Drag along the arch, or use the arrow keys. Hold Shift for a larger keyboard step.

Sites stay in order, and insert colors update from the visible arch and the support-zone grouping model. The passive brackets each measure A/P spread from that displayed side's most anterior site to that side's most posterior site. The material-specific maximum is projected independently from each posterior site. Equivalent left and right measurements share one combined bracket; asymmetric measurements stay separate. Left and right refer to the displayed view, not patient laterality. For 1× materials, the lighter coral line also shows the 0.5× bruxism or clenching maximum. A downward continuation mark means that maximum is beyond the displayed model. Sites remain draggable along the arch while maintaining order, visible spacing, and the fixture's distal ends; guidance never changes their positions. The peach palate is presentation-only. Fixed ≤2 mm rules use a logical 4.75 mm insert diameter, measure 2 mm beyond the insert edge, and compare that visible limit with the stable midpoint of the slanted distal fixture closure. A/P-factor guidance retains its separate clinical boundary. The palate thickness is a schematic of the selected material's recommended minimum around each housing; it is not a measurement of the patient's prosthesis. Conventional resin with a metal substructure is the default. For 1× materials, bruxism or clenching uses a 0.5× maximum. Manufacturer maximums are not targets. The not-recommended status uses conservative planner support adequacy, layout distribution, and posterior-cantilever thresholds; it is not a manufacturer contraindication or a patient eligibility determination. Confirm anatomy, measurements, material, reinforcement, parafunction, and prosthesis design before use.
