70
Model No. 539. Male. Age 11 n/12ths.
Diagnosis: —
Class i. No room for | 3. Lower fronts imbricated.
Report of the Royal Dental Hospital Orthodontic Specialist:-
We have had X-rays taken of the upper canine region left and
right. Both areas present considerable difficulty.
On the right there is not enough room without extraction or
expansion of the arch, and much too much room will be gained if
the first premolar is extracted.
On the left the canine tooth is apparently lying at an obtuse
angle to the lateral, and even if the first premolar be removed, I
have considerable doubt as to whether the canine will travel
sufficiently far to take up its correct alignment in the arch.
On the whole I would advise no treatment at the moment, but
would be glad to see the boy in about 6 months' time.

Model No. 598. Male. 7 8/12ths.
Diagnosis:—
Linguoversion of right upper two.
Report of the Royal Dental Hospital Orthodontic Specialist —
In my opinion the crowded condition of this mouth can be
best treated at the moment by the extraction of the two lower temporary
canines. The right lower lateral incisor will probably be
moved into the arch by the tongue. Later on the extraction of
the four first premolars will be necessary. X-rays show that all
second premolars are present.
Ultimate treatment usually depends on the amount of growth
that takes place, and for this reason I should like to see this case
again in 12 months' time. It is just possible that I shall advise the
extraction of the lower incisor later on, but at present it is impossible
to decide which will be the best course to take.
It is extremely important to remember that a too early extraction
of permanent teeth is contra-indicated as it interferes with the
normal bone growth.
