A the implants. The average recession at

A retrospective clinical study on 10 successive patients estimated volumetric changes of the affected facial structures and its esthetic outcome. Concurrent to the animal studies the implants healed without adverse effects and clinical manifestation of peri-implant tissues showed healthy site with the mean tissue loss on the facial side of 0.21 ± 0.18 mm, mean loss of the marginal bone level at the implant shoulder was 0.33 ± 0.43 mm at the mesial aspect and 0.17 ± 0.36 mm at the distal aspect of the implants. The average recession at implant area was 0.33 ± 0.23 mm and at adjoining teeth was 0.38 ± 0.27 mm in addition to a mean pink esthetic score of 12 was recorded from photographs (Bäumer 2017). Volumetric changes were demonstrated by socket shield technique in different clinical reports. While comparing, the maximum loss of 1.67mm in labial direction was seen in a study by Bäumer et al 2013 to maximum horizontal loss of 0.72mm was noted by Chen and Pan in 2013. Different subject, measurement method and tooth position were recognized as the reason for this dissimilarity.
