Management of jump space in immediate implants with and without demineralised freeze dried bone allograft: a randomised controlled trial

Purpose: The present study aimed to evaluate and compare the management of Jump space (JS) in immediate implants with and without Demineralised freeze-dried bone allograft (DFDBA) with flapless approach. Materials and Methods: The present study included 40 sites with immediate implant placement in the maxillary anterior region. Group 1 patients were treated without augmentation while Group 2 patients with DFDBA in the JS. Both the groups were further subdivided according to the horizontal dimensions as JS less (G1S1, G2S1) or more than 2mm (G1S2, G2S2). Plaque index (PI), Gingival Index (GI), Probing depth (PD), Testori esthetic score (TS), VAS score, Crestal Bone height (CBH), Ridge width (RW), Vertical distance (VD) and radiolucent area (RA) were evaluated radiographically with CBCT at baseline and 12 months’ post therapy. Results: Significant differences were observed in CBH in the midfacial region in G1S1- G2S1 with the mean of 0.34±0.19mm and G1S2 –G2S2 with 0.75±0.26 mm at 12 months. Significant differences in TS were observed in G1S1 and G2S1 with mean value of 0.55±0.53 while G1S2 and G2S2 exhibited value of 1.33±0.82. Conclusion: DFDBA shows better CBH preservation in midfacial region, reduction in RA indicating greater resolution of JS thereby leading to better hard and soft tissue healing.
