Yr hyn y mae angen i chi ei wybod am orffen a chaboli

Opsiynau sydd ar gael:

Surface Coated: The most classic option for finishing and polishing is the "sand paper" style, similar to the classic Moore's discs. Moving past paper, these can be attached to more sturdy materials such as plastics or metals to extend the life of the abrasive. These systems can be limited by the eventual loss of the abrasive from the surface of the material which can decrease their effectiveness.

Deunyddiau Trwytho: Brushes, cones, and points can all be impregnated with abrasives to allow for various levels of polishing. These tend to be useful for the final steps of polishing rather than coarse adjustments. Similar to stones, these materials usually have the abrasives throughout the material.

Cerrig: The best benefit to using a stone material to polish dental restorations is the grit is constant throughout its life of polishing. Many stones also come impregnated with materials such as silicon carbide to help get the job done. These can be used on metals, composites and porcelains.

Opsiynau carbid: Burs transition from coarse to fine by increasing the number of flutes on the bur. Consider the shape of the bur to adapt to the largest possible area to avoid cross strokes on the material.

Burs Diemwnt: Similar to increasing the flutes of a carbide bur, these polishers go from coarse diamonds to increasingly fine surface coatings. These are especially useful for initial shaping and coarse adjustments to your restoration.

Shapes: All of the previously noted finishing and polishing instrument types are available in a range of shapes, from points, to cups, to disgiau, olwynion a mwy. Ystyriwch y math a lleoliad y weithdrefn yr ydych yn ei wneud. Er enghraifft, a yw hwn yn atgyweiriad endoriadol, yn gyfansawdd dwyieithog, neu'n lenwad achudd yn ôl? Dewiswch y siâp a fydd yn ffitio ac yn addasu'n llwyr i'r wyneb rydych chi'n ei sgleinio. Mae rhai systemau yn defnyddio gwahanol siapiau brwsh a all fod yn fwy addasadwy yn gyffredinol fel nad oes rhaid i chi newid mor aml.

Gloywi Pastau: To achieve a final high gloss finish, polishing pastes make a great impact. They are mixed with abrasives such as diamond particles, and can be used with cups or brushes.

Allweddi Llwyddiant:

While this might sound obvious, it is incredibly important to understand the correct sequence to use when going from coarse to fine. It may be appropriate at times to jump in mid-sequence depending on how much finishing and polishing is required. There also are -cam sengl polishing systems designed to do the job with just one polisher.

Y prif beth i'w osgoi yw creu gorffeniad sglein dros arwyneb anwastad. Oherwydd hyn, mae hefyd yn bwysig deall y deunydd rydych chi'n gweithio arno, a beth sy'n gweithio orau yn y sefyllfaoedd hynny.

If you are ever unsure about how to finish a particular material, there is perhaps no better resource than your lab technician. Schedule a time to head over there for a short tutorial. There is a reason why the restorations always look so fantastic when they come from the lab.
