Vianna TT, et al. - In patients with a history of chronic periodontitis, rehabilitated using Tissue Level or Bone Level implants, researchers evaluated the clinical and radiographic characteristics in peri-implant marginal tissues. Findings suggested likewise performance of both approaches regarding clinical and radiographic parameters for rehabilitation of patients with a history of chronic periodontitis under a rigid supportive therapy. Findings suggested no statistically significant difference in clinical and radiographic peri-implant evaluation between groups at all assessment periods.
