Endodontic surgery has evolved from a conventional surgery to a microsurgery.Owing to this fundamental change ,we can now locate and treat second and third molars plus palatal root.The prognosis of Endodontic Surgery can be affected by the presence of serious anatomical elements such as the maxillary sinus. In such case, the surgeon will be facing two situations: whether the apex is in close contact with the sinus membrane,the apex is in the sinus. Retro preparation and retro filling will be performed thru sinus cavity instead of bone cavity. Besides, new retrotips are to be used during the surgery; manufactured according to a specific design facilitating the access to the posterior area and also deeply inside the sinus cavity . The objective of this new technique is to increase the rate of success of the surgical act for Difficult Endodontic Conditions and to cure formerly incurable teeth.
Dental ImplantSurgical Endodontics : Patient v/s Dentist Preferences
Extracting a tooth and replacing it with an implanttrying to save an existing natural tooth? Implantology and endodontic surgery are two highly evolving procedures in terms of instrumentation, used material and surgery procedure. But which one should be chosen, when and how? Does the choice depend on the success rate of the procedurewould the clinical case itself determine the treatment plan? In addition, two factors are worth considering: the mental state of the patient who is preserving his/her natural teeth and his/her financial situation. The aim of this presentation is to make a differential diagnosis and to select the cases to be treated. Both procedures will be detailed according to the selected cases.
Get up your nerve to deal with the mandibular nerve
The paresthesias of the inferior dental nerve consists of a complication that can occur after performing various dental procedures such as cystectomies, extraction of impacted teeth, apicoectomies, endodontic treatments, local anesthetic deposition, preprostheticimplantologic surgery. The possible mechanisms of nervous lesions are mechanical, chemical and thermal. Mechanical injury includes compression, stretching, partialtotal resection. This could be done during surgical procedure to laterally reposition the mandibular nerve in preparation for placement of implantsextraction of the lower third molarduring endodontic surgery to take off overfilling materials from the mandibular canal. Chemical trauma can be due to certain toxic components of the endodontic filling materials and irrigating solutions .Thermal injury is a consequence of bone overheating during the execution of surgical techniques. We present different clinical cases of paresthesia of the inferior dental nerve to explain the etiology and the treatment of this complication step by step.
