Step S41, after the horizontal and vertical angles of the support body 12 are completed, there may be an excessively long redundant part after the support bodies 12 are close to each other. At this time, the redundant part can be marked first, and then the redundant part can be marked The cutting tool can be a chainsaw or laser cutting, and the cutting means are not limited here.

In step S51, after the combination of the dental implant load-bearing bracket set 1A is completed, the second end 1132 of each main body 11 may have a redundant part that is too long in order to fit the implant 4 (gingiva) better. At this time, it can be The excess part is marked first, and then the excess part is cut off. The cutting tool can be an electric saw or laser cutting, and the cutting method is not limited here.

In step S61, after the filling is cured, there may be overflowing and cured parts. At the same time, in order to better fit the gums, the cured filling 3 has parts that do not conform to the shape of the gums and may cause discomfort or overflow. For the redundant part, at this time, the redundant part can be marked first, and then the redundant part can be cut off. The cutting tool can be an electric drill or laser cutting, and there is no limit to the cutting means here.

Step S7, after the above steps are completed, the denture body 2 can be further colored and modified, so that the color of the denture body 2 can be closer to the color of the user's mouth, gums, and teeth, making the overall look more natural and beautiful.

It should be noted that the above step S41, step S51 and step S61 are repeatedly adjusted in practice, so step S41, step S51 and step S61 can be replaced or alternately executed according to the actual situation.
