SURGICAL PROCEDURE AND TEMPORARY RESTORATION
The teeth in the lower jaw were extracted and six implants were placed interforaminally
simultaneously in region 33-43. The patient received a metal-reinforced
denture as a temporary long-term solution. A Cercon bridge was fabricated for the
upper jaw at the same time. This gave the patient a satisfactory functional and
esthetic solution for the next few months.
PROSTHETIC AND LABORATORY PROCEDURE
Ankylos Balance posterior copings were selected for the six lower jaw implants.
They were ground first and then fitted with custom-fabricated Cercon abutments.
The Cercon abutments were cemented to the Balance copings in the laboratory
and a transfer template was fabricated as an index. A single-component Cercon
bridge with Galvano mesial construction was planned. Galvano caps were fabricated
for later cementing to the Cercon bridge to prevent tension within the Cercon
bridge combination and to achieve a passive seating.
In the next step wax provisional of the lower jaw bridge over the Galvano caps was
fabricated. They were veneered with Cercogold spacer (DeguDent, Hanau/Germany)
beforehand to simulate the cement gap. The Cercon bridge was waxed up, scanned,
milled and sintered in the classical Cercon process and then fitted over the Galvano
caps and veneered. The Galvano caps were cemented in the mouth with the
finished Cercon bridge and plugged on the copings because of the accurate friction fit.
