Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Miniplate Group (MP)
An incomplete Le Fort 1 osteotomy was performed in all patients to free the maxilla. Miniplates were placed vertically between the mandibular canine and first premolar in all groups, and horizontally under the osteotomy line in the maxillary molar region. Class III elastics were applied 5 days after the surgery. Treatment was continued until a positive overjet was achieved. Cephalometric radiographs were taken at the beginning of treatment (T0) and at the end of the protraction period (T1).

Acrylic Splint Group (AS)
An acrylic splint containing hooks in the upper molar region was prepared and cemented to the upper dentition. An incomplete Le Fort 1 osteotomy was performed in all patients to free the maxilla. Miniplates were placed vertically between the mandibular canine and first premolar in all groups, and horizontally under the osteotomy line in the maxillary molar region in miniplate group (MP). Class III elastics were applied 5 days after the surgery. Treatment was continued until a positive overjet was achieved. Cephalometric radiographs were taken at the beginning of treatment (T0) and at the end of the protraction period (T1).

Palatal Miniscrew Supported Acrylic Splint Group (MS)
An acrylic splint containing hooks in the upper molar region was prepared and cemented to the upper dentition. Two miniscrews were used in the palatal region for additional anchorage. An incomplete Le Fort 1 osteotomy was performed in all patients to free the maxilla. Miniplates were placed vertically between the mandibular canine and first premolar in all groups, and horizontally under the osteotomy line in the maxillary molar region in miniplate group (MP). Class III elastics were applied 5 days after the surgery. Treatment was continued until a positive overjet was achieved. Cephalometric radiographs were taken at the beginning of treatment (T0) and at the end of the protraction period (T1).
