Examining the Attachment of Artificial Teeth to the Acrylic Base Through Several Adhesions and Polymerizing Techniques

Q: What is the main objective of this study?

To analyze how various adhesives and polymerizing techniques affect the attachment strength between acrylic denture teeth and an acrylic denture base.

Q: How were the specimens prepared and grouped?

Sixty teeth were divided into six groups receiving different surface treatments (including diatoric preparation, thinner, acetone, and combined conditioning), while the control group remained untreated.

Q: Which resin curing method showed stronger bonding?

Microwave-cured acrylic denture base resin displayed higher shear bond strength compared with heat-cured resin, regardless of surface treatment.

Study evaluates how different adhesives and polymerizing approaches influence the bond between acrylic denture teeth and the acrylic denture base. Heat-cured and microwave-cured acrylic resin (Acron Mc) were used after surface modifications, including diatoric preparation, thinner or acetone treatments, and combined mechanical-chemical conditioning, with an untreated control. Specimens were stored 10 days at 37°C in distilled water and assessed via shear force using an Instron universal testing machine. Microwave curing showed higher shear bond strength overall and significant differences among groups.

Background: The strength of the binding between the acrylic denture teeth and the foundation materials of dentures has been found to vary. Objectives: Analyze the various adhesives and polymerizing techniques used to attach acrylic denture teeth to the acrylic denture base. Methods: Tooth preparation and curing were done using heat-cured and microwave-cured (Acron Mc) acrylic resin. The 60 teeth were divided into six groups and subjected to different surface treatments. The second group was given diatoric preparation, the third group thinner, the fourth group acetone, the ﬁfth group diatoric acetone conditioning, and the sixth group diatoric thinner conditioning. The control group was left untreated. The mesiodistal retention grooves of the second, ﬁfth, and sixth groups were 2mm deep and 3mm wide, signiﬁcantly affecting (p < 0:01) the ridge laps ofthe acrylic denture teeth. The specimens were stored for 10 days at 37°C in distilled water before testing. The specimen was then visually evaluated after being broken by shear force delivered by an Instron universal testing machine. Results: The study revealed that the microwave-cured acrylic denture base displayed higher shear bond strength (SBS) compared to the heat-cured resin, regardless of the surface treatment applied. The outcomes indicated that the microwave-cured resin had notably lower mean values of SBS for all acrylic denture teeth in comparison to the heat-cured resin. Conclusions: The microwave-cured resin had signiﬁcantly lower mean SBS values than the heat-cured resin. The sixth group had the largest SBS compared to the other groups at the p-value < 0.05. Unlike previous studies, this work incorporates a comparative evaluation of combined mechanical and chemical treatments (grooves with thinner conditioning and acetone), aiming to generate clinically applicable modiﬁcations for enhancing denture longevity.

Introduction The loss of natural teeth is a frequent issue that needs serious consideration because the majority of individuals need to replace their lost teeth. Artiﬁcial dentures are the most preferred treatment option for older adults since they are less costly than implants and ﬁxed prostheses. Because of their chemical connection to the denture base material, acrylic teeth are usually preferred over porcelain teeth since they are easily accessible, reasonably priced, and swiftly cut [1] . In recent times, there has been an increasing interest in enhancing the adhesive strength between artiﬁcial teeth and denture bases. This is essential for maintaining the durability and steadiness of dentures, as a poor bond can result in frequent maintenance and renewals. Hence, scientists have studied various methods of surface treatment and polymerization to improve the bonding strength between artiﬁcial teeth and denture bases. Polymethyl methacrylate(PMMA)is commonly used to make denture bases due to its cost
