Systems, devices, and methods for designing and manufacturing a dental implant for a multi-rooted tooth

A method for extracting and scanning a multi-rooted tooth having a plurality of tooth roots, the method comprising:

• inserting a plurality of indexing pins into the multi-rooted tooth, wherein each indexing pin comprises a distal portion that is inserted into one of the plurality of tooth roots and a proximal portion that protrudes outward from the multi-rooted tooth;
• creating a mold of an exposed portion of the multi-rooted tooth and the plurality of indexing pins;
• partitioning the tooth into two or more pieces, each piece comprising a tooth root and a corresponding indexing pin;
• extracting the two or more pieces;
• assembling the two or more pieces to reconstruct the multi-rooted tooth, wherein said assembling comprises placing the plurality of indexing pins into the mold;
• and
• imaging the reconstructed multi-rooted tooth.

A method for extracting and scanning a multi-rooted tooth having a plurality of tooth roots, the method comprising:

• inserting a plurality of indexing pins into the multi-rooted tooth, wherein each indexing pin comprises a distal portion that is inserted into one of the plurality of tooth roots and a proximal portion that protrudes outward from the multi-rooted tooth;
• imaging the multi-rooted tooth to create an intra-oral image of an exposed portion of the multi-rooted tooth and the plurality of indexing pins;
• partitioning the tooth into two or more pieces, each piece comprising a tooth root and a corresponding indexing pin;
• extracting the two or more pieces;
• imaging each piece to generate 3D images of each piece;
• generating a 3D model of the multi-rooted tooth, wherein said generating comprises digitally stitching the 3D images of the pieces together based on the indexing pins.

A reconstructed assembly of an extracted multi-rooted tooth, the reconstructed assembly comprising:

• a plurality of separated pieces of the multi-rooted tooth, each separated piece comprising a tooth root having a root canal;
• a plurality of indexing pins comprising a distal portion and a proximal portion, each indexing pin inserted into one of the separated pieces such that the distal portion of the indexing pin conforms to a respective root canal of a respective tooth root and a proximal portion of the indexing pin protrudes outward from the multi-rooted tooth;
• and
• a mold, wherein the mold comprises a plurality of cavities for receiving the plurality of indexing pins so as to orient and position each of the plurality of separated pieces in a configuration corresponding to the multi-rooted tooth prior to extraction.
