title: The Comparison of Porous Titanium Granule and Xenograft in the Surgical Treatment of Peri-Implantitis: A Prospective Clinical Study.
abstract: BACKGROUND
  Regarding the current approach, there is no evidence to show which treatment technique is the most accurate and useful in peri-implant defects.
  
  
  OBJECTIVE
  The aim of this study is comparing the effect of porous titanium granule (PTG) with rotary titanium brush and the use of xenograft and collagen membrane in the treatment of intra-bony peri-implant defects.
  
  
  METHODS
  Twenty-two patients, suffering peri-implantitis defects were included this study. Patients were divided into two groups: The PTG group used rotary titanium brush, PTG, and platelet rich fibrin (PRF) membrane. The XGF group used xenograft bone substitute, collagen membrane, and PRF membrane. Clinical measurements and cone beam computed tomography per region were recorded as baseline and sixth month after surgery.
  
  
  RESULTS
  The mean CAL values were improved from 5.29 ± 1.06 to 3.59 ± 0.88 mm in PTG group, while in XGF group; these values were improved from 4.77 ± 1.05 to 3.30 ± 0.58 mm. Radiographic bone filling values displayed a statistically significant difference between of groups. In PTG groups, these radiological values increased more than the XGF group.
  
  
  CONCLUSIONS
  PTG may be more appropriate for peri-implantitis surgery than xenograft due to inert structure and comfortable use of PTG to provide mechanical support for enlarging the surface area of the implant.
