Extraction of teeth results in subsequent alteration in the alveolar ridge contour. This may ultimately lead to failure in future prosthesis especially having an influence on the anaesthetic zones. To overcome this problem procedures like atraumatic extraction, bone and soft tissue grafting, ridge augmentation, immediate implants were implemented. However, all these techniques failed to show the complete preservation of alveolar socket particularly in the facial aspect. Clinical studies have proposed a method of retention of root either of vital or non-vital teeth compensating for the variations that caused following tooth extraction. In addition, histological studies showed newly formed bone and cementum around the retained root fragment and implant giving it a favourable result for the Socket shield technique as the best treatment option, hence maintaining the facial gingival form.
