An anatomical restoration dental implant system implantable in the gingival tissue and the alveolus of the jaw bone, comprising:

• a. a dental implant 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 having an exposed end 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 an opening in the distal end portion towards the proximal end portion, the hollow having threads along at least a portion of its length;
• b. means for sealing the hollow of the implant fixture during a period after implantation in which the jaw bone is growing about the proximal portion of the implant fixture;
• c. healing cap means for providing a predetermined oval contour to the gingival tissue adjacent the distal end of the implant fixture, such that the gingival tissue re-heals in an oval contour which conforms to the contour of the healing cap means;
• d. a tooth analogue having a rounded isosceles triangle shaped root;
• e. abutment means for supporting the tooth analogue;
• f. means for securing said tooth analogue to said abutment means;
• g. said healing cap means being an interlockable healing cap assembly, including:
• (i) a bolt member having a widened head segment and an elongated shaft segment, the shaft segment having a proximal end and a distal end, and the head segment integrally connected to the distal end of the shaft segment, the shaft segment further having a proximal section and a distal section, the proximal section having outer screw threads compatible with said inner screw threads of said hollow portion of said implant fixture, and the distal section being smooth,
• (ii) a healing cap member having a divergent body with a smaller proximal end, a larger distal end, and a stepped interior bore extending from the distal end of the healing cap member to the proximal end of the healing cap member, the smaller proximal end being circular shaped, the larger distal end being rounded isosceles triangle shaped, and the interior bore having a wide proximal section, and a narrow distal section, the proximal section of the interior bore being smooth, and the distal section of the interior bore having inner screw threads compatible with said outer screw threads of said proximal section of said shaft segment of said bolt member,
• (iii) said healing cap member and said bolt member being interlockable by threading said proximal section of said shaft segment of said bolt member into said distal section of said interior bore of said healing cap member,
• (iv) said distal section of said shaft segment of said bolt member being longer than said distal section of said interior bore of said healing cap member, such that after said proximal section of said shaft segment of said bolt member is completely threaded through said distal section of said interior bore of said healing cap member from said distal end of said healing cap member, said healing cap member and said bolt member are no longer threadably engaged,
• (v) said shaft segment of said bolt member being longer than said interior bore of said healing cap member, such that after said shaft segment of said bolt member extends through said interior bore of said healing cap member from said distal end of said healing cap member, there is still a substantial portion of said proximal section of said shaft segment of said bolt member which can be threadably engaged with said implant fixture for fastening said healing cap member to said exposed end of said implant fixture;
• (h) said abutment means being a matching abutment member further comprising:
• (i) a proximal bolt segment being identical to said bolt member of said healing cap assembly,
• (ii) a distal frusto-conical shaped head segment having a larger proximal end integrally connected to said proximal bolt segment, and a smaller distal end with means for adapting a driving tool, and
• (iii) said large proximal end of said distal frusto-conical shaped head segment of said abutment member being circular shaped and smaller than said rounded isosceles triangle shaped distal end of said healing cap member, such that when said abutment member is attached to said healing cap member in replacement of said bolt member for supporting said tooth analogue, a rounded isosceles triangle shaped shoulder is created for matching said rounded isosceles triangle shaped root of said tooth analogue.

An interlockable healing cap assembly attachable to 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, the healing cap assembly comprising:

• a. an integral bolt member having a widened head segment and an elongated shaft segment, the shaft segment having a proximal section with screw threads and a smooth distal section;
• b. a healing cap member having a divergent body with a smaller proximal end, a larger distal end, and a stepped interior bore extending from the distal end to the proximal end, the larger distal end having a rounded triangle shape, and the interior bore having a smooth proximal section and a threaded distal section;
• c. said healing cap member and said bolt member being interlockable by threading said proximal section of said shaft segment of said bolt member into said distal section of said interior bore of said healing cap member;
• d. said distal section of said shaft segment of said bolt member being longer than said distal section of said interior bore of said healing cap member, such that after said proximal section of said shaft segment of said bolt member is completely threaded through said distal section of said interior bore of said healing cap member from said distal end of said healing cap member, said healing cap member and said bolt member are no longer threadably engaged;
• and
• e. said shaft segment of said bolt member being longer than said interior bore of said healing cap member, such that after said shaft segment of said bolt member extends through said interior bore of said healing cap member from said distal end of said healing cap member, there is still a substantial portion of said proximal section of said shaft segment of said bolt member which can be threadably engaged with said implant fixture for fastening said healing cap member to said exposed end of said implant fixture.

A method for implanting a tooth analogue with rounded triangle shaped root 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. sealing the hollow of the fixture with a cover means during a period after implantation in which the jaw bone is growing about the proximal portion of the fixture and the opened gingival tissue is healing, thereby preventing the jaw bone from entering the fixture;
• c. reopening the gingival tissue and replacing said cover means with a healing cap assembly which includes a bolt member and a healing cap member having a divergent body with a smaller proximal end, a larger distal end, and an interior bore extending from the distal end to the proximal end, where the larger distal end is rounded triangle shaped;
• d. removing said bolt member and replacing it with a matching abutment member which has a proximal bolt segment identical to said bolt member and a distal frusto-conical shaped head segment having a smaller distal end and a larger proximal end integrally connected to the proximal bolt segment, where the larger proximal end is circular shaped and smaller than said rounded triangle shaped distal end of said healing cap member, such that when the matching abutment member is attached to said healing cap member in replacement of said bolt member for supporting said tooth analogue, a rounded triangle shaped shoulder is created for matching said rounded triangle shaped root of said tooth analogue;
• and
• releasibly attaching said tooth analogue having a rounded triangle shaped root to said matching abutment member such that said rounded triangle shaped root of said tooth analogue matches said rounded triangle shaped shoulder created at the conjunction of said healing cap member and said matching abutment member.
