Dental bridges and superstructures, and methods for manufacturing thereof
The present disclosure provides a dental bridge intermediary structure comprising a superstructure ( 203 ) and a reference plate ( 200 ), with distance pins ( 202 ) connecting the two. A method for producing a dental bridge superstructure ( 203 ) is also provided.
1. A dental bridge intermediary structure for transfer onto a cutter, the dental bridge intermediary structure comprising:
a reference plate comprising a proximal side for arrangement on a sintering piston, and a distal side having a working surface;
distance pins extending distally from the working surface of the distal side of the reference plate and having distal ends located away from the working surface of the reference plate; and
a dental superstructure comprising a proximal side and a distal side, the distal side of the dental superstructure is provided with implant seats, and the proximal side of the dental superstructure is sintered onto the distal ends of the distance pins.
2. The dental bridge intermediary structure according to claim 1 , wherein the distance pins have a decreasing cross-sectional area in a proximodistal direction.
3. The dental bridge intermediary structure according to claim 2 , wherein the distance pins are conical.
4. The dental bridge intermediary structure according to claim 1 , wherein said dental bridge intermediary structure is a sintered dental bridge intermediary structure.
5. The dental bridge intermediary structure according to claim 1 , wherein said implant seats are milled.
6. The dental bridge intermediary structure according to claim 1 , wherein the distal side of the reference plate is provided with reference means.
7. The dental bridge intermediary structure according to claim 6 , wherein the reference means is protrusions extending away from the distal side of the reference plate.
