CASE REPORT
Surgical Luxation and Orthodontic Traction of an Ankylosed Upper First Molar
Volume 50 : Number 5 : Page 0 : May 2016
Dental ankylosis is a cellular change in the periodontal ligament that results in continuity or fusion between the alveolar bone and cementum, making it impossible for a tooth to erupt completely. It is identified clinically by the failure of a tooth to erupt through the oral epithelium, by incomplete eruption, or by a lack of vertical movement compared with the adjacent teeth and the alveolar bone. Although ankylosis is more common in the primary dentition, it may also affect the permanent teeth, typically the molars. Bone defects are often associated, especially when ankylosis occurs during active vertical growth of the maxilla.

An Effective Approach to Correcting Anterior Crossbite in a Class III Patient
Volume 54 : Number 11 : Page 705 : Nov 2020
When early treatment is impossible, permanent teeth can be moved to compensate for a skeletal Class III discrepancy and anterior crossbite. The authors demonstrate the use of a 2 × 4 appliance and acrylic biteplane to correct a late-diagnosed skeletal Class III malocclusion.

Mandibular Molar Protraction with the Forsus Appliance as Anchorage Reinforcement
Volume 56 : Number 12 : Page 725 : Dec 2022
A Forsus fixed functional appliance is used for anchorage during protraction of the lower molars in a young patient with missing lower second premolars. This approach corrects the Class II, division 1 malocclusion while avoiding overretraction of the lower incisors.

Lower Incisor Extraction Treatment with the Invisalign System
Volume 36 : Number 2 : Page 95 : Feb 2002
Single-lower-incisor extraction cases have rarely been published, perhaps because there are few patients who meet the standards for such treatment. The following diagnostic characteristics are usually...

Late-Forming Supernumeraries in the Premolar Regions
Volume 28 : Number 3 : Page 0 : Mar 1994
Ninety to 98% of all supernumerary teeth occur in the maxilla, most commonly in the premaxilla.1-3 Maxillary midline supernumeraries are the most common, followed by maxillary lateral incisors, mandib...

Surgical-Orthodontic Treatment Using the Invisalign System
Volume 42 : Number 4 : Page 237 : Apr 2008
Orthodontic malocclusions involving severe skeletal jaw discrepancies are best managed with a combination of orthodontic and surgical treatment. Historically, the surgery has been performed with fixed...

Treatment of Mandibular Alveolar Prognathism by a Lower Anterior Subapical Osteotomy
Volume 32 : Number 12 : Page 747 : Dec 1998
Mandibular alveolar prognathism is often treated by orthodontic treatment without accompanying surgery, in cases where the malocclusion and protrusive profile are not severe enough to warrant sagittal...

Treatment of a Deeply Impacted Mandibular First Permanent Molar
Volume 43 : Number 1 : Page 59 : Jan 2009
Accidental trauma to permanent teeth in children can result in the cessation of eruption due to ankylosis.1-6 Although this situation almost always occurs in the anterior segments, histological analys...

Late Expression of Class III Malocclusion
Volume 45 : Number 5 : Page 275 : May 2011
Early intervention in a Class III case with some combination of a protraction face mask, Frankel and fixed appliances, and a chin cup generally has a good prognosis,1,2 as long as the patient is follo...

Orthodontic Management of a Transposed Maxillary Canine and Lateral Incisor
Volume 41 : Number 7 : Page 0 : Jul 2007
Canines are most frequently transposed with first premolars, and less often with lateral incisors.1-9 Such transposition, which usually occurs in the maxillary arch,2,4,7 is most commonly unilateral,5...

CASE REPORT
Volume 54 : Number 8 : Page 473 : Aug 2020
This adult patient presented with a recurring cyst that had resulted in a severe asymmetrical occlusal deformity. Treatment involving rapid maxillary expansion, followed by asymmetrical orthodontic mechanics with intermaxillary elastics, achieves a functional occlusion and esthetic result.

CASE REPORT
Volume 58 : Number 6 : Page 367 : Jun 2024
In a patient with a missing lower second premolar, the distal half of an ankylosed second deciduous molar is removed to enable mesial drift of the first permanent molar. The mesial half of the tooth is later extracted to allow further mesialization of the first molar using Class II elastics.

Simplified Surgical-Orthodontic Treatment of a Dentigerous Cyst
Volume 28 : Number 2 : Page 0 : Feb 1994
Large dentigerous cysts in the mixed dentition are generally associated with jaw deformity and dislocation of one or more germs of permanent teeth.1 Surgical treatment of cysts usually consists of com...

Uprighting a Horizontally Impacted Mandibular Second Molar
Volume 39 : Number 3 : Page 143 : Mar 2005
The incidence of impacted second molars has been estimated at as many as three in 1,000 cases. Because the second molars tend to erupt at a mesial angle, mesially rotated impactions are fairly common ...

Targeted Mechanics for Limited Posterior Treatment with Mini-Implant Anchorage
Volume 49 : Number 12 : Page 777 : Dec 2015
The introduction of temporary anchorage devices (TADs) has facilitated orthodontic management of complex dentofacial problems. TADs have also elicited the creativity of orthodontists in designing new appliances and approaches for treating different malocclusions. One such approach involves delivering orthodontic forces directly from mini-implants in the buccal segments without bonding the posterior teeth. Introduced by Chung and colleagues, this "biocreative therapy" obtains skeletal anchorage from sandblasted and acid-etched miniscrews, called C-implants, which are placed interdentally between the first molars and second premolars. The archwire is inserted in the anterior brackets and secured posteriorly in the slots of the C-implants to retract the anterior teeth during space closure. Because the implants are partially osseointegrated, they can resist these torsional forces without failing. Chung and colleagues have indicated that biocreative therapy was especially appropriate for cases of bimaxillary dentoalveolar protrusion and Class II cases with good buccal occlusion. Advantages of their method include three-dimensional control of the active units, a minimal need for patient compliance, and significantly reduced risks of root resorption or white-spot lesions in the posterior segments.
