Aims
To investigate mandibular motion in six degrees of freedom before, during and after twin block treatment in one individual.
Methods
The appliance was worn for eight months, and motion recordings, using a 12-camera opto-electric system, were captured prior to placement of a twin block appliance and 2, 4, 14 and 52 weeks after insertion.
Results
The wide variations in mandibular motion that accompany twin block wear disappeared post-treatment, except for an increase in anteroposterior movement of the mandible.
Conclusion
Twin block therapy appears to affect mandibular motion temporarily.
