Application of Nano-Hydroxyapatite Implantation for Periodontitis Treatment and Oral Tissue Regeneration

Abstract

In this study, the combined application of nano-hydroxyapatite (nHA) implants and root planing was used for the treatment of periodontitis. A total of 80 patients with chronic periodontitis who were admitted to our hospital from January 2020 to March 2023 were selected and randomly divided into the control group (root planing) and observation group (root planing+nHA implants), each consisting of 40 cases. The gingival crevicular fluid samples were collected to detect changes in inflammatory factors before, 6 weeks after, and 12 weeks after operation. Additionally, periodontal indexes such as plaque index (PLI), sulcus bleeding index (SBI), probing depth (PD), and attachment loss (AL) were evaluated. The therapeutic efficacy, aesthetic outcome, and incidence of adverse reactions were analyzed between the two groups. The results indicated that after the operation, both groups exhibited lower levels of periodontal index AL, PD, SBI, PLI, and inflammatory factors compared to pre-operation levels. However, the observation group demonstrated superior outcomes with significantly higher postoperative PES scores and total treatment effective rates. Although adverse reaction incidence was slightly lower in the observation group (7.5%) than in the control group (15%), there was no statistically significant difference between them (P > 0.05). Therefore, it can be inferred that the combined application of nHA implants and root planing in patients with chronic periodontitis yields favorable postoperative recovery and effectively enhances the periodontal condition. Consequently, this approach can serve as an optimal therapeutic strategy for the treatment of chronic periodontitis.
