Introduction: This case report describes an orthodontic interception of a mixed dentition reverse incisor bite in a 12-year-old boy at the time of consultation. Case Report: After a careful clinical examination supported by routine radiological examinations, a skeletal class III diagnosis was made and an orthodontic interception was decided to restore the inverted incisor joint and the various orofacial functions disrupted by the malocclusion. After twenty months of interceptive treatment consisting of a joint jump and class III intermaxillary traction, we found satisfactory overhang and coverage allowing us to monitor the placement of the definitive canines with an improvement in the skin profile and smile. Conclusion: This simple gesture which made it possible to put the mandible back in a position restoring normal incisal coverage contributes to good orofacial muscle maturation closely linked to the various occlusal functions restored.

Background/Aim. In malocclusion of skeletal class III, mandible is located in front of maxilla in sagital plain, which is manifested by a lower value of the sagital inter-jaw angle than in skeletal class I, where the jaw sagital relation is normal. Apart from the deformities on mandible and/or maxilla, in skeletal class III deformities are also frequent on the cranial base. The aim of this research was to find the differences in the parameter values on the cranial base among the children with skeletal class III and the children with skeletal class I in the period of mixed dentition. Methods. After clinical examination and orthopan-tomography, profile radiography of the head was analyzed in 60 examinees, aged from 6?12 years. The examinees were divided into two groups: group 1 - the children with skeletal class III; group 2 - the children with skeletal class I. Both linear and angular parameters on the cranial base were measured, as well as the angles of maxillary and mandible prognatism and the angle of sagital inter-jaw relation. The level of difference in the parameter values between the groups was estimated and the degree of correlation of the main angle of the cranial base with the angles of sagital position of the jaws in each of the two groups was established. Results. A significant difference between the groups was found only in the average values of the angles of maxillary prognatism and sagital interjaw relation. In the group 1, the main angle of the cranial base was in a significant correlation with the angles of sagital positions of the jaws, while in the group 2, such significance was not found. Conclusion. There were no significant differences in the parameter values on the cranial base between the groups. There was a significant correlation of the main angle of the cranial base with the angles of sagital position of the jaws in the group 1 only. .

Molar Extraction

A skeletal Class III malocclusion with open bite tendency is considered very difficult to treat orthodontically without surgery. This case report describes the lingual orthodontic treatment of an adult skeletal Class III patient with mandibular deviation to the left side, lateral open bite, unilateral posterior crossbite, zero overbite and negative overjet. The lower incisors were already retroclined to compensate with the skeletal discrepancy. The patient was treated by asymmetric molar extraction in the mandibular arch to retract the lower incisors and correct the dental midline, with the help of intermaxillary elastics. Lingual appliance was used with over-torqued lower anterior teeth’s brackets to control the torque of mandibular incisors. After a 30-month treatment, satisfactory smile and facial esthetics and good occlusion was achieved. A 12-month follow-up confirmed that the outcome was stable. Asymmetric molar extraction could be a viable option to retract mandibular incisors in Class III malocclusion with lower dental midline deviation.

The Alt-RAMEC protocol was introduced by Liou in the year 2005. It allows for sutural mobilisation by opening and closing the RME screw for 7-9 weeks. Maxillary protraction after the use of Alt-Ramec (alternate rapid maxillary expansion and contraction) protocol is an efficient method for early treatment of skeletal Class III malocclusion. This case report shows the results of using a hyrax bonded maxillary expander with the Alt-RAMEC protocol to treat a maxillary hypoplasia Class III malocclusion. A 12-year-old patient with skeletal class III malocclusion with anterior as well as the unilateral posterior crossbite was treated using this protocol. CBCT scans were taken before and after expansion. These CBCT scans were used for assessing and analysing the skeletal changes that have occurred after using the AltRamec protocol. The objective of this case report is to assess skeletal changes after using the Alt-RAMEC protocol.

VG, 25-year-old male, presented with c/c of forwardly placed lower jaw and history of unsatisfactory previous orthodontic treatment. Extraorally, the patient had asymmetrical face and concave profile, competent lips, positive lip step, and chin deviated toward left side by 2 mm. Intraorally, the patient had Angle’s class III type 3 malocclusion with an overjet of (–1) mm, overbite of 0%, and cross-bite wrt 12, 21. The patient was skeletal class III due to macrognathic and prognathic mandible with hypodivergent growth pattern, and proclined upper and retroclined lower incisors. The patient was managed orthosurgically with bimaxillary surgery (maxillary advancement 3 mm + mandibular setback 7 mm) after presurgical decompensation. The case report discusses in detail the diagnosis and comprehensive management of the skeletal class III case.

Abstract Deliberate hypotension is an important technique for use in select anesthetics for procedures such as orthognathic surgery, specifically LeFort I maxillary osteotomy. We present a case report of an anesthetic involving deliberate hypotension for a 17-year-old female patient who presented for a LeFort I osteotomy, bilateral sagittal split of the mandible, and a genioplasty in order to correct a skeletal class III malocclusion. After reaching a steady-state general anesthetic, deliberate hypotension was induced solely with a bolus and subsequent continuous infusion of the ultrashort acting calcium channel blocker, clevidipine. The preoperative, intraoperative, and postoperative course and anesthetic management are discussed.
