Patent ID: 8632336

Claim:
A dental implant system comprising a tooth implant, an abutment, a snap-on cap and a transfer part, wherein the tooth implant includes: an apical end, which is rounded; an opposite cervical end; an inwardly oriented chamfer at the cervical end; a conical screw portion located between the apical and cervical ends, the conical screw portion having a progressive multiple thread, and a micro-thread portion adjoining the conical screw portion and having a multiple micro-thread, wherein the conical screw portion and the micro-thread portion extend between the apical end and the cervical end, the conical screw portion begins at the apical end and extends to the micro-thread portion, and the micro-thread portion begins at the conical screw portion and extends to the cervical end; a hexagon socket at the inwardly oriented chamfer spaced from the cervical end, wherein the hexagon socket is tapered to define a conicity, which is in the range from 0.5° to 7°, wherein the abutment comprises a connecting portion at a first end of the abutment that fits into the hexagon socket of the tooth implant and a post at an opposite end of the abutment with a groove located in the post, wherein the transfer part includes a connecting portion which is a hexagonal element and is configured to be plugged into the hexagon socket of the tooth implant when in absence of the abutment, wherein the snap-on cap is a multifunctional snap-on cap having a cross-section with a circular outer surface, the multifunctional snap-on cap having, at its apical end, a bore, which includes an internal neck, which is configured to be snapped into said groove in the post of the abutment, the bore having a first internal surface, which is round and tapered, and a second internal surface, which is flat, the second internal surface of the bore extending along at least a portion of the length of the first internal surface of the bore, and wherein, when the internal neck is snapped into the groove, the first internal surface of the bore is opposed to a first outer surface of the post and the second internal surface of the bore is opposed to a second outer surface of the post, said first outer surface being round and said second outer surface being flat, and wherein the snap-on cap is configured for engaging the abutment and the transfer part is configured for engaging the implant in the absence of the abutment.
