(MRC), is a highly developed MyofunctionalOrthodontic System which combines habit correction, arch expansion and dental alignment into oneintegrated system. It satisfies the demand from parents for a less invasive way to straighten teeth withoutbraces, while also allowing children to develop to their genetic potential.www.myoresearch.comIt is not always possible to achieve all treatment goals. Treatment success is heavily dependent on the patient’scompliance to Myobrace treatment, their biological ability to change habits as well as growth patterns.Starting treatment early increases the chance of an optimum result.

Myofunctional OrthodonticsFor more than 27 years, Myofunctional Research Co.(MRC) has recognised breathing disorders as the majorcause of malocclusion, poor jaw growth and TMJ disorder.By effectively changing the way orthodontics for childrenis performed, the Myobrace myofunctional orthodonticsystem, by MRC, fundamentally delivers airway and habitcorrection to resolve orthodontic problems.“The paucity of our present knowledge of etiology in orthodontics compels us to attack the cause andeffect relationship from the wrong end - that of effect. By working backward we shall undoubtedly arriveat the beginning, someday. How nice it would be to approach it from the other end.”Graber, T. M. (1962) Orthodontics; Principles & Practice, Chapter 6, Etiology of Malocclusion - Extrinsic or General factors.75% of growing children have malocclusion and incorrect facialdevelopment. Soft Tissue Dysfunction is the major cause.What causes orthodontic problemsThe majority of children now have crooked teeth,which is evident from three to five years of age and isoften attributed to hereditary factors. However, ratherthan blame genetics for crooked teeth and poor jawdevelopment, modern research has produced evidencethat points to other causes.Mouth breathing, incorrect tongue positioning,reverse swallowing and thumb sucking – known asincorrect myofunctional habits – are the real causes ofmalocclusion and poor cranio-facial growth.If a child breathes through their mouth during theday or while sleeping at night, the tongue drops to thebottom of the mouth, which results in upper and lowerjaw development problems.This restricted development limits the space availablefor erupting teeth and prevents them from emerginginto their ideal natural position.“You start treatment when you discover the poor oralhabits that are going to create problems and youaddress the habits, not the teeth.” Dr Barry Raphael –Orthodontist (Clifton, New Jersey, USA)Incorrect tongue positioningrestricts development of themaxilla causing crowding.Reverse swallowing restrictsmandibular development,causing crowding and class II.Limitations of orthodontic treatment with bracesThe orthodontic profession now recognises that although braces can effectively align the teeth, maintainingthis alignment requires permanent retainers for life. In addition, research has found that damage to the roots(root resorption) occurs in virtually every case (Darendeliler, May 2011). Parents are increasingly questioning theeffectiveness and safety of orthodontic treatment with braces.RELAPSE - up to 90%. Relapse occurs in up to 90% ofENAMEL DAMAGEcases when retainers are removed.

