How long to wait before implant placement in grafted maxilla?

Place at 4 months or you may find that it has started to be removed as is the Bodies function to remove dead bone by Osteoclastic activity and or sequestration . Expansion with particulate grafting may be a better long term solution. Peter

In respose to your question; Due to bone turn over and remodeling and based on that this is an autogenous graft; you should not wait more that 6 months. For the body this bone (grafted)needs to be turned over becuase it does not have osteoblastic properties. And also consider progresive loading when doing the prosthesis in order to harden the gafted area. Thank you for your question and accepting my humble opinion.

An iliac crest graft for a 5 mm wide ridge, wow! If any you should have used mandibular or calvarian grafts. But I totally agree with Peter: autogenous grafting is reserved for the totally atrophic jaw (say 0-3 mm or no crest at all) and that a ridge split could have been the treatment of choice here. Go easy on autogenous grafting, it may look heroic, I suppose you' re a young and eager OMS, but you will find out that less is more in surgery... Your patients and referring dentists will appreciate it.

My humble opinion is not to wait more than 3 months that are adequate for bone bridging. You should take into account the high rate of iliac crest grafts resorption. Initial 5 mms can usually be properly handled with a split and expansion. Give a thought to use bone collected from implant sites to graft on buccal. Thank you for your question and for the opinions expressed here.

Wow iliac crest bone for a 5mm ridge, I would have expanded it. I'm confused about the four month timeframe, often I will wait longer 6-8 months with my DBMS and autologous bone with the Titatium tray technique is six months.Non simultaneous implant placed sinus lift is six-eight months. My rule of thumb is four months but sometimes a patient will return for implant placement a year later and be fine. I guess I need the rationale here since my experience has been with rib and iliac crest for old edentulous cases which have a lot of resorption. Iliac crest has live cells and is a "true graft". Is this patient wearing an ill fitting prosthesis which could be compromising the graft allowing for resorption. I also see unloaded implants that are fine over time, remember that an implant is inert no PDL and stress/ strain is not the same as a natural tooth. There is always resorption we used to overbulk the graft to allow for this. I think four months is not enough time and the implants will be in soft bone, always important to have the implant apex in nascent non-grafted bone. Sometimes this stuff works we really don't know why. By the way a rib takes three years to go away. I'm finding that provisionals can greatly contribute to the bone resorption during healing!

3.2x10 reactive by implant direct would have solved this without any grafting.
