Solow","doi":"10.1080/08869634.2022.2031170","DOIUrl":"https://doi.org/10.1080/08869634.2022.2031170","url":null,"abstract":"Centric relation (CR) is defined as “a maxillomandibular relationship, independent of tooth contact, in which the condyles articulate in the anterior-superior position against the posterior slopes of the articular eminences [1].” There is a clear anatomic-biomechanical rationale for using CR for occlusal analysis and predictable treatment with restorative dentistry, orthodontics, and orthognathic surgery. Accurate occlusal analysis requires that the condyles are fully seated in CR. With this information, the clinician can design treatment to function in harmony with the anatomic requirements of the masticatory system. All clinicians and researchers need a thorough understanding of the physical reality of the masticatory system in which they are tasked to diagnose and solve structural problems. 1. CR in the healthy temporomandibular joint (TMJ) is a precise anatomical position dictated by the elevator muscles vectors of force. The masseter and anterior temporalis muscles align the condyles in the most anterior-superior direction, and the medial pterygoid muscles align the medial pole of the condyles medially so the condyles are braced in three dimensions against the temporal bone [2]. This is a close packed position, as shown by the sagittal and coronal sections in dissection studies [3]. CR creates a transverse horizontal axis, which is consistently recorded by pantographic tracing, central bearing point devices, or an anterior deprogrammer marked by the opposing incisor [4]. These devices substitute a single mechanical point for teeth with occlusal interferences, allowing proper condylar seating. If CR was not a precise position, a consistent recording could not be achieved. 2. If teeth prevent the condyle from seating in CR, the condyle is positioned inferiorly away onto the incline of synovial fluid-lined articular cartilage, a completely unstable position. Constant lateral pterygoid muscle contraction must substitute for bony bracing. Ideal lateral pterygoid protrusive activity is reciprocal to elevator muscle closing activity [5]. When the lateral pterygoid cannot rest during closure, muscle hyperactivity may lead to pain and compromised chewing patterns. 3. Treatment planning from a tooth-dictated position like maximum intercuspation (MI) incorporates the error from the seated condylar position, precluding predictable treatment. Cordray found the mean dimension of this error in the condyles to be 0.86 mm horizontal and 1.8 mm vertical [6]. Chang showed that the error from CR to MI can profoundly detract from orthodontic results [7]. The mandible always closes with the same anatomicbiomechanical principles. Since the mandible is a Class III lever system with the elevator muscles positioned between the TMJ and teeth, elevator muscle contraction always seats the condyle in its 3-D braced position unless a tooth or restoration interferes. When the condyle loses dimension, the unchanged elevator muscle vectors seat the condyle toward its former ","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126001532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Türp","doi":"10.1080/08869634.2022.2031172","DOIUrl":"https://doi.org/10.1080/08869634.2022.2031172","url":null,"abstract":"I thank dental colleague Dr. Solow for his valuable commentary on my recent editorial regarding the usefulness (or non-usefulness) of the term “centric relation” [1]. Academic exchange and academic dispute are essential for progress in dentistry and medicine. For this reason, I would also like to thank the editors for giving me the opportunity for this response. I fully agree with Solow’s notion that “[a]ll clinicians and researchers need a thorough understanding of the physical reality of the masticatory system in which they are tasked to diagnose and solve structural problems.” At the same time, however, his letter reflects the major differences between the traditional occlusion-centered perception (for which he stands) and a more recent biologically oriented interpretation of mandibular function (for which I stand). These views cannot be reconciled. Instead, in the words of the American philosopher of science, Thomas Kuhn [2], we are dealing with two incommensurable paradigms: While Solow favors concepts of machine-like precision (using words such as “accurate,” “ideal,” “precise,” and “simultaneous”), I have argued for the abandonment of a term (“centric relation”) that originally claimed to define the only “ideal” condylar position. Because this term has been redefined so many times and in so many contradictory ways over a period of several decades, it has become obtuse and useless. Meanwhile, the natural phenomena of occlusion and jaw relationships do not care for the ever-new theoretical concepts pouring out of human brains. In the past, I have presented my view of occlusion, condylar positions, and related topics in a number of publications [3–16]. The interested reader may wish to consult the cited publications to form his or her own judgment about the validity of my interpretation of the available literature. On the other hand, some of the external evidence Solow cites to back up his statements appears questionable. To give one example: the article by Crowley et al. [17] in support of a “closed pack position” of the mandibular condyles induced by the three jaw closing muscles in living humans was based on studies of human cadavers. The intraand interindividual variability of biological and, thus, human, phenomena is so great that a comparison of humans with technical devices (or cadavers) is not permissible: each individual person is unique, while machines, produced in large numbers, are identical and function identically. I would like to conclude with a quote from Canadian orthodontist Bruce Ross, who stated about 20 years ago that “an analysis of the dentitions of a large group of orthodontists or prosthodontists would reveal a large percentage with untreated, imperfect occlusions” [18]. Should they be treated for these imperfections – and if so, by whom?","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132401052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

