The osteogenic effect of 3D-printed bone grafting guides in PAOO: a retrospective cohort study.

ABSTRACT:

Background

Periodontally accelerated osteogenic orthodontics (PAOO) effectively increases alveolar bone volume and broadens orthodontic treatment options. However, bone grafting during PAOO faces challenges such as graft displacement, membrane collapse, and insufficient coronal bone regeneration. This study aimed to evaluate whether 3D-printed digital bone grafting guides could improve graft stability and alveolar bone regeneration compared with conventional PAOO.

Methods

In this retrospective cohort study, 10 patients who underwent PAOO surgery were evaluated. Patients were divided equally into GBG (digital guided bone grafting) and Control groups (conventional PAOO). Cone-beam computed tomography (CBCT) images and periodontal clinical parameters, including probing depth (P
