Conclusion: Without treatment, a short arch length
will only get worse.
6% HL; preopercular pores 5-13; ocular-side suborbital pores 13-38; blind-side suborbital pores 6-20; lateral line with a high arch, 6-8 scale rows high over the pectoral fin, arch length
about three times its depth, length 26.
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.
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.
Changing in the arch length
following pre- mature loss of deciduous molars.
Arch width arch length
and tooth size in young males Angle Orthod.
Hnat et al24 also reported that when mandibular tooth size increases, the mandibular arch length
and arch width also increase to accommodate the large sized dentition.
A properly designed fixed space maintainer not only preserves arch length
but also reduces the psychological trauma, speech problems and prevents the development of tongue thrusting habits.
The authors found Men had significantly longer arch length
and smaller premaxillary divergence than women.
Intercanine width, intermolar width and arch length
are essential for diagnosis and treatment planning and are closely related factors in orthodontics.
Other reported favorable effect after third molar extraction is the significant amount of buccal movement of second molar due to the gain in posterior segment arch length
1 An increasing number of parents are concerned about the possibility of future dental crowdprimary canines, maxillary and mandibular dental arch length
as factors in the early mixed dentition that could possibly be indicators for crowding.
