Completing the tweed triangle involved in preparing my book was quite a task, and I'm just recovering my health and have only begun to line up more of my former patients tweed triangle complete records.

I hope in the next three years I will be able to complete the project. My immediate ambition is to be able to have nonextraction cases lined up on one bench and extraction cases on another, and to be able to suggest that anyone interested can examine the display and draw their own conclusions.


And I am sure one will find the extraction cases 20, tweed triangle, and tweed triangle years later are much nicer than the nonextraction cases. Just to go back to the topic of stability. What is your opinion about the influence or influences of the muscles and musculature on the stability of a treated malocclusion?

I feel it is very important to the orthodontist.

Determination of Tweed's cephalometric norms in Bengali population

So much so, that I refer each one of my patients that comes to tweed triangle for an examination to the therapist for the correction of any abnormal tweed triangle, lip, sucking, or swallowing habits--for to me, unless such habits are corrected, the face cannot develop normally and as beautifully as would be the case if the individual were free from the adverse effects of these influences.

How about other than tongue and lip--the muscles of mastication and some of the other musculature that's hidden?

Do you think that these influence the stability of the treated malocclusion? And I could carry tweed triangle just a step further--do the orthodontists alter any of their characteristics or change tweed triangle balance? Some questions I can't answer.

Obviously, perversion of musculature has a bearing on the success of orthodontic therapy. One observes individuals who have had polio that has affected the musculature of one side of the face, with serious impairment of function.

I would not attempt to answer the question of how much one can change musculature as a result of orthodontic treatment procedures.

Tweed triangle

May we discuss a few specific problems that trouble so many tweed triangle us practitioners? For example, if you had completed a diagnosis with models, x-rays, photographs, cephalometrics, or any other diagnostic tools you wish, and you found the patient in the mixed dentition, Class I molar relationship with a low FMA reading and crowded upper and lower incisors, what would you do?

Would you start serial extraction procedures? Sid, first of all I tweed triangle have to have some more information. What is the arch-length deficiency?


Is it 1mm or is it 10mm? Well, let's tweed triangle that it is somewhere in between, somewhere around 5 or 6mm where there is definite crowding and there seems to be a definite imbalance tweed triangle basal bone and tooth structure.


If tweed triangle tooth-basal bone discrepancy is 6mm or more, I certainly would begin a serial extraction procedure and eventually remove all four first premolars prior to any active treatment. Malocclusion resulting tweed triangle thumb-sucking. Observe the beginning gum recession of the left mandibular central incisor.
