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.

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.

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.

Familial syndrome of unusual triangular facies associated with cleft palate, malocclusion, midfacial hypoplasia and sensorineural hearing loss in two siblings. Is it a new autosomal recessive syndrome?

We present a previously undescribed syndrome characterized by triangular facial appearance, mid-facial hypoplasia, cleft palate and mild sensorineural hearing loss in two siblings. The parents were unrelated. The patients' stature and intelligence were normal. We suggest that the inheritance is autosomal recessive.

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.

Augmentation mentoplasty using a custom-design wire cage.

Mentoplasty is often a complimentary procedure to rhinoplasty. At least 25% of all rhinoplasty patients may need a chin implant to balance facial features better. Augmentation mentoplasty using alloplastic implants such as silicone, rubber, or other materials provides a simple approach to the treatment of the hypoplastic chin. Although these types of implants are readily available in developed countries, there are parts of the world where they are unavailable or quite expensive. The authors have developed a chin implant made of wire that is available throughout the world and is custom designed to the mentum of the patient after a cephalometric evaluation. This technique has been used in 125 patients along with rhinoplasty over the last 20 years at our institution. In an initial series of 8 patients, the prosthesis became displaced and was removed in 2 patients. Since then, a new radiographic technique has been developed to demonstrate the shape of the mentum before surgery and new bone formation after surgery. By using this special radiographic technique, it was possible to detect four types of mentum before surgery and to construct a custom-design wire cage according to this shape. The prosthesis is constructed by an orthodontist according to the cephalometric measurements and shape of the mentum. By using the buccal approach, a pocket is prepared subperiosteally and a wire cage is inserted. In the last 20 cases, the wire cage was filled with diced cartilage wrapped with Surgicel. The results were esthetically satisfactory in most patients. After the shape of the wire prosthesis was modified to conform to the shape of the underlying bone better, no displacement of the prosthesis has been experienced. In 3 patients, it was necessary to remove the prosthesis when new tissue formation began to fill the prosthesis. These specimens were examined histologically, and the regenerating tissue was found to be connective tissue with a thin layer of bone formation. Most patients could be followed up for only 3 to 12 years. In all patients, the results have been consistent and the procedure has been safe.
