Facemask therapy with rigid anchorage in a patient with maxillary hypoplasia and severe oligodontia.

In this report, we describe the treatment of a 10-year-old girl with a Class III skeletal relationship with maxillary hypoplasia and severe oligodontia. The maxillary arch was in a complete crossbite relationship with the mandibular arch. The treatment plan called for displacing the maxillary complex anteriorly with a facemask. Because of the lack of available teeth, a rigid anchorage implant was used in combination with the remaining teeth to provide anchorage. A titanium lag screw was placed in the maxillary alveolus. Three weeks later, 800 g of orthodontic force was applied. A significant anterior displacement of the nasomaxillary complex was achieved with the facemask. At the end of treatment, a temporary removable partial denture was placed.

Cephalometric evaluation of open bite treatment with NiTi arch wires and anterior elastics

The aim of this study was to evaluate cephalometrically the effects of open bite treatment with NiTi arch wires and anterior elastics. The study group comprised of 17 patients who displayed a high angle skeletal pattern, along with an anterior open bite. After initial leveling, 0.016 x 0.022 inch upper accentuated-curve and lower reverse-curve arch wires were placed, with anterior elastics applied in the canine regions. Cephalometric assessment was carried out on lateral head films taken at the beginning of treatment and on average 2.8 months after open bite closure was obtained. The results of this study indicated that open bite closure had been achieved mainly by extrusion of the lower incisors and uprighting of the upper incisors. The functional occlusal plane was leveled by extrusion of lower premolars and uprighting of lower molars. Lateral cephalograms obtained from 10 patients who had been available after 1 year postretention were used to evaluate relapse changes. During the follow-up period, position of the upper and lower incisors and the inclination of the occlusal plane were maintained. However, extrusion of upper and lower molar teeth resulted in a reduction in overbite.

Lower Incisor Retraction with a Modified Corticotomy

This case report demonstrates the orthodontic treatment facilitated with a new conservative corticotomy technique to shorten the treatment time during lower incisor retraction. The patient was a 22-year-old woman with protrusive profile, severe anterior crowding, an anterior crossbite, and Class III dental relationship. Orthodontic treatment consisted of the extraction of four first premolars with maximum anchorage. A modified corticotomy technique, in which the lingual vertical and subapical horizontal cuts were eliminated, was combined with orthodontic therapy for the retraction of the lower anterior teeth. Corticotomy-facilitated orthodontics dramatically reduced the treatment time without any adverse effects on the periodontium and the vitality of the teeth. The main advantages of this modified corticotomy technique were the elimination of the lingual cuts and flap, the reduction of surgery time, and minimum discomfort to the patient. At the end of active orthodontic therapy, balanced occlusion and facial esthetics were achieved.

Effects of nasoalveolar molding therapy on nasal and alveolar morphology in unilateral cleft lip and palate.

Objective: The objective of this study was to evaluate the effects of presurgical nasoalveolar molding (PNAM) therapy on nasal and alveolar tissues in patients with unilateral cleft lip and palate. Patients and Methods: Twenty-two patients with a mean age of 23 days, having complete unilateral cleft lip and palate, were included in this prospective study. After the impressions were taken of the palatal and nasolabial regions separately, the maxillary and nasal plaster models were scanned for linear, angular, and area measurements before and after PNAM therapy. The distances between the identified landmarks were measured in the maxillary casts, and the distance and area measurements were performed for the nasal casts with the specified software called Image J developed by the National Institutes of Health. All subjects have undergone PNAM therapy for 6 months. The nasal and maxillary casts are scanned, and the images were evaluated using the software Image J. The alveolar segments should be approximated, and the cleft width and alar base of the affected side after PNAM should be reduced, and the nostril area of the cleft side should be increased. The columella deviation should be decreased. Results: The decrease of the cleft width, arch length, and alar base width on the cleft side and the deviation of the columella were significant, in addition to the significant increase of the arch circumference and nostril area on the affected side (P < 0.001). Conclusions: Presurgical nasoalveolar molding therapy is a significantly helpful treatment for patients with unilateral cleft lip and palate. The reduction in the alveolar cleft region and the nasal reshaping are favorable.

Repeated mandibular lengthening in Treacher Collins syndrome: a case report

A patient with mandibular hypoplasia associated with Treacher Collins syndrome was treated by bilateral distraction osteogenesis. Since less than optimal length was provided by the first distraction, a second corticotomy was performed in the newly formed bone 6 months after the first distraction. Thus bone gained by distraction osteogenesis was subjected to distraction once again. New bone formation occurred after the second lengthening. This case illustrated that distraction osteogenesis may be applied to the mandible at the site of previous distraction.

Midface distraction using spring scale attached to rigid external device.

Distraction osteogenesis has become an al-ternative technique for treatment of craniofa-cial dysplasias. The success of the halo distrac-tion device in the treatment of severe maxillaryhypoplasia associated with cleft palate patientshas led to the application of this device to treatmany more complex craniofacial anomalies.

Facial asymmetry case with multiple missing teeth treated by molar autotransplantation and orthognathic surgery.

Autotransplantation is an alternative treatment in cases of missing teeth. Autotransplantation of teeth can lead to significantly shorter treatment time and an improved treatment result in certain cases of tooth loss, wherever a suitable tooth is available and the anatomic circumstances permit it. The presented case report, treated successfully with molar autotransplantation and orthognathic surgery, had a number of missing teeth and facial asymmetry.

Repositioning of premaxilla in bilateral cleft lip and palate using a "J-hook headgear".

The purpose of this clinical approach is to present the successful treatment of the severely protruded and extruded premaxilla with high-pull J-hook headgear. Two patients with bilateral cleft lip and palate deformity and a protruding and extruding premaxilla causing a deep bite were treated with high-pull J-hook headgear and fixed orthodontic appliances. The lateral cephalometric measurements before and after orthodontic treatment were evaluated with Ricketts analysis. The premaxillae of the two patients were repositioned, correcting the deep overbite and overjet and a well-functioning occlusion was attained. The repositioning of an inferiorly positioned and protruded premaxilla with J-hook headgear is an alternative treatment approach compared to other treatment modalities.
