For implant operation, total management of patients was performed by the dentist, dental technician, and dental hygienist in terms of the operation, the fabrication of prosthetic appliances, and post-operative care. Thus dental technicians are included in our discussion from the stage of treatment planning before the operation. As part of this process, two super structures, overdenture (case 1) and bone-anchored full bridge (case 2) were compared.
Integral® Implant (Calcitek Inc., U.S.A.), 3.25 mm in diameter and 8 mm or 10 mm long, and prosthetic materials made by Calcitek Inc. were used in those cases, and the overdenture was made of heat-cure resin (Acron, GC Co., Japan) and artificial teeth (ENDURA, Shofu Co., Japan).
Type IV gold alloy (Panahellaus Inc., Germany) was used for a bone-anchored full bridge.
The results were as follows:
The patients in both cases were satisfied with their prosthetic appliance over the implant, as compared with the conventional denture they used before operation.
It took 50 days in case 1 and 34 days in case 2 to complete the prosthesis.
There was no difference in difficulty of the fabricating process between overdenture and conventional one. The bone-anchored full bridge in case 2, however, costed much more because of its materials for transfercoping than the overdenture in case 1. Consequently, the cost of case 2 was more than three times greater than that of case 1.
