Can orthognathic surgery restore vertical dimension?

Doctors can come up with any number of solutions. The best place to start would be your dentist. They know your situation and any structure issues you may have from what they've seen in your previous visits. Discuss this next time you go. They can explain your options along with associated costs and any upkeep required by you. Some of your options may involve other specialists but in general if the problem stemmed from teeth being removed the easiest option is probably as simple as a partial implant or something you can take out/insert on your own. So start the process with your dentist and they can show you your options.
