  • 4. The Carriere Distalizer
  • 5. The Carriere DistalizerWhat is it?• It is a Class II direct bond appliance: it creates a Class I molar and canine relationship – Class I platform of occlusion• Bonded from cuspid to first molarHow does it work?• It is used to (1) bodily di t li maxillary posterior segments while i dt b dil distalize ill t i t hil correcting (2) upper first molar rotation and (3) uprighting.• Produces a distal rotational movement of the maxillary first molars around their palatal roots when necessary roots,• Simultaneously, produces a light and uniform force for distal molar movement.• Independently, moves each posterior segment, from canine to molar, as a unit.• No wire changes involved therefore it eliminates the distorting collateral forces that appears with every wire changes• Minimal root resorption
  • 6. Molar pad: Ball that Characteristics articulates in a socket Hooks on pad: for the attachment of the Cl th Class II elasticsMold InjectedMetal (MIM),made of Nickel Arm: runsFree Stainless posteriorly over Canine pads = AllowSteel the two upper the distal movement premolars in a of the canine along slight curve the alveolar ridge without tipping.
  • 7. The Carriere Distalizer – What is it?• Direct bond appliance to cuspid and first molar used to bodily distalize maxillary posterior segments while correcting upper first molar rotation and uprighting. i hi• Requires a lower source of anchorage such as a lingual arch or essix and activated with ¼ i h h ti t d ith inch heavy elastic. l ti• Goal is to treat and correct the Class II at the beginning of treatment BEFORE brackets are placed in mo th lea ing mouth leaving doctor with Class I platform.
  • 8. The Carriere Distalizer – What is it?• Average treatment time is only 3-4 months due to reduction in competing forces caused by braces and anterior teeth p g y (battle of the curve).• Non-invasive, Nickel Free design for better bio-compatibility and patient comfort.• Low inventory solution with no lab fees. Bonds with bracket adhesive.• Fastest growing and most p p g g popular ClassOne p product.• 3 JCO articles released.
  • 9. How it Works• The Carriere Distalizer mimics a human ball/socket jointallowing the first molar to rotate and upright.• Built in stops engineered in the appliance keep the molarfrom over-rotating or distal tipping. g pp g
  • 10. How it Works• The stiff arm maintains exact space bet een e act between pre-molars during distalization.• The cuspid pad is fixed and will not allow the cuspid to tip.

  • 72. Appliance Placement
  • 73. Instruction for use (cast)Measurements: Using a distometer measure from the midpoint on the facial surface of the maxillary first molar (buccal groove) to the midpoint of the facial surface of the maxillary canine. Measurements can be made intraorally or on a recent cast. (Distometers included in Distalizer case).Selections: Find the correct length Distalizer — using distometer. Using finger pressure, adjust the Distalizer bar to maximize conformity of the cuspid pad t the surface of the cuspid. M d to th f f th id Many O th d ti t Orthodontists find it easier to fit the Distalizer to a recent cast.
  • 74. Measurement Intra Oral Intra-Oral
  • 75. Bond Preparation• Mark Embrasure: Place marks at embrasures mesial to the molar and distal to the cuspid. These marks assist in bonding of Distalizer. •Wax Molar ‘Joint’: Place wax at the ‘ball and socket’ joint to j enhance stability of intraoral bonding (be careful not to get any wax on bonding pad) pad).
  • 76. Prep Bonding• Coat: Cover the entire Distalizer pads with light cure composite.• Cover: Protect the Distalizer pad from ambient light prior to intraoral placement. Cotton rolls shown in photo below prevent light screen from making contact with Distalizer pads coated with light cure composite.
  • 77. Prep PatientIsolate: Using lip retractor,dry triangle, single cotton roll, and/or lowvolume suction ensure adequate intraoral suction,access while minimizing moistureEtch: Enamel acid etch the surface of the firstmolar and cuspid as appropriate for the materialselected.

  • 98. Distalizer FAQ• What if the cuspid is not erupted or too high to bond? – If the distalizer cannot be bonded to cuspid, doctor can either move the appliance to the 4 and 7 or use one of our new smaller sizes to span from the 4-6.• What about patient compliance? – We have had very few docs report non-compliance. The main reason is the Distalizer is used at beginning of treatment when compliance is best; not mid-way through when the patient has already been put through pain. Also, Distalizer is very simple and comfortable in mouth. Patient also likes that they do not have to have brackets in mouth for initial phase of treatment. If doctor properly explains benefits, patient and parent will want to cooperate with treatment treatment.• How do you bond? (Bonding Demo Video) – Using your regular bracket adhesive, we recommend bonding the 1st molar first. The ball/socket joint will then allow you to lay the distalizer down on to the cuspid for accurate placement. A bonding prep guide is available for more detail.• What happens to the second molar? Third molar? – The second molar will distalize with the rest of the posterior segment. There is no need to extract.
  • 99. Distalizer FAQ• Will I have lower anterior flaring? – Possibly depending on the source of anchorage chosen. With a lower lingual arch, there can be some slight flaring of the lower anteriors In some arch anteriors. cases, this may be wanted. If not, using an Essix or mini-screw will prohibit lower flaring.• Can I use in a Uni-lateral Class II case? – Yes The distalizers come in a left and right and can be used together (bi- Yes. lateral) or separate (uni-lateral).• Can I use in Mixed Dentition? – Mixed dentition Class II with fully erupted first molars, for first phase treatment.• Can I use the Distalizer to treat a Class III by placing on lower? – No
  • 100. Distalizer FAQ• How do I know what size Distalizer to use? (Distometer Picture)• Will I have extrusion of the canines?• What is the difference between this and using Class II elastics? – Treatment time and correction of the first molar are the biggest differences. When using Class II elastics with braces, movement is slower because of the competing forces in the mouth. Since the distalizer is done pre-braces, those f th forces are eliminated and th di t li ti process h li i t d d the distalization happens much h faster. Plus, the distalizer corrects the molar rotation for you at the same time. By treating the Class II first with the distalizer and then treating the Class I later, the doctor simplifies the case reducing time and increasing patient comfort.• How far can I distalize the molars with this appliance? – Based on 60 case studies, average distalization was 4 mm. Maximum was 6 mm and min was 3 mm.• What happens with the p pp pre-molars since they are not bonded? y• Do I get tipping of the cuspid? – No. It might seems sometime, but it does not• Can this be used with Invisalign? (Invisalign Demo Video)
