Firstly what is space maintainer... something which fills up space and do not let other teeth to change positions so that you can have Implant or Bridge in future. In my Opinion Removable Partial denture ( Valplast ) itself is Space maintainer in your case... go for it. arrange your finances and plan for good implant as they are costly ranging from 50 to 80 K.

Space maintainers are only used in the growing period when the milk teeth fall off early or ar removed early to maintain the space for the permanent teeth when it comes out. For missing permanent teeth, you will need to go for fixed or removable prosthesis/ bridge or implants.

Yes, You can use space maintainer for permanent missing tooth, but it is always advisable to get it replaced with prosthesis to maintain the harmony and alignment of the teeth.

As the name suggests a space maintainer is not an replacement option, it is just a temporary treatment modality used to preserve or maintain the space until a permanent restoration is planned. You can use a space maintainer but not for long. I would advise a permanent replacement option only as you are young. Getting it done now would be best instead of delaying.

Best temporary space maintainer is Removable partial denture

You can get a removable partial denture as space maintainer. You can use it as long as you want.
