Anatomical restoration dental implant system with reinforced healing cap and abutment

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

• a. a first part further comprising,
• (i) a proximal stem having proximal and distal end portions, the proximal portion of the proximal stem having threads which are threadable within the hollow of the implantable fixture;
• (ii) a divergent segment, the smaller end of the segment being attached to the distal end of the proximal stem, with the axis of the segment being in alignment with the axis of the proximal stem;
• (iii) a distal stem having proximal and distal ends and extending from the larger end of the divergent segment, the axis of the distal stem aligned with the axis of the divergent segment, the distal stem having a threaded surface;
• and
• b. a second part further comprising,
• (i) a cylindrical segment having proximal and distal ends, the cylindrical segment further including a hollow extending from an opening in the proximal end of the segment towards the distal end of the segment, the hollow having threads along at least a portion of its length such that the distal stem of the first part is threadable within the hollow;
• and
• (ii) a screwhead 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 screwhead 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 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 screw 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 removing the cover screw, replacing the screw with a two part reinforced healing cap which includes a removable driven part and a frusto-conical part, the frusto-conical part having a stem threadable with a hollow on the removable driven part, the reinforced healing cap providing a predetermined contour to the gingival tissue adjacent the distal end of the fixture after the jaw bone has grown about the proximal portion of the fixture, thereby causing the gingival tissue to re-heal in a contour reverse to that of the frusto-conical portion of the reinforced healing cap provided;
• d. removing the driven part of the reinforced healing cap and replacing it with reinforced abutment means having a hollow threadably engagable with the stem of the frusto-conical part of the reinforced healing cap, the reinforced abutment means used for supporting a tooth analogue with the implanted fixture;
• and
• e. releasibly attaching a tooth analogue to the reinforced abutment means.

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

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