Objective: The long-term treatment results of surgically-assisted facemask therapy were assessed by a comparison of the immediate protraction effects with those seen at five years review.
Materials And Methods: Nine patients treated with a corticotomy-assisted maxillary protraction protocol were recalled five years following protraction. Cephalometric films taken before treatment (T0), immediately after maxillary protraction (T1) and five years after treatment (T2) were compared.
Results: The short-term results of surgically-assisted facemask therapy showed significant skeletal and soft tissue changes. After five years, the profile and dental relationships were well maintained and a cephalometric analysis revealed a stable vertical increase but only partially maintained soft tissue changes with loss of sagittal advancement. There was significant upper incisor proclination providing dental camouflage.
Conclusion: Patients who are treated with corticotomy-assisted maxillary advancement should be very carefully selected. Assessment criteria include a low mandibular plane angle Class III patients who have severe maxillary retrognathism unable to be treated by conventional orthopaedic correction alone; patients who have almost completed growth and missed the chance of earlier orthopaedic correction, as well as patients who are not willing to accept bimaxillary orthognathic surgery, may be successfully treated.

Introduction: This study evaluated the dentoskeletal effects of miniscrew-anchored maxillary protraction, which included a mandibular anchorage bar and a night facemask in adolescents.
Methods: A total of 20 growing patients with Class III malocclusion and maxillary deficiency were treated with a hybrid hyrax expander with 2 miniscrews in the maxilla and a mandibular anchor bar supported in 2 miniscrews in the anterior region of the mandible. Class III elastics were used from the maxillary first molars to the mandibular anchorage bar, joining the mandibular miniscrews installed between permanent incisors and canines.

Objectives: The purpose of this retrospective study was to compare the dento-skeletal changes observed in growing Class III patients treated with the Face Mask Protocol (FMP) with and without Bite Block (BB).
Materials: Thirty subjects (12 f, 18 m) who underwent FM/BB therapy were compared to a matched group (FM) of 29 patients (15 f, 14 m) treated without BB. All patients were evaluated before treatment (T0), at the end of active treatment (T1), and at a post-pubertal follow-up observation (T2).

Objective: This retrospective study aimed to compare the three-dimensional (3D) outcomes of the novel miniscrew-anchored maxillary protraction (MAMP) therapy and the bone-anchored maxillary protraction (BAMP) therapy.
Methods: The sample comprised growing patients with skeletal Class III malocclusion treated with two skeletal anchored maxillary protraction protocols. The MAMP group comprised 22 patients (9 female, 13 male; 10.

Objective: To evaluate the outcomes of skeletal anchorage-supported maxillary protraction and prostetic restoration in a patient with class III malocclusion and hypodontia.
Methods: Anchorage plates were placed in the apertura piriformis region as skeletal anchorage support. Subsequently, 500 g orthopedic force per side was applied for maxillary protraction.

Introduction: This study aimed to compare the efficiency of maxillary protraction achieved through facemask treatment with either a hybrid-hyrax (HH) or an acrylic cap splint (ACS) appliance when used in conjunction with alternate rapid maxillary expansion and constriction (Alt-RAMEC) or conventional rapid maxillary expansion (RME) protocols.
Methods: This study analyzed a total of 60 patients in 4 groups of 15 patients each and treated with HH-Alt-RAMEC protocol (HH-Alt, aged 10.38 ± 1.
