Evaluation Of The Effect Of Surface Properties On The Stabılıty Of The Different Implants
Condition: Dental Implantation
Study type: Interventional

Summary: 
      This randomised clinical study aims to evaluate different surfaced implants (alkali-modified
      surfaced implants or sand-blasted surfaced implants) stability with resonance frequency
      analysis(RFA).
    

Detailed description: 
      This is randomised controlled double blind study. Fourteen patients (8 women and 6 men;age
      43.7 ± 8.56 years) who were attending the Oral and Maxillofacial Surgery Department and
      scheduled for implant placement surgery were included in this study. Dental implants were
      placed using one-stage protocol. After adminstration of local anesthesia (Ultracain DS;
      Aventis Pharmaceuticals, Istanbul, Turkey ), an incision was made on the alveolar ridge. A
      total of 50 implants (Impladent implants from the Lasak) were placed in the not site
      assignement mandibular premolar/molar sites according to the manufacturer's instructions. To
      prevent bias which implant to the right or left to make the decision investigators decided by
      envelope. The person making the measurement does not know which surface implant is made to
      the patient. An equal number of implants were applied simultaneously with different surfaces.
      The patient does not know where the implant is placed. All used implants were 3.7 width,
      10mm. height and same design for standardization this study. Investigators obtained good
      primarly stability and placed a healing cap for 45 implants . 3 sandblasted and acid-and
      alkali-treated surface straight (bioactive)implants and 2 sandblasted surface straight
      implants were excluded in this study for bad primary stability. Investigators used to measure
      implant stability with Osstell ISQ ( Integration diagnostic AB, Savedalen, Sweden) for each
      implant at the time of surgery before flap closure, 2. week,6. week and 12. week
      postoperatively.This device was used in both buccolingual and mesiodistal direction. The
      Smartpegs (Integration Diagnostics AB, Göteborg, Sweden) were compressed and the measurements
      were performed by the same surgeon for standardization of the stability measurements. The
      measurements were taken twice in the buccolingual direction and twice in the mesiodistal
      direction. The arithmetic mean of the 2 measurements from each direction was regarded as the
      representative ISQ of that implant. In addition, each implant was clinically evaluated at all
      visits for mobility, pain, and signs of infection.
