Orthodontic treatment with Invisalign® can produce a high quality treatment outcome. As in all orthodontic methods, however, there is a steep learning curve. The most important factor is for the clinician responsible for the case to take full control when planning and working with the case using the ClinCheck software. Since aligners are removable, another important factor for treatment success is, of course, patient compliance. In moderate open bite cases, when vertical control is extremely important, in the opinion of the author, Invisalign® is now the preferred treatment choice over fixed appliance treatment.

CPD/Clinical Relevance: To understand that it is possible to perform high-quality orthodontics with Invisalign®. However, to achieve good results, it is important to take full control in the ClinCheck process when planning the treatment.


The Invisalign® system uses a series of computer-generated, clear, removable aligners to move the dentition. Each aligner should be worn for 20−22 hours per day and is designed to move a tooth, or groups of teeth, by about 0.15−0.3 mm. The aligners should be changed, and movement advanced, every 1−2 weeks to allow satisfactory progress towards the end result.

The final treatment goal is decided by the clinician within the software program ClinCheck® Pro, which is now completely interactive. ClinCheck® Pro was introduced in 2014 and consists of a toolbar with 3D controls to be able to adjust each tooth directly, in all three planes of space on the 3D model. Before ClinCheck® Pro was introduced, all communication with Invisalign® to determine the final tooth position was made in writing. This meant that, before 2014, the clinicians did not have true control of the ClinCheck (CC) process, which resulted in much less real control of the treatment aim and certainly of the treatment outcome.
