简要总结
Patients with hopeless teeth in the esthetic area requiring immediate implant restoration will be recruited to the study. Patients will be divided into two groups; a group will receive immediate implants placed using CAD/CAM guides while the other group will receive immediate implants placed by free hand technique. Accuracy of inserted implants will be measured.
详细描述
Interventions The principal investigator (DA) will diagnose all patients and select them according to inclusion and exclusion criteria.
The principal investigator (DA) will prepare all patients. Patient preparation will take few steps that are important for optimum planning of implant insertion and restoration. Actual treatment steps will start after preparation is done including; surgical and prosthetic procedures.

Medical history:
The principal investigator (DA) will ask all patients about their present and previous systemic condition and any history of hospitalization or surgeries. Controlled diabetic patients will be asked to bring a recent blood glucose test. This includes both fasting/post prandial &glycosylated hemoglobin test (Hemoglobin A1c) to evaluate their current status. 2. Dental history:

结局指标
主要结局
Linear Deviation
时间窗: two months postoperative
The amount of linear deviation was measured through three parameters; global, lateral and depth deviation. These parameters will be measured at the apical and coronal center in a mesiodistal and buccolingual plane.
