Oral SurgeryCarious teeth with intact crown is not an indication for open view (transalveolar) extraction. Such teeth can usually be extracted by conventional intra-alveolar method. Open view is indicated for hypercementosis, bone sclerosis, and abnormal root curvature where conventional extraction fails.

Oral SurgeryIn the extraoral technique for mandibular nerve block, the needle is inserted into the pterygomandibular space anterior to the lateral pterygoid plate and directed anteriorly to avoid damaging the maxillary artery and other important structures located posteriorly. The goal is to place the anesthetic solution around the mandibular nerve before it enters the pterygopalatine fossa.

SOLUTION Light and continuous
Use of continuous light force is recommended to be applied for adult group of patient rather than intermittent force as applied by removable appliance. This is because continuous forces are expected to bring about direct resorption of the root socket. They should hence not occlude more than a small percentage of blood vessels with in the periodontal ligament, not substantially interfere with their nutritional supply and little interference
with normal biologic functioning. In adult due to heavy force teeth may devitalize because the opening into the tooth (apical foramen) is smaller and blood vessels can be easily disrupted.
