What are the maintenance requirements, tooling needs, and component availability for Locator Fixed?

Locator Fixed requires specific maintenance protocols and specialized equipment:

Maintenance Schedule:

  • First year: Every 6 months (twice per year)
  • After the first year: Once per year minimum
  • Bare minimum: GP visits twice yearly for oral cancer screening, OHI, prosthesis evaluation, and implant assessment

System Technology Differences: Removable System:

  • Insert material: Nylon (squishy, soft)
  • Function: Daily in/out use, multiple wear cycles
  • Movement: Pivoting and slight movement allowed

Locator Fixed System:

  • Insert material: PEAK (rigid material)
  • Manufacturing: Housing and insert made on the same machine for a precise fit
  • Movement: No pivoting, minimal movement
  • Critical limitation: PEAK inserts distort when removed and never regain the same retention - must replace every removal

 Required Tooling:

  • Seating/removal tool: Handle with seat and removal ends (similar to crown and bridge removers)
  • Function: The Removal end goes underneath the cantilever
  • Sound/vibration: Makes noise, but isn't as aggressive as it seems
  • New core tool: Required for PEAK inserts (old core tools are too thin, insufficient stability)
  • Ownership: Clinician purchases and owns (needed for ongoing maintenance)

Component Availability:

  • Current status: Lab doesn't carry Locator Fixed inserts, housings, tooling
  • Sourcing: All components must come directly from ZEST
  • Coordination: Contact ZEST representative for component delivery
  • Future: Direct partnership being developed between ZEST and lab
  • Removable components: Currently available through Preat (third-party vendor). With this said, Fixed components and angled locators are not offered through some distributors.

Workflow Options:

  • Lab processing: Available with ZEST component coordination
  • Office processing: Available using the pickup method
  • Cement selection: Must match prosthetic material (contact lab for guidance)
