So this question pertains to fixed vs. removable anterior sagittal appliances and the pros and cons of each.
This is an 8yr old patient. My concerns are that he does not have any space for the eruption of the mx laterals (still primary teeth with no mobility) and an anterior crossbite at tooth 21. He is class III skeletal (Wits -3.7) and has a retrognathic maxilla (N-ANS is 48.2), photos attached.
My goal for this treatment is to:
- a) Correct his anterior crossbite
- b) Create room for the mx lateral incisors
- c) Keep the md locked (use mx central incisors to keep it locked) during growth to prevent advancement of md (no posterior occlusal pads, but use bite turbo to help jump the crossbite and then remove them right after the jump is complete)
The appliance I would like to use is a mx anterior sagittal, but I don’t know if we can use a fixed mx anterior sagittal (mom doesn’t seem to think the patient will be very compliant). This patient’s case almost looks exactly like the case on page 82 of Dr. Rondeau’s Early Treatment book and he used a removable anterior sagittal. However the book says to use fixed for only deep bite cases and Class I skeletal and dental. My main question is can I use a fixed anterior sagittal for this case? And what are the problems with using a fixed appliance?
