A technique describing the application of an autopolymerizing silastic material for the fabrication of a customized interpositional alloplastic implant for TMJ gap arthroplasty has been presented. The implant is easily stabilized, shows no adverse tissue reaction, and remains undisplaced under function. The implant is quickly constructed and accurately adapted to the bony architecture of the temporal bone and condylar segments.
Etomidate, a nonnarcotic, nonbarbiturate hypnotic agent, was assessed in a group of 20 patients requiring general anesthesia for outpatient oral surgical procedures. Changes in mean blood pressure, heart rate, and transcutaneous oxygen tension (PtcO2) were examined following the intravenous administration of etomidate for the induction and maintenance of general anesthesia. Clinical evidence of pain on injection, myoclonic muscle activity, apnea, nausea, and emesis were documented. A postoperative questionnaire evaluated levels of amnesia and acceptance of the drug by the patient and surgeon. No significant (P less than 0.05) change in PtcO2 occurred during etomidate infusion; however, a statistically significant but clinically insignificant change did occur in mean blood pressure and heart rate. Although myoclonic muscle activity, pain on injection, and nausea and vomiting were documented, the subjective evaluation of this agent by patient and surgeon was favorable.
A root-end induction procedure was used to treat a nonvital tooth with an open apex. This procedure was relatively fast and simple and did not require special instruments or medicaments. The procedure improved the prognosis of the involved tooth and reduced the trauma associated with surgical endodontic treatment.
