Objective:
Current study evaluated whether use of the platelet-rich powder (PRPP), piezosurgery device and diode laser after removal of jawbones cysts and benign bone formations and extraction of impacted tooth could enhance bone regeneration before dental implantation.
Methods:
A study was conducted among 200 patients with post-surgical cavities (not exceeding 1.5 cm upon cystectomy, benign bone tumor removal and impacted tooth extraction) who underwent plasma powder, autograft, allograft, xenograft or beta-tricalcium phosphate augmentation procedures.
Results:
PRPP implantation in combination with irradiation of bone cavity by diode laser led to the formation of 15.40 % ± 2.1 of new bone. The activity of reparative osteogenesis on the bone surface was BB = 6.71 ± 1.3, which is 3 and 3.5 times higher than the mean value in comparison group after augmentation of xenograft and beta-tricalcium phosphate. The value of bone tissue resorption for main group patients was less pronounced (Ra.Oc = 25.20 % ± 2.1). The ratio between pro- and anti-inflammatory cytokines in the main group after 1, 7 and 30 days since surgical procedure was lower than the ratio of the corresponding cytokines in the comparison groups.
Conclusion:
The examination of computed tomograms, histological and morphometric analysis of bone tissue after trepanobiopsy, cytological analysis of swabs and enzyme immunoassay to determine local immunity indicated that the proposed method of treatment with the use of PRPP, the piezosurgery device and the diode laser has a positive effect: it helped to optimize reparative osteogenesis after filling post-surgical cavities and restore bone volume.
