Anatomical restoration dental implant system with interlockable angled abutment assembly

An angled abutment assembly attachable to a healing cap mounted on an anatomical restoration dental implant fixture, which is embedded into a patient's jawbone and has an exposed end having a hollow portion with inner screw threads, for supporting a tooth analogue along a direction offset from an axis of the fixture, the angled abutment assembly comprising:

• a. a screw member having a widened head segment, and a shaft segment with a threaded proximal section;
• b. an angled abutment member having a distal divergent portion and a proximal base portion integrally connected together, the divergent portion having a smaller distal end, the base portion having a larger proximal end, the angled abutment member further having an interior bore extending from the proximal end of the base portion to the divergent portion along an axis perpendicular to the proximal end of the base portion and offset from an axis of the divergent portion, the interior bore having a narrow cylindrical distal section and a wide polygonal proximal section;
• and
• c. a bolt member having a hexagonal head segment and an elongated shaft segment with a threaded proximal section, the head segment having a top screw hole, the hexagonal head segment being engaged with said polygonal distal section of said interior bore of said angled abutment member which allows adjustment of the angular orientation of said angled abutment member but acts to prevent any rotation of said angled abutment member after its angular orientation is adjusted;
• d. whereby said bolt member can be used to secure said healing cap to said implant fixture, and said screw member can be used to secure said angled abutment member to said bolt member.

A method for supporting a tooth analogue along a direction offset from an axis of a dental fixture implanted in the gingival tissue and the alveolus of the jawbone in a patient's oral cavity, the method comprising the steps of:

• a. implanting a fixture having proximal and distal end portions, the proximal end portion having means for being embedded in opened gingival tissue and the alveolus of the jaw bone, the distal end portion being accessible from the outer surface of the jaw bone, the fixture being made of a substance permitting healing of the opened gingival tissue and growth of the jaw bone about the fixture, the fixture further including a hollow extending from the distal end portion toward the proximal end portion, the hollow being threaded along at least a portion of its length;
• b. securing a healing cap to said distal end portion of said implanted fixture by using a bolt member, the bolt member having a hexagonal head segment with a top screw hole and an elongated shaft segment with a threaded proximal section which is threaded into said hollow of said fixture;
• c. providing an angled abutment member which has a distal divergent portion and a proximal base portion integrally connected together, the divergent portion having a smaller distal end, the base portion having a larger proximal end, the angled abutment member further having an interior bore extending from the proximal end of the base portion to the divergent portion along an axis perpendicular to the proximal end of the base portion and offset from an axis of the divergent portion, the interior bore having a narrow cylindrical distal section and a wide polygonal proximal section;
• d. placing said angled abutment member on said healing cap and adjusting the angular orientation of said angled abutment member, engaging said head segment of said bolt member with said polygonal proximal section of said interior bore of said angled abutment member to prevent any rotation of said angled abutment member;
• e. securing said angled abutment member to said bolt member by using a screw member which is engageable to said top screw hole of said head segment of said bolt member;
• and
• f. releasibly attaching a tooth analogue to said divergent portion of said angled abutment member such that said tooth analogue is supported along a direction offset from said axis of said fixture.
