Bar Overdenture: Guidance on Space Considerations?

First of all you need to determine the vertical dimension to measure how much space is available. Next place the implants a little mesial to the canine region after applying a measuring caliper to the alveolus in this immediate area.(raising a flap is safest in order not to stray off the correct trajectory). The space under the bar should be sufficient to allow the insertion of an interdental brush. You can work out how much space is available from the intial VD measurement. Lots of fun and success.

Read some implant pros books.

Hi: Grab a copy of Inside Dentistry Magazine April 2012 issue(or look at it online). There is a small article on the mandibular bar overdenture that may help you. Here are some tips: For a tipical bar overdenture you need 12 to 15 mm of interarch space. You want the bar as close to the soft tissue as possible but not touching. You do not need to estimate the thickness of the gingiva over the alveolar ridge, you can wax the bar directly to a gold coping on the implant. And you do not need more space if you have a metal framework in the saddle area as this is usually the place where the greatest space exists. Adding a metal framework to a tipical overdenture is not required and will complicate things. Hope this helps.
