All 19 patients had severe maxillary transverse deficiency, deep palate and bilateral posterior cross bite
These differences include adenoidal face, narrower maxilla, deeper palatal height, retrusive mandible, deficient chin, and long lower face, cross bites
, increased overjet, and oral breathing.
Once the oral hygiene was improved an upper alginate impression was taken to construct a quadhelix appliance in the dental laboratory to correct the unilateral cross bite
and to gain more space for the impacted UR1 (Fig.
In the present study, no investigation of the exact cause of an individual nasal resistance was carried out; neither the severity of nasal resistance was assessed, as we believe that neither the severity of adenoids obstructive size or cause of obstruction is a risk factor in development of class II malocclusion, presence of anterior open bite and or posterior cross bite
Each individual was assessed visually with a millimetre ruler for the presence of different occlusal traits (normal occlusion Class 1 Class 2 division 1 Class 2 division 2 and Class3 maloc- clusion) overjet (OJ) overbite (OB) crowding midline diastema and cross bite
5%) had a relapse, maxillary right lateral incisor went back into cross bite
(fig 5), though to a lesser extent.
A unilateral or bilateral cross bite
can also lead to TMJ dysfunction syndrome, which can cause a constant, dull headache, although the pain may be referred to shoulder and neck and also to the arms.
An unusual case of multiple talon cusps affecting the maxillary central incisors and the canines bilaterally together with other dental abnormalities viz dens invaginatus affecting the maxillary lateral incisors, microdontia, short roots, reduced alveolar bone height, dilaceration of the described posterior teeth, anterior open bite and bilateral posterior cross bite
in a 35 year old male.
5% for unilateral and 25% for bilateral posterior cross bite
In 2004, school children and adolescents were studied for the presence of posterior cross bites
Malocclusion was defined as presence of open bite, cross bites
, space deficiency (closed contacts among incisors), as well as abnormal canine and molar relationship.
