• (d) a bottom plate;
• comprising a third fitting means configured to coincide with the second fitting means of the housing plate, and a third fixing means configured to coincide with the second fixing means of the housing plate;
• (e) a plurality of dowels, configured to align the base plate, the housing plate and the bottom plate, and
• (f) locking elements, configured to secure and lock the housing plate next to the bottom plate;

A device for chemical treatment and coating of dental implant comprising:

• (a) a sealing shaft, comprising a through-hole;
• the through-hole surrounded by sealing nozzles at each of an end of the hole;
• and
• (b) an implant fixation pin, comprising two thread regions;
• wherein the through-hole is configured to receive a fixation pin and the two thread regions are configured to receive an internal thread of the dental implant, in a manner that when the implant fixation pin passes through the sealing shaft, at least two implant fixation regions are created, in a manner that a coronal region of the dental implant is in contact with the sealing nozzles and access to an inner surface of the implant is impossible.

A manufacturing process of a dental implant comprising the following steps:

• (1) carrying out a machining process of a single body comprising the following steps:
• (a) manufacturing a single body through selective laser fusion of a collet shaft to a preformed implant body;
• (b) attaching the single body to a guide sleeve through an elongated region of the collet shaft;
• (c) fastening the single body to a turning machine by means of the guide sleeve;
• (d) shearing between the preformed implant body and the collet shaft;
• (e) machining of a prosthetic connection of an internal part of the implant body in order to obtain a 3D printed dental implant with the internal part machined;
• and
• (f) finishing the surface of the implant;
• (2) carrying out an anodizing process of the 3D printed dental implant, using a device for anodizing dental implant comprising the following steps:
• (g) assembling of the device for anodizing dental implant with the implant comprising:
• (g1) positioning a base plate in a manner that guide pins are facing upwards;
• (g2) attaching a housing plate in a manner that the guide pins pass through a set of holes of the housing plate;
• (g3) inserting a plurality of dowels by means of a second fitting means from the base plate and the housing plate;
• (g4) placing a sealing structure on the housing plate in a manner around a tip of the guide pins;
• (g5) inserting the dental implant into the device for anodizing dental implant, in a manner that the internal part of the implant fits at the tip of the guide pins, and a coronal end is in contact with the sealing structure;
• (g6) attaching a bottom plate under the device for anodizing dental implant and aligning the bottom plate by fitting a third fitting means with the plurality of dowels;
• (g7) inserting locking elements by means of a second fixing means and a third fixing means;
• and
• (g8) locking the locking elements in a manner to connect the housing plate to the bottom plate;
• (h) removing the base plate along with the guide pins;
• (i) pouring an anodizing solution into a recessed region of the housing plate in a manner that the anodizing solution enters the set of holes and comes into contact with the internal part of the implant;
• (j) removing the locking elements and separating the bottom plate and the housing plate;
• and
• (k) removing the implants;
• (3) carrying out a process for chemical treatment of the 3D printed dental implants, using a device for chemical treatment and dental implant coating comprising the following steps:
• (l) assembling the chemical treatment and coating device comprising:
• (l1) passing a implant fixation pin through a sealing shaft, in a manner that each end of the chemical treatment device has a thread region;
• (l2) threading of an internal thread of the implants in the thread regions, in a manner that the coronal ends of the implants make contact with sealing nozzles, preventing a liquid solution from coming into contact with the internal part of the implants;
• (l4) immersing the chemical treatment and coating device with implant in a treatment solution for a sufficient time;
• (l5) removing the chemical treatment and coating device from the treatment solution;
• (l6) connecting and immersing the chemical treatment and coating device in a solution containing carbon nanostructures;
• (l6) applying an electric current for a time determined according to the number of implants and the type of coating desired;
• and
• (l7) removing the implants.
