Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Periodontitis Dental Caries Alveolar Bone Losses Device: Calcium Phosphate, Calcium Sulphate Phase 3

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

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Single (Investigator)
Primary Purpose: Treatment
Official Title: Phase 3 Study of Using Combination of Bi Phasic Calcium Phosphate and Bu Phasic Calcium Sulphate During Extractions
Study Start Date : May 2012
Estimated Primary Completion Date : May 2013
Estimated Study Completion Date : May 2013

Arm Intervention/treatment
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

Primary Outcome Measures :
  1. 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 :
  1. 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.
