Princinples of Tooth Extraction

  1. 1. Principle of Uncomplicated Exodontioa
  2. 2. Outline Presurgical Assessment Preparation Mechanical Principles Forceps Principles Summery
  3. 3. Presurgical Medical Status Bleeding Infection Preexisting disease
  4. 4. Presurgical Indications of Removal of Teeth: Severe carious Severe periodontal disease Orthodontic treatment Impacted teeth Preradiation Economins
  5. 5. Presurgical Contraindications of Removal of Teeth: Systemic Contraindications Severe uncontrolled metabolic diseases Uncontrolled leukemias and lymphomas Severe myocardial ischemia Bleeding tendency Pregnancy Taking medications Local Contraindications Radiation Tumor
  6. 6. Presurgical Clinical Evaluation Access Mobility Crown Condition Radiographic Examination Relation to vital structures Configuration of roots Condition of bone
  7. 7. Mechanical Properties Widge Wheel and axleLever
  8. 8. Lever Elevators primarily. Purchase point can be made and a crane pick can be used to elevate the tooth. Straight elevator help mobilize teeth without the preparation of a purchase point.
  9. 9. Widge 1) Extraction Forceps 2) Small Elevators
  10. 10. Wheel and Axle Triangular Elevator Multiple-rooted tooth is left in the alveolar process
  11. 11. Forceps Use Goals of forceps: a) Expansion of bony socket b) Removal of tooth from sockets 1) Apical Pressure Bone expansion Center rotation 2) Buccal Pressure 3) Lingual Pressure
  12. 12. Forceps Use 4) Rotational Pressure Maxillary incisors Mandibular premolars 5) Tractional Force For delivery!
  13. 13. Forceps Use Variety of forces can be used to remove a tooth. Apical force is always useful and should be always used when forceps is adapted. Most teeth are removed by combination of buccal and lingual forces. Rotational movements are useful for single-rooted conical teeth with no severe curvatures at the root end.
