Titanium Coping Fabricated with Laser Rapid Forming
To evaluate the feasibility of the laser rapid forming (LRF) technology for fabricating titanium coping, laser scanner was used to measure aluminium alloy die of abutment tooth and reconstruct its three-dimensional digital profile. The shape of coping was designed by computer based on the digital abutment tooth models. The processing parameters were established by employing orthogonal experimental design. Ten titanium copings were fabricated with LRF based on the coping data and the processing parameters, adhesive test of the titanium coping on the aluminium alloy die was made, and the fabricating precision of the LRF was evaluated through marginal adaptation test. Results showed that LRF technology could be used to fabricate titanium coping. Marginal adaptation test showed that the experimental data of gaps between fabricated copings were less than 120 μm which was accepted by clinical.
