Abstract
Aim: This study was done to evaluate patient satisfaction and early implant failure of computer guided versus free hand immediate implant placement in fresh extraction sockets in esthetic zone. Methodology: The sample of this study consisted of twenty patients randomly selected from outpatient clinic of prosthodontics, Endodontic and Oral Surgery departments, faculty of dentistry, Cairo University. All patients were with teeth or remaining roots in the aesthetic zone (from right second premolar to left second premolar) and indicated for extraction and replacement with immediate implant. Preoperative CBCT was taken to ensure the presence of at least 3 mm of bone apical to root apex of the tooth to be extracted and the presence of sufficient labial bone to avoid labial plate fracture during extraction.For the test group, (computer guided group) the Preoperative CBCT was used for dental implants planning and formation of the surgical stent while for the control group (free hand group) it was used for implants size selection based on the specific tooth being replaced
