A Crowns and Bridges made of Titanium 1. Working with rematitan® Plus Investment Material Preparation Waxing of crowns and bridges can be done with the usual materials. Crowns and bridges are waxed up in the usual way. Minimum wall thickness 0,4 mm. Fitting: Crown and Bridge Technique B Hints for wax up: If thermoformed plastic copings are used, it is advisable to remove the shortened spacer foil from the plastic coping just before investing.
Muffle System To avoid gas entrapment during casting, the sprue cone must be of a certain shape. Use only the muffle bases belonging to the system with sprue formers. Muffle base with sprue former: Size 3 1 piece Ord.-No. 106-850-01 Size 6 1 piece Ord.-No. 106-851-01 Size 9 1 piece Ord.-No. 106-852-01 The base plate must be completely clean. Distance between wax frame and investment surface: max. 6 mm.
Mixing ratio: 250 g powder : 40 ml mixing liquid. Mixing time in the vacuum mixer: 60 seconds. Fill the muffle to the top with investment. Remove from the vibrator immediately. Setting time: 40 minutes. Pull off from the base/sprue former by twisting and grind the side opposite the sprue, with the dry trimmer. This promotes gas permeability of the investement in the flow-direction of the titanium. Place the muffle with the opening downwards in the cold oven.
Expansion control for Crowns/Bridges The adjustment of the expansion for the rematitan® plus investment is exclusively done by dilution of the mixing liquid. (see chart below). Attention! The mixing liquid is a concentrate which normally must be diluted: Recommendation for dilution: Crowns and bridges: 60% = 6 parts of liquid + 4 parts of distilled water. Conical and telescopic crowns: 70–100% = dilution related to the desired friction and ways of processing.
1.2 Working with rematitan® Ultra Investment Material Important! The expansion of this investment material cannot be controlled by the mixing liquid. Never dilute the liquid with water. The expansion of the material is controlled by the temperature setting of the oven. Safety note Danger Mixing liquid: If the liquid should contact the eyes, rinse thoroughly with water and if necessary seek medical attention.

Mixing Important! Use only clean, dry mixing bowls and measuring beakers! Always keep mixing bowls and measuring beakers away from other investment materials! After mixing powder and liquid, mix the compound well by hand. Mixing time in vacuum mixer: Minimum 60 secs. Recommended 120 secs. Processing Time Approx. 6 minutes. Setting Time / Trimming 11/ 2 - 2 hours, depending on room temperature. Grinding Grinding/sanding the ring surface improves its thermal stability.
Preheating Cycle The expansion of rematitan® Ultra investment material con only be controlled by the temperature. As it is not possible to calibrate all ovens accurately, the temperature recommended by us may be increased or decreased as required. In our experience the temperature range is between 880°C und 910°C/1,616°F and 1,670°F.
1.3 Working with Trinell Investment Material Trinell is the result of ongoing development of our already proven rematitan® Ultra Investment Material for the rematitan® Casting Technique. Trinell, besides the standard work, will expedite the working cycle significantly. With the appropriate casting unit, the casting surfaces are almost oxide-free. Storage: Please store powder and mixing liquid at room temperature in a dark area.
Mixing: Always use clean and dry mixing and measuring utensils! Attention: Use one particular measuring container only for Trinell liquids. Mix well manually! Mixing time in a vacuum mixing unit: 60 seconds Attention: Do not dilute the slightly thick material. Due to the moisture content, and the timely processing time, a bubble-free investment is guaranteed.
Preheating Cycle – Alternatives Attention: The end temperature of (870–900°C / 1598–1652°F) is very important for a proper fit. Depending on oven size and calibration, the temperature may have to be adjusted, up or down. Higher end temperature = wider fit Lower end temperature = tighter fit Attention: Every package of investment contains a separate instruction sheet that gives recommendations for end temperature and holding time, according to that particular batch.
Weekend Operation: Attention: For weekend operation, use only Trinell mixing liquid! (Use Trinell Special Speed Liquid only for reduced and full speed preheating. When using overnight preheating microwave drying is imperative as it increases ring stability. After microwave drying, place casting, with the sprue facing down, into the cold oven and program the oven for preset preheating at 2 steps and cool down phase.

Model casting made of Titanium Preparation The reactive layer, also called the „alpha case“, formed at the contact zone between the rematitan® casting metal and the investment should be kept as thin as possible. Because of the special properties of titanium, such as low specific gravity, high melting point, low contraction and very high affinity for oxygen, all the factors which influence titanium must be dealt with differently than with conventional dental castings.
Setting time Setting time is 40 minutes. Refractory should not be placed in a pressure pot while setting. Drying the model 70 °C/158 °F, for 40 minutes in a circulating air drying cabinet. Note! Do not use higher temperatures, since this will affect the surface smoothness. Risk of damage to the surface (pasty). If the model is dried in the preheating oven, check the temperature and adjust if necessary. Models with too high a moisture content prevent good attachement of the wax or plastic patterns.

