Method for manufacturing a splint or surgical guide for the implantation of at least one dental implant

A method for manufacturing a splint/surgical guide (4) for implantation of at least one dental implant (1), comprising the following steps:

• obtaining, by means of a scanning system and a computed tomography system, at least one three-dimensional image of a patient's oral cavity, to generate a digital oral model,
• determining features of the dental implant (1) to be implanted, including type, height and diameter of the dental implant (1), as well as location of a head of the at least said dental implant in the digital oral model,
• generating, based on the type and location of the at least one dental implant (1), a virtual surgical plan, which includes, at least:
• creating a digital design of a surgical guide or splint (4) comprising at least one hole with a guide and stop ring (3), the stop ring located at a first distance from the location of the head (11) of the implant (1) in the digital oral model,
• choosing at least one milling tool (40) to be inserted into the hole of the splint (4), with a diameter sized based on the diameter of the implant (1), an inactive length (42) with a washer or protrusion (43) configured to come in contact with the guide and stop ring (3), and a machining length (41) ending at a free end (44), with the machining length (41) being greater than the height of the implant (1) and a distance between the washer or protrusion (43) and the free end (44) of the machining length (41) being equal to a sum of the first distance and the height of the implant, such that increasing or decreasing said first distance, varying a height of the splint (4) depending on the location of the head (11) of the implant (1), wherein the same at least one milling tool (40) can be used to machine different implant channels with the same diameter and different heights,
• determining the milling sequence by using the at least said milling tool (40) for machining the implant insertion channel in a jaw of the digital oral model, and
• manufacturing the splint or surgical guide (4) based on the digital design;
• and
• wherein the method comprises a further step for generating the virtual surgical plan, after determining the milling sequence, is determining a dental implant carrier with a specific diameter for insertion along with the implant into the hole of the splint for subsequent fastening in the implant insertion channel, said carrier being joined to the implant through a joining end having said end a diameter equal or less than that of the head of the implant, said carrier having a greater length than the first distance between the ring of the splint and the head of the implant.
