“…Our study resembling Sheridan et al's report showed that the peak formaldehyde release, which was one of the most important factors of cytotoxicity, was observed during the first 24 hours and subsided over time. Except for Tsuchiya et al [21], who determined formaldehyde release similar to the present study, other researchers have evaluated just free methyl methacrylate monomer [19,22,24,27]. However, formaldehyde is more cytotoxic than methyl methacrylate, even at lower concentrations [21].…”

“…MMA molecules can be associated with saliva's proteins making large molecules responsible for oral tissue allergic reactions [17,18]. Cheilitis, stomatitis, burning mouth, and painful sensation are some side effects of resin acrylic materials reported in people who have received a complete or partial denture [19]. All cells in the human body contain some amount of formaldehyde, which is produced due to the metabolism of serine, glycine, methionine, and other amino acids in the human body [4].…”

Background/Purpose. The biocompatibility and cytotoxicity of formaldehyde and monomer are essential in resin-based denture’s byproducts. This present study was performed to compare the release of formaldehyde and monomer and biocompatibility of three brands of heat-curing acrylic resins, including Ivoclar, Bayer, and Acropars, with different mixing properties and the same processing methods. Materials and Methods. In this experimental in vitro study, 18 samples were fabricated from Ivoclar, Bayer, and Acropars heat-curing acrylic resins (each group consisting of 6 samples). The released formaldehyde and monomer level were measured and registered for 1, 7, and 30 days. Also, methyl methacrylate release from samples was used to test cell cytotoxicity using L-929 murine fibroblast. The data were analyzed with repeated measures, one-way ANOVA, and Kruskal–Wallis tests. Results. For formaldehyde release of 1 day, Ivoclar acrylic resin showed the lowest level, followed by Bayer and Acropars acrylic resins ( P < 0.05 ). On 7 and 30 days, Bayer acrylic resin released the lowest formaldehyde, followed by Ivoclar and Acropars acrylic resins ( P < 0.05 ). Acropars showed the weakest and most significant results regarding biocompatibility and monomer release in all three points of time, respectively ( P < 0.05 ). Conclusion. Acropars acrylic resin showed the most significant formaldehyde and monomer release and least biocompatibility compared to Bayer and Ivoclar for 1, 7, and 30 days; however, after 30 days, all three resins displayed the same amount of formaldehyde release.

Removable prosthesis is probably one of the oldest types of dental therapy used to rehabilitate patients with complete or partial edentulousness. The main function of the edentulous alveolar ridge is to provide a major area of support for the dentures.1 Ill-fitting prosthesis leads to a condition where there is no longer adequate support of bone due to RRR. Hence, rehabilitation of such cases pose a clinical challenge, as there is a decreased denture foundation area for support, retention and stability.2 Residual ridge resorption (RRR) is the severe atrophy of alveolar bone underlying the mucoperiosteum. RRR affects the alveolar bone morphology, resulting in a decreased denture foundation area and increased inter-alveolar ridge space. The increase in inter-ridge distance provides a huge restorative space which results in a heavier complete denture due to greater volume of denture base material. This increase in restorative space amalgamates with the long lip length of the patient which gives rise to huge challenge to the success of the complete denture. Also, decreased denture foundation area increases the heaviness of the prosthesis and negatively affects the retention of the denture due to gravity.3 Various weight-reduction techniques have been used in the past using a rigid three-dimensional spacer, such as dental stone (Ackerman, 1955), cellophanewrapped asbestos, silicone putty during laboratory preparation to keep denture base content out of the intended hollow cavity of the prosthesis. The following case report describes a distinct lab technique for construction of hollow maxillary complete denture for a patient with severe RRR.
