Dimensional accuracy of denture resin cured by microwave energy

A comparison of three dimensional change in maxillary complete dentures between conventional heat polymerizing and microwave polymerizing techniques

“…These results are consistent with several reports. 21,22 Nelson et al 23 also found that the amount of movement of artificial teeth in MP specimens tended to be greater than in HP specimens. Our results might be similar to their results.…”

The Use of Microwave Energy in Dental Prosthesis

“…Considering dimensional alteration of denture or bases resin, when conventional water bath and microwave energy were compared, some authors (Reitz et al, 1985;Levin et al, 1989;Uchida et al, 1989;Takamata et al, 1989;Al-Hanbali et al, 1991;Nelson et al, 1991;Wallace et al, 1991;Sanders et al, 1991;Barbosa et al, 2002;Keenan et al, 2003) found no difference between the two techniques; also, these results are not in agreement with others (Sanders et al, 1991;Nelson et al, 1991). Sanders et al (1991) observed in their study that microwave polymerization provided a lower degree of artificial tooth movement, while Nelson et al (1991) reported a greater degree of tooth positional changes when microwave polymerization was employed.…”

Dimensional Accuracy of Acrylic Resin Maxillary Denture Base Polymerized by a New Injection Pressing Method

“…These methods include macroscopic evaluation of denture base adaptation using paste material cast directly in the oral cavity19), evaluation of the weight of silicone fitness test material16,17), and measurement of the rise or linear shrinkage of the denture base using a plaster model or dye18, [20][21][22][23][24][25][26]. In the present study, we measured the space between the denture base and the model after placing the denture back onto the cast.…”

“…Thus far, base plate type19, 20,25,26) and denture type using arranged artificial teeth16,7,21-24,26) have been used for samples. Factors affecting adaptation, such as the presence of arranged artificial teeth25) or sample thickness18), were considered.…”
