Presentation Transcript

    2. Trans-alveolar Extraction It is essentially a technique that includes dissection of a tooth or root from its bony attachments. It is often referred to as Open method.

    3. Trans-alveolar Extraction - Indications Any tooth which resists attempts at intra-alveolar extraction when moderate force is applied. Retained roots which cannot be either grasped or delivered with an elevator. A history of difficult or attempted extractions. Hypercementosed and ankylosed teeth.

    4. Trans-alveolar Extraction - Indications Any heavily restored tooth, especially when root filled or pulpless. Impacted and dilacerated teeth. Teeth shown radiographically to have a complicated root patterns. During immediate denture treatment, where there is a need to trim some alveolar bone.

    6. Instruments used in trans-alveolar surgery

    32. Instruments used in trans-alveolar surgery Blade Handle Handles for the blades

    33. Instruments used in trans-alveolar surgery Surgical Blade #15 is the most commonly used scalpel blade. #15 is a smaller version of #10 #11 is pointed (stab incisions for Incision and Drainage). #12 is hooked

    34. Instruments used in trans-alveolar surgery Disposable Blade

    36. Handling The Instruments The scalpel is held with thumb, middle and ring finger while the index finger is placed on the upper edge to help guide the scalpel. The scalpel should never be used in a "stabbing" motion especially while raising a flap.

    38. The retractor should be placed beneath the flap and held firmly perpendicular on sound bone with no soft tissue trapped between. In order not to focus on the retractor rather than the surgical field, do not force the retractor against the MPF in an attempt to pull the soft tissue out of the field but rather the retractor is held in contact with the bone so that the flap rests on it passively.
