## Patient's history

Amelogenesis imperfecta (AI) occurrence is 1/700 to 1/14000 individuals worldwide. Enamel defects leads to esthetics and functional imperments for child and teenagers

Through a clinical case of a 12-year-old patient with amelogenesis imperfecta, we will illustrate a therapeutic option.

Medical history: 0

Dental history:
Diagnosis of AI since he's 6 yo
zirconia pediatric crowns on deciduous molars (2018)

Stainless Steel pediatric crowns on 16 and 26 + extraction (asked by the orthodontist) of 74, 75, 84, 85 (2019)

Patient request: "more common and white teeth, no more discomfort while eating".

## Clinical examination

Yellow-brown small teeth with irregular shapes, numerous diastemas and dental rotation.

Anterior open bite occlusion and maxillar transversal defect treated by a quad helix on stainless steel crowns
X-rays show taurodentism on teeth 16 and 26, and a complete dental formula.

**Treatment goal:** Use composite restorations to restore teeth' aspects and enabling the use of orthodontic brackets to regain function and aesthetics of all teeth.

## Treatment plan

* Extraction of 55 and 12

* Wax up of the "ideal teeth" made on the duplicate of the initial models

* Production of composite crowns:

* injection of composites into the transparent silicone trays thermoformed from waxups

* trays positioned on the initial models and photopolymerization

* crowns removed from the initial models and trays.

* Crown lengthening on the mandibular premolar and molar to optimized composite bonding

* Polishing step and implementation of an orthodontic treatment with brackets and nickel titanium arch (NiTi 0,16 and 0,14)

**Conclusion:** The management of patients with AI must allow for the improvement/restoration of aesthetics and functions. Composite restorations allow simple management during adolescence and improve the patient's quality of life
