“…Bailey et al have reported an 80% chance of less than 2 mm relapse with <8 mm maxillary advancements, 32 and while the magnitude of advancement in our case was 9 mm, we believe it was within the acceptable range, especially with rigid fixation. 33 A drawback of our outcome was the excessive retroclination of the mandibular incisors at the end of treatment, partially due to the extraction of the mandibular premolars, and partially due to the autorotation of the mandible which exacerbated the cephalometric values. Additionally, we were unable to achieve coincident midlines, although the maxillary midline was centered with the face and canine relationships were acceptable, and thus it was deemed to be an acceptable compromise.…”

Cleft lip and Palate (CLP) is the most common craniofacial condition. Management of patients with clefts often requires multi-disciplinary rehabilitation of the orofacial structures. This case report demonstrates the multi-disciplinary management of an adult with a cleft lip and palate, highlighting the benefits of 3-Dimensional (3D) diagnosis, treatment planning and clinical execution of the plan. The patient presented with a severe maxillary deficiency, mandibular asymmetry, and congenitally missing maxillary right central and lateral incisors. This case report demonstrates an alternative approach for the management of cases with ipsilateral missing central and lateral incisors. The maxillary right canine substituted the congenitally missing maxillary right central incisor, while the maxillary right first premolar substituted the congenitally missing right lateral incisor, eliminating the need for prosthetic replacements. Total treatment time was 19 months, and the burden of care for the patient was minimized. An acceptable occlusion was achieved, and the patient’s esthetics improved significantly at the end of treatment. More importantly, the patient reported a marked improvement in his quality of life.

“…The larger contact surface and cross-sectional areas, plus the number of fixation screws, may also explain the higher resistance to vertical and horizontal loading 7. In 2016, Ragaey et al showed that prebent plates in combination with L plates are a more stable method of fixation for maxillary advancements in skeletal Class III patients 8…”

“…7 In 2016, Ragaey et al showed that prebent plates in combination with L plates are a more stable method of fixation for maxillary advancements in skeletal Class III patients. 8 A disadvantage of these plates is that they are larger and more rigid which without any modifications might make them more palpable. 5 With this simple modification, these plates can be easily placed.…”

Prebent plates have gained popularity in recent years as a fixation appliance for large maxillary advancements. They are larger than standard plates used for maxillary procedures and appear to give greater stability. Due to their size and configuration, they have the potential to be more palpable than standard plates, possibly causing discomfort following placement. With a simple “box” osteotomy of the maxilla at the site of placement and a minor modification of the plate, the plate is less palpable and better tolerated by the patient.

“…OS results in improved esthetic appearance, neat dentition, and better masticatory function 1–3. Le Fort I osteotomy is the main orthognathic surgical method used to move the maxillary segment in 3 dimensions (D) to obtain a harmonious positional relationship of the maxilla relative to the overall craniofacial bone 4,5. Although Le Fort I osteotomy improves the patient’s facial contour, it may affect the normal anatomy near the surgical field.…”

To investigate morphological changes of the total and inferior part of the maxillary sinus following Le Fort I osteotomy. 21 skeletal class II and 49 skeletal III patients who underwent orthognathic surgery were enrolled in this retrospective study. Cone-beam computed tomography taken before (T1) and 6 to 24 months after (T2) orthognathic surgery were imported into Mimics 20.0 software to analyze morphological changes of the total and inferior part of the maxillary sinus. Volume of the whole maxillary sinus was significantly reduced after surgery (P ≤ 0.008), while the volume of the inferior part of the maxillary sinus was significantly greater than before surgery (P ≤ 0.004). Maxillary sinus floor moved occlusally after Le Fort I osteotomy. Movement in the pitch direction of the posterior maxilla affected the state of the maxillary sinus mucosa after orthognathic surgery. Le Fort I osteotomy exerts a significant impact on the morphology of the total and inferior part of the maxillary sinus.
