Abstract

This study was designed to (1) demonstrate the dimensional changes resulting from opening the suture, (2) test the stability of the repaired suture two months following the removal of the retentive appliance, and (3) demonstrate new bone growth in the opened suture by the use of Tetracycline staining. The animal chosen was the Macaca mulatta monkey.

Intact skulls, sectioned skulls and dental casts were measured following the experiment. The skulls were mounted in clear plastic and sectioned antero-posteriorly for the purposes of study and measurements. The following changes were noted as a result of this experiment:

  1. The floor of the nose was widened and lowered.
  2. The buccal teeth were carried outward and slightly upward.
  3. There was a broadening of the external nasal area giving a pug nose effect.
  4. A pathologic crossbite of the upper buccal teeth resulted from the widening of the maxillary bones.
  5. A large area of new bone filled into the separated suture which fluoresced under ultra-violet light.
  6. The new bone was considered stable.

Because of the many changes resulting from the treatment, it is imperative the operator be aware of the impact this treatment can exert upon the facial morphology.
