Soft Tissue Esthetic using Pink esthetic score with Autogenous Dentin Chips and Immediate Implantation versus Conventional Immediate Implantation with Xenograft in Thin Buccal Bone: (Randomized Controlled clinical trial)

Abstract Objective: When restoring teeth in the aesthetic zone, soft tissue aesthetics for an immediate implant is considered challenging. This study aimed to evaluate soft tissue aesthetics around immediate dental implants with dentin chips and xenograft in thin buccal bone. Methodology: 16 patients with non-restorable teeth were recruited in this study for immediate implant placement with augmentation. Patients were randomly assigned into two equal groups; dentin chips group with immediate implant and xenograft group with immediate implant also. Pink aesthetic scores are recorded on loading at 6 months & after 1 year of implant insertion according to Vanlıoğlu. Also, buccal bone and crestal bone resorption were measured using CBCT at 6 months & 1 year; implant stability was measured using osstel immediately on implant insertion & before loading, and pain is recorded as a Numerical rating scale according to Breivik. Results: In the present study, both groups showed better PES after 6 months and 1 year P-value = 0.343; P-value = 0.199 ; nearly same level of crestal bone & buccal bone at 6 months & 1 year P-value = 0.031; P-value = 0.029 P-value = 0.546; P-value = 0.268 ; implant stability is better at 6 months and one year P-value = 0.514; P-value = 0.340 and reduction in the post-operative pain within 1 week following implant placement with but with statistically significant difference within each group and also between both groups. Conclusions: The use of autogenous dentin chips proved to be a valid alternative to bone grafting materials to fill the jumping gap in conjunction with immediate implants in the aesthetic zone. PES, the overall difference between the control and the intervention groups showed no statistical significance.
