Developing malocclusion in mixed dentition needs various model analyses to lay down a progressive treatment plan. Numerous mixed dentition analyses are available in literature and thus creates the dilemma among Pediatric dentists to choose the one. The use of modern technology in dentistry eases out the workload of dental professionals. This lecture would explore the use of such technology i.e. a new Mobile app ‘Ortho Assistant’ which provides 3D solution of mixed dentition model and cephalometric analysis. The App uses logical algorithms to calculate various space analysis thus easing out multi-step complicated calculations. Not only calculations, but documentation and direct comparison of various results using various mixed dentition can be done on the result pages in the downloadable form, available in the app.
