Any time estimations between molar tooth pulled (bone graft added) and my use of a rpd to fill in smile line space? implants in future #13, 14.

Not enough info: Everyone's different. No possibility of giving you a personalized answer over the computer. Only the Surgeon who did the extractions and the graft can give you a healing time estimate prior to fabrication of a removable partial. Could be 6 weeks to 6 months. See the Surgeon for an opinion.

Varies: Since each case is different and each practitioner decides what's best for their patient, your question should be addressed to the team that is treating you.
