CBCT evaluation of maxillary sinus changes with expanders

Discussion of “ CBCT EVALUATION OF SKELETAL, DENTAL, AND VOLUMETRIC MAXILLARY SINUS CHANGES ASSOCIATED WITH TWO TYPES OF MAXILLARY EXPANDERS” Ron Snyder, D.D.S. Apple Valley, Minnesota 80th Annual Midwest Angle Component Meeting Orlando, Florida

CHECKLIST for DISCUSSER ,[object Object],[object Object],“ The purpose of this study was to assess three dimensionally, with the aid of ICat technology, the maxillary skeletal, dental, soft tissue, and volumetric airway changes associated with the banded versus the bonded hyrax expanders.” I would have liked more background on the relevance of maxillary sinus volume in its relationship to airway dynamics

Suture opening not measured in this study T2 at 6 months post active expansion

T here were significant midpalatal suture openings P <0.05) ,[object Object],[object Object],[object Object],[object Object],The midpalatal suture opening was parallel.

Differences may be due to lack of suture opening?? Or not enough over expansion and subsequent uprighting with palatal arch? Clinical suggestion…upright molars before expansion to maximize expansion and reduce side effects

IV. Discussion and Conclusion 1. Discussion CHECKLIST for DISCUSSER “ The decrease in opening of the posterior part of the maxillary suture was attributed to the interlocking of the pyramidal processes of the palatine bone along with immobilization of the medial and lateral pterygoid plates of the sphenoid bone.” ??????????
