“…Microscopic measurements of the posterior border gap [11][12][13][14][15][16] and weighing a elastomeric material impressed under a denture base 11,[17][18][19] are one of the most frequently used methods to evaluate the denture adaptation to a master cast due to their simplicity and feasibility. The magnitude of the palatal border gap can express the ability of a border seal, and the weight of an impression material indicates the overall volume of internal space under denture base, which are all important factors in complete denture retention 8) .…”

This study examined the adaptation accuracy of acrylic denture base processed using fluid-resin (PERform), injection-moldings (SRIvocap, Success, Mak Press), and two compression-molding techniques. The adaptation accuracy was measured primarily by the posterior border gaps at the mid-palatal area using a microscope and subsequently by weighing of the weight of the impression material between the denture base and master cast using hand-mixed and automixed silicone. The correlation between the data measured using these two test methods was examined. The PERform and Mak Press produced significantly smaller maximum palatal gap dimensions than the other groups (p<0.05). Mak Press also showed a significantly smaller weight of automixed silicone material than the other groups (p<0.05), while SR-Ivocap and Success showed similar adaptation accuracy to the compressionmolding denture. The correlationship between the magnitude of the posterior border gap and the weight of the silicone impression materials was affected by either the material or mixing variables.

“…Injection molding techniques using thermoplastic resins have gained popularity in recent years as they are free from residual monomer and porosities. In addition, polymerization shrinkage is compensated by the continuous injection of the resin at a certain pressure 14 . They also have high impact strength and resistance to cracking in addition to their superior esthetics.…”

“…They also have high impact strength and resistance to cracking in addition to their superior esthetics. Several studies have reported on the improved adaptation accuracy of injection molding techniques when compared to conventional heat cured processing [14][15][16][17][18] . However, injection molding is an expensive technique that requires special laboratory equipment as well as skilled technicians 19 .…”

Objectives: to compare between adaptation accuracy of metallic denture base and injectionmolded denture base for the edentulous maxillary arch. Materials and Methods: Ten stone casts were obtained from duplicating an educational model of a maxillary edentulous arch. The casts were divided into two equal groups; group I received metallic denture bases while group II received denture bases constructed from injection-molded Thermopress. The dentures and their respective casts were sectioned and gap measurements were made in the mid-palatal and crestal areas using a travelling microscope. Results: gap measurements at the mid-palatal areas were significantly higher than those at the crestal areas in both groups. On comparing the two groups, there was no significant difference between the two groups both at the crestal and mid-palatal areas. Conclusions: Metal denture bases and injection molded dentures base show comparable levels of adaptation accuracies and are both suitable alternatives for heat cured PMMA denture bases.

“…Acrylic resin polymer was first introduced in mid-1940s, commonly used for removable prostheses fabrication due to its favorable working characteristic, excellent aesthetics, adequate mechanical strength and inexpensive [1,2]. In order to fabricate a comfortable and fitting denture, the base should be dimensionally stable with good adaptation and border seal [3]. However, shrinkage and expansion of the material during processing procedures are virtually inevitable, leading to development of new processing methods such as rapid heat-cured, injection molding and microwave activated technique [4][5][6].…”

Acrylic resin is commonly used to fabricate removable prostheses due to its adequate physical, mechanical properties and cost effectiveness. There has been continuous development of the materials to improve their properties and to widen its application in different clinical setting. To study the history development of the acrylic resin and elaborate on the properties of different types and the processing methods of acrylic resins used to fabricate denture base which are commercially available in the market. This would help the dental clinician in choosing the best material of choice. The authors have summarized the history, development and classification of different types of acrylic resins used in fabricating denture and processing methods based on all the published research available on this topic using published materials available in the Dental Library, University of Malaya and the database (Science Direct, PubMed). Every type of acrylic denture base material has its pros and cons. Therefore, careful selection of material and the processing method is crucial to ensure the best outcome for prosthodontic treatment. Hence, upholding the patients' best interest and improving their quality of life. www.adum.edu.my
