Table 1 KD-MMS components
From: The university münster model surgery system for orthognathic surgery. Part II – KD-MMS
Component | Purpose and usage | Essential/ optional | |
|---|---|---|---|
| blue mounting plate | Replaces standard yellow SAM-mounting plate, first part of the double splint system.A SAM-P version is strongly recommended due to its greater vertical leeway. | Essential |
| red spacer plate | Completes double splint system.Mounted between blue plate and plaster model. When removed, permits for three-dimensional displacement of respective plaster model as neccessary for model surgery. | Essential |
| Rentention disk | Permit for magnetic attachment between plaster models and blue or red plates. | Essential |
| paper strips | Plain white paper strips are used to mark the model's sagittal position in relation to blue mounting plate. This is achieved by drawing vertical lines from plaster model to paper strip.The lines are positioned near following regions on each model:• midline• cuspids• first molars• retrotuberal areas | Essential |
| Drill and Anchor Bolts | Needed for mounting adjustment rods. | Essential when using rods |
| Adjustment rods | May be used to establish an adjustable connection between articulator and plaster models in preparation for intended three-dimensional movements.Also usable as an option to sticking wax when fitting plaster models in best fitting occlusion. | Essential unless triangular spacers are used |
| screw driver | To firmly insert rods into anchor bolts. | Essential when using rods |
| spanner | To tighten the nuts on the rods. | |
| hexagon socket screw key | To tighten the clamps connecting the adjustment rods. | Essential when using rods |
| triangular spacers | Triangular spacers of standardized thicknesses (1, 2, 3 and 5 mm) may be used to perform a three-dimensional displacement of the plaster model model surgery. | Essential unless rods are used |
| transparent spacer | In cases where no up or down movement of the maxilla is desired, this spacer with its fixed width of 8 mm assures a constant vertical while permittig movements in the sagittal and transversal plane. | Optional |
| incisal pin mounted gauge | Used to measure sagittal displacement. The incisors and/or the model base may be used as reference for measurements. | Optional |
