Purpose: The structural and compositional similarities between dentin and alveolar bone form the basis for utilizing dentin for bone regeneration. Various authors have recommended using treated mineralized, partially demineralized, or demineralized dentin grafts instead of xenografts because of their comparable clinical and radiographic results and lower costs. The current study therefore compared the effect of untreated mineralized dentin grafts (UMDGs) versus xenografts in vertical and horizontal augmentation around dental implants that were immediately placed in the mandibular anterior region. Materials and Methods: A total of 56 patients who required immediate dental implant placement in the mandibular anterior region were randomly allocated to group I (study), where ground dentin was washed with normal saline and placed around the dental implants, or group II (control), where a xenograft was used. The primary implant stability was measured at the time of implant placement. Secondary implant stability, plaque index (PI), bleeding index (BI), probing depth (PD), and keratinized mucosa width (KMW) were assessed at baseline (time of definitive abutment and provisional crown placement) and then at 3, 6, and 12 months. Pain and the number of analgesics consumed were assessed daily during the first postoperative week. Marginal bone loss (MBL) and radiodensity were assessed radiographically. Results: There were no significant differences between the groups in terms of postoperative pain, the number of analgesic tablets consumed, peri-implant mucositis, or peri-implantitis. Both groups showed comparable results for the PI, BI, and PD. Moreover, there was no statistical difference between the groups with regard to primary implant stability and secondary implant stability at baseline and 12 months. Group I showed significantly lower secondary implant stability after loading at 3 and 6 months and significantly greater bone loss and lower bone density before exposure. KMW and MBL after exposure were significantly higher in group I at all time points. Conclusions: Although UMDGs showed similar clinical results to xenografts, including primary and secondary implant stability, they had higher resorption rates than xenografts. Therefore, treatment of the dentin graft is required. Thus, the authors do not recommend using UMDGs. [ABSTRACT FROM AUTHOR] |
