New study aims to perfect digital scans for dental implants

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 4 implants places in fully edentelous patient that is planned to be treated with implant supported overdenture \- Exclusion Criteria: Diseases / Conditions That Can Contraindicate Dental Treatment 1. Uncontrolled Systemic Conditions Dental procedures-especially invasive ones-are often postponed if the condition is not medically stable: • Uncontrolled Hypertension BP typically \>180/110 mmHg is considered unsafe for elective dental care. Risk: stroke, heart attack during treatment. • Uncontrolled Diabetes High blood glucose (e.g., \>300 mg/dL) increases infection risk and poor healing. • Uncontrolled Thyroid Disease Hyperthyroidism raises risk of thyroid storm, especially with epinephrine. 2. Recent Major Cardiac Events Elective dental treatment is usually deferred for: * Heart attack (MI) within past 6 months * Stroke within past 6 months * Unstable angina * Severe arrhythmias * Decompensated heart failure These conditions can make dental stress or anesthesia dangerous. 3. Infectious Diseases (Active Phase) Dental treatment may be delayed to protect the patient or others. * Active Herpetic Lesions (Cold Sores) around the mouth * Active Tuberculosis (TB) * COVID-19 or other acute respiratory infections with fever 4. Hematologic Disorders If blood does not clot properly, dental surgery can be risky. • Severe Thrombocytopenia Platelets too low for safe extraction or surgery. • Hemophilia or bleeding disorders Require management with a hematologist first. • Patients on certain anticoagulants (e.g., warfarin with very high INR) May need medical adjustment before invasive care. 5. Pregnancy (Certain Situations) Most dental care is safe, but some procedures are postponed: Elective treatments during 1st trimester Avoid certain medications (e.g., some anesthetics, antibiotics, NSAIDs) Severe hypertension or pregnancy complications (eclampsia) 6. Severe Psychiatric Conditions (Unstable) When a patient cannot cooperate safely: Acute psychosis Severe anxiety uncontrolled by medication Need medical stabilization vs. dental sedation coordination 7. Substance Intoxication Dental care is not performed if patient is intoxicated with: Alcohol Recreational drugs (especially stimulants like cocaine or meth) Risk of cardiovascular events or inability to consent.
