RESUMO
Part III of this four-part series about nonanatomic denture tooth development traces the evolution of this movement from the mid-1930s through the World War II era up to the early 1950s. By this time, the general preference for posterior denture occlusion had shifted from anatomic to nonanatomic teeth, and all the major denture tooth manufacturing companies listed at least one nonanatomic design in their inventories.

This second part of a four-part series concerned with the development of nonanatomic denture occlusion follows nonanatomic tooth design from the time of Victor Sears' first nonanatomic tooth patent through the mid-1930s. Many of the designs featured in this series exhibit genius, while others are pure nonsense. Sears claimed that a new nonanatomic tooth design appeared every 9 months on average during the first 30 years of nonanatomic tooth production. Many current nonanatomic tooth patents are further refinements of those earlier designs. Part II reviews pioneering designs that appeared during the first dozen or so years of this paradigm shift in denture occlusion philosophy.

The denture base polymer poly(methyl methacrylate) (PMMA) is highly susceptible for microbial colonization resulting in denture-associated infections. Over the years research has focused on ways to modify the PMMA properties via surface and chemical modification. These studies led to the development of new denture polymers that include anionic PMMA polymers. The new anionic polymers presented the possibility of compromising the physical and mechanical properties required for denture fabrication. These obstacles were overcome by generating anionic PMMA polymers with physical and mechanical properties suitable for denture fabrication. A large body of literature is available on the anionic PMMA polymers, their antimicrobial properties and their potential for the commercial and clinical application as dental biomaterials. This article describes a review and evaluation of the anionic PMMA polymers for their suitability to serve as denture base polymers, their antimicrobial properties, their efficacy to prevent denture-induced infection and their safety in the oral environment.

In the practice of dentistry in colonial times, no name shines more brightly than that of John Greenwood, the favorite dentist of President George Washington. But it is more than this alone that brings luster to his name and renown. A study of the advertisements he placed in newspapers in Massachusetts and New York gives us an insight into his treatments and his mode of practice. A newly discovered advertisement adds to our knowledge of this remarkable practitioner.

This publication is an assessment of scientific articles published in the Fogorvosi Szemle over the last 120 years dealing with the evolution of complete dentures and the treatment of complete edentulousness. Qualitative and quantitative analysis was performed to find the annual average number of scientific articles and to find the authors who published the most in this topic. Publications had been collected and categorized according to author, year and subject and an extensive comparative analysis was carried out. Nineteen authors had four or more first author publications during this time period. According to content, publications were divided into four major groups. Finally, the research activity of three academic scholars, Imre Kemény, Miklós Kaán and Géza Prágai, was introduced briefly based on their articles published in the Fogorvosi Szemle. All of them have contributed significantly to the scientific advance and the academic education of complete prosthetics.

Part III of this series of articles, like Part II, reviews the pioneering efforts in the 19th century to improve the quality of artificial teeth. The focus of this article, unlike that of Part II, is specifically modifications in the design of the occlusal anatomy of the 19th century denture teeth, along with the theories of mandibular movement that inspired those modifications. This article concludes the introductory phase of this project, which seeks to unravel the confusing history of the development of (posterior) denture teeth.
