RANK/RANKL/OPG gene polymorphisms and loss of orthodontic mini-implants.

Objective: To investigate the association of genetic polymorphisms (tagSNPs type) of RANK/RANKL/OPG genes with the loss of orthodontic mini-implants (MIs).

Setting And Sample Population: One hundred and thirty-five patients of both sexes, with mean age of 48.7 ± 10 (20-76 years), were studied.

Achieving Better Function through Combining Orthodontics and Restorative Dentistry in the Case of Dental Abrasions.

This case report describes the orthodontic treatment used to prepare for restorative dentistry, aimed at the functional rehabilitation of an adult patient with Class I malocclusion, right posterior crossbite, and significant tooth wear on the palatal face of the maxillary canine to canine. The orthodontic treatment was performed with a total fixed appliance mini-expandex-type expander, associated with vertical elastics. Good dental intercuspation was obtained and enabled conditions for the restoration of the abrasions on the palatal surfaces of the maxillary incisors and canines and the tips of the buccal cusps of the maxillary right premolars and first molar.
