Molar Protraction: Orthodontic Substitution of Missing Posterior Teeth

  • Chapter
  • First Online:
Temporary Skeletal Anchorage Devices

Abstract

The main focus of this chapter is on the closure of missing posterior spaces by protraction of the second and third molars using TSAD (Temporary Skeletal Anchorage Device). The missing spaces are from upper first molar (U-6), lower first molar (L-6), and missing lower second bicuspid with extraction of deciduous second molar (L-E). In this chapter, cases of second molar extraction or missing will not be discussed.

Total 110 cases of missing teeth were treated (U-6: 27, L-6: 63, L-E: 20) and three cases have failed; therefore, the success rate was 97.3 %. In many cases, the impacted third molar erupted well and it became usable. This treatment can replace traditional treatment method, such as bridges or implants. If we can use the third molar, which was to be discarded, the significance of this treatment will become great.

When patient has missing tooth, orthodontic evaluation should be done prior to other treatment options, because orthodontic treatment course becomes much more complex and difficult for the cases when implants or bridges are already applied.
