title: Mandibular regeneration after immediate load dental implant in a periodontitis patient: A clinical and ultrastructural case report.
abstract: BACKGROUND
  In this case study, we characterized from radiographic, morphological and elemental point of view the mandibular reconstruction that occur in patients affects by periodontitis after application of endosseous titanium implants. In particular, we verified that the bone load applied by titanium implant was able to induce the mandibular osteogenic reconstruction.
  
  
  METHODS
  A 57-year-old female active smoker with no contraindications for dental implants and 3 unstable dental prostheses, underwent open surgery for the application of endosseous titanium implants (BANP IMPLANT S.R.L., Milan, MI, Italy) with Immediate load dental implant technique. At the time of presentation, patient was under treatment β- beta-adrenergic agents.
  
  
  METHODS
  Patient was affected by grade II periodontitis according to Armitage classification.
  
  
  METHODS
  Patient underwent open surgery for the application of endosseous titanium implants (BANP IMPLANT S.R.L., Milan, MI, Italy) with Immediate load dental implant technique. Implant placement was performed under local anesthesia after premedication with diazepam (0.2 mg/kg), given orally 30 minutes before surgery. After crestal incision, a meticulous cleaning of the oral cavity was carried out. We removed necrotic tissues and all inflammatory residues. Then, the bone cavity was extended gradually, according to the intended implant diameter. Inserted titanium implants were placed 8-12 mm subcrestally.
  
  
  RESULTS
  We demonstrated that the bone load applied by titanium implant was able to induce the mandibular osteogenic reconstruction in a periodontitis patient.
  
  
  CONCLUSIONS
  This case study can lay the foundation to improve understanding of the relationship between the immediate load dental implant and the mandibular regeneration.
