NATURALLY INSPIRED, SCIENTIFICALLY PROVEN

Development

Because the process of manufacturing dentures had changed little in the last 100 years, our team of experts was determined to update every aspect of the process and bring dentures into the 21st century. In 1991 we began an extensive series of medical, dental and engineering studies to create the best solutions possible. The process, the science and the materials were all reviewed and thoroughly tested until we developed the proven CQR method.

The science of the CQR concept

The work began with a series of questions asked by Dr. Henry M. Tanner, DDS, MS, USC and the L. D. Pankey Institute for Advanced Dental Education. This work began with a thorough review of the dental and neuromuscular literature working from 1988 – 1993. The literature comprised almost 2000 documents dated from the 1700’s to the current year of study, 1999.

Physical examination and photography of approximately 200 skulls at the University of Texas Dental School Houston in an attempt to demonstrate consistent patterns of mandibular motion and faceted toothwear – 1991 – 2000. This clinical study was supported with continuing study of related scientific literature – dental, anatomical, neuromuscular and engineering.

In 2000, Ron Jr. offered that the paths of function visualized on the skull and tooth surfaces might have a mathematical solution. So, from 2001-2002, eight randomly selected skulls from the University of Texas Houston collection were digitally scanned in the Anthropology Department, University of Texas, Austin.

This data was used to solve for the mathematical relationship of the related wear surfaces and was completed June 2003 by Dr. Ed Henkel.

With the math solution, the anatomical “science” was complete.

In 2002 a group from the UK attended a dental continuing education course (CE) at the Uni. of Florida where a primary mentor of Ronald G. Presswood, DDS, Dr. Parker E. Mahan, was the retired department head of the school of head and neck pain which was subsequently named for him. Dr. Mahan asked Ron Presswood, DDS to share the research to date with the group course which resulted in Dr. Andrew (Andy) C. Toy and Ron Presswood, DDS becoming acquainted. This relationship evolved through several study club meetings in which muscle function studies were taken on the attendees. These efforts and Andy Toy’s introduction created a working relationship with Loughborough University (LU), in England.

Through the facilities and faculty (Dr. Matthew Pain and Dr. Stephanie Forrester) at LU almost 5000 neuromuscular trials were performed on almost 60 subjects over a 7 year period. These trials and resultant papers were the original work of this sort in dental science.
