Dental Implantation in Congenital Absence of Lateral Incisors and Minimal Distance between the Roots of Adjacent Teeth

A patient addressed the doctors with the implantation of lateral incisors in the upper jaw. He had previously undergone orthodontic treatment with a bracket system, since the distance between the central incisors and canine teeth was only 2 mm; and the minimum diameter of the implant was 3.5 mm. With the help of a bracket system, it was possible to expand the space between the roots of the teeth to 4-4.5 mm.

The difficulty in this case lies in that in such conditions, it is very difficult to drill a hole in the jawbone for implant placement without damaging the roots of the adjacent teeth. The patient had previously consulted about dental implantation in another medical center, where they made a surgical template with implant guides (an individually designed mouthpiece with holes for implant insertion).

We implanted two missing lateral incisors without using 3D navigation and surgical templates. The distance between the implant and the roots of the patient’s teeth was only 0.5 mm, but the operation was successful. The roots of the teeth were not affected, which was later confirmed by X-rays.

Three hours later, after the implants were placed, we fixed temporary crowns on them, and the patient left the den medical center with a new, beautiful smile. In a few months, temporary crowns were replaced with permanent ones.
