Thank you for your 3 questions. Taking them in order:

1. Face shape improvement – Your two options are a plate or implants to replace your missing teeth. This would improve the support to your cheeks – just how much is hard to say.

2. replacing your top plate – implants are a definite option. However there is often not enough bone to place the implants . This would mean an extra surgical stage to create some bone . This is called a sinus lift. Once this has been done implants can be placed. Typical implant costs are in the region of £2000 to £3000 but this can vary depending on the experience and location of the dentist. There would be an extra cost for the sinus lift.

3. Extra gum to stop lines. It sounds from this that you have lost a fair amount of bone lost. This can be replaced prior to implant placement with a bone graft or gum can be added to a denture.

In cases where bone loss is a problem a well made denture with precision attachments to the remaining teeth can often be the most simple and cost effective option

Your case needs a proper comprehensive assessment and treatment plan to work out the best options for you from a restorative and financial perspective.
