What are the complete requirements, contraindications, and specifications for Locator Fixed?
Locator Fixed has specific technical requirements that must be met for successful outcomes:
Minimum Requirements:
- Implants: 4 implants minimum required
- Angulation: Each implant must be within 20 degrees (only works with gold legacy abutment)
- VDO: 9-11mm per lab manual, 10-12mm preferred, 9mm workable but challenging
- Removability: Clinician removable, NOT patient removable
Contraindications:
- Insufficient implant sites: Less than 4 implants
- Inadequate VDO: Cases below 9mm are contraindicated
- Excessive angulation: Implants outside 20-degree range (requires gold abutment)
VDO Management for Challenging Cases:
- Limited VDO (9-10mm): May need to "steal" space from opposing arch if possible
- Natural dentition: Cannot steal space from the upper arch with natural teeth
- Patient expectations: Critical to set realistic expectations with limited VDO
- Case-by-case: Each overdenture conversion is unique, requiring individual assessment
System Differences from All-on-X:
- VDO requirement: 10-12mm vs 15mm+ for all-on-X
- AP spread: Less than all-on-X cases
- Cantilever ratios: 1:1 for non-bruxer, 1:0.5 for bruxer
- Patient acceptance: Removable patients typically don't care about cantilever limitations
