Do you know to know more about Alt-RAMEC protocol in Class III patients?

September 26, 2018

If you need to know more about the above topics please read this paper which was written by our director Dr Mohammed Almuzian and one of the great team of orthodontists and it has been published this week at the Journal of Orthodontics/ the official Journal of the British Orthodontic Society


Objectives: To establish the effectiveness of Alternate Rapid Maxillary Expansion and Constriction combined with Protraction Facial Mask (Alt-RAMEC/PFM) approach in treating Class III growing patients compared with PFM combined with conventional Rapid Maxillary Expansion (RME/PFM).

Search sources: Unrestricted search in five electronic databases and manual searching were undertaken up to February 2018.

Data selection: Randomised clinical trials (RCTs) evaluating the effectiveness of Alt-RAMEC/PFM were selected.

Data extraction: Screening of references, data extraction and assessment of bias risk were evaluated independently by two reviewers.

Results: Five RCTs comparing the Alt-RAMEC/PFM with RME/PFM met the inclusion criteria. Small but statistically significant mean differences favouring Alt-RAMEC/PFM protocol as measured by SNA angle (1.16°; 95% CI 0.65 to 1.66), SNB angle (0.67°; 95% CI 0.32 to 1.02) and ANB angle (0.66°; 95% CI 0.08 to 1.25) were noted. Alt-RAMEC/PFM exhibited a more favourable overjet correction when compared to RME/PFM, however, differences in other dental changes were insignificant.

Conclusion: There is limited evidence with high risk of bias that Alt-RAMEC/PFM can result in a statistically significant increase in maxillary protraction compared with RME/PFM in Chinese subjects over the short-term. High-quality long-term RCTs with inclusion of patient-reported outcomes are required.
