Comparative evaluation of osseous bone splitting by piezosurgery and intramarrow penetration in localized intra-bony defects in patients with chronic periodontitis: a clinico-radiographical pilot study

Chronic periodontitis leads to intrabony defects that compromise tooth stability. Conventional treatments often show limited bone regeneration. Techniques like bone splitting by piezosurgery and intra marrow penetration (IMP) have emerged to enhance bone healing. This study aimed to explore their comparative effectiveness in promoting osseous regeneration and improving clinical outcomes in affected patients. 16 patients with probing depth ≥6 mm were selected and randomly underwent open flap debridement (OFD), followed by osseous bone splitting of the defect using piezosurgery (group A) and IMP (group B), with subsequent bone graft placement in the defect. Full mouth gingival index, plaque index, pocket probing depth and relative attachment level were assessed at baseline and 6 month visits. Defect base level (DBL), crestal bone level (CBL), intrabony defect depth (INTRA) and defect angle (ANG) were also analysed. Intragroup comparison shows statistically significant results in all clinical and radiological parameters in group A and group B (p<0.05). Intergroup comparison shows similar results in both the groups at 6 months interval. Both techniques of bone splitting using piezosurgery and IMP have shown promising results in the management of localized intra-bony defects in patients with chronic periodontitis.
