However, it was observed that there was no information about cephalometric measurements and arch lengths in these studies.
Changes in the maxillary and mandibular tooth size - arch length relationship from early adolescence to early adulthood.
Conclusion: Without treatment, a short arch length will only get worse.
A three-dimensional anatomic maxillary model was constructed with photoelastic materials from a pretreatment clinical model of an early mixed dentition with deficient arch length. Different photoelastic materials were used to represent the teeth (PLM-1, Photoelastic Division, Measurements Group, Raleigh, NC) and bony structure of the midface (Solithane-C113-300, Uniroyal Chemical Co., Inc., Middlebury, CT).
4mm) and that when the accumulated mass of 20 permanent teeth is 140mm or more, the clinician may consider treatment with extractions.13 These findings and the results of our study may suggest that beyond the arch length analysis, the sum of mesio-distal widths of the teeth and the length of apical base should be considered in the formulation of the orthodontic treatment plan, especially in borderline cases where there may be an element of doubt about extraction of permanent teeth.
Leveling the curve of Spee: its effectson the mandibular arch length. J Pract Orthod 1969; 3:26-41.
With the help of arch length and width measurements an orthodontist can predict the functional and aesthetic outcome of a particular case.
A concordance was found between the sizes of the deciduous second molars with the size of the permanent first molars, this might be helpfulin prediction for arch length discrepancy which may result for possible crowding and occlusal relation in the permanent dentition.
Dental anomalies in tooth number, shape, structure, and position may lead to problems in arch length and occlusion.
Some common sequelae of canine impaction are: (i) Labial or lingual malpositioning of the impacted tooth (ii) Migration of the neighboring teeth and loss of arch length (iii) Ex- ternal root resorption of the impacted tooth as well as the neighboring teeth (iv) Infection particularly with partial eruption resulting in pain and trismus and (v) Referred pain.11
