Surgical strategy for patients with late-diagnosed minor form of cleidocranial dysplasia: Three cases

Abstract

Introduction: Cleidocranial dysplasia is a genetic disease affecting bone growth. Observations: 3 patients, aged 12, 14, and 15 followed an orthodontic and surgical treatment to solve an eruption issue of the permanent teeth. Temporary teeth were extracted and impacted teeth were progressively exposed by multiple surgeries under local anesthesia. Anchorages were placed on the teeth and a traction started, on incisors and molars first, then on premolars, and finally on canines. The treatments lasted for 6 to 8 years. Comments: These patients presented minor form of cleidocranial dysplasia which only affected the teeth. The difficulty of these cases lied in the lateness of their diagnosis and treatment. Adaptations had to be made to simplify treatment plans (shortened dental arch, premolar extractions, etc.).
