Alveolar bone resorption and labial bone plate reduction follow teeth extraction due to the deficiency of blood supply, derived from the loss of periodontal ligaments, and hence the socket shield technique with autogenous dentine was introduced to preserve the periodontal ligaments.
this study aim to evaluate of socket preservation using alloplast with socket shield versus Autogenous dentin graft with socket shield through radiographic analysis of alveolar bone dimension change and mean bone density in addition to histological and histomorphometric analysis for the quality of the formed bone.

|---|---|---|---|
| Study group (in one side) | Experimental | Modified socket shield technique with autogenous dentin graft |

| Control group (in contrlateral side) | Active Comparator | Modified socket shield technique with alloplast |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Modified socket shield technique with autogenous dentin graft material (in one side) | Procedure | The crown of the hopeless tooth will be decoronated, the root will then be sectioned, the lingual root fragment will be carefully retrieved, the remaining buccal root fragment will be thinned and concaved, The coronal part of this shield will be beveled to make a lingual slope then Tooth particles will be demineralized using 2% HNO3 (El-Gomhouria CO. Egypt) for 20 minutes to expose the dentin organic matrix. |
| Measure | Description | Time Frame |
|---|---|---|
| post opertaive edema | This will be assessed in the 1st week postoperatively and measured as follows: None (no inflammation) Mild (intraoral swelling confined to the surgical field) Moderate (extraoral swelling in the surgical zone) Severe (extraoral swelling spreading beyond the surgical zone). | after 7 days |
| change in pain score | it will be assessed using VAS It rates pain on a scale from 1-10, with 0 representing "no pain" and 10 "very much pain | 1 week and 3 months |
| Change in bone density | it will be assessed using CBCT | at baseline and 3 months |
| Change in bone height | it will be assessed using CBCT | at baseline and 3 months |
