the abrasive particles are secured to one side of a flexible backing with an adhesive; used with mandrels, use diminishing abrasive agents until achieved a smooth shiny mirror like appearance, after 24-48 hour placement use rubber cusps or softened bristle brushes, aluminum oxide polishing paste, begin with least abrasive - do not use ultrasonic scaler or air-polishing, special porcelain polishing paste, sub micron aluminum oxide for gold, if stain is not due to microleakafe treat the same as composite, not all teeth - should not exceed more than 30 secondary - light sweeping motion, indicated that the abrasive particles do not exceed the maximum acceptable abrasiveness, most important/critical polishing with prophylaxis jet, commercial products should be non-toxic, non-abrasive and non detrimental to the prosthesis being cleaned - do not use toothpaste, - eliminates the need for an injected anesthetic - - completed more quickly, pressurized stream or non-toxic aluminum oxide powder is used to remove small amounts of decay from tooth's outer enamel layer, always educate clients on the dietary staining.

The 3rd edition of ‘Dental Materials (Principles and Applications)’ by Zohaib Khurshid and his co-editor is an up-to-date information manual in the field of dental material science. orthodontic wires, problems seen clinically with ceramic-alloy crowns are usually associated with fracture within the porcelain leaving the metal exposed, all surfaces of the metal is covered with porcelain, the occlusal surface is in metal especially for clients who grind their teeth, just a line of metal seeing on the cervical, - solder fixer space maintainer components, - composed of wrought wire that has been twisted to produced multiple cutting edges, - orthodontic brackets and bands are bonded or cemented to teeth, - fixed lingual retainer helps maintain the position of the teeth after orthodontic treatment, made from a wax or resin pattern made directly on the tooth or in the dental lab, most common used posts, available as parallel or tapered, metal or non-metal, passive or active, - replace one or more single units as individual crowns, placed under the periosteum and rest on the bone, most common in the mandible, close adaptation helps to develop a biological seal that prevents MOs from invading the tissues - need good oral hygiene, in emergency situation if the client presents fractured tooth, cleans forms which are filled with acrylic or composite which match tooth shade and then inserted onto prepared tooth, provisional is fabricated directly on the tooth, template is made on the study model, fabrication usually done of model, involves restoration or replacement of missing tissues or teeth, ideal option for repairing decayed or damaged back teeth, may be made of porcelain, resins, or dental ceramic materials, stronger than all-ceramic versions and more aesthetically pleasing than those made of metal, procedure that is required in order to rebuild and strengthen a tooth that had root canal treatment, advanced metallurgic technology of producing high-hold metal substances for crowns and bridges, are preferred method to replace single or multiple missing teeth, even partial or full denture - titanium artificial root is place din the jawbone and allowed to join (integrate) with bone over 3-6 months, a fixed bridge refers to a prosthesis that will span the area of a missing tooth, known as pontic, the procedure involved the preparation of two or more abutment teeth, removable dental appliance that replaced multiple missing teeth, similar to a filling and lies inside the cusp tips of a tooth, made of a stronger, natural-looking material, such as porcelain, synthetic polymers used in dentistry - denture bases, denture teeth, relining a repair of prosthesis, etc, added acrylic resin colour to resemble oral mucosa, added to keep acrylic from being tooth transparent, helps prevent surface cracks, improves resistance to structural fatigue, additional of plasticizers, rubbers and fillers to change physical and mechanical properties, strengthen resin or change its optical properties, harder, stronger and less porous and have less than 1% residual monomer, weaker, softer, more porous and less colour stable, polymers undergo shrinkage during polymerization process, free ionomer (MMA) can cause tissue irritation and inflammation, - biting force with dentures is 20% of that with natural teeth, will always feels looser because there isn't a large surface area for rest and support (hard palate), extra rod is common as the site heals after extraction, constructed from the same metals as the trays, used for construction of custom trays & record bases, if totient has accumulated a lot of calculus around the surfaces of the denture, before returning it to the patient be sure to clean it in placing it in a denture cleaning solution (denture and solution goes in a bag and is placed in the ultrasonic cleanser), the acrylic resin prosthesis can absorb water and are sensitive to water loss so make sure to instruct patient to keep it wet during some periods of storage, need to be cleaned daily, more than once if possible, will have metal clasps that need to be cleaned gently to prevent distorting, - fixes looseness that occurs as the bony ridges resorb and the gums shrink, one term denture relines can be made with either a hard setting materials or a soft, flexible one, soft liners may be used for short term or long term us, if a client has chronic soreness with a hard base because o a thin mucosa or sharp body spicules a soft base may be used, last 1-3 years, made from silicone rubber or acrylics such as ethyl or methyl methacrylate, - placed at chair side, powder which is composed of poly, mix powder and liquid according to manufacture directions, most common, used to fill the spaces when dentures become too loose, can be purchased at drugstore, overtime these materials can stiffen and cause damage to the tissue, - mostly widely used because resilient and do not stress the underlying ridges, - improved properties compared with a acrylic, teeth can resemble a single shade or the client can have lighter and darker restorations, - specialized aspect or prosthodontics practice, - prepare of partial denture with metal framework is more complex depending on location of break, light-cured deminthacrylate is an acrylic resin that contains a chemical activated by light in the blue wave range, an accelerator, inorganic fillers and pigments to stimulate tissue colours, the prosthesis is prepared the same way as for chemical-cured materials, except a different liquid is pained on the fractured pieces before the repair material is applied.
