The efficacy of synthetic allograft and bioresorbable xenograft in immediate implant procedures: A comparative clinical study

Abstract

Aim: Immediate placement of an implant into the fresh extraction socket often leaves a space between the implant periphery and the surrounding bone, and the space between the implant and the bone is required to be filled with a biocompatible material such as a graft. This study aimed to compare the efficacy of synthetic bioactive glass allograft and dried freeze bovine bone grafts in the immediate implant site. Materials and Methods: The study comprised a total of thirty individuals in the age group between 16 and 60 years with at least one tooth indicated for extraction. The thirty participants were further divided into two groups. Group A comprised 15 participants who underwent extraction and buccal plate preservation (BPP), followed by immediate implant placement using synthetic allograft material (PerioGlas). Group B comprised 15 participants who underwent extraction and BPP, followed by immediate implant placement using xenograft as the graft material (Bio-Oss). The participants were evaluated both clinically and radiographically for 3 months, 6 months, and 1 year. The level of significance was set at P < 0.05. Results: PerioGlas and Bio-Oss in immediate implant site showed excellent osseointegration around the immediate implant site. However, the difference between the groups was not statistically significant. Conclusion: Both synthetic allograft and bioresorbable xenograft are promising and equally potential in bone formation around the immediate implant site.
