Heavy Bite Strength is limited to thickness of acrylic. Can do combination steel and Cu-Sil® cases.
Aversion to Bulk Lower free-end with closed labial can affect overt appearance if thin-lipped. Try with 2 layers of base plate wax in vestibule.
Too Many Teeth This will result in a weak appliance. Cu-Sil® is at its best with few teeth. Recommend some extractions. Minimal resorption will occur across gap.
Severe Under-Cuts Block them out. Should get plenty of retention otherwise from Cu-Sil® clasps.
Thick Muscle Attachments Can result in displacement of partial. A roofless upper might be in order.
Shallow Plate Needs stability of ridge to stop lateral stress.
Upper Partial Upper anteriors are often unsatisfactory if open smile line.
In A Hurry Can not rush the technique.
