Question

In laterognathy which functional apliance should be given

Answer 1

Fixed functional appliances may be broadly classified as rigid, flexible and semirigid appliances.1 The major difference between functional appliances and fixed functional appliances is probably that the mandible is forcefully postured in an anterior position with the latter, with the help of interarch anchorage using the maxillary denture base as the anchor unit. As discussed in many chapters in this book, the use of temporary anchorage devices such as miniscrew implants (MIs) to provide the anchorage for fixed functional appliances avoids the unwanted effects of using teeth as the only anchorage. This chapter describes the use of the Twin Force Bite Corrector (TFBC), which is a hybrid type of fixed functional appliance,2 together with direct and indirect anchorage supplied by MIs.
