FREQUENTLY ASKED QUESTIONS - Orthodontics
What clear aligner systems are available for general dentists?
Several clear aligner systems are designed for general practitioners, including ClearCorrect, SureSmile, Clarity, Smilers, uLab, and Invisalign. Key differences include case submission workflow, refinement policies, open vs. closed scanner compatibility, and pricing structure. DPS evaluates clear aligner systems on workflow ease, patient acceptance, and clinical outcomes.
What is the difference between a retainer and a clear aligner?
Retainers maintain tooth position after orthodontic treatment and are designed for long-term wear; clear aligners actively move teeth through a series of progressively repositioned trays. Some clear aligner systems — including ClearCorrect — can fabricate retainers directly from prior case data without new impressions.
What trim line design produces the best clear aligner retention?
A straight trim line cut 2 mm above the gingival zenith delivers significantly more retention than a scalloped margin. Research cited in DPS editorial content shows this cut provides four times the retention of a scalloped margin — a clinically relevant finding for practices managing their own aligner trimming.
What orthodontic accessories does a general dentist need to offer clear aligner therapy?
Core accessories include an intraoral scanner for digital impressions, aligner seating tools, articulating paper for occlusal adjustment, interproximal reduction strips, and a bonding kit for attachments. Some practices also stock thermoforming pliers for aligner adjustments and overcorrection.
How do DPS clinician evaluators rate orthodontic products?
Independent panels of practicing dentists use products in their own offices for approximately 4 weeks, rating on clinical criteria including fit accuracy, patient compliance, workflow integration, and outcome predictability. Products scoring 4.3 or above earn the DPS Best Product designation.
