RESUMEN
PURPOSE: To evaluate the usefulness of glassfiber-reinforced composites post and core in restoration of serious dentine defects. METHODS: 59 cases, 87 teeth with serious dentine defects were selected. Glassfiber was used as the reinforcement frame and glassfiber-reinforced composites post and core were fabricated. Then the defected teeth were restored with porcelain-fused-metal crown. All patients were asked to re-visit 3 months, 6 months and 12 months after treatments. RESULTS: 2 cases (3 teeth) were out of visit 12 months after treatments. The restorations of other 57 cases (84 teeth) were firm and the occlusion was rebuilt satisfactorily during 12 months' clinical observations. Only one crown restoration was found to be loose. But the post and core was found to be still firm after the crown was taken off. Satisfactory results were achieved after being restored again. No dentine fracture was found in all restored teeth. The clinical results were satisfactory. CONCLUSION: Glassfiber-reinforced composite can be considered as a good material to fabricate post and core due to its high-strength, aesthetics and convenient operation.

48 patients with fractures of the jaw bones were included in this study. Intermaxillary fixation screws were used for tractions between the upper and lower jaw and to regain occlusion relationship, followed by internal rigid fixation. Two days after reduction of the fractures, intermaxillary tractions were carried out and the fixation screws remained for 2 weeks. All the wounds healed primarily with good occlusion. The wounds for screw placement healed well 3 to 5 days after removal of the screws. Excellent occlusion recovered in 45 patients, while in 3 patients, mild open bite developed which returned to normal after 2 weeks of intermaxillary tractions. It is concluded that intermaxillary fixation screws are time saving and efficient in the management of jaw fractures.
