简要总结
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.
详细描述
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.

结局指标
主要结局
dimensional changes of the labial alveolar ridge in orofacial direction in millimeters using GOM Inspect software
时间窗: 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
时间窗: 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.
