CEREC is a computerized crown manufacturing system. It can be used to make or replace a crown to restore an implant, but it is not capable of replacing the implant post in bone. Some dentists use the CEREC system to design and manufacture a customized abutment which attaches the crown to the implant body. Using CEREC to make a crown for an implant is no different than the process to restore a tooth. Both involve a scan of the supporting structure, in these cases prepared tooth or implant abutment, design of the crown and milling or the porcelain block. See the CEREC page on our website for more details.
A completed dental implant consists of the implant itself, an abutment which goes into the implant, and a crown on top of the abutment. It is possible to have a CEREC crown made in one visit, but anything more than that (such as a ceramic abutment), would probably take more time to get the best result.
Your question does not make sense. An implant is a titanium post that goes into the bone where you are missing a tooth. A crec crown does not replace an implant but can be made in one visit to attache to an implant that already has an abutment connected to it. (ie. the stump for to crown to cap onto.)
Cerec is a CAD/CAM technology that allows to take digital impressions in the office and produce the crown within 1-2 hours. It represents the all-ceramic materials for final crowns, inlays or onlays. If you would like to change the existing crown over implant or restore new implant with all-ceramic restoration the dentist will need to take impression of the implant with the contour of the gum tissue first. Then lab will fabricate all- ceramic abutment and the crown. Usually it takes 2-3 appointments in the best case in order to achieve the best esthetic result. Cerec machine is usually used for restorations of the teeth, not the implants.
There is nothing YOU can do. See a dentist to build up the tooth stump with composite core materials and make you a new temporary crown.
The art of dentistry and final restorations take a lot of experience, knowledge of teeth anatomy, feeling of harmony, balance, "feeling" of color, shape and symmetry. The problem that you describe is one of the most common details that identifies "good" crown from...
Really, no of this dental work ought to be coming loose. I understand that you are concerned that the one tooth is very short-it can be a factor. There is no good reason to "bridge" these teeth to anything else. You've done well with the photos you've enclosed. The main...
