Narrow Diameter Implants for fixed partial denture or removable: thoughts?
I have a patient with a maxillary complete denture opposing 4 mandibular teeth that are periodontally compromised #26,25,24,23 [mandibular right lateral incisor and maxillary lateral and central incisors; 42,41,31,32] as well as and other mandibular teeth #30, 29, 28 [mandibular right first molar and second and first premolar; 46,45,44] and #19,20,21 [mandibular left first molar and second and first premolars; 36,35,34]. I would like to extract #25-23 and replace with MDI narrow diameter implants and either a fixed partial denture or removable partial denture retained by the implants. What are your thoughts on this plan?

I know I'll get some flack for this but since there are teeth present, I would place 3.0 or 3.3 diameter implants using expanders and grafting. Especially since you are using a fixed bridge and the emergence profile will look better. I don't use minis and I don't like failures. Since you have teeth present so there may be enough bone to do this. The slightly wider implant are two piece so they are retrievable especially if you can have screw retention, may be tough however since these are mandibular incisors. My personal philosophy is to go for the best option long term for the patient. I see this frequently in my practice and eventually the patient gets burned by shortcuts. And believe it or not, when presented to the patient in this manner they will find a way to pay for it since they want it done correctly. What is frustrating is that a bridge gets burned at the implant site preparation stage. I would also take a look at the denture and plan for some locators for retention. Just my maverick opinion. Thanks for reading.

if I understand correctly you wish to put the 3 mid in lower anterior region to help complete the arch . everal ways of skinning a cat and depends what infection around the roots , any peri apical infection and height of bone available beyond the roots for the implants . if plenty of bone and not much infection could try and put 2/3 mid in at extraction and fit removable or fixed . I find that this is not as easy as it sounds and can cause greater patient discomfort , but is possible . lternative may be a temporary Maryland then wait 2/3 mths and then put in 3 mdi and a fixed bridge . Of course the Maryland can be left medium term if required but will get a lot of boneless . Hope this helps ,dave

I would have to see a cone beam but in my opinion a 3.0 diameter implant will serve the patient much better than a mdi mini implant and gives you the REAL option of a fixed partial denture as opposed the limited options with the mini implants. You can always placed locators on top of them as well. I would get a cone beam scan... If its shows enough bone perhaps lower the presumed knife edge ridge slightly and graft. Removable interim and then place the 3.0 fixtures. Remember none of this will be successful with no posterior occlusion. i agree with CRS - locators on 3.0 impants
