Abstract:
The female patient was 22 years old at the time of initial diagnosis, complaining of maxillary bilateral missing teeth. The face was straight type, and the 15, 25 were missing. X-ray analysis showed the bilateral maxillary sinuses were over gasified to the alveolar crest, and the alveolar bone at 15, 25 were extremely thin. The treatment plan of this case was to extract 35 and 45, and attempted to close the space between the missing teeth. Straight wire fixed appliance was used to align the upper and lower teeth, then the space closure through the maxillary sinuses was achieved by continuous light force. The treatment lasted 25 months. After treatment, the occlusion relationship was normal. The radix dentis were parallel without obvious absorption, and the dental pulp vitality was normal.
Key words:
Extensive maxillary sinus pneumatization,
Continuous light force,
