<br/><br/> The loss of a tooth triggers a remodeling reaction as part of the healing process, involving various degrees of alveolar bone resorption, especially affecting the buccal lamella. The bundle bone is primarily vascularized by the periodontal membrane of the tooth. Therefore, this part of the alveolar bone is compromised by the extraction, to such an extent that the buccal lamella is insufficiently nourished, leading to its total or partial resorption.,A substantial 0.5% to 1% of the alveolar ridge volume is lost as the result of it. The socket-shield (SS) technique provides a promising treatment adjunct to better manage these risks and preserve the post-extraction tissues in aesthetically challenging cases. This technique was first described in 2010 which aims at leaving the buccal fragment of root intact and placing implant on the lingual aspect of that fragment so that the tissues which remain in contact with the buccal fragment retain their vitality and prevent the ridge from collapsing thus improving the aesthetics especially during implant in the anterior maxillary region.The tooth root fragments periodontal attachment apparatus (periodontal ligament, attachment fibers, vascularization, root cementum, bundle bone, alveolar bone) is intended to remain vital and undamaged so as to prevent the expected post-extraction socket remodeling and to support the buccal tissues. Aim: The aim of the study was to compare Clinical and Radiographic assessment of Grafted Esthetic zone Socket shield technique vs.Graftless Esthetic zone Socket shield, with immediate implant Placement & immediate temporization
