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

Abstract Objectives: soft tissue in the esthetic zone 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. Materials and Methods:non-restorable teeth (n=16) were recruited in this study for immediate implant placement with augmentation using dentin chips and xenografts. Patients were randomly assigned into two equal groups (n=8). Pink aesthetic scores are recorded on loading, at 6 months & after 1 year of implant insertion according to Vanlıoğlu. ; buccal, crestal bone resorption was measured using CBCT at months & 1 year and implant stability was measured using osstel twice, and pain was recorded according to Breivik. Results: Both groups showed better PES after 6 months and 1 year P-value = 0.343; P-value = 0.199; the nearly same level of crestal bone & The buccal bone at 6 months & 1 year; 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 but with statistically a significant difference 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. Clinical relevance : Autogenous dentin chips may be a good alternative to xenograft with a cost-effectiveness advantage
