An implant is usually the standard of care. When a permanent bridge is made the teeth that support the bridge have to be prepared with the drill and all of the enamel is stripped off of the teeth. A single tooth implant is difficult to place in the central incisor area and a bone and tissue graft is normally needed. You need to have and implant specialist, I would suggest a periodontist and orthodontist evaluate your situation prior to any decisions.
The three unit bridge in your mouth will not prevent you from orthodontics. From the look of you photos orthodontics is the way to go. I your bite is not correct then the laminates will fail and break. Please seek another opinon.
Yes. Without an examination it is impossible to guarantee a correct answer, but from you description it sounds like you have advanced gum disease and require full dentures or something supported on implants.
When an implant crown retaining screw fractures it is of concern. All of the newer style implants are designed to keep stress to a minimum on the screw. If the screw has broken twice I would have the dentist take a close look and the bite. The bite might look good but when you move your jaw from side to side the tooth might me hitting or interfering. If the implant is an older style external hex design then it is a design problem and you might always have broken screw issues unless the implant is replaced with a newer style.
Most of the time teeth need to be extracted as a result of external resorption. Orthodontics is an option if a crowded condition exists. You have to be careful because you could end up with a space or not enough gum tissue in between the teeth that will result in a black space. Ask the orthodontist about the possibility of this. The alternative is an implant to replace the tooth or a permanent fixed bridge.
