Bibre construction: indirect method
A 2 mm symmetric advancement wax bite was made for the patient. Maxillary and mandibular impressions were taken, and the poured models were mounted on an articulator using the wax bite. A separating medium was applied to the models and allowed to dry. Complimentary inclined bite raisers were constructed on the occlusal surfaces of 2 occluding molars or premolars on the patient's model using light cure glass ionomer, triad gel, compomer, or colored filled composite. The selection of sites for
Diagnosis and etiology
A 13-year-old girl reported to the clinic with the chief complaint of an unpleasant profile. Clinical examination showed a convex profile with accentuated mentolabial sulcus. She showed a nonconsonant smile. The patient was in the permanent dentition stage. She had Class II molars and canines, with 8 mm of overjet and complete overbite. She had mild maxillary and mandibular arch crowding (Figs 2 and 3). The panoramic radiograph showed normal bone and tooth forms with developing third molars.
Diagnosis and etiology
A 13-year-old girl reported to the clinic with the chief complaint of deep overbite. Clinical examination showed a convex profile with an increased nasolabial angle and accentuated mentolabial sulcus. The patient was in the permanent dentition stage. She had Class II molars and canines, with 3 mm of overjet and 50% overbite. She had mild maxillary anterior arch crowding (Figs 10 and 11). The panoramic radiograph showed normal bone and tooth forms with developing third molars. Cephalometric
Discussion
The results of our two cases reports showed correction of Class II malocclusion and improvement of the facial profile. This finding was achieved using bonded maxillary and mandibular inclined bite raisers used in conjunction with fixed appliances and short light Class II elastics.
There are obvious advantages to the use of the BIBRE over various fixed functional appliances; it is inexpensive, easy to fabricate, adjust, and replace chair-side. It is also unobtrusive, easy to clean by the patient,
Conclusion
The BIBRE combined with light and short intermaxillary elastics can correct Class II malocclusion and improve the soft tissue profile.
