RESUMO
This article is a historical review of the development of the lingualized occlusion concept over the past century. It focuses on the pioneers of lingualized occlusion and their designs rather than on techniques for achieving a lingualized complete denture occlusion.

This fourth and final 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 end of the 20th century. Part IV concentrates on nonanatomic teeth developed during the last five decades of the 20th century. Many of the designs featured in this series exhibited 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.

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.

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.

Part I of this two-part article concentrates on the early 20th century origin of the nonanatomic concept of complete denture occlusion. It focuses on Dr. Victor Sears, who in 1922 made a courageous departure from convention when he introduced the design for his "Chewing Members." Development of these teeth marked the birth of the School of Nonanatomic Denture Occlusion. Dr. Sears' 35-year journey of research and development is traced here through his mid-1950s association with Dr. Simon Myerson. Their Myerson-Sears design set the standard for flat-planed, nonanatomic denture teeth for the next half century.

This article is a historical overview of Dr. Alfred Gysi's contributions to the profession in the areas of denture tooth and articulator design. His understanding of occlusion and mandibular movement resulted in denture tooth designs and occlusal concepts still in widespread use.

This paper describes a previously unknown denture constructed from hippopotamus ivory. The denture is unusual in that it is anatomically correct in terms of tooth morphology. It is believed that it was a demonstration item for the Great Exhibition of 1851.

This article discusses key turning points in removable partial denture (RPD) philosophy. Early advancements tended to focus upon improving the technical quality of the prosthesis itself. The beginning of the 20th century brought significant public pressure upon the dental profession due to consequences associated with poor quality fixed prostheses. The result was dramatic improvement and heavy demand for RPDs. Technical and efficiency issues conspired to temper this enthusiasm, eventually resulting in reduced respect for RPDs. By highlighting key writings and technical issues during these periods of change it is hoped the reader will gain a more precise understanding of the current status of RPD philosophy.
