Palateless Upper Denture Dentistry
Achieving The Best Attachment InterfacePalateless dentures have become a popular treatment choice for patients who are accustomed to standard dentures and want something better and more comfortable.
An increasing number of implant oriented attachment technologies (Zest locators, O-ring locators, Locator Bars, Hader Bars) coupled with improvements in fabrication of metal core (solid, mesh) dentures enables Dr. McFarland to design removable prosthetics that are an excellent functional and cosmetic alternative to expensive bridgework.
Critical Components for the Best FoundationThe types of dental implants selected by the dentist and patient can be critical for achieving the best long term result in terms of functionality and comfort.
The characteristics of a patient's upper jaw bone (the bony ridge) are highly variable. Height, width and porosity can vary, quite literally, in multiple locations on a patient's jaw. The patient's history of extractions, old tooth treatments, oral hygiene habits and occlusion factors impact the health of bone.
Most accomplished implant dentists and Prosthodontists know how to individually select implants with different diameters and lengths to create the best advantages of healthy bone along the bony ridge.
Characteristics of bone level: Most denture wearers understand that to have a snug denture that doesn't rock back and forth or move while eating requires a fairly level ridge of bone. Long term denture wearers are also aware that the bony ridge will wear down over the years.
Attachment devices serve to maintain the snug fit that can make nearly any denture "feel" like a fixed bridge. Bone tissue that is significantly worn down can be augmented with graft material or custom placement of the attachment devices can be used to minimize grafting.
Unlike fixed bridgework, denture retention devices require a level of precision that assures the biting forces are not only fairly distributed but occur simultaneously. Otherwise, an implant locator retained denture can literally pop off of the attachment devices.
The acrylic flange material of a locator attached denture must provide a degree of support that dovetails with the retention characteristics of the attachment device. Errors in flange design can also cause an undersirable fit.
Case Study: Sloppy Fitting Upper Palateless Denture
It can be seen immediately that two of the implants are not very parallel with the overall implant layout. Notice too, that width and height of the patient's jawbone has influenced the placement of implants that will cause an imbalance of biting forces.
Conservative RehabilitationA thorough prosthodontic analysis of the patient's bite forces, occlusion and tissue characteristics resulted in a required revision in the placement and alignment of the implants.
Locator Bar Attachment SystemLocator bars are segments of titanium that have two interfaces. One interface, on the underside, matches the configuration of implants in the jawbone while the upper surface provides attachment points that correspond to the fittings that are mounted into the underside of the denture.
Metallic CoreThe next picture in the treatment series shows the metal framework attached to the Hader Bars. The locator housings are mounted onto the metal frame.
The pink wax material is added incrementally for accurately creating a denture and tooth height that normalizes the patients bite, both in terms of function and cosmetics.
Metal core fabrication of a palateless denture with a rock solid attachment system offers the convenience of a removable prosthetic with the durability and function that approximates the characteristics of a fixed bridge.... yet at a fraction of the cost.
Convenient Snap In TeethA properly designed and reinforced palateless denture coupled with an optimized attachment configuration provides patients nearly any cosmetic result they desire, matched with dental function that is second only to a fixed implant bridge.
