INTRODUCTION: Combined treatment offers advantages for partially edentulous patients. Conventional implants, used as orthodontic anchorage, enable previous orthodontic movement, which provides appropriate space gain for crown insertion. OBJECTIVE: This case report describes the treatment of a 61-year and 10-month-old patient with negative overjet which made ideal prosthetic rehabilitation impossible, thereby hindering dental and facial esthetics. CASE REPORT: After a diagnostic setup, conventional implants were placed in the upper arch to anchor intrusion and retract anterior teeth. Space gain for lateral incisors was achieved in the lower arch by means of an orthodontic appliance. CONCLUSIONS: Integrated planning combining Orthodontics and Implantology provided successful treatment by means of conventional implant-supported anchorage. The resulting occlusal relationship proved stable after 10 years.

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 present case report describes a conservative and uncommon treatment for class III malocclusion in a woman growing patient with aged eight years and four months. An unconventional treatment modality was used for the treatment of this malocclusion, reverse-pull headgear and distalisation of lower teeth using mandibular cervical headgear in the lower arch. At the end of the treatment (after 33 months), there was correction of the transversal and sagittal occlusal relationship between maxilla and mandible and correct dental intercuspation.

A forward functional shift of the mandible is a significant problem that can cause both functional and aesthetic complications for many patients. This shift usually occurs in growing patients, and it is unusual to see in adult patients. This case report shows an adult patient with a forwarding functional shift that caused both anterior and posterior crossbites with a pseudo class III dental and skeletal relationship. The patient also showed severe upper arch crowding with blocked-out canines and mild crowding in the lower arch. The treatment of this patient involved extraction of the upper right and left first premolars and the lower right first premolar, followed by opening of the bite to relieve the neuromuscular reflex of the forward protrusion of the mandible during centric occlusion and to correct both the anterior and posterior crossbites. Extraction spaces were closed using class III elastics and elastomeric chains. At the end of the treatment, good functional and aesthetic results were obtained after the elimination of the forward functional shift.

Before the advent of skeletal anchorage distalisation of the lower arch was considered cumbersome. Individual lower molar distalisation followed by retraction into the distalised space created is very time-consuming. Therefore, to reduce the treatment duration lower arch distalisation can be attempted by using buccal shelf screws. Here we present a case of Angle’s Class III malocclusion which has been treated effectively with distalisation of lower arch using 2 buccal shelf screws (2x12mm) with elastic chains following lower third molars extraction. We achieved full arch distalisation of 3.5mm bilaterally in a span of 1.5 months into a class I molar and canine relationship with normal overjet and overbite. Total treatment duration was of 17 months. These results were stable. There were no changes in vertical facial dimensions.

ABSTRACT Skeletal class III malocclusion treated with orthognathic surgery usually can achieve a better facial profile and stable occlusion outcome. We describe a 37-year-old patient who sought orthodontic treatment for skeletal class III, but refused recommendations for orthognathic surgery because of personal considerations. After careful analysis of the X-ray images and study models, this patient was subjected to active orthodontic treatment to correct malocclusion using upper and lower arch with improved superelastic NiTi alloy wire (ISW) for efficient leveling of the teeth. In the lower arch, the multibends edgewise archwire (MEAW) technique was used to tip back and intrude the canine and posterior teeth. After the completion of treatment, anterior teeth crossbite was successfully corrected and proper occlusal relationships were reestablished.

Various treatment strategies are adopted to correct a Class II malocclusion depending on the age, the amount of remaining growth and severity of malocclusion. Single arch extraction of the lowers is rarely done in a Class II malocclusion. The following case report describes an alternate treatment approach of an adolescent Class II patient treated with a combination of headgear, fixed functional appliance (forsus), and single arch extraction only in the lower arch. The case was finished in a Class III molar and a Class I canine relationship. The results were stable in 3 years follow-up.

This study aims at reporting the clinical case of a patient with Class III skeletal malocclusion with severe maxillary deficiency, producing a reduced midface associated with severe mandibular prognathism. The pre-surgical orthodontic preparation was composed mainly by dentoalveolar expansion and repositioning of the incisors in the lower arch. Then, a combined maxillary and mandibular orthognathic surgery was performed. The treatment objectives were achieved, with significant improvement in facial esthetics and occlusion, followed by post-treatment stability. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements for obtaining the title of Diplomate by BBO.

A variety of treatment options may be implemented on a Class III malocclusion associated with skeletal discrepancy ranging from functional orthopedics at an early age to orthognathic surgery in adults. In the current scenario, many Class III malocclusion patients are referred for orthognathic surgery without even considering the options of an orthodontic camouflage, as orthodontists do not want to burden themselves with the tedious treatment planning and risks involved with treating such cases. This case report describes a 27-year-old female diagnosed with a skeletal Class III malocclusion, severe open bite, and periodontally compromised dentition. Although orthognathic surgery was proposed as the best treatment modality, it was denied by the patient due to financial and psychological constraints. She was treated with mild upper arch expansion using archwires and upper premolar intrusion using temporary anchorage devices (TADs) alongside retraction of lower anterior teeth using TADs and intermaxillary elastics. At the end of 18 months of active treatment, a decent result was achieved with good occlusion and facial esthetics. Post-treatment results showed an improved profile and Class I canine relationships, with optimal overjet and overbite. The anterior open bite was corrected, and the overall facial balance was greatly improved. Extraoral photographs displayed a relaxed lip closure and an esthetic smile meeting the patient’s expectations. Two-year follow-up records demonstrated a stable occlusion and optimal facial esthetics.

Class III malocclusions are considered to be one of the most difficult problems to treat. For us, the complex of these cases is the esthetic of the face and the smile because the treatment of the malocclusions without surgery produces a more retrusive face. We present a case report of an adult male patient with skeletal Class III malocclusion with compression in the maxilla and mandibular asymmetry, who has treated the orthosurgical approach. The result is acceptable in terms of occlusion-function, esthetic of the smile, and facial esthetics.
