1/123. Nonsurgical correction of a class II malocclusion with a vertical growth tendency.malocclusion, with a superimposed vertical growth tendency, is often difficult to treat without a combined surgical orthodontic approach. Certain situations, however, may preclude surgery as a treatment option. The following case report demonstrates the use of orthodontic mechanotherapy alone in successfully treating a patient that exhibited a Class II Division I malocclusion with a high mandibular plane angle and vertical growth tendency.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
2/123. Class II malocclusion correction: an American board of orthodontics case.A Class II open bite malocclusion with a narrowed maxilla, an increased lower anterior facial height, and a tooth size discrepancy are presented. The malocclusion was treated nonextraction in 2 phases. The mixed dentition phase of treatment was maxillary molar uprighting followed by a bonded rapid palatal expander. The vertical dimension was managed with a vertical pull chincup. The full appliance phase included buildups of the maxillary lateral incisors and mechanics to control lower incisor position.- - - - - - - - - - ranking = 80.363625361959keywords = open bite, bite, open (Clic here for more details about this article) |
3/123. Idiopathic condylar resorption: diagnosis, treatment protocol, and outcomes.Idiopathic condylar resorption is a poorly understood progressive disease that affects the TMJ and that can result in malocclusion, facial disfigurement, TMJ dysfunction, and pain. This article presents the diagnostic criteria for idiopathic condylar resorption and a new treatment protocol for management of this pathologic condition. Idiopathic condylar resorption most often occurs in teenage girls but can occur at any age, although rarely over the age of 40 years. These patients have a common facial morphology including: (1) high occlusal and mandibular plane angles, (2) progressively retruding mandible, and (3) Class II occlusion with or without open bite. Imaging usually demonstrates small resorbing condyles and TMJ articular disk dislocations. A specific treatment protocol has been developed to treat this condition that includes: (1) removal of hyperplastic synovial and bilaminar tissue; (2) disk repositioning and ligament repair; and (3) indicated orthognathic surgery to correct the functional and esthetic facial deformity. patients with this condition respond well to the treatment protocol presented herein with elimination of the disease process. Two cases are presented to demonstrate this treatment protocol and outcomes that can be achieved. Idiopathic condylar resorption is a progressive disease that can be eliminated with the appropriate treatment protocol.- - - - - - - - - - ranking = 80.363625361959keywords = open bite, bite, open (Clic here for more details about this article) |
4/123. Treatment of Class II/2 occlusion with 30-year follow-up. Case report.We report on a patient with deep bite and Class II occlusion who was 6 years of age on his first visit in 1953. The treatment took place in the 50s and 60s. An elastic Bimler appliance was used. In 1998, at the age of 50, he came in for a follow-up examination.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
5/123. Pediatric dental treatment for children with headache.This case demonstrates the safe step by step approach to treatment of pediatric patients with muscle spasm headache. If there are any neurologic signs or the LiteSplint is not effective, then a laboratory orthopedic appliance therapy may not be effective and a neurologic referral is necessary. It is always required to review the latest physical exam with the parent and physician if the symptoms do not improve in an orderly sequence. The LiteSplint acts as a screening and diagnostic aid in determining the source of head pain. For very young patients (three to six years of age) who may not be able to easily tolerate an appliance, an extra heavy coating of flowable composite that can act as a sealant on the primary molars, e.g. Revolution, may open the bite enough to alleviate headache or earache symptoms. Dental clinicians can perform a valuable service for their patients if headaches from deep bite malocclusions can be diagnosed and treated at an early age.- - - - - - - - - - ranking = 2.0324665364561keywords = bite, open (Clic here for more details about this article) |
6/123. Condylar resorption 2 years following active orthodontic treatment: a case report.We recently treated a patient with degenerative disease of the temporomandibular joint. A healthy, 12-year-old female with bilateral high maxillary canines presented for orthodontic treatment. Two years after active orthodontic treatment, at age 17, symptoms in her temporomandibular joint manifested and progressed. By the time she revisited our hospital at age 21, the patient had developed an anterior open bite with a long, slender facial appearance. Cephalometric analysis showed shortening of the ramus and backward and downward rotation of the mandible. Imaging studies revealed severe deformity and resorption of the bilateral condyles. Her occlusal and morphologic changes seemed to be caused by degenerative disease of the temporomandibular joint.- - - - - - - - - - ranking = 80.363625361959keywords = open bite, bite, open (Clic here for more details about this article) |
7/123. Extraction of maxillary first bicuspids and mandibular lateral incisors, combined with orthognathic surgery to correct a severe class II skeletal malocclusion.This is a case report of a 21-year-old female with a Class II Division 1 malocclusion. The maxillary arch was constricted with an associated anterior open bite. The lower facial height was excessive, and the mandibular plane angle was high. The treatment options were limited due to a previously extracted mandibular right lateral incisor. The patient was successfully treated by a surgical rapid palatal expansion procedure, extraction of the mandibular left lateral incisor, extraction of the maxillary first premolars at the time of a 3-piece Lefort 1 maxillary osteotomy procedure, and a bilateral sagittal split osteotomy advancement procedure.- - - - - - - - - - ranking = 80.363625361959keywords = open bite, bite, open (Clic here for more details about this article) |
8/123. Treatment of a Class II Division 1 malocclusion with a severe unilateral lingual crossbite with combined orthodontic/orthognathic surgery.A 24-year-old woman had a Class II Division 1 malocclusion with a severe unilateral crossbite. The crossbite was due partially to the maxilla being much wider than the mandible, allowing the mandibular left canine and first and second premolars to overerupt, impinging on the palatal tissue in habitual occlusion. The maxillary left segment from the lateral incisor to the first molar also overerupted producing 2 planes of occlusion. The malocclusion was treated successfully with comprehensive orthodontics, combined with a 2 piece Lefort I osteotomy procedure, a 3 tooth mandibular segmental osteotomy procedure, and a bilateral sagittal split osteotomy procedure.- - - - - - - - - - ranking = 6keywords = bite (Clic here for more details about this article) |

10/123. An adult case of TMJ osteoarthrosis treated with splint therapy and the subsequent orthodontic occlusal reconstruction: adaptive change of the condyle during the treatment.This article reports treatment for a 21-year 11-month old female patient with severe osteoarthrosis of the TMJ with a special reference to adaptive changes of the condyle during the treatment. She had severe open bite with a Class II molar relationship; she had limited mouth opening, TMJ sounds, pain, and tinnitus. Lateral tomograms showed flattening and deep erosion on the left condyle, and an MRI revealed anterior disk displacement without reduction. By manipulation and splint therapy, TMJ pain and tinnitus were eliminated, then orthodontic treatment was initiated, maintaining the splint-induced position of the condyles. After 2 years of orthodontic treatment with a multibracket appliance, an acceptable occlusion was achieved with a Class I molar relationship. On lateral tomograms after treatment, bony deformation of the left condyle disappeared and adaptive remodeling was recognized with a uniform joint space in the left TMJ. However, repositioning of the disk was not achieved. Adaptive changes or functional remodeling experienced in this patient may be due to stable occlusion, uniform joint space, and the consequent biomechanical equilibrium in the TMJ.- - - - - - - - - - ranking = 80.396091898415keywords = open bite, bite, open (Clic here for more details about this article) |
