The protocol utilizes a combination of an outer hard splint layer and an inner soft splint layer, fabricated using virtual construction and 3D printing.

Fabrication involved intraoral scanning to create a digital model, followed by planning of molding vectors and 3D printing of the dual-layered appliances. Each layer was sequentially printed using distinct materials suited to their functional requirements. The treatment duration extended over five months for both cases.</div></div><div><h3>Results</h3><div>In the bilateral CLP case, the PSIO appliance facilitated increased lateral sulci distance, reduced intertuberosity width, medialization of the premaxilla, and approximation of the alveolar segments. This resulted in notable improvements in nasal symmetry and a reduction in the cleft gap prior to surgery. The unilateral CLP case demonstrated significant cleft gap reduction, enhanced nasal symmetry, and increased intercanine width.</div></div><div><h3>Conclusions</h3><div>The proposed dual-layered PSIO technique represents a significant advancement in the presurgical management of infants with CLP by incorporating digitally designed and directly 3D-printed appliances.

Although rapid maxillary expansion (RME) achieves faster skeletal changes, it can lead to adverse effects such as excessive tipping, root resorption, and residual stress, primarily due to the higher force levels applied. In contrast, slow maxillary expansion (SME) facilitates gradual physiological adaptation with a balanced ratio of skeletal-to-dental changes, reduced relapse rates, and a lower incidence of tissue damage. When selecting a maxillary expansion technique, patient-specific factors, including age, growth potential, and cooperation tolerance should be considered. The biocreative clear expander (Clex) is an effective SME device that offers stable and uniform expansion forces across the maxilla while minimizing individual tooth movement, reducing interference with mandibular motion, and enhancing oral hygiene due to its removability.

When force is applied between the anterior lever arm of the APLR and a TAD in the midpalatal area, the anterior teeth are intruded and retracted with torque control. Because the direction of the APLR force and the guide bar are not parallel, intrusive force is generated in the posterior teeth. Due to this total intrusion of the maxillary dentition, the mandible is rotated counterclockwise, improving AOB with severe incisor exposure.
