Titanium and Chrome Cobalt Reinforcement Technologies
Popular and Affordable Dental Bridge Alternative
Although mini implants are a popular choice for patients seeking a snug denture fit with the least amount of invasive surgery, traditional larger size implants typically offer more treatment options for a wider range of patients.
Today's advancements in dental products and procedures provide more choices and flexibility in rebuilding or replacing dental function that has been lost.... at cosiderable cost savings compared to the choices available just a few years ago.
Traditional Implant Physics
Mini implant devices normally require healthy, dense bone for successful placement and endurance. The mandible, or lower jawbone, is very dense and as such, mini implants are used predominantly in the lower jaw for securing a denture.
The upper jaw, however, is usually not as dense (more porous) which can prevent implant placements from succeeding for many patients. Bone augmentation, or grafting, for mini implants in the upper jaw is not usually recommended.
Standard Implants + Locators
Standard (non-mini) implants are larger in diameter and length. Although the degree of invasiveness (preparation of the implant site) correspondingly increases with the size required for ideal function, denture implants are larger than mini's yet can still require only minimal surgery.
Retention versus Support
Traditionally, mini implants keep dentures in place (retention) and help to conserve bone quality (no large scale bone loss as with regular non implant dentures). The denture still "rests" somewhat on the gums and jawbone ridge.
Larger implants allow the dentist to shift the "load" that normally occurs with normal biting and chewing directly to the implant devices, thereby providing more bone stimulation and nearly eliminating wear and tear on gum tissues.
Unlike a conventional bridge, a titanium or chrome cobalt reinforced denture prosthetic with locator attachments allows the patient to remove this type of bridge product at will, making oral hygiene activities easy to accomplish.
|Healthy Implants - But Wrong Type
The patient presented here had been wearing denture products for quite some time. Although implant supported, they were loose, uncomfortable and didn't feel natural.
She felt like her dentures "looked like" dentures and was self conscious about her smile.
The configuration of dental implants and abutment devices in her upper jaw did not seem to provide the stability that could enable her to bite into or eat anything she desired.
Because of the implant spacing and denture design, unpredictable flexing of the upper denture occured.
|Changing Implant Interfaces
Non Invasive Implant Modification
The implant interfaces were altered to accommodate a denture prosthetic that would incorporate, for this patient, a chrome cobalt metal mesh device.
This reinforcement material creates a denture that has stability and functional value that is nearly identical to titanium bridgework.
A custom designed reinforcing mesh is first molded and adapted to follow the contours of the patient's bony ridge and to mount onto the dental implants.
Bridgework Function at Denture Pricing
The unique casting process incorporates numerous perforations thereby assuring a light weight product that provides rock solid resistance to flexing... under any biting force imagineable.
|Sturdy Chrome Cobalt Reinforcement Metal
Once a perfect fit is made for the reinforcing mesh to follow the natural contour of the patient's jawbone, complete with the locations for attachment, a custom dental lab fabricates the prosthesis.
Since the patient wanted a denture product that didn't look like a common denture, custom IPN denture teeth were individually selected to create replacement teeth that looked natural, similar to porcelain crowns.
|Metallic Core Denture
Lower Jaw Implant System
The existing configuration of implants and mounting bar in the mandible was not altered. A replacement prosthetic was fabricated using custom IPN denture teeth that matched the quality, contours, sizing and color shading of the new upper denture teeth.
Teeth were individually selected to assure the cosmetic outcome desired by the patient.
The cosmetic lower denture incorporated attachment devices that provided a very snug fit, compared to what
the patient had before in her older dentures.
Lower Implant Attachment Bars
Snap In Denture Features
As can be seen in the adjacent photos, the upper denture has attachment devices that are different from the lower denture. These two different types of snap-in devices create the tightest fit possible.
Patients can be provided with special tools and user replaceable attachment parts that make replacements easy and do not require additional dental visits.
Dental implants have long been considered the Gold Standard for tooth replacement solutions. Removeable prosthetics that are designed to attach directly to implant systems enable patients to exercise a degree of oral hygiene that many patients with fixed bridges are unable to achieve.
Titanium implants require as much, perhaps more, attentive care to assure bacteria and food debris don't accumulate around the implants or attachment bars.
|Snap In Lower Denture Fittings
Creative denture implant solutions assure easy access for routine cleaning with common flossing products and even water irrigation devices such as the WaterPik.
Implant failure due to bacteria and plaque build up (yes, plaque can accumulate on implants) is virually eliminated with implant supported prosthetics, providing a reasonable opportunity to have implants that last a lifetime.
|Cosmetic Denture Prosthodontics
Cosmetic dentures secured with implant anchoring systems are delivering a quality of tooth replacement that wasn't achievable just a few years ago.
Custom denture teeth, attachment systems for nearly any bone condition and the choice of chrome cobalt or titanium core prosthetics can deliver the cosmetic results and endurance that, at one time, were considered possible only with conventional bridgework.
