Alsharbaty MHM, Alikhasi M, Zarrati S, Shamshiri AR. Comparison of denture tooth movement between CADCAM and conventional fabrication techniques. Movable tissues such as the vestibule and soft palate were extremely unstable in some cases; therefore, the performances of the DI and CI methods were compared only in the supporting areas. Yoon HI, Hwang HJ, Ohkubo C, Han JS, Park EJ. (right) Occlusal plate with applied rim; unlike the conventional occlusal rim, this is designed to be easy to use with a large surface area to record the bite or for gothic arch tracing. Since the trays could be easily fixed using modeling compound, the process of making a definitive impression with polyvinylsiloxane impression material was also simple. Impression acquisition methods using an intraoral scanner are gradually gaining popularity in the dental field.1 These techniques are commonly used in the partially edentulous jaw; in case of completely edentulous, several errors may occur due to lack of anatomical indicators. • It gives all the information of a CT but, at 1/8th the radiation dose and at a lower cost.

Accuracy of computeraided design/computer-aided manufacturing-generated dental casts based on intraoral scanner data. Therefore, a comparative study on the differences between impressions obtained through the various techniques is needed. 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. Five volunteers (four men and one woman; mean age, 62.7 years) with maxillary and mandibular edentulous jaws were included. In the SI method of the present study, a new tray was designed to facilitate efficient, simultaneous determination of the VD, CR, and anterior tooth positions in a preliminary impression model as follows. 2, 3. Color deviation map of superimposition of the areas recorded by the CI and DI methods; ‘Red’ or ‘Yellow’ color means less depressed CI impression technique, and ‘Blue’ color means more depressed CI impression technique. A difference in the value of the residual ridge was 0.11 ± 0.17 mm and that of the buccal shelf was 0.09 ± 0.15 mm. Compared with the CI method, the SI method achieved somewhat different results; however, the overall difference was not significant.

The mandible was subjected to less pressure under the DI method and had a difference of 0.04 ± 0.05 mm. Comparisons of the CI and SI methods were made at five different regions of the maxilla and mandible.32 Due to limitations of the DI method in making the impression of movable tissue, the CI and DI methods were compared at four areas of the maxilla and two areas of the mandible. Inferior alveolar nerve injury in implant dentistry: diagnosis, causes, prevention, and management. McLaughlin JB, Ramos V Jr. The handle of the mandibular tray was also omitted, a short rim was created at the anterior position, and the CR was set by biting down with the maxillary plate. 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. CI and SI methods were used to obtain dental stone models (Zostone, Shimomura Gypsum Co., Ltd., Saitama, Japan) following conventional procedure, and the STL-model cast file was obtained using a model scanner.

The purpose of this study was to compare two novel impression methods and a conventional impression method for edentulous jaws using 3-dimensional (3D) analysis software. Statistical analysis was performed using Statistics Package for the Social Sciences software (SPSS version 23.0, SPSS Inc., Chicago, IL, USA). 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. Logozzo S, Zanetti EM, Franceschini G, Kilpela A, Makynen A. The difference in the edentulous supporting areas between the CI and DI methods was not significant (P>.05).

In a similar manner, the mandible was scanned from the retromolar pad on one side to the contralateral side along the residual ridge, followed by buccal vestibular scanning with retraction of the lip and cheek; finally, the lingual vestibule was scanned with retraction of the tongue. 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. Mean area displacement was measured using CI method to evaluate differences in the impression surfaces as compared to those values obtained using SI and DI methods. (left) Occlusal view, (right) lateral view of both the novel maxillary and mandibular trays; the closed-mouth technique is performed by biting the maxillary occlusal plate and the mandibular anterior short occlusal rim using the bimanual method.
