RESULT Statistical procedures All data were entered into a computer by giving coding system, proofed for entry errors Data obtained was compiled on a MS Office Excel Sheet (v 2019, Microsoft Redmond Campus, Redmond, Washington, United States). Data was subjected to statistical analysis using Statistical package for social sciences (SPSS v 26.0, IBM). Descriptive statistics like frequencies and percentage for categorical data, Mean & SD for numerical data has been depicted. Intra group comparison was done using paired t test (upto 2 observations) Comparison of frequencies of categories of variables with groups was done using chi square test. For all the statistical tests, p<0.05 was considered to be statistically significant, keeping α error at 5% and β error at 20%, thus giving a power to the study as 80%. * = statistically significant difference (p<0.05) ** = statistically highly significant difference (p<0.01) # = non significant difference (p>0.05) … for all tables Total ten patients were treated.Total n= 10 patient were included in this study. All patients had immediate implant placement and provisionalized . All implants shows 100 % survival rate after 6 month. Mean age (Mean + SD) group of patients treated was 24.7 + 8.27 years .

Total 10 patients included in present study with mean age group of 24.7(Table-1) Table -1 also reveals the male and female ratio which was 7:3 (7 male and 3 female). six patients had thick while four patients had thin biotype. (Table -1) The high survival rate of 100% found with present study which was similar to other studies.8,29 Implant survival rate with immediate loading was found to be 82-98% which was almost similar but slightly lower than the present study.39,41,42 Implant success rates have also been reported when single implant placed in healed sites were either immediately provisionalized8,40,43 or treated with delayed loading protocol, 44 showed success rate of 97 %. This suggest that when primary implant stability is achieved during surgery and the provisional restoration is adjusted to clear all centric and eccentric contacts ,immediate implant placement with socket shield is not a variable that affect implant success rate . Clinical probing depth is an important and reliable diagnostic parameter in continuous monitoring of both periodontal and peri implant tissue.45 Mean probing depth score of (highest probing depth score)obtained was 2.90 with SD of + 0.87 after 3 month (Table -3) and a mean probing depth of 2.90with SD of 0.87 obtained after 6 month (Table-3) that was similar to study done by Huynh –Ba et al 201640 and Baumer et al 2017.29 There was a very little change of reduced probing depth found after 6 month compared to 3 month.Mean highest probing depth score obtained was stable during follow up period. Independent t test showed a p value of 1.00 which was nonsignificant.(Table -3) Guy Huynh-Ba et al in 2015 found the probing depth ranging from 2.59-3.06 mm in immediately placed implants cases which was similar to the present study.40 Bleeding on probing found in present study was in 30% cases at 3 month (table-5) and in 20% cases at 6 month (Table-5) that shows a decrease in bleeding on probing on follow up. It shows absence of gingival inflammation. Similar results seen with Baumer et al 2017, Huy- nh et al 2016, Cosyn et al 2012.29,40,60 P value of 1.00 was obtained which was non significant. (Table- 5) There seemed to be no biological implant related complication which is especially important around the root segment with its periodontal ligament. By maintaining the ligament, also the amount of keratinized tissue width seemed to be maintained as the inserting dento gingival fibers were preserved. A mean plaque score obtained at 3 month in present study was 0.22 with SD of 0.11 (Table-4) and at 6 month 0.18 with SD of 0.08 (Table-4). Independent t-test shows p value of 0.412 which was nonsignificant. (Table-4) Although the influence of oral hygiene on implant success had been controversial.46,48 It is generally agree that plaque accumulation may induce a negative mucosal response.47 This indicate that good oral hygiene has been maintained around the implant . This essentially eliminates one variable that could potentially affect the peri implant gingival stability and tissue response in this study. In the current study, periapical radiograph were used to measure the interproximal bone at different time. An alternative could be cone beam CT; however, it was shown that CBCT correlates poorly with interproximal bone level than measured on periapical radiograph.49 Hardware and software of CBCT need to be improved especially in the presence of image distorting metallic implant which causes beam hardening effect. An important disadvantage of CBCT is the high dose exposure comparison with periapical radiograph.50 In present study the mean bone loss at 6 month found on mesial side was 0.24 + 0.20 (Table-2) while on distal side it was 0.25 + 0.17 (Table-2), similar to study done by Baumer et al in 2017.29 Study done by Mari Veltrio et al in 2015 found that single tooth implant shows a mean marginal bone loss of 0.96 mm and 0.83 mm on mesial and distal side which was quite higher than present study. 