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

Effect of Two Incision Techniques on Soft and Hard Tissue Outcomes in Immediate Implant Placement in Class II Extraction Sockets of the Esthetic Zone:

This randomized controlled clinical trial investigates the effect of two different surgical approaches-Vestibular Socket Therapy (VST) and Flap Elevation Technique-on soft and hard tissue outcomes during immediate implant placement in Class II extraction sockets of the anterior maxilla (esthetic zone). The study enrolled 26 systemically healthy adult patients contributing a total of 48 surgical sites. Each site was randomly assigned to one of the two treatment groups. The VST group employed a minimally invasive vestibular incision to allow atraumatic extraction, implant placement, bone grafting, and membrane placement while preserving the labial soft tissue and periosteal blood supply. The Flap Elevation group followed a conventional intrasulcular flap approach. In both groups, implants were placed with 30 Ncm torque and augmented with MegaOss™ allograft and a resorbable collagen membrane (T-barrier™). Clinical and radiographic evaluations were conducted at baseline, 6 months, and 12 months post-loading. Outcomes measured included Pink Esthetic Score (PES), peri-implant probing depth (PD), mucosal level changes, and crestal bone level changes.
