Repair of fractured acrylic resin
The Journal of Prosthetic Dentistry, 1980repair of fractured dentures has received little attention in the literature. Most approaches to repairs appear to be by rote rather than based on detailed scientific study. When a fractured denture is repaired with either heat-cured or chemically (cold) cured acrylic resin, the criteria for a satisfactory repair are that: (1) the repair must be rapid,

Acrylic resin stents for marsupialization
The Journal of Prosthetic Dentistry, 1985Marsupialization is a surgical technique that may be preferred to enucleation in treatment of benign cysts. The acrylic resin obturator maintains the surgical opening during healing and assures success of the surgery. Two basic techniques to construct a stable and retentive obturator prosthesis were described.

The Pigmentation of Acrylic Resins*
Journal of the Society of Dyers and Colourists, 1969Acrylic resins may be divided into two main categories—solvent‐bome and water‐borne systems—and these have been further subdivided into two groups, namely solutions and dispersions. Problems associated with the pigmentation of acrylic resins are discussed, and methods of assessing the wetting properties of the system are mentioned.

Tissue reaction to acrylic resin
The Journal of Prosthetic Dentistry, 1976Abstract A method of investigating epithelial attachment to acrylic resin was described. Clinical and microscopic examination demonstrated an attachment of the epithelium to the acrylic resin.

B ench-curing heat-processed acrylic resins before processing is suggested for the purpose of equalizing pressure in the mold, releasing internal stress, dispersing monomer uniformly, and exposing resin teeth to the monomer.‘*2*+ Opinion varies on the exact amount of time a packed flask should bench-cure before being placed in a processing unit.

Biodegradation of acrylic based resins: A review
Dental Materials, 2010The development of different types of materials with application in dentistry is an area of intense growth and research, due to its importance in oral health. Among the different materials there are the acrylic based resins that have been extensively used either in restorations or in dentures.

Publisher Summary Acrylic resins are polymers of acrylic or methacrylic esters. They are sometimes modified with monomers, such as acrylonitrile and styrene. The most common acrylates are methyl acrylate, ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate. The resins are used either as molding powders or casting syrups.

Failure load of acrylic resin denture teeth bonded to high impact acrylic resins
The Journal of Prosthetic Dentistry, 1998Techniques for bonding denture teeth to an acrylic resin denture base remain empirical, with little consensus from the literature, among clinicians, or among dental laboratories.This study evaluated the failure load of acrylic resin teeth bonded to 2 high impact acrylic resins.The ridge lap portion on 120 identical denture teeth were modified with 3 ...

Abstract A technique for the construction of acrylic resin casts from plaster casts has been presented. The resultant casts are not exact duplicates because of the shrinkage of the wax and acrylic resin, but the appearance is the same. All of the steps can be performed by auxiliary personnel in their spare time or as a training project.

Publisher Summary This chapter focuses on the various welding techniques associated with a non-absorbing polymer named as acrylic resin. Acrylics can be tacked with the help of ultrasonic mechanism. Continuous bonding is generally unsatisfactory due to embrittlement and low strength.
