title: Modified technique of presurgical infant maxillary orthopedics for complete bilateral cleft lip and palate.
abstract: This article introduces technical modifications to the conventional presurgical infant maxillary orthopedics device for newborns with complete bilateral cleft lip and palate, providing procedural simplicity and efficiency as well as therapeutic efficacy. The modifications incorporate a wax block-out on the stone model prior to device fabrication in a manner that the need for periodic acrylic addition and removal is not required, and thus eliminates the risk of natural maxillary growth restriction during infant maxillary orthopedics treatment. The premaxilla is completely excluded from the acrylic palatal plate and is repositioned primarily by the bilateral labial tape alone. In addition, nasal stent wires are installed on the same day of the palatal plate delivery to establish a tripod-like retention mechanism for the intraoral device to be able to replace the conventional mechanical lock-type retention methods. Applying these modifications, infant maxillary orthopedics treatment objectives for bilateral cleft lip and palate can be successfully achieved within 8 weeks of treatment, and the definitive primary cleft lip repair can be performed within 3-4 months of infant maxillary orthopedics treatment at our Center.
