The purpose of this present study is to compare alveolar bone changes and markers of gingival health around the new Lanes® dental implant which were rehabilitate using the new switch platform abutment ( SPR ) and the traditional ( CPK ) abutment.

Condition Intervention
Group A- 23 Implant Using Switch Platform -SPK Abutment. Group B- 22 Implant Using the Traditional -CPK Abutment. Procedure: spk Procedure: CPK Abutments

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic

Further study details as provided by Rambam Health Care Campus:

Primary Outcome Measures:
  • Soft tissue evaluation: [ Time Frame: 12 month ]
    Three month following abutment connection (approximately 2 months following cementation of the final crowns) baseline measurement will be taken. This will include probing pockets depth (PPD) and bleeding on probing (BOP) dichotomized in to 0 and 1 This measurement will be repeated at 12 month post surgery.

  • Radiographic evaluation: [ Time Frame: 12 month post surgery ]

    Bite wing radiographs will be used to assess changes in radiographic bone height.

    Baseline radiographs will be taking immediately following abutment connection and final radiographic evaluation will be taken 12 months post surgery.

Estimated Enrollment: 45
Study Start Date: September 2010
Estimated Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
