Comparative histological results of different biomaterials used in sinus augmentation procedures: a human study at 6 months

Abstract

Longer term histological and histomorphometric studies will be necessary to understand better the resorption times of all these biomaterials. The high interconnecting microporosity allowed, in all the present biomaterials, the ingrowth of newly formed bone and vessels in the pores of the partially resorbed particles. In conclusion, within the limitations of the present study, the data provided support the fact that all these biomaterials can be used, successfully, in sinus augmentation procedures.

Tissue reactions after simultaneous alveolar ridge augmentation with biphasic calcium phosphate and implant insertion—histological and immunohistochemical evaluation in humans

“…To our knowledge, this study is the first approach presenting immunohistochemical findings from human biopsies retrieved after BCP application, as other studies performed on humans used undecalcified sections for histological evaluation of BCP healing [8,19,20]. Our histological results of BCP granule incorporation upon augmentation procedure are similar to findings from other histological investigations on decalcified specimens in humans and animals [16,18].…”

Study of in vitro degradation of cellulose acetate membranes modified and incorporated with tetracycline for use as an adjuvant in periodontal reconstitution

“…Bone regeneration crucially depends on the number of progenitor cells in the target region (Iezzi et al, 2012).…”

Bilateral sinus floor augmentation using 100% alloplastic biomaterial for later rehabilitation of atrophic maxilla. A 5-year tomographic follow-up

“…It has been compared to biphasic calcium phosphate by previous studies which concluded that both types of biomaterial are adequate to be used in sinus lift procedures. 27,28 The 60-day waiting period before transmucosal abutments were placed was necessary because the implants used for the case reported herein were launched into the market with promises of speeding up bone repair and reducing the waiting period for load to be applied. This fact is justified by the hydrophilic features of implants responsible for providing greater wettability and, as a result, stronger interaction between implant surface and the biological environment.…”
