Anatomical restoration dental implant system with improved healing cap and abutment

A two part healing cap for use with an implantable fixture having an open end and a threaded hollow, the healing cap comprising:

• a. a first part further comprising,
• (i) a stem having proximal and distal end portions, the proximal end portion being threadable within the hollow of the implantable fixture thereby sealing the fixture;
• (ii) a divergent segment having frusto-conical shape, the smaller end of the segment being attached to distal end of the stem, with the axis of the segment being in alignment with the axis of the stem;
• (iii) the divergent segment further including a hollow extending from an opening in the larger end of the segment toward the smaller end of the segment, the hollow having threads along at least a portion of its length,
• b. a second part further comprising,
• (i) a cylindrical segment having proximal and distal ends, the proximal end having a stem extending transversely to the proximal end, the axis of the stem aligned with the axis of the cylindrical segment, the stem having a threaded surface which is threadable within the hollow of the divergent segment, with the axis of the cylindrical segment being in alignment with the axis of the divergent segment, and
• (ii) a screw head segment having a proximal end and a driven end, the driven end cooperable with a driving tool, the proximal end being attached to the distal end of the cylindrical segment, with the axis of the screw head segment being in alignment with the axis of the cylindrical segment.

A method for implanting a tooth in the gingival tissue and the alveolus of the jawbone comprising:

• a. implanting a fixture having proximal and distal end the proximal end portion having means for being embedd 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 perm . healing of the opened gingival tissue and growth of bone about the fixture, the fixture further including hollow extending from the distal end portion toward the proximal end portion, the hollow being threaded along a portion of its length;
• b. sealing the hollow portion of the fixture with a cover screw a period after implantation in which the jaw bone is about the proximal portion of the fixture and the opened gingival tissue is healing, thereby preventing the jaw bone entering the fixture;
• c. reopening the gingival tissue and removing the cover screw, replacing the screw with a two part healing cap which includes a driven part and a frusto-conical part which provides a predetermined contour to the gingival tissue adjacent distal end of the fixture after the jaw bone has grown about the proximal portion of the fixture, thereby causing gingival tissue to re-heal in a contour reverse to that the frusto-conical portion of the healing cap provided;
• d. removing the driven part of the healing cap and replacing it with abutment means engagable with the frusto-conical portion of the healing cap, the abutment means used for supporting a tooth analogue with the implanted fixture;
• and
• e. releasibly attaching a tooth analogue to the abutment means.

A two part abutment device for use with an implantable fixture having an open end and a threaded hollow, the abutment device comprising:

• a. a first part further comprising,
• (i) a stem having proximal and distal end portions, the proximal end portion being threadable within the hollow of the implantable fixture thereby sealing the fixture;
• (ii) a divergent segment having frusto-conical shape, the smaller end of the segment being attached to the distal end of the stem, with the axis of the segment being in alignment with the axis of the stem;
• (iii) the divergent segment further including a hollow extending from an opening in the larger end of the segment toward the smaller end of the segment, the hollow having threads along at least a portion of its length;
• and
• b. a second part being a head segment having a frusto-conical shape, the larger end of the head segment attached to a stem extending transversely to the larger end, the axis of the stem aligned with the axis of the head segment, the stem having a threaded surface which is threadable within the hollow of the divergent segment, with the axis of the head segment being aligned with the axis of the divergent segment.
