Presurgical orthopaedic treatment using hard plates.
Our concept in the treatment of unilateral clefts of lip, alveolus and palate includes early maxillary orthopaedic treatment starting immediately after birth until the end of the first year of life and the surgical closure of the lip at three months and of the soft palate at twelve months. Hard palate and alveolus are closed after three years by secondary osteoplasty in the alveolar region. The appliance is made of hard acrylic resin and is adjusted monthly to allow for growth. It thus encourages passive orthopaedic guidance of maxillary growth. The local compatibility of the plate was excellent and the acceptance by the children created no problems until tooth eruption. Follow-up studies were conducted on twenty children treated in this way until three years of age. After the first year results show a good and harmonious arch alignment without any collapse of the alveolar segments. The cleft narrows and the steepness of the palatal slope flattens. This maxillary development is arrested after suspension of orthopaedic treatment, and a slight collapse of the alveolar segments is observed.
