Patient needs restorative work on old implant: identify?

An internal connection like that is probably a zimmer product (corevent) or a system that uses an internal hex similar to the zimmer. Remove the restoration and look at the connection type. You can also use the website " what implant is that" to help.

Looks similar to a Camlog implant.

Need radiograph showing the apical to ID this properly

" The patient wanted to know about the restorative work done on the implant(s)" From what I can see on the radiograph, the work looks very good...…. it seems like a cementable bridge, which can be tapped off. The bridge can be modified once it is off..... and if the abutments are well seated and are solid, there is really no concern about the type of implants that were used.....

Those are Zimmer Screwvent implants or a clone (internal hex connection ). The screw access in these anterior cases usually is not in the cingulum area. The implant on the left shows bone loss. Is the "restorative work" for esthetic reasons?

Bone loss down to the first thread was considered somewhat normal on those old implants before platform switching. I would not necessarily say that is a problem without further information. As suggested earlier, the site " what implant is that " is excellent.

I hope the individual that described "bone loss" is as critical of his own work. I am not even sure that is to the first thread. That appears to be a Zimmer TSV or at least a clone.

It`s Tapered Screw-Vent Implant Provided by Zimmer Dental co. Probably, 4.5mm Diameter Platform.
