Full Arch Implant Bridge – “Splinted Implants”

Examples: Metal Acrylic Dental Prosthesis, Zirconia Dental Prosthesis, Zirconia Framework and Ceramic Crowns, Metal Framework with Individual Crowns

Metal Acrylic Dental Prosthesis ("Hybrid" - Precision Dental Arts)


Description:
Full replacement of all teeth of one's jaw with a fixed (non-removable) metal and acrylic dental prosthesis.  This treatment options significantly restores comfort and function to those who have lost their teeth.  Most people are able to return to nearly full function.  Usually 4 to 6 implants are required to accomplish the tooth replacement with predictable success long term.  The metal framework is used to provide adequate support, retention, and strength to acrylic denture teeth.  If designed properly the metal is not visible in one's smile.  This type of prosthesis will allow for replacement of one’s teeth up to their first molars, providing a slightly shorted dental arch (replacement of teeth to the first molars).  However, there is generally no loss in functional ability.

Advantages
:
Great function, good esthetics, fixed/non-removable tooth replacement, comfort, overall cost - most economic method to obtain excellent function

Disadvantages:
Acrylic teeth, tooth wear with time, possible staining of teeth

Long Term Maintenance: 
With time the acrylic teeth will wear. Generally, it takes about 6-8 years until the acrylic teeth must be replaced. This can be accomplished fairly easily when the time comes. It involves removing the old worn acrylic and teeth from the metal frame and resurfacing the metal with new teeth and acrylic.  Screws may loosen or break, easily repaired most of the time.  Teeth may fracture or chip which can be repaired or replaced very easily.

Zirconia Bridge ("Pretau" - Precision Dental Arts)


Description:
Full arch tooth replacement with an all zirconia dental prosthesis.  Usually a veneered layer of porcelain is applied to the front teeth to improve esthetics.   Zirconia is a very dense highly crystalline ceramic that is extremely strong.  It also requires 4-8 implants to provide adequate support for the prosthesis.  The number of teeth to be replaced with this prosthesis is dependent on the location of implant placement.  It is an additional option to replace one's teeth to a very functional and comfortable state.

Advantages:
Good Esthetics. Complete tooth replacement.  Excellent function. Excellent strength.  Not removable.  Able to replace missing gingiva.

Disadvantages:
Opacity of material limits esthetics slightly.  Cost.  Cost of Maintenance. 


Zirconia Framework with Individual Ceramic Crowns ("Zurick Bridge" - Precision Dental Arts)




This type ofprosthesis is able to replace all teeth with a single prosthesis. This is accomplished by fabricating a zirconia substructure that allows for individual ceramic crowns to be cemented onto the framework. The use of the zirconia framework provide one of the most esthetic options available.  The use of individual ceramic crowns provides a very esthetic and natural looking appearance to the final prosthesis.

Advantages:
Excellent esthetics.  Ceramic teeth.  Longevity of restorations (minimal wear with time).
Correction of implant angulation concerns.
Allows for esthetic replacement of gum tissue.
More natural feeling texture and when biting/chewing.   
Individual crowns.

Disadvantages:
Limited retrievability if something needs repaired.
Cost of maintenance if a crown requires replacement in the future.


Metal Framework with Individual Ceramic Crowns 


This type ofprosthesis is able to replace all teeth with a single prosthesis. This is accomplished by fabricating a titanium alloy substructure that allows for individual ceramic crowns to be cemented onto the framework. The use of individual ceramic crowns provides a very esthetic and natural looking appearance to the final prosthesis.

Advantages:
Good esthetics.  Ceramic teeth.  Longevity of restorations (minimal wear with time).
Correction of implant angulation concerns.
Allows for esthetic replacement of gum tissue.
More natural feeling texture and when biting/chewing.   
Individual crowns.

Disadvantages:
Need to mask metal substructure can affect overall esthetic outcome.
Limited retrievability if something needs repaired.
Cost of maintenance if a crown requires replacement in the future.
