing, veneering or glazing.
