A root-analog dental implant (also known as truly anatomic dental implant) is a medical device to replace one or more roots of a single tooth immediately after extraction. In contrast to common 'off the shelf' titanium screw type implants, these implants are custom-made to match exactly the bony situation of the specific patient.

As the root analog dental implant matches the tooth socket (dental alveolus) it can only be placed in conjunction with the tooth extraction. In other words, if the tooth has been already lost and the soft and hard tissue is already healed a RAI cannot be placed any more.

The basic principle of endosseous implants is a biological process described as osseointegration, in which materials such as titanium or ceramic form an intimate bond to bone. There are no particular differences between the osseointegration of a root analog implant and a conventional screw type implant.

The scope of anatomic dental implants is to fit as perfectly as possible into the bony walls of a tooth socket. By adapting the implant to the patient instead of adapting the patient to a rotationally symmetric screw type implant, any surgery on hard or soft tissue, by drilling healthy bone and filling gaps with cadaver/artificial bone, is absolutely unnecessary.
