The guide design allows very quick and accurate positioning of the guide with respect to the implant, especially in the case of bone grafts, in the same way as the guide in the surgical guide, but without the need for the surgical guide. The use of the guide design is very intuitive and no other tool is necessary to have the guide, which is very important in surgery. The design and manufacture process is very simple, very fast and very accurate. The only drawback is the limited size of the guides that can be made in the guides design compared to the guides in the surgical guide. I recommend this tool for all users of guided surgery because of its accuracy and simplicity, especially in the case of bone grafts, in the same way as the surgical guide without the need for the surgical guide.
