Aim: To evolve a new cephalometric estimation called the MKG angle using three skeletal landmarks—point key ridge (KR), point M, and point G to evaluate the sagittal relationship between the maxilla and mandible. Materials and methods: A total of 60 pretreatment lateral cephalograms were selected and segregated into classes I, II, and III groups on the basis of ANB angle, Wits appraisal, and W angle. The MKG angle was constructed between the lines drawn from point M to point KR and point KR to point G. The MKG angle was measured to calculate the mean and the standard deviation. Results: After using the one-way analysis of variance and the Newman–Keuls test and running ROC curves, the results showed that an MKG angle in the range 51º–59º can be considered to have a class I skeletal pattern. The MKG angle more than 59º indicates a class II skeletal pattern and less than 51º indicates class III skeletal pattern. Conclusion: The MKG angle can be used as a dependable marker to assess sagittal jaw discrepancy.

The Forsus appliance is one of the most commonly used rigid fixed functional appliances in the correction of class II malocclusion. It is often seen that parts go missing with regular usage of the appliance. Replacement of the same is expensive and also requires a large inventory. An innovative low-cost and easy option for lost or broken split crimps is described in this article.
