Over the past decades there has been a huge barrage of cementation products available to dentists. Also specializing for use in different fields of dentistry; restorative,orthodontic,endodontic, surgery, implant,etc. Thus making the task of choosing which type of cement to use, how to use it, AND for which indication very confusing. In recent years there has been an influx of prosthetic restorative materials to choose from. Choices ranging from traditional PFM, All Ceramic, Zirconia, Indirect Composite resin and CAD-CAM milled products have become the standard options. Todays dental practice can vary from a single operator working from one chair in Nanaimo to a multi associate group practice in Zürich. All have the expectation of receiving the highest quality in products to give to their patients. With so many different types of procedures and clinical decisions to be made, clearly one type of cement and/or luting product cannot satisfy all situations. Therefore it is imperative that dentists have many types of cements available in their practice. We at Kerr hope you will enjoy reading our guide. We strive to deliver to you the highest quality in all our products that you use everyday. Your practice is our inspiration! Your practice is our inspiration.™ 2 Inspired by... “Ideally, dental cements should adhere to tooth structure as well as restorative materials. They should exhibit the following characteristics: • resist functional forces • be insoluble in oral fluids • be effective while maintaining a low film thickness • be compatible with pulp tissue • exhibit anticariogenic properties • be easy to manipulate and clean up To date no one cement has achieved all of these properties together, but the current offering of resin cements demonstrate high strength, relatively low solubility, self or dual cure functions; reduced or eliminated post-op sensitivity, and relative ease of handling. Kerr dental cements have been a part of my daily practice for over 25 years” Dr. Isaac Novak Cementation in Dentistry The Prosthodontic Procedure Guide to Cementation All you need is Kerr 3 STEP PRODUCT KERR PRODUCTS Impression for study models Impression Material Take 1 Alginate Alginot FS Take 1 Alginate Take 1 Alginate AlgiNot FS AlgiNot FS Pour up of models Stones and Plasters Snow White Plaster type 2 Orthodontic Model Mix Stone Hydrocal Denture Model Stone Impression Material Impression for Temporization AlgiNot FS Take1 Alginate Your practice is our inspiration.™ 4 STEP PRODUCT KERR PRODUCTS Burs Tooth Preparation Final Impression Impression Material Beavers Carbide Jet Burs BlueWhite Diamond Burs Beavers Carbide Jet Bur BlueWhite Diamond Bur *LB = Light Body, RB = Regular Body, Med/Mon = Medium/Monophase, HB = Heavy Body Options: Delivery, viscosity and set time Unidose® Kerr’s unique Unidose delivery offers dual benefits: targeted syringe delivery and the elimination of cross- contamination concerns Cartridge Convenient 50 ml cartridges make mixing & application of Take 1 Advanced precise and easy Flowable, highly flexible and hydrophilic Volume For busy offices, Take 1 Advanced Volume delivery speeds up impression taking, reduces hand fatigue and lowers cost per use Hand Mix For instances when a higher viscosity tray material is desired and other mixing methods are unavailable Highly thixotropic with incredible tear strength The perfect balance between flow and body Outstanding dimensional stability and elasticity Ultra-high viscosity for extra mechanical compression Take 1 Advanced The Prosthodontic Procedure Guide to Cementation All you need is Kerr 5 STEP PRODUCT KERR PRODUCTS Check Clearance Clearance Measurement Flex Tab Bite Registration Impression Material Take 1 Advanced Bite Registration Temporization Material Temporary Crown & Bridge fabrication FILL-IN Temphase Temporary Crown & Bridge cementation TempBond Temporary Cements Your practice is our inspiration.™ 6 Temporary Cement removal OptiClean Rotary Instruments Permanent Cementation of Crown & Bridge Maxcem Elite NX3 Permanent Cements Veneers Step: Isolate Preps Plastic Interproximal Strips Hawe Striproll Hawe Transparent Strips Finishing & Polishing Interproximal Finishing Strips Polishers OptiStrip Identoflex Porcelain / Ceramic Polishers Identoflex Diamond Ceramic Polishers Guide to Cementation All you need is Kerr 7 Mechanical & Physical Properties... …what are they and why are they so important in cementation? “all mechanical properties are measures of the resistance of a material to a deformation/fracture under an applied force” A dental prosthesis is designed with multiple functions in mind. It is a man made object that is replacing natural teeth lost for any number of reasons. It needs to be esthetically pleasing for the patient, provide protection of underlying teeth, fit into the existing dynamics of the mouth and occlusion, AND be strong enough to last years, resisting the forces of mastication. Given the fact that in normal biting and chewing the average biting force is 170 pounds, it’s a small miracle that from a dentist’s impression, a dental technician is able to fabricate a piece of functional art so precise! Your practice is our inspiration.™ 8 Compressive Strength The maximum stress a material can withstand when subjected to compression. * A high compressive strength means the cement can better resist the compressive stress or chewing force. Tensile Strength The maximum stress a material can withstand when subjected to tension. * A high tensile strength means the cement can better resist the tensile stress (e.g. experienced when you chew sticky food). Bond Strength Force, normalized with bonding area, required to separate two materials bonded together with an adhesive. * A high bond strength will result in a long and lasting restoration. Shear Bond Strength Shear force, normalized with bonding area, required to separate two materials bonded together with an adhesive * A high shear bond strength will result in a long and lasting restoration. Elastic Modulus A measure of rigidity of the material. * Its importance is unknown for a cement. Basically you do not want a cement that is too soft as it will not adequately support the restoration under stress. Mechanical Properties Film Thickness The thickness of a cement under certain pressure. * If the film thickness is too large, it will interfere with the seating of the restoration. Solubility The amount of material soluble in water after the cured cement is soaked in water for 7 days. * If the solubility is too high, it will weaken the cured cement and cause marginal ditching. Setting Time Setting time is the time (from the start of mixing) when the mixed material is fully hardened. * Once the cement is set, the cement will be strong enough to withstand the forces of finishing/polishing. pH is a measure of the acidity or basicity of a solution/material. * If the pH of the cured material is too low (or acidity too high), the bond may not be durable as the cement may undergo degradation. Radiopacity Measures the capacity of a material to absorb x-ray. * A high radiopacity for a cement will allow it to show when examined with x-ray so that it will not be mistaken as gap or void. Eugene Qian, Ph. D. Principle Scientist, Dental Materials Center, Kerr Corporation Physical Properties Flexural Strength The maximum stress a material can withstand when subjected to bending. * A high flexural strength means the cement can better resist the bending stress when the tooth is flexed.

It is easy to use, has sufficient strength over a relatively short period of time to withstand mastication and keep temporary crowns and bridges in place while the eugenol base soothes pulpal tissue. For patients allergic to eugenol the TempBond NE version is equally effective. If a concern arises because a restoration's bonding ability may be affected by eugenol, the TempBond Clear is a great choice. With availability in automix syringe delivery, the convenience of this product takes a seat, second to none. Dr. Isaac Novak Your practice is our inspiration.™ 10 TempBond™ Temporary Cement TempBond™temporary cement for trial restorations or temporary crowns and bridges withstands mas- tication, seals the restoration and prevents seep- age, yet is easy to remove. Non-eugenol TempBond NE™will not inhibit the polymerization of permanent resin cements and acrylic temporaries. And resin-based TempBond Clear™with Triclosan is the most translucent provi- sional cement in the market for superior esthetics. Research TempBond was developed in 1961 based on zinc oxide-eugenol chemistry, a classic setting reaction with over 100 years of clinical history. Then uploads/s3/ cement-guide.pdf