I suffered from TMJ disorders for years without a real understanding of what they were until, in my junior year of dental school, I identified with descriptions of symptoms and became a professional patient. CRANIO did not yet exist! There were a multitude of continuing education courses for dentists, and although I was just a student, I went to several. I then became the patient at many of these courses and was put into centric relation (CR) position by the “experts.” I had mounted models, and learned I had worn through the enamel on the cusp tips of all my posterior teeth. During my senior year, I had 16 gold onlays on my posterior teeth and an ill-fated attempt at adding a cuspid rise to my group function occlusion with gold lingual pin-ledge restorations on 6 and 11; both teeth had 2+ mobility within 2 weeks, and the restorations were removed. An attempt to add cuspid rise was aborted due to severe mobility, but I continued being treated with equilibration on my gold onlays. Upon graduating in 1977, I started going to the American Equilibration Society and Academy of Head, Neck and Facial Pain meetings. I am not sure if I started reading CRANIO with issue one, but the first time I saw it, I was hooked! I am forever grateful to Riley Lunn for filling the desperate need with the CRANIO Journal. I now humbly assume Riley’s role as Editor-in-Chief of CRANIO. I have been a reviewer for many years and, more recently, the Craniofacial Pain Editor. I have written several Guest Editorials, including “TMJ, The Great Imposter has a Co-conspirator: Poor Sleep” for the issue announcing CRANIO adding sleep to become “The Journal of Craniomandibular and SLEEP Practice.” We are currently in the era of Evidenced-Based Medicine (EBM), but there are costs as well as benefits to EBM. Frequently, the big picture is left behind as we focus on studies with only a couple of variables and ignore whole body evaluations. Drug studies and psychological studies are perfectly suited for EBM, but often, in terms of clinical pain treatment, “better than placebo” is a very low bar. A statistically significant difference does not necessarily have clinical significance in a patient’s quality of life. Most studies do not examine attempts to correct or even address problems in their entirety. This month’s Guest Editorial is written by Dr. Jennifer Hobson and Bill Esser, PT, both physical therapists. Dr. Hobson is also an Oral Myofunctional Therapist and runs a breathing clinic. She is Rocabadotrained and lectures with Mariano Rocabado. I have utilized this Aqualizer® technique and have lectured on it for well over 10 years, but it has never been objectively evaluated by EBM protocols. The approach discussed avoided contaminating issues by evaluating patients on their very first visit for changes (correction) in hip height, per physical therapist protocols. A major issue of private practice clinical studies is that it would be unet","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125489775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Protocols for mobile dental photography with auxiliary lighting","authors":"Lohni Beverly","doi":"10.1080/08869634.2021.1876427","DOIUrl":"https://doi.org/10.1080/08869634.2021.1876427","url":null,"abstract":"Dental photography is one tricky thing to nail down properly. On the surface, it seems as easy as pointing a camera and taking the shot, but on the day when you’re finally preparing to document that one big case, you suddenly realize there’s far more involved in the process. This is a common trapping that many dentists and their staff fall into. Usually, this is met with an overcorrection, and before they know it, the office is inundated with expensive DSLR cameras, studio equipment, and complicated training for an uninterested staff and a dentist with very little time on his/her hands. This is where Protocols for Mobile Dental Photography with Auxiliary Lighting swoops in to help dental professionals understand that middle ground. This little book packs one punch of a crash course in not only dental photography, but photography in general. At 75.00 USD and around 120 pages, this book runs the gamut on why modern smart phones can be just as competitive, if not more efficient and convenient, than today’s professional equipment. From documenting a case for legal/ insurance reasons to artistic photography, this book provides a reference for getting that right shot. Each page is printed on high-quality glossy stock that is extensively illustrated with high-resolution images to help demonstrate its texts. I’m a Dental Assistant, but I have a previous degree as a Technologist, so I have become the go-to person to help document cases in my office. I’m often responsible for taking the needed images and getting them where they need to go. Mobile Dental Photography has convinced me to keep a dedicated, in-office-only smart phone for our case documenting, treatment planning, and even video-making. Knowing how to set up the shot, set the lighting and contrast, and use the proper technique to get the specific shots you want are just as important as having the camera itself. It doesn’t need to be a long and complicated process, and that is where this book comes in handy. It’s an easy read and a quick reference guide for a busy dental office. Mobile Dental Photography describes everything necessary to get professional intraoral and extraoral pictures. Considering that smartphones are the current day’s equivalent of a Swiss Army knife, the needed accessories are practically factored in as-is. This book has made me aware of the Smile Lite MDP device, which is probably the only other accessory needed for smart phone photography. It’s a small, handheld device that attaches to the camera itself and acts as a “mini studio,” complete with adjustable LED lighting and diffusers. I highly recommend Mobile Dental Photography as a nice reference and a quick little trainer to keep close-by in a dental office. As someone who has worked extensively in both fields of technology and dentistry, this book surprised me. It goes as in-depth as describing how light polarization works and how beneficial diffusers and proper contrast can be to each specific shot without overwhelming t","PeriodicalId":162405,"journal":{"name":"CRANIO®","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126394576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
