Five years experience with a new intraoral maxillary distraction device (RID)

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Craniofacial Surgery

Background:

• Severe retromaxilla requires effective treatment modalities.
• Maxillary distraction osteogenesis is a recognized surgical technique.
• Existing devices may have limitations in surgical exposure and patient comfort.

Purpose of the Study:

• To evaluate the efficacy and patient experience of a novel intraoral maxillary distraction device.
• To assess the degree of maxillary advancement achieved with the new device.
• To compare the new device with existing maxillary distraction systems.

Main Methods:

• Retrospective case series of 19 patients treated since 2004.
• Utilized a new intraoral device for maxillary distraction osteogenesis.
• Measured maxillary advancement using lateral cephalograms.

Main Results:

• Successful maxillary advancement in all 19 patients.
• Mean advancement of 9.6mm (range 4-17mm).
• The new device demonstrated reduced surgical exposure, fewer implanted materials, and enhanced control during distraction.

Conclusions:

• The novel intraoral device is effective for treating severe retromaxilla.
• This device offers improved surgical outcomes and patient comfort compared to traditional methods.
• The device is psychologically well-accepted and comfortable for patients undergoing maxillary advancement.
