All those implants/money, and all the patient gets is two poxy little Hader clips for retention-no anterior rotation stop and a big bulk of bar that does nothing else. Hader bars are a bad solution to start with and will give you many issues here. There are better solutions. Talk with your lab about what else they can do. ■ 7/13/2020 velogeek Member Since: 04/15/10 Post: 7 of 47 Also, once the bar wears-and it will wear-it will need to be remade at significant cost. Any time you use a bar with retention, you want the ability to replace the attachments as they wear. ■ 7/13/2020 florida gator doc Member Since: 07/10/05 Post: 8 of 47 Multiple issues here. Poorly planned implant positioning as there is not adequate prosthetic space for a bar-overdenture. Sounds like this was a plan B option to a fi xed-implant bridge. The bar has to go directly to the implants as there is not enough space for abutments. This is a compromise as there will be misfit at the implant level closer to the bone. The anterior implant has failed and requires removal. The marginal bone loss on three of four implants is concerning. Why were wider diameter implants used (4.6 mm)? If you proceed with a bar-overdenture, the prosthetics will be compromised, and the implant prognosis will be questionable. I recommend going back to the drawing board and work up the case prosthetically. Are you working with a perio/OS or did you place the implants? ■ 7/13/2020 VolMan Member Since: 10/12/14 Post: 11 of 47 A Hader Bar condemns the prognosis of the bar for reasons the geek is bringing up. A milled bar with retentive attachments that are tapped can literally survive a lifetime by simply unscrewing and replacing those retentive attachments. This case is also not showing the overdenture sub-frame on top of the bar which will add another restorative space layer to the equation. ■ 7/13/2020 florida gator doc Member Since: 07/10/05 Post: 12 of 47 If the implants were healthy would you consider a telescopic overdenture? Might not even have space for that? ■ 7/13/2020 Reddy DDS Member Since: 03/30/13 Post: 21 of 47 Why do you have to do a bar here with all the issues you have? Just do a Locator overdenture. It will look great, should have plenty of retention, cover the rugae area in thin metal frame for some support if patient does not like plastic on palatal vault. Only issue I see doing Locators is that your implants may be a little too close to each other but hard to tell. And if finances are not a concern, then send the patient for some new grafting/ implants in anterior and go fi xed prosthetic route. ■ 7/13/2020 26 SEPTEMBER 2020 // dentaltown.com DT0920_MB1_AG_V2.indd 26 8/20/20 10:06 AMhttp://www.dentaltown.com
