A histological study of non-ceramic hydroxyapatite as a bone graft substitute material in the vertical bone augmentation of the posterior mandible using an interpositional inlay technique: A split mouth evaluation

摘要: The aim of this study was to compare the influence graft material (non-ceramic hydroxyapatite versus autologous bone) on bone behaviour and perform a resonance frequency analysis implants placed in augmented sites evaluate stability. For study, 11 patients with bilateral edentulous areas mandibular posterior region were selected. Alveolar augmentation osteotomies bilaterally (split mouth design) performed. In one hemiarch, space generated by osteotomy grafted an interpositional intra-oral (control group). other non-ceramic (ncHA) (test groups randomized. After 6 months healing, sample retrieved from each side for histological evaluation using trephine drill that 2-mm internal diameter. implant stability quotient (ISQ) measured immediately following placement at baseline after follow-up. Good incorporation observed both groups; however, test group, residual-grafted observed. Bone density marrow spaces similar between groups. Correlations ISQ values histometric variables not (p>0.05). results trial suggest ncHA may be elected as grafting materials vertically augment atrophic mandibles.
