A dental implant includes an implant body with a coronally open cavity as well as at least one exit opening from an inside to the enossal outer surface. A thermoplastic element in the solid condition is arranged in the cavity or is introducible into the cavity and can be brought into an at least partly flowable condition by way of applying a pressing force, which is directed apically into the cavity, and mechanical oscillations and in this condition at least a share of the flowable material of the thermoplastic element can be pressed through the at least one exit opening into surrounding bone tissue on account of the pressing force, when the implant body is arranged in an opening in the bone tissue and the enossal outer surface is in contact with the bone tissue.

A process for providing a sterilized dental article, at least a portion of the surface of which exhibiting a contact angle of less than 45. The process includes the subsequent steps of a) providing a dental article and b) subjecting the initial dental article to a hydrogen peroxide plasma treatment. It is characterized in that the hydrogen peroxide plasma sterilization treatment of step b) is carried out in the presence of a carbon-containing compound, which during treatment is converted to form a carboxylic group attached to the surface of the dental article.

A System of Triple abutments with Tconnect comprising T-abutments to place at least three dental crowns over a one only osseointegrated implant and only one T-abutment, for partial fixed cases and new total fixed segmented cases, T-Over abutments with Plug T for use of overdentures over only one abutment and only one osseointegrated implant too, T-healing for guide specific gingival contour of the Tconnect in the healing phase and T-guides, to guide the implant surgery to be positioned for the use of abutments of this system. The all abutments of this system has Tconnect, being an exclusive design support with paraboloid multidimensional contour in double shape curvature with three pins disposed in the form of a tripod (in triangular arrangement) and are adaptable to all the implant/abutment fitting connections of market. All system may be individualized, make in process type CAD-CAM or prefabricated (manufactured type) and it can receive any type of surface treatment. The new biomechanical possibilities of the invention provide stability, passivity, greater precision of adaptation and better distribution of tensions, a fundamental advantage for use of the immediate load. The soft tissue is favored by immediate loading too. The new fixed arrangements with segmentation promotes cleaning and longevity for the system. This invention provides superior resistance of the abutments, long-lasting esthetic and reduction of the bone grafts, clinical time and costs, ensuring predictability of the results.

Disclosed is a dental implant with a post element that can be inserted into a jawbone and with a mounting element attached to the post element, to which mounting element and dental element can be affixed with the post element designed as a ceramic body of yttrium and/or aluminum oxide stabilized zirconium oxide. Said dental implant should have an even additionally improved ingrowth or integration behavior during the osseous implant healing, compared with the mentioned known concepts. According to the invention, the surface of the dental implant is provided with at least one partial area that has nanoscopic pore or an otherwise executed nanoscopic structure that has a depletion zone with a reduced yttrium and/or aluminum oxide element, compared with the internal volume.

A dental implant including a core; at least one screw thread; a first and second region; a central axis; the surface of the core defining an angle with the central axis in the first region and with the central axis in the second region; and the surface of the screw thread defining an angle with the central axis in the first region and with the central axis in the second region. The diameter of the core decreases at a rate in the first region towards the apical end such that the core defining angle is greater than the screw thread defining angle, and the diameter of the core decreases at a rate in the second region towards the apical end such that the core defining angle is the same as the screw thread defining angle. Furthermore, an implant including at least one helical chamber including a depth and length.

A biological tissue rootage face (30) capable of closely bonding to a biological tissue (H, S) is composed of a biocompatible material and has numerous fingertip-shaped microvilli (41). The microvilli (41) have tip diameters in the order of nanometers. An implant (1) has the biological tissue rootage face (30) on a surface (11, 24) configured to root into a biological tissue (H, S). In a method for forming the biological tissue rootage face (30), a surface of a biocompatible material is subjected to laser nonthermal processing carried out by emitting a laser beam in air, to form numerous fingertip-shaped microvilli (41). The laser beam is a laser beam of an ultrashort pulse laser.

A predetermined bone site in a patient selected for restoration is exposed, contacted with an aqueous, methylene blue containing phosphoric acid solution for a time period of at least 3 minutes but no more than about 15 minutes, and thereafter cleansed ultrasonically to remove any bacteria that may be present. Preferred phosphoric acid concentration in the aqueous solution is about 37 percent by weight.

Described herein is a method of preparing a bone graft product, comprising computer-guided precision cutting an unshaped piece of bone from a human cadaver or a bovine animal to provide a shaped piece of bone having a predetermined shape that is determined by a human being using computer-aided design. Bone graft products prepared using this method and methods of grafting these products are also disclosed.

Dental implants, dental abutments, and dental systems are disclosed. A dental implant can include an implant body having a longitudinal axis, a coronal end, and an apical end. An internal bore can be provided within the implant body, and can have a coronal end, adjacent to the coronal end of the implant body, and an apical end. The internal bore can include a first internally facing surface, extending from the coronal end of the internal bore towards the apical end of the internal bore, at least a portion of which tapers inwardly towards the apical end of the internal bore. The internal bore can further include an internally threaded portion positioned between an apical end of the first internally facing surface and the apical end of the internal bore. A dental abutment can be configured to engage with the dental implant.

A dental implant, extending along a first longitudinal axis between a proximal end and a distal end, includes a proximal endosseous section designed to be buried in the patient's jawbone, extended away from the proximal end by a distal implant section designed to emerge from the patient's jawbone, and an inner connection housing extending from the distal end towards the proximal end. The distal implant section extends at a height along the first longitudinal axis towards the distal end from a base to an apex, and flares from the base to the apex away from the first longitudinal axis. The base has a diameter smaller than a diameter of the proximal endosseous section, so as to form a first annular groove. The distal implant section includes an outer surface having a roughness less than or equal to 0.2 m. The height at which the distal implant section extends from the base to the apex is between 1.2 mm and 1.5 mm.
