Rotation axis of the maxillary molar and maximum tooth movement according to force direction

Slow and continuous maxillary expansion, molar rotation, and molar distalization.

Ectopic Molar Tooth in the Maxillary Sinus: a Case Report

Ectopic tooth eruption in a non-dental area is a rare entity, whereas in oral cavity it is most common. The ectopic development of teeth in non-dental localizations have been reported in the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity. Ectopic tooth eruptions in maxillay sinus are usually asymptomatic and found incidentally during routine clinical or radiolog...

Ectopic 3rd Molar Tooth in the Maxillary Antrum

Location of ectopic tooth in a nondentate area like the maxillary antrum is rare. A 17-year-old boy, with one year history of recurrent right facial swelling and radiographic finding of a maxillary third molar tooth located at the posterior wall of the maxillary antrum, is presented. Under endotracheal intubation, the tooth was extracted through a Caldwell-Luc antrostomy approach and patient ha...

Ectopic eruption of a maxillary third molar tooth in the maxillary sinus: a case report.

Ectopic eruption of teeth into regions other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin, and maxillary sinus. Occasionally, a tooth may erupt in the maxillary sinus and present with local sinonasal symptoms attributed to chronic sinusitis. We present a case of an ectopic maxillary third molar too...

Force magnitude and duration effects on amount of tooth movement and root resorption in the rat molar.

OBJECTIVE To test the hypothesis that there is no difference in the effect of different continuous moderate to very heavy forces on root resorption or amount of tooth movement. MATERIALS AND METHODS In the study, 10, 25, 50 and 100 g mesial force were applied to the maxillary first molars of rat using nickel titanium closed-coil springs for 3 days, 14 days, and 28 days. The molars were extrac...
