Book Description
Introduction: The purpose of this retrospective case-control study was to compare the treatment effectiveness and efficiency of the Invisalign system and conventional fixed appliances in treating orthodontic patients with mild to moderate malocclusion in a graduate orthodontic clinic. Methods: Using the peer assessment rating (PAR) index, we evaluated pretreatment and posttreatment records of 48 Invisalign patients and 48 fixed appliances patients. Those two groups of patients were controlled for general characteristics and initial severity of malocclusion. We analyzed treatment outcome, duration and improvement between the Invisalign and fixed appliances groups. Results: The average pretreatment PAR score (United Kingdom weighting) was 20.81 for Invisalign and 22.79 for fixed appliances (P = 1.0000). Posttreatment weighted PAR scores between Invisalign and fixed appliances were not statistically different (P = 0.7420). On average, Invisalign finished 5.7 months faster than fixed appliances (P = 0.0040). The weighted PAR score reduction with treatment was not statistically different between the Invisalign and fixed appliances groups (P = 0.4573). All cases in both groups had more than 30% reduction in PAR score. Logistic regression analysis indicates the odds of achieving "great improvement" in Invisalign group was only 0.329 times the odds of achieving “great improvement” in the fixed appliances group after controlling for age (P = 0.0150). Conclusions: Our data show that both Invisalign and fixed appliances were able to improve the malocclusion. Invisalign finished treatment faster than fixed appliances. However, it appears that Invisalign may not be as effective as fixed appliances in achieving "great improvement" in the malocclusion. This study might help clinicians to determine appropriate cases for Invisalign treatment.

Book Description
InvisalignRTM (Align Technologies Inc., Santa Clara, CA) has recently (1999) been offered correct malocclusions. Few studies have evaluated the capabilities of this appliance. Forty-four cases were studied for comparison of pre- and post treatment results. These cases were mainly mild to moderate Class I malocclusions. Cases were measured according to the PAR (Peer Assessment Rating) and Little's Irregularity Index. The Invisalign RTM appliance improved the overall PAR score (p