57 Mean marginal bone loss found in study on immediate implant placement and provisionalization by Kan et al 51 was 0.72 mm on mesial and 0.63mm on distal side which was similar to study done by Jose et al52 showed a mean interproximal bone loss of 0.83 ± 0.29 mm which was quite high than the present study . Botticelli et al53 in study of immediate implant placement and provisionalization found a mean marginal bone loss of 0.2 ± 0.7 mm in mesial and 0.5 ± 0.9mm distal side which was quite high. Bone loss on distal side was higher than the mesial side which was similar to present study. Less bone loss found in present study as in socket shield technique the part of root fragment was preserved which maintain the bundle bone .Remaining bundle bone prevent bone loss on buccal side .3 On titanium abutment without any later abutment manipulation helped to protect the initially forming blood clot and presented as a template for soft tissue contouring of already injured gingival.54 The presence of a glaze layer on the acrylic provisional improved soft tissue attachment and this may be due to smooth surface of restoration with low roughness that exhibit a least amount of bacterial adhesion.55 In delayed implant placement two stage surgeries are required. More marginal bone loss is expected during flap reflection or punching soft tissue which will deprive the already mineralizing bone from necessary blood supply .56 No second stage was required in present study as immediate implant placement is done. The esthetic outcome of the final restoration was evaluated at the 6-month followup visit using the PES/WES criteria previously defined by Belser et al. (2009). Mean PES obtained in present study was 13.40 + 0.39 while WES is 9.75 + 0.35 Highest score of PES was found with distal papilla,color and texture while lowest score found with alveolar process deficiency. Highest score for WES was found with texture and translucency while lowest score was found with volume and color.(Table-10) Highest frequency (PES) found in score 2 is for distal papilla, soft tissue color,soft tissue texture and in score 1 and 0 for alveolar process deficiency respectively given by examiner 1. Highest frequency (WES) found in score 2 is for tooth color,texture,translucency and characterization and in score 1 is for tooth volume respectively given by examiner 1.(Table-8) Highest frequency (PES) found in score 2 is for mesial papilla,distal papilla,height of gingival margin,soft tissue color and texture and in score 1 for alveolar process deficiency respectively given by examiner 2.Highest frequency (WES) found in score 2 is for tooth shape,tooth volume ,texture, translucency and characterization and in score 1is for tooth color respectively given by examiner 2.(Table-9) All patients included in the study reported the 100% clinical acceptability both for PES and WES score which is higher than the study done by Guy –Huynh-Ba et al.40 Tim De Rouck et al42 Mario –Ovetri et al, 57 Lai et al 58 and found a PES score of 10.9 for single tooth implant. Yin –Xin et al59 found a PES score of 7.58 and WES of 7.29 in single implant placement in anterior maxilla which was lower than the present study. Guy –Huynh-Ba et al40 found that a similar score of PES of 6.96 and WES of 6.07± 0.38 found with immediate implant and a PES OF 6.71 and WES of 6.44± 0.46 with early placed implant which was lower than the present study. Flip Raes in 2012 found a mean PES of 10.3 and WES of 7.11 with the implant placement done immediately, conventionally or grafted extracted sites which was lower than the present study .49 Cosyn et al found a PES of 11.67 and WES of 8.63 after 6 month in immediate implant placement and provisionalized site which was similar to present study.60 Preservation of bundle bone helps to preserve the bone height after implant placement. The present bone level help to maintain soft tissue level at buccal as well as interproximal area. All patients showed 100% satisfaction with smile, shape and position of teeth and color of gums. (Table- 32, 33) A high patient satisfaction was found in present study similar to study done by Guy –Huynh-Ba et al. 40 .
