Dentures and Tori don’t Mix!

When is it ok to cover a maxillary tori with your denture base?  Sometimes medical issues preclude surgical removal of tori.  Sometimes a patient just doesn’t want to go through the surgical procedure.    The key to a successful denture in this case  is whether or not an effective post dam can be created behind the tori. If not, the denture will not have retention. The tissue over palatal tori tends to be thin and  pressure from the denture base can cause a sore spot so be sure to provide at least 2 mm of thickness over the tori to insure that you will have enough acrylic for adjustments without perforating the base….denture tori

Managing Iatrogenic Periodontal Disease

                                                  Figure 1

Periodontal disease has known etiological factors which include plaque and calculus which harbor bacteria. This multifactorial disease process is primarily a chronic inflammatory response to toxic bacterial byproducts which are the result of a lack of effective oral hygiene procedures. This is particularly true in cases of iatrogenically induced periodontal disease of the hard and soft tissue caused by restorations which violate  known biological principles.  Ill fitting restorations harbor plaque and calculus and frequently exhibit residual excess cement. The patient nor the clinician can accomplish effective oral hygiene which would maintain an acceptable level of gingival health.   Crown preparations which violate the biologic width,  are over contoured, and/or have uncleansible bridge or splint connectors cause chronic inflammation which destroys the supporting tissues.   Continue reading

Occlusal corrections on multiple crowns can be a daunting task.  Even with the most meticulous technique, there are times when you have to do more than “just a little” adjustment to your full mouth cases or you may just want to really detail the occlusal scheme of your masterpiece.  Do you make these adjustments in the mouth on what some call the “final articulator”?  I think everyone would agree that it can be difficult and sometimes impossible to make final adjustments of multiple crowns intra-orally, so how can one utilize an indirect approach to the tedious task of perfecting the occlusion?   Continue reading
