A method of positioning a dental implant in a jaw bone using a piezoelectric cutting tool is provided. Ultrasonic vibration is generated with the piezoelectric cutting tool. The piezoelectric cutting tool is translated in a lateral direction to form a first cut into the jaw bone and to form a second cut into the jaw bone. The second cut intersects the first cut to define a multi-slotted aperture in the jaw bone for receiving at least one dental implant. The dental implant is inserted in the multi-slotted aperture from the lateral direction.

A dental drill system for use in preparing an osteotomy of a predetermined depth and diameter sized to receive a dental implant therein is disclosed. The drill system comprises at least one elongate depth drill of a first diameter adapted to drill the osteotomy opening to the predetermined depth, and at least one elongate width increasing drill of a second greater diameter adapted to size the diameter of the osteotomy opening to the predetermined diameter. The invention also teaches a method of using the dental drill system to form the osteotomy opening, the method comprising the steps of using a starter drill to define at least a portion of the osteotomy opening, using at least one elongate depth drill of a first diameter to drill the osteotomy opening to the predetermined depth, and using at least one elongate width increasing drill of a second greater diameter greater than the first diameter to increase the diameter of the osteotomy opening to the predetermined diameter.

Dental drill system and method of use

An abutment-mount for a dental implant has a longitudinally extending axis with a first end, an opposite second end and a peripheral surface. The abutment-mount is used for delivering the dental implant to a prepared site of a jawbone with an implant drive tool and is also used as a device for securing a dental prosthesis to the dental implant. The abutment-mount includes a screw, or other fastener for securing the abutment-mount to the implant. A surface is provided for attaching the dental prosthesis to the abutment-mount adjacent the first end. A structure is provided for transferring rotational force from the implant drive tool to the implant through the abutment-mount. An implant kit includes an abutment-mount, an implant and an abutment screw.

Abutment-mount system for dental implants

An abutment-mount for a dental implant terminates at one end in an anti-rotation member. The abutment-mount includes a body member having an longitudinal axis and includes a first end and an opposite second end. The first end defines an engagement member that is complementary in shape to the anti-rotation member of the dental implant. A prismatic portion extends from the second end of the body member along the longitudinal axis. The prismatic portion has a plurality of sides, with each side being parallel to the longitudinal axis. The body portion and the prismatic portion define a longitudinal opening passing therethrough that is coaxial with the longitudinal axis.

A ball-topped screw for securing an abutment-mount to a dental implant while taking an impression of the abutment-mount using the indirect transfer method includes an elongated member having a first end and an opposite second end. A portion of the elongated member includes a threaded section for securing the first end of the elongated member and an abutment mount to a dental implant. A spherical member is affixed to the second end, whereby the spherical member provides a gripping shape for a dental impression material that has set around the spherical member while the elongated member secures an abutment mount to a dental implant.

A method of designing a skeletal implant comprises measuring physical characteristics of the bone to be implanted, generating a macro-design of the implant based on the physical characteristics, and determining a micro-design for the implant to ensure that strain in the bone is kept between 100 and 3000 microstrain to promote bone growth and to minimize bone resorption during functional loading. In an alternate embodiment, a dental implant comprises a crest portion having a circular bottom surface, an opposite circular top surface, and a side wall intermediate the bottom surface and the top surface, the top surface being adapted for attaching the dental prosthesis thereto. A circular base portion has a crestal end, an opposite apical end, and a core section intermediate the crestal end and the apical end having an outer surface. A helical thread extends about a portion of the outer surface of the core section that secures the device within existing bone. The bone contacting surface area of the thread increases as the thread nears the crestal end, thereby increasing the surface area over which force is distributed from the implant to the surrounding bone so as to minimize resorption of the existing bone and promote growth of new bone tissue adjacent the device. In an alternative embodiment, a dental implant having a crest module, a threaded first section and a second section, comprises a surface disposed on a selected one of the crest module or the second section for distributing to the bone in a non-longitudinal direction a portion of any longitudinally directed force on the implant.

A single dental appliance that both alleviates snoring and protects teeth from bruxism. The appliance (10) has an upper section (12) which is mounted on the upper jaw. Opposing the upper section (12) is a lower section (14) which is mounted on the lower jaw. Both the upper and lower section have an anterior region (16, 18) and two posterior regions (20, 22; 24, 26). A hard outer shell (32, 34) secures in a soft inner liner (28, 30) which conforms with the teeth and cushions the jaw against impact forces. The hard outer shell (32, 34) serves to protect the teeth against grinding. The combination of the liner and the shell distribute forces associated with grinding.

A dental implant for having a longitudinal axis for implanting in bone, has a crest module having a top end, a bottom end and a wall having an outer surface and a threaded section. The threaded section has a crestal end and an apical end, the crestal end abutting the bottom end of the crest module, a helical thread extending along a portion of the first section from a base end outwardly to a distal end. The threaded section also has a length, a major diameter being defined as the diameter of the threaded section measured at the distal end of the thread and a minor diameter being defined as the diameter of the threaded section measured at the base end of the helical thread. The major diameter is constant along the length of the threaded section, whereas a selected thread feature is chosen as a function of a selected biomedical characteristic. The selected thread feature could include the minor diameter, the thread pitch or the thread geometry. The selected biomedical characteristic is one of the location in the bone in which the implant is placed, the elastic modulus of the bone and the desired biomechanical response of the bone.
