“…Although Javid et al . found with their mechanical measurements no significant difference between open‐ and closed‐mouth techniques, it would be interesting to verify their results with nowadays more sophisticated methodology.…”

“…The lack of relevant literature may also be caused by the methodological difficulties of establishing a reference position to measure the displacement of the prostheses. Javid et al (22) added reference depressions with a rose bur to the denture base. Their reference position was given by a fixed tripod on the table, whereas the denture was placed on an occlusal key.…”

In 21 complete denture wearers, six upper and 15 lower denture relines were performed with the open-mouth technique. The centric relation (CR) was recorded with the Central-Bearing-Point (CBP) method three times before and three times after the reline. For each registration, the right and left condylar position was recorded in three dimensions using a custom-made measuring device. The average denture displacement from an initial reference position (CR) was calculated for each registration. An upper denture reline leads to a mean displacement of 2·5 mm, both in the right and left condylar area. With an average of 2·0 mm, this displacement was smaller following a lower denture reline (right and left mean, 1·6 mm). The precision of the CBP-registrations proved 0·5 mm before and 0·3 mm after reline; hence, the measured condylar displacement after reline could not attribute to a methodological bias. This clinical-experimental study demonstrates that relining complete dentures with the open-mouth technique may lead to a substantial denture shift and thus imply inevitably clinically relevant occlusal discrepancies. It is therefore important to carefully check the occlusion at denture delivery and remount the prostheses if necessary.

“…A relined denture must be mounted on an articulator for occlusal equilibration because of the discrepancy of position. [15][16][17] The limitation of this reported technique is that if the occlusal surfaces of the denture have been ground too aggressively after the initial relining, a new denture is indicated.…”

“…6,8,9,[12][13][14] Even by using the above techniques to minimize the change in the vertical dimension of occlusion or the displacement of the denture during the relining impression, a relined denture may still be displaced. [15][16][17] This article presents a patient whose maxillary denture was relined previously, but the position was altered after the relining. The diagnosis and procedures for correcting the displaced denture are also presented.…”

The construction of a removable dental prosthesis for patients with compromised residual alveolar ridges is a challenge for prosthodontists. Flabby anterior ridges and hypermobile tissues in completely edentulous arches require special considerations during prosthetic management, especially when natural dentations remain on the opposite side. Previous studies have revealed that the displacement of flabby tissue can be reduced during impressions by controlling the applied forces via changes in factors such as the tray design, scraping of impression trays, impression material, window technique, and seating velocity of the impressions. However, there may still be some forces applied during impression or there is no even space because there are no trays supporting the vinyl polysiloxane (VPS) impression material in the open window area. Using a custom double tray with even gap between these trays and injecting light body impression material may eliminate these forces and provide accuracy due to even space for the impression material. This article is a clinical report of a patient who presented with an anterior flabby maxillary edentulous ridge opposing the remaining anterior natural teeth. A custom double tray was fabricated using the principle of the window technique. The gap between the double trays allows mucostatic impressions of flabby ridge tissue to be made with accuracy. The maxillary single denture, which was made with a custom double tray, satisfied the patient.
