Objective: To review a series of clinical studies demonstrating the clinical efficiency of aligners with bite ramps in the treatment of severe deep bite.
Materials and methods: In order to predictably manage the correction of deep bite with aligners, precision bite ramps on maxillary incisors have been used while posterior extrusion and anterior intrusion in the lower jaw with lateral attachments and proper levelling of the curve of Spee have been planned. Transverse correction and controlled upper and lower incisors proclination completed the treatment plan.
Results: Full deep bite correction with normal overbite was obtained in nine months of treatment by a combination of anterior intrusion and posterior torque correction, distal tipping and relative extrusion.
Conclusion: The use of bite ramps represents a valid option for the successful treatment of deep bite with aligners creating proper space for lateral sector extrusion and supporting lower anterior intrusion and controlled proclination.
