B.I.C. Bolton Index Calculator

B.I.C. Bolton Index Calculator is an app that determines the necessity for orthodontic treatment of malocclusion. The customer required a solution for calculating the dental arch in a quicker and smarter way. While the usual process requires the orthodontist to make a dental cast for the Bolton analysis, the app takes a couple of seconds to calculate the Bolton Ratio, and does it more precisely.


The app allows the user to enter patient’s details, such as their name, age, and the clinic where the appointment is taking place. This is especially handy for dentists that work in multiple clinics. The user can choose two photos from the phone gallery, or take a photo using the camera. The photos will be used for calculating the Bolton Ratio. Using the photos, the app measures the total mesiodistal width of the maxillary teeth, the total mesiodistal width of the mandibular teeth, and calculates the ratio of the two measurements. The app generates a PDF file with the calculated Bolton’s ratio and a photo. The results can be modified, zoomed in on the photo, and shared with colleagues.


When the customer came to Almet, he had only the idea of the app’s functions. Therefore, we’ve created the project from scratch, from design to testing. The app uses Core Graphic technologies. The project was realized by the team that consisted of the designer, iOS developer, a project manager, and quality assurance specialist.
