First, there was no significant difference between the open-mouth CI method and closed-mouth SI method in maxillary and mandibular edentulous patients. J Prosthet Dent 2015;114:493–497. Recent advances in removable prosthodontics include biofunctional prosthetic system (BPS), which closely replicates aesthetics, comfort, functional, and phonetic aspects of natural dentition. (A) Areas compared by the CI and SI methods; (left) 1. In addition, obtaining an impression of the complete edentulous arch has several challenges due to inappropriate shape and size of the scanner. The sublingual crescent extension and its relation to the stability and retention of mandibular complete dentures. However, a closed-mouth impression method performed with a digital device would have poor reliability if there are significant differences in the impression as compared to that through existing conventional techniques. The closed-mouth impression technique involves making an individual tray containing an occlusal rim in the preliminary model and, subsequently, the definitive impression in which the maxillary and mandible occlusal rims are in contact with each other; provisional VD and CR are simultaneously determined. 2019 Dec;11(6):350-357.

The conventional individual tray for complete dentures was produced in three steps of making the preliminary impression, stone model, and tray comprising auto-polymerized resin and required an extended amount of time. Chaware SH, Fernandes F. Tissue stress evaluation at border seal area using patient-manipulated custom tray-modified closed-mouth functional technique for flat mandibular ridges. J Int Oral Health 2018;10:77–82. The results of this study are consistent with those of previous studies on impression using the closed-mouth functional technique.37 Clinically acceptable extension of the lingual border is a key factor to enhance the retention of the mandibular complete denture.36 Our results demonstrated that the SI method can improve retention of the mandibular denture. The conventional open-mouth technique of impression-making is validated and widely used in fabricating the complete denture,15 but it is time consuming and requires additional information of the VD, CR, and anterior tooth position; therefore, it is advantageous to apply a closed-mouth impression technique for the digitization of complete dentures. This method has the advantage of reducing the number of clinic visits since definitive impression can be achieved through definitive intermaxillary relationship.16, 17 Closed-mouth technique with digital device, as the method of choice for making the impression, allows the achievement of more accurate impression surface and VD and CR values at a shorter time-period compared to existing conventional techniques.

Our study highlights that it is possible to fabricate complete dentures in a single day in the near future. The plate of the maxillary tray was moved to the anterior, posterior, superior, and inferior positions of the maxillary anterior teeth and subsequently fixed with resin (Revotek LC, GC Corporation, Tokyo, Japan); a definitive impression was obtained using the conventional method.28 The mandibular tray was applied to the edentulous mandibular ridge while the maxillary impression was positioned in the mouth. Second, there was no significant difference in the supporting areas between the DI method and CI method in edentulous patients. ... with the more recent emphasis on aesthetic recovery, patient satisfaction with implants is similar to that with natural teeth. Contour of lingual surface in lower complete denture formed by polished surface impression. The preset CR and VD were rechecked after molding of the mandibular border, and a definitive impression was made using the closed-mouth technique.31. Gan N, Xiong Y, Jiao T.

However, that day is not far off. However, in the case of edentulous mandibular impressions, the SI method could be the causal factor for the impression results because the patient's mouth is closed and the impression is made to withstand the patients' muscle strength and tongue movement; the tongue movement resulted in extension of the border of the impression in the lingual vestibule area.
