1/16. cleft lip and palate management with maxillary expansion and space opening for a single tooth implant.

    An adult Class I malocclusion with a unilateral cleft lip and palate is presented. The maxillary transverse deficiency was managed with orthopedic expansion and the missing lateral incisor with space opening, bone grafting, and single tooth implant. The mild maxillary retrognathia and deficient lip support was managed with dental compensation.

2/16. Treatment of a Class I malocclusion with a carious mandibular incisor and no Bolton discrepancy.

    Occasionally orthodontists must plan treatment for a patient with extensive caries or a traumatic injury to one mandibular incisor. If the patient has a Bolton discrepancy, one treatment option could involve extraction of the affected mandibular incisor. However, if the patient does not have a Bolton discrepancy and a mandibular incisor is extracted, the treatment becomes more complicated. This case report will present and discuss the ramifications of extracting one mandibular incisor in a patient without an anterior tooth-size discrepancy. The CDABO Student Case Selection Committee chose this case for publication.

3/16. Rapid orthodontics with alveolar reshaping: two case reports of decrowding.

    Two case reports demonstrate a new orthodontic method that offers short treatment times and the ability to simultaneously reshape and increase the buccolingual thickness of the supporting alveolar bone. A 24-year-old man with a Class I severely crowded malocclusion and an overly constricted maxilla with concomitant posterior crossbites and a 17-year-old female with a Class I moderately to severely crowded malocclusion requested shortened orthodontic treatment times. This new surgery technique included buccal and lingual full-thickness flaps, selective partial decortication of the cortical plates, concomitant bone grafting/augmentation, and primary flap closure. Following the surgery, orthodontic adjustments were made approximately every 2 weeks. From bracketing to debracketing, both cases were completed in approximately 6 months and 2 weeks. Posttreatment evaluation of both patients revealed good results. At approximately 15 months following surgery in one patient, a full-thickness flap was again reflected. Visual examination revealed good maintenance of the height of the alveolar crest and an increased thickness in the buccal bone. The canine and premolars in this area were expanded buccally by more than 3 mm, and yet there had actually been an increase in the buccolingual thickness of the overlying buccal bone. Additionally, a preexisting bony fenestration buccal of the root of the first premolar was covered. Both of these findings lend credence to the incorporation of the bone augmentation procedure into the corticotomy surgery because this made it possible to complete the orthodontic treatment with a more intact periodontium. The rapid expansive tooth movements with no significant apical root resorption may be attributed to the osteoclastic or catabolic phase of the regional acceleratory phenomenon. Instead of bony "block" movement or resorption/apposition, the degree of demineralization/remineralization might be a more accurate explanation of what occurs in the alveolar bone during physiologic tooth movement in these patients.

4/16. Treatment of a Class I crowded malocclusion with an ankylosed maxillary central incisor.

    This article describes a Class I crowded malocclusion with an ankylosed maxillary central incisor that was in infraocclusion and labially displaced. Various treatment alternatives are discussed, and the option of extracting the ankylosed tooth followed by space closure with lateral incisor substitution is developed.

5/16. Treatment of a patient with a crowded Class I malocclusion and a congenitally missing mandibular incisor.

    This case report describes the management of maxillary and mandibular crowding in a patient with facial esthetic concerns and a tooth-size discrepancy due to a missing mandibular central incisor. The treatment included extracting the remaining mandibular central incisor and the 2 maxillary first premolars. The mandibular canines were repositioned to substitute for lateral incisors, and the mandibular premolars were used as canines.

7/16. A mini-implant for orthodontic anchorage in a deep overbite case.

    This article describes the orthodontic treatment of a 19-year-old female patient with anterior crowding. There was a moderate arch length discrepancy in the lower dental arch, a significant deep overbite, and a "gummy smile." We inserted an orthodontic mini-implant as anchorage for the intrusion of the upper incisor segment, followed by alignment of the upper and lower dental arches with an edgewise appliance without tooth extraction. The overbite was corrected from 7.2 mm to 1.7 mm by upper incisor intrusion, and the gummy smile was improved. Good occlusion and facial esthetics were achieved, and these results have been maintained for two years after completion of the active treatment.

8/16. Two- and three-dimensional orthodontic imaging using limited cone beam-computed tomography.

    Considerable progress has been made in diagnostic, medical imaging devices such as computed tomography (CT). However, these devices are not used routinely in dentistry and orthodontics because of high cost, large space requirements and the high amount of radiation involved. A device using computed tomography technology has been developed for dental use called a limited cone beam dental compact-CT (3DX). The aim of this article is to demonstrate the usefulness of 3DX imaging for orthodontic diagnosis and treatment planning. We present three cases: (1) one case shows delayed eruption of the upper left second premolar, (2) the second case shows severe impaction of a maxillary second bicuspid; and (3) the third case shows temporomandibular joint disorder (TMD). In the tooth impaction cases, the CT images provided more precise information than conventional radiographic images such as improved observation of the long axis of the tooth, root condition, and overlap with bone. In the TMD case, clear and detailed temporomandibular joint images were observed and pre- and posttreatment condylar positions were easily compared. We conclude that 3DX images provide useful information for orthodontic diagnosis and treatment planning.

9/16. An American Board of orthodontics case report. Orthodontic treatment of a patient born with a severe right unilateral cleft lip and palate.

    The patient was born with a severe cleft of the right lip, alveolus, and palate. After surgical correction of these defects at a very young age, the patient began a 6-year period of active orthodontic treatment at the Eastman Dental Center. With the cooperation of the patient and his parents, successful results, both dentally and skeletally, have been achieved. The treatment results have been stable during the 3-year period following the initial placement of retention. The postretention records show a molar relationship within normal limits and some return of the original spacing located in the mandibular anterior segment. The bonded "maryland bar" is still in place and the cast single-tooth partial is still being used. At the proper time, a fixed permanent bridge is planned.

10/16. Autotransplantation of cryopreserved tooth in connection with orthodontic treatment.

    In orthodontic treatment of certain cases of tooth loss, aplasia, or ectopia, autotransplantation is sometimes a valid treatment alternative and often provides an improved result, compared to conventional orthodontic treatment, if an appropriate donor tooth is available and the anatomic circumstances permit it. However, in some cases autotransplantation is not immediately possible as a one-step procedure. In such cases cryopreservation provides a clinically useful technique when an extraoral storage period of months or years is needed to orthodontically prepare the recipient region. In the present case a mature upper first left premolar was stored for 18 months. During this period sufficient space was achieved in the contralateral recipient region between the upper left first and second premolars. The thawed graft was autotransplanted to this position. Endodontic treatment was initiated 4 weeks after transplantation. Four years after transplantation, the periodontal healing of the grafted tooth appeared clinically and radiographically normal without any signs of root resorption. The presented case demonstrates the capacity of a cryopreserved tooth to regenerate what seems to be a normal periodontium after transplantation. If these findings are confirmed in further clinical trials, the technique could be a valuable tool in future orthodontic treatment planning.