The Myobrace SystemMyofunctional Research Co. (MRC) fills the needfor less mechanical and more biologically based,myofunctional pre-orthodontic treatment by offering awide range of modalities that address the underlyingcauses of malocclusion and airway dysfunction.The Myobrace myofunctional orthodontic systempackages airway and habit correction, arch expansion,and dental alignment into a comprehensive treatmentsystem ideally suited to treat children aged 3-15years. By focusing on the aetiological factors thatcause malocclusion, the appliances aim to correctthe poor myofunctional habits affecting the teeth,jaws and facial development, offering patients a morenatural orthodontic solution.Mouth breathing restricts correct forward growth anddevelopment, which reduces space for the anteriorteeth and third molar eruption.How Myobrace Appliances WorkSince 1989 MRC has pioneered the use of singlesized, pre-fabricated appliances using myofunctionalhabit correction while the child is still growing toimprove jaw development. This allows the teeth toalign correctly without the need for braces and hasadded health benefits as well.The fundamental keys to this treatment are obtainingcorrect nasal breathing, correcting tongue restingposition, and retraining the oral muscles to functioncorrectly. Along with habit correction, Myobrace appliances apply light forces to the teeth to assist theteeth to align into their natural position, usually withno need for braces or extractions. The appliances areworn for just 1-2 hours each day, plus overnight whilesleeping. A successful treatment outcome requiresgood patient compliance.There are 3-4 stages of appliances that are designedfor each dentition, which are specific to that agegroup. Myobrace appliances effectively train thetongue to position correctly in the maxilla, retrainoral musculature and exert light forces to expand thejaws and align the teeth.The effect of the correcttongue position andpatented DynamiCore develops the arch form,allowing better archlength and improvingdental alignment.Treatment Goals: Correct nasal breathing. Correct function of oro-facial musculature. Correct arch form and tooth alignment.The SpotBreatheCorrect BreathingCorrect Rest PositionRollCorrect SwallowingLips Together At Rest“What Myobrace does is treat the underlying causes ofmalocclusion - teaching children to breathe throughtheir nose, put the tongue on the roof of the mouth andkeeping the lips together, so the jaws can grow to theirgenetic potential, then there is plenty of room for theteeth to come in straight with the jaw relationship inClass I.” Dr Chris Farrell (Myofunctional Research Co. CEOand Founder)Above: Case study using the Myobrace for Teens appliance series with the BWS and lip trainer - see appliance selector onmyoresearch.com.

MYOBRACE T3The T3 is the tooth alignment stage of treatment.The DynamiCore acts as an arch wire and thetooth slots increase arch length, along withassisting dental alignment. Compliance with theT3 is essential to prevent losing arch form space,which occurs when the appliance is not wornregularly. The T3 predominately focuses on dentalalignment, but still has habit correction featuressimilar to the T1 and T2.

For the adultpatient, all the growth has taken place and theteeth are in their most stable position. Mouthbreathing and incorrect swallowing habits have beenestablished over many years and are more difficultto correct. For these reasons, results in adults arenot as predictable as with children.

MIXED DENTITION CIIIMyobrace for Interceptive Class III The majority of class III malocclusions are a resultof a deficient maxilla due to mouth breathing and alowered tongue posture. This results in both skeletaland dental class III malocclusions. The Myobrace Interceptive Class III appliance system is specificallydesigned to correct Class III malocclusions. Mosteffective in the early mixed dentition (ages 5-8).

Speciality AppliancesFOR ALLAGESThe Lip Trainer is designed to establishan adequate lip seal and strengthen lipmuscles. Some patients may show signs of lipincompetency or poor muscle tone around thelips (Orbicularis oris muscle). The Lip Trainer improves lip seal, strengthens and stretchesthe lip muscles to reduce over activity whenswallowing. It can be issued at any stagethroughout treatment as an adjunct to theother Myobrace appliances.IMPROVE LIPCOMPETENCYThe Lip Seal Trainer is designed to establish an adequate lipseal, which is essential to establish nasal breathing. Used inconjunction with the Lip Trainer .Arch Development - AGES 8 to 15 (MIXED AND PERMANENT DENTITION)BWS : The Farrell Bent Wire System (BWS ) is a light-wire appliance that produces arch development when used incombination with MRC’s appliances (the Trainer or Myobrace systems). It is particularly effective in gaining anteriorarch expansion. In the late mixed dentition, most of the jaw growth is completed. Extra expansion is needed to establishmore space for the teeth and correct positioning of the tongue. The Myobrace T2 can achieve this however, the BWS combined with the T1 BWS can obtain this result quicker and more effectively.FORANTERIOR ARCHDEVELOPMENTSIMULTANEOUSLYWITH MYOBRACE UPPER ANDLOWERUPPER BWS APPLIANCEBIOBLOCORTHOTROPICSBWS ON TYPODONTT1 BWS & BWS ON TYPODONTThe Biobloc System: A narrow arch form in the mixed dentition requires arch expansion, which creates more room forthe tongue and allows all of MRC’s appliances to work more efficiently.
