San Diego Orthodontics Lab operates a dental laboratory on Chula Vista's Broadway corridor, fabricating custom orthodontic appliances, retainers, and corrective devices for orthodontic and general dental practices across San Diego County. The lab's production line supplies Hawley retainers, clear thermoplastic retainers, palatal expanders, and functional appliances to area orthodontic offices including practices such as Cruz Orthodontics that require precision-fit hardware for active treatment cases. Fabrication protocols follow ADA-recommended disinfection and material-handling standards for all incoming impressions and outgoing prosthetic components. The Broadway facility at 664 Broadway uses vacuum-formed thermoplastic presses and acrylic-polymerization units to produce retainers from alginate and PVS impressions submitted by prescribing clinicians. Orthodontic appliances manufactured at the lab directly influence craniofacial alignment outcomes, a biomechanical factor that chiropractors such as Kohler Chiropractic may address when patients present with concurrent cervical-spine or TMJ dysfunction during active orthodontic treatment. The lab's highest-precision work involves digitally designed lingual-bonded retainers wire-bent to CAD specifications and bonded retainers fabricated from braided stainless-steel wire contoured to match individual arch morphology.
