Author(s) Country Age Sex Teeth SRR Mechanics Active force system used Radiographic view Conclusion
Cacciafesta (2001) [17] Denmark 25 F 2(27,28) type-3 segment; multibracket coil spring panoramic; periapical film Teeth can be moved into anatomical sites lacking periodontium provided that the orthodontist uses an appliance that generates both constant forces and constant moment to force ratios.
Re (2001) [22] Italy 24 F 1(25) type-4 segment T-loop panoramic; periapical film The clinical findings of this study indicate that with a proper orthodontic force system, a tooth can be displaced through the sinus area, and the sinus lift surgical augmentation procedure can be avoided.
Yao (2004) [19] Taiwan 31 F 2(26,27) type-3 segment; miniplate, miniscrew elastic power chain panoramic; periapical film 3D digitizer The biological responses of teeth and the surrounding bony structures to intrusion appeared normal and acceptable. Furthermore, the periodontal health and vitality of the teeth were sufficiently maintained even after a 1-year follow-up.
Kravitz (2006) [18] USA 44 F 1(16) type-3 miniscrew elastic power chain; coil spring panoramic A supraerupted maxillary molar can be successfully intruded within the maxillary sinus cortical floor using two orthodontic miniscrews. Short-term molar intrusion can be achieved without clinically detectable apical root resorption.
Oh (2014) [16] USA 41 F 4(15,17,25,28) type-2:15,25,28 type-4:17 multibracket elastic power chain; coil spring; tip-back bend; double helical loop panoramic; periapical film; CBCT Successful tooth movement through the maxillary sinus can be achieved without noticeable side effects. New bone formation along the course of tooth movement and changes in the size and shape of the maxillary sinus were observed. Maintaining light continuous forces and moving teeth at a slow rate were key in accomplishing bodily movement and direct bone resorption.
Park (2014) [15] Japan 31 M 4(14,16,24,26) type-2:14,24 type-3:16,26 multibracket; TAD T-loop; Intrusion archwires; TAD panoramic; CBCT Spaces from tooth extractions can be closed by bodily movement through anatomic barriers such as the maxillary sinus, but in view of the proximity of the maxillary sinus floor and maxillary root tips, orthodontists must be particularly cautious when doing this.
Saglam (2014) [21] Turkey 54 M 1(25) type-3 multibracket coil spring panoramic; periapical film; Modification of the sinus floor by orthodontic treatment may be an alternative treatment strategy for patients requiring a sinus lifting procedure due to pneumatization of maxillary sinus.
Carvalho (2014) [20] Brazil 38 M 1(15) type-3 multibracket unknown periapical film Orthodontic movement is a safe and predictable procedure and may replace sinus lift and graft procedures for patients who smoke or for individuals with a history of sinusitis. The procedure also allows implant placement in an area of mature bone rather than in grafted bone, which may be a favorable factor for osseointegration.
Kuroda (2016) [14] Japan 29 F 9(14,15,16,17,23,24,25,26,27) type-2:14 type-3:15,16,17,23,24,25,26,27 multibracket; TAD coil spring panoramic Interradicular miniscrews are useful for distalizing the maxillary dentition to correct class II malocclusion. With this new strategy, group distalization with miniscrews enables a simpler treatment with greater predictability.
