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

Abstract

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.

Dentinogenesis imperfecta: case report with nanoceramic resin crowns restorative treatment

“…Creating crowns using CAD/CAM offers significant advantages over conventional techniques, including faster clinical practice, an improved experience for the patient, and the quality of the restorations. On the other hand, the main limitations are the cost of material, the cost of equipment and the additional costs that may be incurred [20].…”

“…When the preparation and clinical success depend on mechanical friction, digital impressions are an appropriate option. In this case, however, the objective was to prepare the insertion pathways, and this was successfully achieved with the alginate impressions [20].…”

“…As alternative materials for treatment, hybrid resin blocks where resin composite is combined with ceramic particles can be considered. They are characterized by their precision, strength, flexibility and guarantee a long-lasting brightness after restoration [20].…”

A novel DSPP frameshift mutation causing dentin dysplasia type 2 and disease management strategies

“…When the disease progresses to a more severe stage, the retention and bond strength of restorations are affected by pathological abrasion and poor biochemical properties of dental tissues, which limit restorative treatment options. In this situation, glass ionomer cement is available to ensure reliable fixation of the crown restoration (Sarapultseva et al, 2020). If all teeth suffer severe attrition, a complete overlay denture is the best long‐term treatment option to restore occlusal vertical dimensions (Alrashdi et al, 2020; American Academy of Pediatric Dentistry, 2017).…”
