These photos show the exposure & bonding of an Upper Right Central Incisor (UR1).
The UR1 had not erupted; a bracket was attached to the tooth. The first 2 photos show the UR1 a week or so post-op. The suture (blue) securing the end of the chain to the labial sulcus can be seen. The patient is wearing a removal appliance that has a prosthetic tooth (to fill the space of the UR1) together with 2 springs that help to create space to allow the UR1 to come down in to.
The rest of the photos show the UR1 slowly coming down into the space that has been created / maintained.
