In addition, attention should be paid to the cooperation of multi-disciplinary team, which can diagnose and treat rare cases earlier and more accurately.OBJECTIVE To measure the dimensional data of complete dentures and to design a novel tray for recording maxillomandibular relationship of edentulous patients. METHODS For the measurement, 100 pairs of complete dentures from the clinic were surveyed for the following parameters a1, the distance between the middle fossa of the upper left and right first molars; a2, the anterior-posterior distance between the middle fossa of the upper first molars and the incisal edge; a3, the width of the upper denture; a4, the anterior-posterior length of the upper denture; a51, the height from the mesio-lingual cusp of the right upper first molar to the saddle surface; a52, the height from the central fossa of the right lower first molar to the saddle surface; a6, the height from the notch of the upper lip frenulum to the upper central incisor edge; a7, the least thickness of the labial saddle base in the upper central incisor region. Based on the data, the trays with different sizes were designed and fabricated, and the key and adjusted till the proper vertical dimension, after that, the putty silicone rubber impression material was added around the screw posts to record the horizontal maxillomandibular relationship, finally, the anterior surface of the tray handle was used to record the midline of the face and lower edge of the upper lip at rest and with smile. CONCLUSION The dimensional data offered reference for the analysis of restoration space in edentulous patients. The tray designed and fabricated in this study may serve as a new tool for recording the maxillomandibular relationship.OBJECTIVE To compare the changes of extracellular space (ECS) structure and local drug distribution in adult brain and aged brain
