Brief 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.

Eligibility criteria: Inclusion Criteria:

1.A healthy medical condition (ASA 1 and ASA 2 according to the American Society of Anesthesiologists classification) 2.The ability to withstand the stress of dental implant surgery 3.The need for bilateral implant-supported rehabilitation in the mandibular premolar/molar area.

-

7. Drug users (anti-inflammatory agents, bisphosphonates)
