Study Overview
Brief Summary
Functional Bite Turbos made of composite are prepared intraorally. Although this method saves the extra laboratory procedures. A high loadbearing composite resin (Anabond Blu-Bite resin, - flexural modulus 10500MPa,Compressive strength 420MPa, Diametral strength 78MPa) is used to build theturbos. Anabond blu-bite is a lightCure Radiopaque Composite. It is a highly crosslinked polymeric materialcomposed of a mixture of two or more macromolecules which are essentiallyinsoluble.
Since the average height of the turbos was around 4-5mm, Someamount of composite is scooped and packed at the base of Teflon coatedcomposite carrying instrument. Composite carrying instrument having the uncuredcomposite then carried intraorally to the respective dental arch and thenpressed tightly against the occlusal and bucco-lingual surfaces of the teeth.Every care is taken to see that the composite block is snugly fitted over therespective dental arch. Once the fit is assured, it is then held in the sameplace and then photo-cured from all sides for 20 seconds. The same procedure isthen repeated for each of the remaining three quadrants until composite turbos areglued onto the occlusal surfaced of each of the first premolars.
The turbos for the maxillary arch are made with the apexroughly lying straight above the distalmargin of the maxillay first premolars.The inclines (45 degrees) of the turbos slope downwards towards the mesial sidewhere it meets the tooth at its mesial margins.
The Turbos for the mandibular arch are made with the apexroughly lying straight above the mesial margins of the mandibular first premolars.The inclines (45degrees) of the turbos slope downwards towards the distal sidewhere it meets the tooth at its distal margins.
After curing of the turbos, routine methods of polishingand finishing of turbos done by micromotor composite finishing burs. Any sharppoints or edges are eliminated to see to it that smooth, shiny and hygienicturbos, non-irritable to the oral mucosa remain in the mouth.
All the necessary instructions pertaining to oral hygienemaintenance are given to the subject. The patient is instructed to avoid hardand a sticky food that may dislodge or break the Turbos.
After initial check, the patient is recalled after threeweeks. All points pertaining to maintenance of the Turbos were re-explained andcorrect lower jaw movements.
Thereafter each patient was recalled after every fourweeks. At each clinical visit, it was confirmed either from the parent or fromthe patient as to whether there was any discomfort for mastication, speech withthe appliance. Debonding of any of the bite turbos was checked for andimmediately repaired.

- •2.All patients with early permanent dentition with prepubertal growth spurt /circumpubertal growth spurt.
- •3.Patients of either gender 4.Both the dental arches well aligned and did not demand the Prefunctional phase.
- •5.Skeletal Maturity Analysis has been done for all subjects through cervical vertebral maturity index of Hassel and Farman (CVMI) and MP3 analysis.
- •All subjects were either in stage 3 or stage 4 of CVMI These two skeletal maturity indices were selected as they give the amount of potential percentage of growth completed or remained.
- •Above two indicators showed that the subjects were in about 30-45% of potential growth is remained.

- •8.All subjects were free from symptoms of temporomandibular joint disorders.
- •10.All patients who understand the treatment plan and are ready to give written Informed Consent.
- •11.All patients ready to complete the scheduled Follow-up 12.Functional, Clinical and Cephalometric evaluation suggested the functional retrusion of the lower jaw.
