Hyaluronic Acid Gel in Ridge Preservation

Study Overview
=================
Brief Summary
-----------------
hyaluronic acid gel applied at the extraction socket after extraction immediately to preserve the socket from post extraction resorption. hyaluronic acid has ability for osteogenesis and new bone formation.

Detailed Description
-----------------
twenty-four patients with one hopeless tooth at least, first CBCt before extraction to evaluate the dimension of the socket, then atraumatic extraction of the tooth to preserve the bony wall of the socket, after extraction and curettage the socket applied hyaluronic acid gel inside the socket and applied collagen membrane to secure the socket. After 4 months of extraction, CBCt was done to evaluate the dimension of the socket and the effect of hyaluronic acid. Furthermore, The core biopsy was taken by trephine bur at the time of implant placement for evaluate the histological appearance of the bone to evaluate the secondary outcome. then after three months the crown was delivered as a prosthetic part.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| clinical outcome | measurement clinical bone width of the socket by millimeter before and 4 months after extraction ... | baseline(before extraction)/ four months later after extraction | 
| Radiographic measurement | Radiographic measurement of bone width by CBCt before and 4 months after extraction | baseline(before extraction)/ four months later after extraction | 
| Radiographic measurement | Radiographic measurement of bone height by CBCt before and 4 months after extraction. | baseline (before extraction)/ four months later after extraction | 

Secondary Outcome Measures
