Abstract
The purpose of this pilot randomized controlled trial was to analyze and compare the effects of advanced platelet-rich fibrin (A-PRF) and plasma rich in growth factors (PRGF) combined with deproteinized bovine bone mineral (DBBM) on bone regeneration outcomes in maxillary sinus augmentation (MSA) procedures. A total of 15 patients in need of MSA were consecutively recruited. Maxillary sinuses were grafted with DBBM alone (control group), DBBM mixed with A-PRF (PRF group), or DBBM mixed with PRGF (PRGF group). After a 6-month healing period, bone core biopsy samples were collected prior to implant placement for histologic and histomorphometric analyses. The mean percentage of mineralized tissue (MT) was 20.33 ± 11.50 in the control group, 32.20 ± 7.29 for the PRF group, and 34.80 ± 6.83 for the PRGF group, with no statistically significant differences across the three groups (P > .05). The mean percentage of remaining bone grafting material (RBGM) was 24.00 ± 7.94 for the control group, 26.00 ± 7.78 for the PRF group, and 15.80 ± 8.23 for the PRGF group, with no statistically significant differences across the three groups (P > .05). Finally, the mean percentage of nonmineralized tissue (NMT) was 55.66 ± 7.77 for the control group, 41.40 ± 8.32 for the PRF group, and 49.60 ± 5.68 for the PRGF group, with no statistically signifcant differences across the three groups (P > .05). These findings suggest that the addition of A-PRF and PRGF to DBBM does not enhance new bone formation outcomes in maxillary sinus augmentation procedures. Neither of the two platelet concentrates were superior to the other in any of the variables assessed.
期刊介绍:
The International Journal of Periodontics & Restorative Dentistry will
publish manuscripts concerned with all aspects of clinical periodontology,
restorative dentistry, and implantology. This includes pertinent research
as well as clinical methodology (their interdependence and relationship
should be addressed where applicable); proceedings of relevant symposia
or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published
or submitted for publication elsewhere.
