Guided Root Slice Replantation vs. Socket Shielding for Immediate Implant Placement in Esthetic Zone

The goal of this clinical trial is to learn whether two different tooth-preservation techniques work equally well when placing a dental implant right after a tooth is removed in the front of the mouth (the "esthetic zone"). It will also learn whether using artificial intelligence (AI) to help plan the surgery improves the results. The main questions it aims to answer are: * Does keeping part of the root in place using a technique called autogenous root slice replantation work as well as a similar technique called socket shielding, in terms of appearance and gum health around the implant? * Does AI-guided surgical planning improve accuracy, appearance, and gum health compared with traditional planning? Researchers will compare participants who receive autogenous root slice replantation to participants who receive the socket-shield technique to see if one produces better outcomes than the other. Both groups will have their implants placed using a 3D-printed surgical guide made from AI-assisted digital planning. Participants will: * Have a tooth removed and an implant placed on the same day, using one of the two techniques * Have their surgery guided by a custom surgical guide, planned with AI assistance * Return for follow-up visits so researchers can check healing, gum appearance, and how well the implant fits with their smile