Use of rematitan® M-(Ti4)-casting metal rematitan® M has a higher elongation limit, tensile strength and modulus of elasticity values. rematitan® M has slightly poorer flow properties than the more commonly used titanium Ti1. However, it is easier to cast than is normally the case when using titanium grade 4. Slight modification of the casting sprues allow the fabrication of very delicate partial dentures.
Sprue /sprue former All model castings are cast from the top. Sprue formers for model casting Plastic sprue cones should be used. Note! Do not use other cone shapes than recommended. The shape of the sprue cone and the position of the sprue channel help the melt to flow cleanly. The funnel must be in the center of the casting ring, so that the muffle can be centered cleanly in the unit. Attention! The new funnels are equipped with cavity formers for better aligning of the packing rings.
Preparation for investing Contrary to the crown and bridge technique, removable restorations are made with a model which has to be invested in a ring. In order to avoid loss of pressure during the casting process, there must be a tight bond between the refractory model and the investment ring. Any deviation form the recommended materials and procedures may result in cracking of the ring due to the expansion characteristics of the investment material. This will result in miscasts.
Investing For one muffle 2 x 250 g packs of rematitan® Plus investment (Ord.-No. 107-600-00) are required. Mixing ratio = 500 g : 80 ml. Shake rematitan® mixing liquid (Ord.-No. 107-601-00) before use. For small models and a red muffle ring, and generally for blue muffle rings, 3 x 250 g packs are used. Mixing ratio: 250 g : 40 ml liquid. Note: Process rematitan® Plus investment at 18 –22 °C / 64,5 –72 °F.
Preheating the muffle Heating rate: 5 °C / 41°F per minute. 150 °C 90 min. -> 250 °C 90 min. -> 1000 °C 302 °F 90 min. -> 482 °F 90 min. -> 1832 °F 60 min. 60 min. Cooling rate: 5 °C / 41°F per minute. Slow cooling to 430 °C / 806 °F = remove muffle. Avoid temperature shock. Holding time at end temperature 430 °C / 806 °F not longer than 120 minutes.
2. Titanium one-piece casting technique One-piece casting for crowns of 2° and 4° taper is possible with the following procedure. Telescopic crowns are dealt with separately in section II. I Conical crowns 1. Preparation Wax up primary crowns on the master model. Angulation (tapering) 2° or 4°. 2. Duplication Duplicate the master model with the primary crowns using Rema®-Sil silicone (Ord.-No. 108-700-00 / 108-701-00). 3.
7. Spruing system In the upper jaw, attach 2 sprue channels of 4 mm diameter in the form of a v in the dorsal region. Length of the sprue channels are approx. 10 mm. The standard spruing system is used in the lower jaw. (see page A 11) 8. Preparation for investing The models are trimmed on the side to the waxed portions. The subsequent standing surface of the model is trimmed at an angle of 45°. Distance from the waxed model to the base surface approx. 4 mm.
II Telescopic crowns Preparation 1. The tooth arch in the silicone mould is first filled with rematitan® Plus investment, which is mixed with diluted rematitan® Plus crown/bridge mixing liquid (Ord.-No. 107-602-00). Attention! The mixing liquid is a concentrate which normally must be diluted: Recommendation for dilution: Crowns and bridges: 60% = 6 parts of liquid + 4 parts of distilled water. Conical and telescopic crowns: 70–100% = dilution related to the desired friction and ways of processing. 2.
3. Finishing of titanium castings Safety advices! Danger Abraded or separated titanium particles when hot react with oxygen and produce sparks. Caution: Risk of combustion and explosion. Cool the workpiece with water. If suction lines are used, change the filter paper regularly. Warning: Otherwise fire hazard. Warning! Always use trimming materials only for processing titanium. Keep separate! Cutting of sprues Warning! Do not overheat the casting when separating. Cool. No red heat.
Polishing Polish and shine with a soft polishing brush and special titanium polishing paste (Tiger brillant, Ord.-No. 190-350-00, see page C 6 –7). Note! To form a passivity layer, leave polished work exposed to air for at least 10 minutes. Only then steam clean or use ultrasonic cleaner. autocast universal® 230 Casting System Model casting Stand 1. 9.
Trimming of titanium castings with the rematitan® finishing kit Note on safety – Always wear safety goggles when finishing castings. – Always turn on the extractor unit during work. – The maximum rotation speeds of the various instruments must not be exceeded Description Pure titanium is a soft tough material which requires special procedures for finishing and polishing. The Finishing Set (Ord.-No.
When using rematitan® ultra investment material: Use Aluminium oxide Al 2O3 (30 µm – 250 µm) For very fine parts (inlays) careful blasting with polishing beads is sufficient. Procedure for finishing titanium Follow the finishing instructions in the correct sequence. This enables you to achieve an excellent polish on the titanium with very little effort and expense.
4. Casting with Alloys All customary dental alloys for prosthetics can be cast with the autocast universal® 230 unit. The alloys are melted on a special ceramic crucible. The electric arc is deflected over an electrode that is set in the crucible. The output of the electric arc is regulated according to the alloy being used. The tipping of the crucible is done manually via the viewing window. Preparing the casting ring Prepare casting object as usual, either with a sprue bar or directly.
Ceramic seal Only high temperature ceramic seals should be used. (Ceramic seal C – Order No. 090-012-60) Multiple uses are only suitable when the muffle base is very smooth. Do not reuse more than three (3) times. Ceramic crucible and crucible electrode Two sizes of ceramic crucibles can be used when casting with alloys. The small crucible Order No. 090-161-00 can be used for up to 36 grams of non-precious metals and for up to 45 grams of precious metal alloys. The large crucible Order No.
Melting process: Controlling the output The power output of the casting machine is controlled by an inverter from 5% to 100% by use of a potentiometer. The predetermined output setting does not only depend on the melting temperature of the alloy, but also the quantity of the casting metal. Due to excessive cooling down of the casting muffle, the melting time should not exceed 40 – 50 seconds. An automatic safety device tips the crucible after a maximum of 90 seconds.
The casting process is manually controlled via the “cast” button when the melt builds a uniform mass. To avoid partially melted ingots, place them in an overlapping pattern and have them contact one another on the crucible.
