Using supplements help bone heal faster and if 3 months is enough to get abutment/crown ?

The general rule of thumb is to allow six months of healing before placing a final crown on a dental implant.Many factors, however need to be taken into consideration. Since you did have bone grafting done at the time of placement, your dentist may suggest waiting even longer before placing the final restoration.If aesthetics are an issue, your dentist may feel comfortable placing a temporary tooth on to the implant that does not have any chewing force contact until the implant and graft are completely healed.I hope you found this information to be helpful,Dr. Champagne

Supplementation shouldn't hurt anything and can help if you are deficient in vitamins and minerals per your diet.  Remember, "Supplements" only supplement, what you physically eat is primary.  Plant sources of protein are touted as best such as Spirulina, but you should also fucus on healing foods high in antioxidants and obviously the colorful vegetables etc.Your age, your overall systemic health, your current diet, your current metabolism/exercise and habits (snacks, sugar intake, oral hygiene, etc) will have an accumulative effect.  But, sometimes it just takes time.   Most of my patients will have hard mature bone in 3 months but I have had a couple that took a year!  A good dentist will read the bone during implant placement and know by feel and torque measurements the hardness/quality of your bone at the time of surgery and they will be able to give you an estimated time for "loading" or crowning the implant with the final crown.
