Minimum Bone Thickness on Buccal and Lingual?

I doubt you could visualize that with the naked eye, I know I couldn't.

Okay now I understand better. I like working with a online company but remember that you are the doctor and must guide them based on your clinical experience and judgement. Don't even worry about offending them, you are the surgeon! Now here is my guidelines, the minimum amount of bone is 1mm. But I like to graft or expand the bone to get more coverage of the implants. I like to look at the architecture of the site and fill in the gaps. Sometimes based on judgement I will place the implant simultaneously, but I base it on several factors, age of patient,health, comorbidities, type of procedure and most importantly how I will handle any complications, sequela or failures. Don't forget function and occlusion that's why we place implants. So the short answer is 1mm with grafting hard or soft tissue depending on the site. Also the individual implant manual can offer guidelines always important to know what you can do with the type of implant itself and it's limitations.

Ideally, the minimum buccal/lingual thickness of bone should be 1-1.5mm. But having said that, the vascularity of the bone should be taken into account. Normally ( though not invariably), the softer bones are more vascular cue to the higher content of the cancellous portion. If it's D3 bone, 0.75mm thickness would be a 50-50 call (lack of thickness versus increased vascularity). This does not include soft (D3-4 bone with poor vascularity - it'll probably come to grief - especially with existing (or a history of) poor perio health). D4 healthy bone, if primary stability is achieved, can probably function too if it bleeds sufficiently during surgery. If it's D1 or D2, & doesn't bleed much, raise a mini red flag, especially with thin bone coverage. Having said that, inform & warn the patient. Fingers crossed. Good luck.

You also want to be sure you have a collar of thick keratized gingiva, especially if you do not have optimal buccal bone thickness

Study in 2011 by Cho found the mean thickness of healed bone at the crest on the buccal surface of implants to be 1.91 mm. Implants were placed, allowed to integrate and restored. Resorption occurred until status was achieved at the 1.91 mm thickness level. Conclusion is that bone requires approximately 2 mm on the buccal, to be preserved and that if thinner, it will resorb to this level. Thinner bone has a compromised blood supply.

Minimum 2 mm. If you don't have it, make it.

The bone sets the tone........but the tissue is the issue!

Use an implant that minimizes crestal bone loss. That means something that is platform switched. Then we don't see the crestal changes like in traditional flat to flat implant designs. I would recommend the 3.0mm Astra for small sites. I agree with Dr. Montana, 2mm is ideal.

Just another agreement with what was already said. 2.0 'm bone ideally, and a nice band of keratinized tissue. Less might work in certain cases but always aim for the best.

It is not all about Quantity ...... but we will learn that quality is critical not just keratinised gingiva but attached keratinised tissue and here we need true host bone to improve the attachment . With HA graft materials it is seen that there is generally 50% less host bone ( HL Chan , HL Wang Systemic review JOMI 2013) than resorpable materials. Thus it is not about have a radio-opaque mass but host Bone. Peter

The recommended bone thickness around an inserted implant should be 2.0 mm, therefore in you use a "regular" implant (3.7 mm or more) you need at least 7.50-8.00 mm of ridge width. If you haven't this width you should regenerate or expand the ridge (i.e. split crest techniques). Other studies report that is possible, but not recommended, to accept only 1.5 mm of bone buccally and 1 mm lingually or palatally, but with these "borderline" values the procedure is hazardous and this solution is suggested only in "thick"biotypes
