Placement of Implants in complete edentulous arch with all teeth missing should start with the end result in mind. Successful placement of Implants completes the first baby step of bringing a patient without any teeth into full dentition. Then comes the major pertinent question for both the dentist and the patient as to what kind of teeth to be used in the fixed denture that would be a perfect balance between esthetics; comfort and chewing ability along with stress bearing abilities for longevity of prosthesis and underlying bone preservation.
Unlike removable implant overdenture of earlier ; modern dentistry provides various different options nowadays for implant-supported restoration that include:
- FIXED CERAMIC TEETH :
The most esthetic of full arch implant prosthesis ; this prosthesis looks very similar to most traditional fixed prostheses .
Fixed Implant supported prosthesis can be screw retained or cement retained based on the position of the screws. They involve ceramic (porcelain) teeth over a base that can be made up of zirconia; Co-cr metal; titanium or peek material. In cases of excessive bone resorption; use of pink ceramic helps balance esthetics to a certain extent.
An approximate cost of the fixed prosthesis for both arches together would amount to – 2.5L
Placement of ceramic teeth require more than 4 number of implants on each arch ;the number further increasing depending on the base material to be used.
- ACRYLIC HYBRID PROSTHESIS:
It is preferred for reducing cost option as it involves acrylic or composite teeth. However; acrylic teeth teeth are not as strong as ceramic with higher wear rates.
But; the positive aspect being if bone is very minimal/resorbed then in such cases this option makes the prosthesis lighter.
Approximate Cost – It would cost approx. 1.5L for both the arches.
Hence; in Conclusion; the choice of the material could vary depending on bone density and implant stability and is to be evaluated on an individual basis by the clinician.
