The study was designed to assess the effectiveness of conservation ridge preservation (horizontal and vertical dimension) after tooth extraction with and without combination of bone substitutes based on synthetic (calcium sulfate mixed with phosphate.

Further study details as provided by Rambam Health Care Campus:

Primary Outcome Measures:
  • The change of the dimension of the alveolar ridge [ Time Frame: Immediatly after tooth extraction (up to 10 minutes after the extraction) and 4 monthes after extraction ]

    Measurement of socket width (aspect B/L) at three points Height:

    1. Record-high ridge (buccal/lingual-palatal )
    2. 3 mm apically to the peak ridge (buccal/lingual-palatal )
    3. 6mm apically to the peak ridge (buccal/lingual-palatal )

    Measurement of alveolar ridge height:

    Measured distance between the summit crater and the peak of the ridge and the center line connecting the CEJ of adjacent teeth

Secondary Outcome Measures:
  • Post operative adverse effects [ Time Frame: immediate after the extraction and until 4 monthes after ]
    The investigators will record the optionally adverse effect such as edema, infection, pain, exposure of the membrane.

Estimated Enrollment: 40
Study Start Date: May 2012
Estimated Study Completion Date: May 2013
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Alveolar ridge dimensions
Control group - Only extraction teeth
Experimental: Alverolar ridge dimension
Extraction of teeth and implant a bone substitute
Device: Calcium Phosphate, Calcium Sulphate
1cc of Calcium Phosphate and 1cc of Calcium Sulphate

Detailed Description:
Using the combination of these two bone substitute is taken in order to diminish the alveolar ridge alternations after tooth extraction. the investigator will measure the horizontal and vertical changes (primary outcome) and the adverse effects (secondary outcome)in 4 months period
