In the vast majority of situations a complete dental implant restoration can be done on the upper arch. If the jawbone needs to be augmented due to resorption, then there are multiple bone graft techniques that can be employed. If the maxillary sinus has dropped and there is insufficient bone height, then a sinus lift can be performed to create the necessary jawbone height.It is only when there is extreme loss of jawbone due to severe resorption that it might be very difficult or even impossible to graft enough bone to properly support implants that will withstand the tremendous forces placed on them during function.I hope this information was helpful,Dr. Champagne
