Non-surgical treatment of vertical excess of the premaxilla in growing bilateral cleft lip and palate patients.

Patients with bilateral complete cleft lip and palate (BCLP) may present a vertical excess of the premaxilla in childhood. This is a severe functional and aesthetic problem, where bone grafting is more challenging. The aim of this study was to describe a simple and reproducible non-surgical orthopaedic treatment for vertical excess of the premaxilla in the deciduous/early mixed dentition phase in BCLP patients. Six growing patients with complete BCLP with a severe vertical excess of the premaxilla were included. An intrusion device associated with a bonded rapid palatal expander was applied to intrude the premaxilla. Radiographic and photographic records obtained before and at the end of the orthodontic intrusion, at short- and long-term follow-up, were available. A flattening of the occlusal plane was achieved in all patients. Normalization of the position of the maxillary incisors and gingival display in relation to the upper lip was obtained, and an improvement in anterior nasal spine position was also observed in all cases. The novel technique described might be of assistance in treating BCLP children with vertical excess of the premaxilla during the deciduous/early mixed dentition phase. This simplified, easily reproducible method may allow the burden of care of this rare but complex problem affecting BCLP patients to be reduced significantly.
