Introduction: Palatoplasty of the patient to feed and practice speaking make the upper jaw is narrower than normal. This study aims to investigate the effect of rotation of upper first molar in clefts patient
Method study: This research is a cross-sectional descriptive study in November to December 2022. The sample group was 32 clefts patient. The tool is a data recorder from dental model before and after treatment with a quad helix jaw extender. The data of pre-treatment and post-treatment by rotation of permanent upper first molar with a quad-helix jaw extender were collected and compared. Data were analyzed by descriptive statistics, pair t-test statistic and multiple regression.
Results: 1) After rotation of upper first molar in clefts side and normal side, there was a statistically significant increase in the alignment gap of the upper molar (p≤0.05). 2) Gap of the upper molar after rotation was not different between the rotation of the first molar in cleft side and normal first molar. 3) Rotation of the first molar statistically significant correlated with the occurrence of molar alignment gaps (p≤0.05).
Conclusion: The rotation of the upper first molar create spaces for fixing the overlapping teeth leading to correct occlusion of the upper and lower teeth. It leading to reduce permanent tooth extraction.
