The effects of Fränkel II treatment on arch width and arch perimeter
American Journal of Orthodontics and Dentofacial Orthopedics, 1987Changes in dental arch width and total arch perimeter in 24 Class II, Division 1 patients treated with the Fränkel II appliance were compared with changes in an untreated control group. Measurements were made on pretreatment and posttreatment plaster casts at three points on each of four maxillary and four mandibular teeth.

A study of the literature reveals a variety of opinions on the potential for change in arch dimensions. The variations in sample sizes, treatment mechanics, and retention regimens may obscure relevant findings. These articles confirm some common findings, and a number of clinical cases are presented to illustrate these trends.

Relationships between dental arch widths and widths of the face and head
American Journal of Orthodontics, 1951Abstract This paper treats three problems: the relationship between maxillary arch width and width of the upper face, the relationship between maxillary arch width and width of the head, and the relationship between mandibular arch width and width of the lower face. Original findings are reported on a sample of North American white children residing

Arch width after extraction and nonextraction treatment
American Journal of Orthodontics and Dentofacial Orthopedics, 2003An undocumented criticism of extraction treatment is that it results in narrower dental arches when compared with nonextraction therapy. Anterior and posterior arch widths of the maxillary and mandibular arches of 25 patients treated by 4 first-premolar extraction and 25 patients treated without extractions were measured on posttreatment study models ...

Arch width, canine position, and mandibular retention
American Journal of Orthodontics, 1973Abstract The canine-to-canine retainer technique has been used in the construction of an infinite number of such retainers. The chair time required is minimal, for the technique consists merely of making two canine bands and a plaster cast from a sectional compound impression.

A study of occlusion and arch widths in families
American Journal of Orthodontics, 1980It is often claimed that occlusal variation ("malocclusion") is under strong genetic control. This study of a large age-standardized series of families (parents and offspring) shows that the genetic contribution to occlusal variation is quite low. On average, only about 10 percent of the variation in overjet, overbite, crowding, tooth rotations, and ...

Deciduous dental arch widths and widths of the face in early childhood
American Journal of Orthodontics, 1951Abstract The data for this investigation were obtained from one hundred thirty white children (67 males, 63 females) who are enrolled in the Facial Growth Study being conducted at the University of Iowa. Approximately 95 per cent of the parents were of northwest European ancestry, and resided in or near Iowa City.

Morphologic evidence of muscle influence on dental arch width
American Journal of Orthodontics, 1979Tests on hypotheses to explain changes in arch width during correction of distoclusion with the activator appliance used in this study showed that statistically significant increases occurred in both maxillary and mandibular arch widths during treatment. The increase was substantially larger in the maxilla than in the mandible. The arch width showed no

The phenomenon of decreased mandibular arch width in opening movements
The Journal of Prosthetic Dentistry, 1967Abstract Recent measurements indicate that deformation of the mandible occurs during opening movements. This important phenomenon is of considerable clinical significance. Further investigation, with a measuring apparatus rigidly attached to the teeth and possibly using strain gauges attached to fixed restorations, is indicated.

Predicting first molar width using virtual models of dental arches
Clinical Anatomy, 2007AbstractIn dentistry, large regions of dentition often are restored with minimal information about the original anatomy. The ability to predict missing anatomy from existing anatomy would aid such restorations. This study investigated the relationship between first molar mesial‐distal width and arch shape using newly defined reference points and three ...
