Abstract

A study model has been designed to evaluate the effectiveness of a new fenestration corticotomy procedure in two non-human primates Macaca fasicularis.

The objective of this study was to evaluate the efficacy of a new conservative corticotomy procedure to facilitate dental translation using fenestrations. This pilot study compared treatment and control quadrants of each individual animal's maxilla and mandible with both having the same retraction appliance and force on the 2nd premolar following extraction of the 1st molars. The null hypothesis stated that there was no significant statistical difference between the new conservative corticotomy procedure (fenestrations) when compared with the control (no corticotomy).

The results indicated that the mandibular corticotomised 2nd premolars moved collectively 34% further than the noncorticotomised mandibular 2nd premolars. The maxillary treatment premolars moved less than the maxillary control. However for one of the animals, there was much more maxillary anchorage loss on treatment 2nd and 3rd molars than control. The emphasis of a necessity of anchorage preparation in the maxillary arch is essential when performing corticotomy procedures.

This being a pilot study, future animal and clinical trials could be set up to further evaluate and develop the fenestration-corticotomy technique.
