Open versus closed surgical exposure of canine teeth that are displaced in the roof of the mouth

Abstract

This review has revealed that currently, there is no evidence to support one surgical technique over the other in terms of dental health, aesthetics, economics and patient factors. Until high quality clinical trials with participants randomly allocated into the two treatment groups are conducted, methods of exposing canines will be left to the personal choice of the surgeon and orthodontist.

Periodontal health of palatally displaced canines treated with open or closed surgical technique: A multicenter, randomized controlled trial

“…10,11 A recent Cochrane systematic review found no robust evidence to support one surgical technique over the other. 12 The principal purpose of this trial was to explore any differences in the periodontal health between canines exposed using an Open versus a Closed surgical technique. Differences in periodontal health between canines that have had an operation (those that were palatally displaced and had been surgically exposed) versus the contralateral canines that have not undergone an operation (and can act as a control) were also examined.…”

No Difference in Surgical Outcomes Between Open and Closed Exposure of Palatally Displaced Maxillary Canines

“…6 Proponents of each technique claim certain advantages; however a recent Cochrane collaboration systematic review was unable to find any evidence to support the use of one technique over the other. 7 The purpose of this study was to determine if there are any differences in the outcomes between the Open and Closed surgical techniques for exposing a PDC. In this report the investigators tested the null hypothesis that there would be no difference in the surgical outcomes between the two techniques.…”

Esthetic judgments of palatally displaced canines 3 months postdebond after surgical exposure with either a closed or an open technique

“…A systematic review found no evidence of the superiority in terms of clinical attachment levels following treatment of one technique over the other. 2 A recent randomized controlled trial has confirmed this. 3 One outcome that has received limited investigation is the esthetic appearance of the PDC, following surgical exposure and alignment D A 4 obtained the esthetic judgments of orthodontists and patients concerning displaced canines that had been exposed using a closed surgical technique and orthodontically aligned.…”
