All on 4 or 6-8 implant supported crown and bridge prosthesis?

Last Updated: Aug 03, 2016

I am planning a fixed implant supported prosthesis in the lower arch in this patient. The amount of bone available on left posterior region is limited, so I will not be able to place more than 7.5 mm length fixture. The root pieces of lower anterior teeth will be removed and immediate implant placement has been planned. Few points I am worried about:
1) Placing too short implant in posterior region (7.5) can lead to an unpredictable result especially with opposite natural dentition
2) To go for all-on-four hybrid prosthesis or to place 6 – 8 implants and go ahead with crown and bridge prosthesis?
3) I have never done an all on four case. I will have an expert place the implants, of course.
4) Also I have never placed less than 8 mm length implants, so this is a concern.

Please give your valuable inputs and help me plan the case with maximum predictable results. Thanks.

I think all on four is a safer bet, if done by an expert ofcourse.

All on 4 will be a good n predictable option for this case

Plan it carefully. Looks like a combination syndrome but can see the anterior of the upper arch.

MIKE MY SUGGESTION IS PUT IN AS MANY IMPLANTS AS YOU CAN 6-8 SINCE SHORT WIDE IMPLANTS ( SAY A 5X7) IN THE POSTERIOR HAS GOOD SURFACE AREA. What happens if your all on 4 becomes an all on three. I WOULD RATHER HAVE AN ALL ON 8 BECOME AN ALL ON 6 OR 7.

I agree with Bruce be careful. By the way; more implants is not better. Good luck!

Yes i think i will carefully plan it. Being a prosthodontist i will make sure of the interarch space and go ahead with all on 4 hybrid prosthesis.

Dr. Anthony Sclar's ALL ON 4 course offered in Miami is a very informative course if you haven't done any.

Also, you may want to look into doing it guided. I have used nSequence and the results were nice.
