Implant system

A method of installing a dental restoration in the oral cavity of a patient comprising the steps of:

• providing a fixture (301;
• 401;
• 501) having an outer surface, wherein at least a section of the outer surface (305;
• 405;
• 505) is adapted for interlocking with bone tissue (312;
• 314;
• 512;
• 514) of the maxilla or mandible, and a rearward end providing a female recess having a rearward opening and a boundary wall,
• providing a superstructure (402) on which the detail restoration is formed or mountable, the superstructure comprising a forward end providing a male projection having a boundary wall, wherein
• said boundary wall of the female recess of the fixture and said boundary wall of the projection of the superstructure each present a predetermined interfacing surface capable of interfacing with each other, each of said interfacing surfaces being presented by a predetermined forward section of the respective boundary wall and having a substantially conical profile with flank surfaces which converge in the forward direction at a substantially common angle,
• implanting the fixture in the maxilla or mandible of the patient in a forward direction in the maxilla or mandible such that at least a forward part of at least a section of the outer surface of the fixture is positioned at a level forward of a predetermined position at which interlocking between the fixture outer surface and bone tissue commences, and said boundary wall of the female recess extends forwardly from said recess opening and beyond said predetermined position, and
• mounting the superstructure on the fixture such that the predetermined interfacing surfaces of the superstructure and the fixture, respectively, interface, each of said interfacing surfaces being disposed forwardly of the predetermined position, and the boundary wall of the projection of the superstructure and the boundary wall of the female recess of the fixture are spaced-apart from each other rearward from where the predetermined forward sections interface.

A fixture (301;

• 401;
• 501) of a dental implant system capable of being implanted in bone tissue (312, 314;
• 512, 514) of the maxilla or mandible by displacement of the fixture in a forward direction in the maxilla or mandible, the fixture comprising:
• a forward end,
• a rearward end providing a female recess having a rearward opening and a boundary wall (330;
• 430;
• 530), and
• an outer surface (305;
• 405;
• 505) which extends between the forward and rearward ends and which forwardly of a predetermined position (307;
• 407;
• 507) on the outer surface is adapted for interlocking with bone tissue of the maxilla or mandible;
• said boundary wall of the female recess extending forwardly from said recess opening and beyond said predetermined position,
• wherein the fixture is further adapted for securably mounting a superstructure thereon, the superstructure comprising:
• a forward end providing a male projection having a boundary wall
• wherein,
• (i) said boundary wall of the female recess of the fixture and said boundary wall of the projection of the superstructure each present a predetermined interfacing surface capable of interfacing with each other, each of said interfacing surfaces being disposed forwardly of the predetermined position, and each of said interfacing surfaces being presented by a predetermined forward section of the respective boundary wall and having a substantially conical profile with flank surfaces which converge in the forward direction at a substantially common angle, and
• (ii) the boundary wall of the projection of the superstructure and the boundary wall of the female recess of the fixture are sized and configured to be spaced-apart from each other rearward from where the predetermined forward sections interface.

A superstructure of a dental implant system capable of being securably mounted on a dental implant system fixture (301;

• 401;
• 501), the fixture capable of being securably implanted in bone tissue (312, 314;
• 512, 514) of the maxilla or mandible by displacement of the fixture in a forward direction in the maxilla or mandible, and the fixture comprising:
• a forward end,
• a rearward end providing a female recess having a rearward opening and a boundary wall (330;
• 430;
• 530), and
• an outer surface (305;
• 405;
• 505) which extends between the forward and rearward ends and which forwardly of a predetermined position (307;
• 407;
• 507) on the outer surface is adapted for interlocking with bone tissue of the maxilla or mandible;
• said boundary wall of the female recess extending forwardly from said recess and beyond said predetermined position,
• the superstructure comprising:
• a forward end providing a male projection having a boundary wall,
• wherein,
• (i) said boundary wall of the female recess of the fixture and said boundary wall of the projection of the superstructure each present a predetermined interfacing surface capable of interfacing with each other, each of said interfacing surfaces being disposed forwardly of the predetermined position, and each of said interfacing surfaces being presented by a predetermined forward section of the respective boundary wall and having a substantially conical profile with flank surfaces which converge in the forward direction at a substantially common angle, and
• (ii) the boundary wall of the projection of the superstructure and the boundary wall of the female recess of the fixture are sized and configured to be spaced-apart from each other rearward from where the predetermined forward sections interface.
