Efficiency of a skeletonized distal jet appliance supported by miniscrew anchorage for noncompliance maxillary molar distalization

Noncompliance screw supported maxillary molar distalization in a parallel manner

“…Thereby, screw supported intraoral distalization devices have gained popularity in the recent past. 1,7,9,31 The results of these studies were very satisfactory in that the molars were moved distally and a Class I relationship was achieved in an average of 6 to 9 months. However, a significant degree of distal crown tipping of upper molars was observed during distalization which consequently creates the need for additional time, extra uprighting mechanics and overcorrection of the molar relationship.…”

“…Although the force was applied palatally from the center of resistance of the molars on frontal view, the unique design of the appliance managed to resist rotational movements in that the upper right and left first molars showed only 0.54 o and 0.74 o of distobuccal rotations respectively during distalization which were statistically non-significant while this was ranged between 2.40 o and 8.35 o with conventional and screw supported intraoral distalization appliances. 1,3,31 The role of second molars in distalization of the first molars was evaluated by many researchers and generally has been considered as a barrier in traditional means of distalization. Bondemark et al, 32 Worms et al, 33 Gianelly et al, 34 Gianelly, 35 Ten Hoeve, 36 Jeckel and Rakosi, 37 concluded that the duration of treatment would be longer, greater forces would have to be applied and more anchorage would be lost if patients had second molars.…”

Minivida İmplant Destekli Distalizasyon Sisteminin Dentoalveoler Etkileri

“…The average distalization duration was 9.5 months and the appliance showed good stability throughout the distalization period (Table 1, Number of studies examining dentofacial effects of intraoral implant supported molar distalization systems have been published in the recent years such as implant supported pendulum (24,25), skeletonized distal jet (26,27), Keles slider (28), miniscrew implant supported distalization system (31) and dual force distalizer (32). All of these studies aimed to eliminate the anterior anchorage loss, which is a crucial problem of conventional intraoral molar distalization appliances.…”

“…Bu apareylerin bir diğer avantajı da distalizasyonun nüksünü engellemektir. En sık kullanılan implant destekli molar distalizasyon apareyleri pendulum (24,25), distal jet (26,27), Keleş slider (28) ve bunların modifikasyonlarıdır (29,30). Son zamanlarda popüler olmaya başlayan bu sistemlerde ankraj anterior damağa yerleştirilen minividalar aracılığı ile sağlanır.…”

“…These appliances also have the advantage of preventing the relaps of distalization. The most common implant supported molar distalization appliances are pendulum (24,25), distal jet (26,27) or Keleş slider (28) and their modifications (29,30). In these systems which became much popular lately, anchorage is obtained from miniscrews placed to the anterior palate.…”
