Abstract Reports have shown that molars can be distalized successfully with virtually no orthodontic anchorage loss with an intraosseous anchorage, even with fully erupted second molars. The purpose of this study was evaluating the effects of mini-screws as skeletal anchorage for upper molar distalization. In this case series, three patients needing maxillary first molar distalization,...
A fully bonded m~dtiloop wire appliance for the correction of ectopically erupting permanent molars is described. The appliance allows control in the anteroposterior, vertical, and transverse planes. Ectopically erupting first permanent molars are seen in about 3% of the population.~,2 Sixty-six per cent of ectopically erupting maxillary first permanent molars self-correct by jumping over the i...
OBJECTIVES The aim of the study was to investigate the caries-preventive effect of high-filled glass ionomer sealant in newly erupted first molars in a high-risk group. This investigation is part of a larger study amongst eight hundred and thirty-five 6-7-year-old Syrian children. METHODS Children that had 1, 2 or 3 just erupted or erupting and at least one unerupted first molar (control) wer...
The eruption of the second molars may delay therapy and lengthen treatment time. To minimize excessive prolongation, principle resistance factor elimination was applied to unerupted lower molar through a surgical incision on occlusal gingival tissue. 3.7 successfully erupted easily bonded following month, allow archwires sequence.
Odontomas are categorised into mixed odontogenic tumor that originates ecto-mesenchymally and made up of mineralised tissue. Hamartoma is the most frequent benign tumour with an aetiology. It distinguished by its sluggish growth lack aggression. "Erupted odontomas" those erupt oral cavity uncommon. They usually noticed in regular radiography can be caused a variety factors, including trauma, ge...
Ectopic eruption is the abnormal eruption of a permanent tooth that often causes root resorption of an adjacent primary tooth which can be noted during routine dental radiographic evaluation. The mesial eruption of the permanent first molar may be a local eruption problem or may indicate developmental arch circumference deficiency requiring further consideration. Early treatment is mandatory to...
Fifteen patients, eight males and seven females with a mean age of 13.32 years, were selected for unilateral molar distalization. Dentally, all presented with a unilateral Class II molar relationship. The subjects were all in the permanent dentition with second molars erupted and with a well aligned lower dental arch. For maxillary molar distalization a new intra-oral appliance was developed, t...
BACKGROUND/AIM It is considered that the shortage of space is the major cause of the third molar impaction. The aim of this study was to establish the frequency of insufficient lower third molar eruption space in Serbian population, to question the differences in this frequency in the subjects of different age, to determine the influence of the lower third molar space (retromolar space) size on...
