Summary
Crown lengthening surgery is done when a tooth needs to be fixed with a crown. Sometimes, not enough of the tooth sticks out above the gum to support a crown. This can happen when a tooth breaks off at the gum line, or when a crown or filling falls out of a tooth and there is decay underneath. To place a crown, the dentist needs to expose more of the tooth. This is done by removing some gum tissue or bone.
After surgery, the area will heal in about three months. Then, making a crown can begin. This healing period often delays the delivery a final crown. This study is investing a way to make the final impression at the surgery to expedite the delivery of a final crown.
