Case report: Rehabilitation of a child with dentinogenesis imperfecta with CAD/CAM approach: Three-year follow-up.

Aim: This study was aimed to describe a minimally invasive and effective method for the aesthetic and functional teeth restoration in dentinogenesis imperfecta (DGI-II) patient.

Methods And Results: A six-year-old boy visited orthodontist and pediatric dentist for the initial consultation with the complaints of aesthetic problems. The treatment plan aimed to correct the vertical dimension of occlusion by prosthetics of the posterior group of teeth with individual milled crowns, followed by restoration of the anterior teeth with crowns made up of the composite material. The digital prosthetic protocol that included the use of an intraoral scanner to take the impressions, minimal teeth preparation, and individual manufacturing via CAD/CAM was followed. Crowns for the first permanent molars were milled from titanium. Crowns from composite material were made on the incisors of the upper and lower jaw, the diastemas between the teeth were closed with the crowns, and the aesthetic disadvantage was corrected.

Conclusion: As a result of the complex treatment, the function and aesthetics were restored, and the prevention of further tooth wear was implemented. This method of rehabilitation is suitable to treat DGI. During 3 years of follow-up, the treatment outcome was considered stable.
