Implant Placement in the Preserved Socket Using Socket Shield Technique With Autogenous Dentin Graft Versus Preserved Socket Using Socket Shield With Alloplast

The crown of the hopeless tooth will be decoronated with a chamfer diamond bur and a large-head round diamond bur under copious irrigation, until the bone crest level. The root will then be sectioned along the long axis into buccal and palatal halves with a long shank fissure bur. The lingual root fragment will be carefully retrieved using microperiotome. The remaining buccal root fragment will be thinned and concaved slightly with a long shank fissure bur. The thickness of the buccal root fragment should be at least 1.5 mm to ensure resistance to fracture and resorption. The coronal part of this shield will be beveled to make a lingual slope for a better emergence profile with a large head round diamond bur. The socket shield will be checked for immobility so the implant could be inserted palatally into the socket shield. After the final preparation of the socket shield, Graft will be placed using autogenous dentin graft from the discarded palatal part of the tooth
