3mos ago got dental implant on lt & bone graft rt side i got laid off can't afford to get crown & implant etc. how long can i wait? will bg reabsorb?

Dental implant: The problem with having an unrestored dental implant is that, depending on how long you wait, the teeth on either side of the implant may drift towards the implant site. This would necessitate orthodontic treatment to re-align the teeth prior to restoring the implant. Talk with your dentist about how to maintain the site until you can restore the implant.

Until ready but....: Waiting to restore an implant fixture is not a problem. However, the space should probably be maintained with a temporary removable partial, unless the adjacent teeth are already part of a permanent bridge, an implant retained crown or other restoration. Discuss how to best handle this situation with your own dentist.

Type of bone graft: Yes, the bone graft will resorb. The time of resorption depends on the type of bone graft they placed. Some crystalline grafts, such as bovine, will take muck longer to resorb than demineralized bone allografts. Resorption also depends on the surgeon's technique, location of the graft, age of the patient, systemic illnesses, etc. A well placed crystalline graft with biologic mediators one year +.

Quite a long time...: As long as the healing abutment is not loose I do not see much of a downside to waiting to restore it. As soon as your financial situation improves i would call the restoring dentist.

Be Proactive...: Talk to your surgeon and prosthodontist about the situation. If the implant is ready to be restored, the prosthodontist can place a temporary crown to maintain the space until you can afford the permanent crown. As for the bone graft resorbing, this depends on the size, location, and type of graft that was done. You may be able to 'buy' some time but i would talk to your surgeon. Keep smiling.

No problem: The longer the better, up to 2 years then the benefit of waiting is not longer there. Periodic exam and cleaning should be done once a year to make sure your surrounding dentition is stable and healthy.

2 possible problems 1) Bone dissolves away if it's not supporting anything, and 2) Posterior bite collapse as adjacent and opposing teeth collapse into the extraction site. Talk to your Dentist about creative financing options.
