Thanks for your question. It is my opinion that your left side tmj condyle is higher ( evaluated on your attached panoramic X-ray ). This side therefore needs to be the guide in finding the correct mandibular position for your treatment.Your splint should therefore be somewhat thicker on your right side. From the clinical pictures it seems as if your left side teeth meet prior to your right side teeth on closing ( in the retruded position of your mandible ).Your splint probably needs to be redone in order to compensate for the condylar height that is missing on your right side. In addition, it seems as if you are bruxing in a left side laterotrusion (predominantly mandibular movements to the left ), a thought based upon the flattening of the right side condyle visible on the X-ray.
Sincerely,
Tore L. Hansson
