Plain English Summary
Background and study aims
Traditional orthodontic treatment planning practice has remained substantially unchanged for the past 20 years. Ulab Systems Inc. (“Ulab”) has developed a new digital treatment planning software that is significantly faster than the conventional treatment planning software on the market.
The purpose of this study is to gather data regarding the fit of the dental appliance(s) fabricated from the treatment plan generated from Ulab Systems, Inc. for treating crowding and spacing malocclusions (or imperfect positioning of teeth) in approximately 500 patients within the age range of 7-80. The study is evaluating the Ulab Systems, Inc. software and not the actual appliances that participants will be wearing. Only standard laboratory practices and approved materials will be used to create your appliances.
Who can participate?
Patients between 7 and 80 years old, with mild to moderate spacing or crowding of their teeth.
What does the study involve?
Gathering data about the fit of dental appliances created from images of a patients teeth using treatment planning software from uLab Systems, Inc. This data will be gathered during ususal treatment sessions.
What are the possible benefits and risks of participating?
The study may or may not help patients, however it may help patients in the future. There is no anticipation of any problems and the only discomfort would be minor tooth soreness that is normal during tooth movement.
Where is the study run from?
The study will be run by selected investigators at their local dental practices.
When is the study starting and how long is it expected to run for?
August 2019 to August 2021
Who is funding the study?
uLab Systems Inc., CA, USA
Who is the main contact?
Mr Scott Rehage
Evaluation of appliance fit and treatment outcome with use of the uLab system
It is expected that the appliances fabricated from the Ulab software will fit much better than conventional clear orthodontic appliances, mainly because Ulab is the only system that retains the actual digital gingival information. In turn, it is expected that appliances made from the digital data will fit the dentition of the patient much better.

Orthodontics - treating crowding and spacing malocclusions
Throughout the study successive dental appliances will be provided to gradually reposition patients teeth and the fit of the devices will be assessed by the investigator. Each office visit will take approximately one hour. This study will last as long as it takes to straighten patients teeth, approximately 6 months to 1 year or longer, and will include visits to the study doctor’s office approximately every 4 to 8 weeks. Dental appliance(s) fabricated from the STL file generated from the Ulab treatment planning software
The Ulab software will use a computer as a tool to assist in programming a series of sequential tooth movements to ensure appropriate, consistent forces on the patient’s teeth per investigators desired prescription. The investigator will program a treatment plan using the Ulab software, and determine how many steps will be required to achieve the desired treatment outcome. Once the treatment plan is programmed by the investigator, they can fabricate the appliances in their own office or via a third party orthodontic laboratory, using the standard dental laboratory practices and approved materials used by the dental industry.
Primary outcome measure
Percentage of dental appliance with acceptable fit (pass/fail), measured during patient consultations (approx. every 6 months).
Secondary outcome measures
1. Oral hygiene based on gender and age (poor/fair/good), measured during patient consultations (approx. every 6 months).
2. Patient compliance (poor/fair/good), measured during patient consultations (approx. every 6 months).
