1/4. A comparison of autotransplantation and orthodontics in a case exhibiting two ectopic upper cuspids.Bilateral severely ectopic maxillary cuspids were treated differently on each side. On one side the ectopic cuspid was moved into position orthodontically, and on the other, the ectopic cuspid was positioned by autotransplantation. The orthodontic positioning took a long time and the tooth exhibited root resorption. Treatment time for the autotransplantation positioning was far quicker, and there was no resorption nor were there any other side effects.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
2/4. Interceptive management of eruption disturbances: case report.The aim of the present report is to describe a case of a patient with eruption disturbances of an ankylosed lower primary second molar, delayed development of a maxillary permanent canine associated with an odontoma and a class III dental malocclusion. In such a case the objectives of treatment are: to prevent impaction of the lower second premolar and tipping of the lower first molar; to establish correct anterior overbite and overjet and to control the development of the permanent upper canine.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
3/4. Orthodontic treatment of a traumatically intruded tooth with ankylosis by traction after surgical luxation.This report presents the treatment of a patient with anterior crossbite and displacement of ankylosed maxillary and mandibular right lateral incisors. The maxillary lateral incisor, which was traumatically intruded, was successfully treated with 2 surgical luxations followed by orthodontic traction. The mandibular lateral incisor, which was avulsed and replanted, experienced replacement root resorption during orthodontic treatment and was ultimately extracted. Two years after active orthodontic treatment, the occlusal results were considered satisfactory.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
4/4. root resorption and ankylosis associated with guided tissue regeneration.BACKGROUND: root resorption and ankylosis have been reported rarely as sequelae to guided tissue regeneration (GTR). The authors describe a clinical case of root resorption following GTR that involved the use of a bioabsorbable membrane. CASE DESCRIPTION: Two years after GTR was performed on a Class II furcation defect, the clinical examination revealed root resorption reaching the pulp chamber. The furcation defect was filled with epithelium and connective tissue, which contained inflammatory infiltrate and fragments of the membrane. The authors also observed areas of the tooth that exhibited points of ankylosis and root resorption. CLINICAL IMPLICATIONS: Clinical trials have reported favorable clinical and histologic results with GTR. However, this case report, along with other case reports and studies in animals, suggests a high risk of root resorption and ankylosis after GTR, which could limit the indications for this technique.- - - - - - - - - - ranking = 1keywords = bite (Clic here for more details about this article) |
