Enhancement of Deficient Labial Bone Using Bone Ring Technique and Tent Pole Technique With Immediate Implant Placement

traditional guided bone regeneration will be done in which a flap will be raised under local anesthesia, followed by atraumatic extraction of the tooth, after which a 3D guided osteotomy will be done and the implant will be inserted, then covered buccally with autogenous bone graft chips and resorbable membrane before flap suturing

bone ring technique will be applied in which the same procedure as group A will be followed till tooth extraction, after which a trephine bure will be inserted through a 3D guide to prepare the site to receive the bone ring. The osteotomy will be done through the bone ring and the implant will be inserted to fix the implant in place, then covered buccally with autogenous bone graft chips and resorbable membrane before flap suturing.

tent pole technique will be applied in which the same procedure same as group A will be followed till implant insertion. Two monocortical screws will then be inserted using 3D guide, mesial and distal to the implant and extending 3 mm outside the bone, then covered buccally with autogenous bone graft chips and resorbable membrane before flap suturing.
