Stage 1(2 months preoperative) – CBCT and Laboratory analysis
Presurgical implant imaging assessment includes all radiologic examinations performed previously, as well as new radiologic examinations chosen to support the implant team in formulating a definitive and comprehensive treatment plan for the patient. The goals of this phase include all surgical and prosthetic information needed to determine the amount, quality, and density of bone; the association of critical structures with the proposed implant sites; and whether or not disease is present at the proposed surgery sites (5).
It has been observed that a significant proportion of patients with a generally satisfactory dental history who have undergone laboratory screening have been found to have undetected systemic diseases, ranging from 12% to 18%. These disorders may have an impact on the implant surgery protocol or the likelihood of long-term success. The most common clinical laboratory tests are based on blood samples taken from the urine and venous system. These tests may include a CBC (complete blood count), a BMP (Basic Metabolic Panel), a Comprehensive Metabolic Panel (CMP) and bleeding disorder tests like PT (Prothrombin Time) or PTT (Partial Prothrombin Time). An A1c can also be obtained if a patient has prediabetes or diabetes, as this test measures how well the patient is managing their diabetes. (5).
