Study Notes
- Record base plays a crucial role in denture fabrication, ensuring strength, rigidity, and accuracy.
- Ideal record base should not move on the cast, have smooth, rounded, well-polished borders, and palate thickness resembling finished dentures.
- Mostly used materials for record bases are cold self-cure acrylic resin and light cure resin.
- Fabrication of record bases and wax rims involves various instruments and materials like baseplate wax, wax spatula, Hanau torch, cloth polishing wheel, large camel’s hair brush, red handle knife, celluloid mm rule, Bunsen burner, and autopolymerizing acrylic resin.
- Procedures for record base fabrication include blocking out master casts, adding resin, and polymerization.
- For maxillary record base fabrication, the sprinkle-on technique is used to add resin, and the ridge crest is reinforced to prevent slumping.
- For mandibular record base fabrication, the ridge portion must be reinforced and thin to facilitate tooth placement.
- Record base preparation involves soaking the polymerized record base and casts in hot water to soften the block-out wax and gently removing the record bases from the master cast.
- Maxilla areas requiring modification on unfinished record bases include trimming excess flash and thinning the ridge lap portion.
- Completed record bases should have a consistent thickness, no porosity or voids, and smooth, rounded flanges.
- Occlusion rims are occluding surfaces constructed on record bases or permanent denture bases for jaw relation recording and tooth arrangement.
- For wax occlusion rims, they are used for face bow transfer records, developing contours of the lips and cheeks, and measuring the vertical dimension of occlusion.
- Maxillary wax rim fabrication involves heating a sheet of baseplate wax, forming the occlusal aspect of the rim, and contouring the buccal and labial contours.
- Mandibular wax rim fabrication involves centering the rim over the crest of the ridge and ensuring lingual contours do not impinge on tongue space.
- Determine incisor position and occlusal plane using a "Fox" occlusal plane and verify the proper level and angulation of the occlusal plane.
- Fabricate maxillary and mandibular wax rims using a hot plate (occlusal plane former) and various instruments like a wax spatula and paper towel.
