title: Histological comparison of bone to implant contact in two types of dental implant surfaces: a single case study.
abstract: OBJECTIVE
  The purpose of this single case study was to evaluate the influence of different implant surfaces on human bone and osseointegration.
  
  
  METHODS
  A 47-year-old partially edentulous woman received two experimental implants along with conventional implant therapy. Experimental implants placed in the mandibular ramus consisted of machined and anodized surfaces, respectively. After three months of healing, the experimental implants were removed and prepared for ground sectioning and histological analysis.
  
  
  RESULTS
  The data demonstrate anodized implant surfaces present a higher percentage of osseointegration when compared to a machined surface in cortical human bone after a healing period of three months.
  
  
  CONCLUSIONS
  This single case study suggests an anodized implant surface results in a higher percentage of bone to implant contact when compared to machined surfaced implants when placed in dense bone tissue. However, further investigations should be conducted.
