How much bone is needed for a dental implant to be placed? And is this bone criteria the same for each part of the mouth? For instance, can an implant be placed for severe bone loss in one area, such as the lower front jaw)? Thanks.

How Much Bone is Needed for An Implant?
Hi Sherry,
The quantity of bone needed for an implant to be placed is the same as the amount that was normally there when you had the tooth. If you are asking what is the "minimum amount of bone needed" for an implant, then I would say that most of the authorities in the literature agree that there should be a minimum of 10 to 12 millimeters of bone in length, and a minimum of 6 millimeters in width of bone, with wider width preferred in the molar regions to better support the biting forces.
There are techniques that you can use to place implants in more deficient areas that would increase the complexity and expense of the procedure.
There are also implant companies that make "short" implants but these are not widely accepted by implant dentists in general.
For cases with severe bone loss, you have to look at each case individually, and I would recommend contacting an experienced implant dentist for what would be best for your particular case.
Good luck!

The Amount of bone needed for a dental implant
Hi Sherry
An implant 10mm long required a 2mm. space separating it from vital structures (nerves, sinus,etc.). It should be a minimum of 1.5mm. from an adjoining tooth and 2.0mm. from an adjoining implant. There should be 2.0 mm of bone labial and lingual to the implant.
I hope this helps.

How Much Bone Is Needed
Dear Sherry: My recomendation is to find a very experienced implant dentist. This dentist should evaluate ALL of your teeth and how they function in your mouth. Bone volume is determined by a Computed Tomography Dental Scan. Implant choice and need for grafting is determined by the scan and the conditions of all the teeth in your mouth and by your expectations for the resulting treatment. Without looking at all teeth in your mouth, we do not know if we are treating you correctly. How to find an experienced implant dentist? Ask questions as to years of experience and ability to show you completed cases of similar treatment as you need. An experienced implant dentist will be able to do this easily.
Sincerely
Dr. Leonard H. Smith
