A comparative study of alveolar bone changes after immediate implant placement with and without bone graft material in the buccal gap around the immediate implant: A review article

The aim of this review study was to evaluate the results and effects of employing or not using bone graft materials in the buccal gap around the immediate implant, on the alveolar bone dimensions and the success of the implant and its complications after immediate implant placement.

This study was conducted using electronic versions of articles in Pupmed and Google Scholar from 2010 to 20/4/2022. The extracted electronic articles include 14 randomized clinical trial studies, a high number case report and two systematic reviews based on clinical trial. All the researches are human clinical studies . Articles written in English and Persian, as well as laboratory and animal studies and the use of collagen membranes during immediate implant placement, have been excluded from the study. The age of patients is over 18 years and the duration of evaluation is four months and more. Finally, 17 articles were reviewed.

The effect of using or not using Bone Graft in buccal gap on implant failure cannot be confirmed. It does not seem to have a significant effect on reducing the horizontal and vertical dimension of the buccal plate and has a moderate effect on the beauty of the soft tissue around the implant and the amount of mid-buccal gingival mucosa dimension and reducing the horizontal and vertical dimension of the buccal plate. With the use of bone powder, minor surgical complications such as pain are slightly increased.
