Interventions
Socket Shield Technique:After tooth decoronation, the remaining root was reduced to approximately 1 mm above the alveolar crest using a diamond bur. The planned implant position was marked within the
Immediate Implant Placement:A minimally invasive, flapless tooth extraction was performed. The extraction socket was thoroughly debrided and irrigated with sterile saline. The integrity of the buccal
