Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Linear vertical bone height at surgery day and after 4 months calibrated periodontal probe will be used to measure the distance from the stent fixed reference holes to the alveolar crest at 4 specific points mid buccal mid lingual Mesial distal of the socket. ,Linear horizontal bone height at surgery day and after 4 months 3 fixed horizontal holes in the stent (1 mm,3mm,5mm) on buccal and lingual sides will be measured by graded probe,Bone density at surgery day and after 4 months percent of newly formed bone as seen in histologic sections.,Keratinized Tissue Width at 4th month re-entry distance in mm between gingival margin to the mucoginigival junction using the roll test | — |
Secondary
| Measure | Time frame |
|---|---|
| soft tissue healing 3rd and 7th post-extraction days Landry's healing scale,Soft Tissue Augmentation 4 months during re-entry surgery difference in mm between stent-to-bone distance and the stent-to-mucosa distance by graded probe,Adverse Events during the whole study period nature and severity of any harms will be reported as present or absent. | — |
