Dimensional Changes of the Labial Alveolar Ridge After Socket Shield Technique With Computer Guided Root Sectioning

Not Applicable

• Conditions: Dental Trauma; Edentulous Alveolar Ridge
• Interventions: Procedure: Socket shield technique with computer guided sectioning of the root

• Registration Number: NCT05366985
• Lead Sponsor: Pharos University in Alexandria

Brief Summary

In this study, the dimensional changes of the labial alveolar ridge are digitally assessed after immediate implant placement using the socket shield technique with computer guided sectioning of the root.

Detailed Description

Ten hopeless teeth in the esthetic zone were included. A computer guide was used to section the root, leaving the coronal 2/3 of its labial part attached to the socket. An implant was then placed.

Preoperative and Postoperative (5 months later) intraoral scans were superimposed with a digital software to assess the dimensional changes of the labial alveolar ridge. Linear changes at 1,3 and 5 mm from the gingival margin and mean linear changes in a specified Area Of Interest (AOI) were measured.

Primary Outcome Measures

Name	Time	Method
dimensional changes of the labial alveolar ridge in orofacial direction in millimeters using GOM Inspect software	5 months	Linear changes at 1,3 and 5 mm from the gingival margin and mean linear changes in a specified Area Of Interest (AOI) were measured.
Thickness of the labial plate of bone in millimeters on the preoperative CBCT radiograph	Preoperative	On the preoperative CBCT scan, the thickness of the labial plate of bone was measured at the thickest part of its coronal third.The labial plate of bone was also checked for the presence of any radiographic coronal dehiscence and/or apical perforation by the root apex.
