Can I change the shape/lengthen my dental implant crown? (Photo)

Bonding agents do not adhere strongly to porcelain crowns. So, it has to be renewed or if they can be removed without any damage, they can be reshaped in dental laboratory.

The answer is no. Composite does not bond well to ceramic which is what you would have at this time. The crowns will need to remade if you wish to have them lengthened.

At my practice, I use digital smile design, mock ups, and provisionals as safeguards to ensure the patient gets the chance to try their new smile before it is permanently cemented on. Though techically it IS possible to reshape a crown after it is placed, it all depends on the material used and also on how much room was left on the porcelain for reshaping. Typically, if a patient does not like either the color or shape of a crown AFTER it is already permanently cemented, it will essentially need to be redone.
