THIRD MOLAR ERUPTION PREDICTOR |
摘要 |
Provided are materials and methods for predicting whether a molar tooth will remain impacted or will erupt based upon anatomical measurements of the position of the teeth in relation to the ascending ramus of the mandible. A transparent template is superimposed on the panoramic tomograms of the patient teeth and mandible. Pre-printed profiles and reference points are aligned on the tomograms with the apexes of the molars. The distance between the profile of the mandible and the pre-positioned reference points allow making a prediction on third molar eruption.
