The Design of Maxillary Occlusal Guards in the Treatment of Acute TMJ Dysfunction Paul D. &huller Quintessence Internat. 12:1295-1301, 1981
Different philosophies among researchers, teachers, and practitioners concerning TMJ problems and their etiology have led to many diverse treatments. One form that has been used with considerable success for acute problems is the so-called night guard, night splint, occlusal splint, bite plate, or bite guard. A well-made occlusal splint is usually successful because it provides interarch occlusal stability and eliminates occlusal interferences. This is particularly true for nocturnal bruxism and clenching. EMG studies indicate that the silent period of masticatory muscles is reduced following splint insertion, followed by a decrease in muscle tone and relief of symptoms. The appliance, usually placed on the maxillary arch, opens the interarch relationship with the acrylic occlusal cover and increases the vertical dimension. The patient must wear the appliance for 24 hours a day. Relief is often immediate, but appliance wear is usually for 2 to 3 months. During this time, adjunctive dental therapy may be performed. The article illustrates several types of splints used by the author and stresses that, while relief of symptoms may be dramatic, the splint is only the initial phase of a combined and sometimes complex treatment involving reconstruction, orthodontics, psychological counseling, and drug therapy.
orthodontics suggest that there may be a relationship between personality dimensions and facial structure. Twenty subjects with long, angular faces and twenty subjects with short, square faces were selected on the basis of a cephalometric study. All subjects completed a biographical data sheet and a comprehensive Personality Factor Questionnaire. Subjects with long, angular faces were found to be more responsive, assertive, and genuine than subjects with short, square faces, who were more restrained, conforming, and shrewd. The results of this study were compared with somatotype literature linking body size and shape with personality traits. The article discusses the role of genetic factors underlying facial structure and personality attributes, the development of behavior patterns based on social stereotypes about facial shape, and the effects of postural sets on facial form during maturation. The authors conclude that, on the basis of their results, they would hypothesize that inhibited, socially conforming persons would have high levels of resting EMG activity and tonus in the temporal and masseter muscles which would pull the jaws together and decrease face height during maturation, whereas expressive, socially assertive individuals would have lower levels of activity in these muscles but higher levels in the depressor and lateral pterygoid muscles, which would pull the jaws apart and increase facial length. Clearly, there is a need for further experimental and developmental work in this area. T. M. Graber

Am. .I Orthod. Jmr 1982
and abstract3
Chapters by Roberts and associates, Yoshikawa, Diaz, Faber, Nanda, Bert, Glassman, Norton, Legan, Melsen, Shapiro and Kokich, Hickory, and the editor cover a variety of special practice concerns. Cellular response, biomechanical principles, treatment objectives and planning, appliance design, cross-bite and overbite problems, root-angulation problems, space closure, tooth transplantation, periodontal considerations, orthognathic surgery, removable appliances, retention, and nutritional considerations are covered well, considering the space restraints. The book is a fresh approach to these time-honored subjects and provides most interesting reading for the orthodontic specialist.
trated with superb color drawings and photographs on a grade of paper usually seen only in the best of the annual publications of our more affluent corporate giants. The subject matter is carefully chosen and is tops in the fields of periodontics and restorative dentistry. Teachers in these subjects can have a field day making slides of the illustrations for their students. Since orthodontic specialists should know the current state of the art in other dental specialties, this journal offers a most palatable vehicle. You are urged to pick up a copy from the dental library and experience the same scientific gratification that the reviewer has had. T. M. Graber

Dental Management of the Child Patient Hannelore T. Loevy Chicago, Berlin, and Rio de Janeiro, 1981, Quintessence Publishing Company, Inc. 310 pages, illustrated, index
Careful examination, appropriate treatment, and sound preventive measures are the three pillars on which this volume rests. While common pedodontic problems are reviewed, special attention is given to developmental abnormalities of the head and jaw, trauma, prevention, and what the author calls “tooth and tongue abnormalities. ” Also covered are pain, anxiety, infection control, and proper use of dental materials. The book is addressed to the practitioner as well as the dental student. The production details for this book are truly outstanding. The large number of excellent colored illustrations, the fine quality of paper, and the readable type style are seldom matched today in any book in any field. They make up for some of the deficiencies in the chapters on growth and development, cephalometrics, and interceptive orthodontics, and in the selected references after each chapter. T. M. Graber

The authors have been working with the Garliner method of myofunctional therapy for 5 years and had previously studied measurement techniques on 254 adults (1980). They point up the importance of this adjunctive therapy with the use of functional appliances. In the present study, lip strength measurements, as described by Garliner, were recorded for 338 children under orthodontic treatment. The results showed that there was no significant difference between the lip strength measurements in open-bite and other types of malocclusions, as had been claimed. The conclusion is that the measurements suggested by Garliner must be questioned. They may be of use in motivating patients to pursue myofunctional therapy during orthodontic treatment, but they are not suitable for scientific research. T. M. Graber
