Orthopedic Appliances Al Esraa University College Dentistry Department / Orthodontics د0 هبة محمذ الخطيب 4th Grade Lec: 16 Orthopedic Appliances Orthopedic appliances generally use teeth as “handles” to transmit forces to the underlying skeletal structures. Basis of orthopedic appliance therapy resides in the use of intermittent forces of very high magnitude. Such heavy forces when directed to the basal bone via teeth tend to alter the magnitude & direction of the jaws by modifying the pattern of bone apposition at periosteal sutures & growth sites. There are 2 types of forces used in orthodontics 1) orthodontic force – when applied brings about dental change. They are light forces ( 50- 100 gm) bringing about tooth movement. 2) orthopedic force – when applied brings about the skeletal changes. They are heavy forces ( 300-500gm) that bring about changes in the magnitude & direction of bone growth. The appliances that produce skeletal changes by applying orthopedic forces are known as orthopedic appliances. Since they employ heavy forces, adequate anchorage required is gained by extra oral means using occipital, parietal, frontal cranial bones and cervical vertebrae. PRINCIPLES OF USING ORTHOPEDIC APPLIANCES The following are the basic principles of using orthopedic appliances effectively 1) Magnitude of force Extra oral forces of much greater magnitude, in excess of 400gms per side is required to bring about skeletal changes. Most orthopedic appliances employ forces in the range of 400-600 gm per side to maximize skeletal changes and to minimize dental change. Such heavy force compress the periodontal ligament on the pressure side & cause hyalinization, which prevents tooth movement. 2) Duration of force Orthopedic changes are best produced by employing intermittent heavy forces. Intermittent forces of 12-14 hours duration per day appear to be effective in producing orthopedic changes. An intermittent heavy force is less damaging to the teeth and periodontium than a continuous heavy force. 3) Direction of force Orthopedic force should be applied in the appropriate direction to have a maximum skeletal effect. The desired changes are best achieved when the line of force passes through the center of resistance of the skeletal structures to be moved. The force direction or force vector should be decided depending on the clinical needs. 4) Age of the patient It is advisable to begin orthopedic appliance therapy while patient is still in the mixed dentition period, to make most of the active growth occurring prepubertal growth spurt. Treatment may have to be continued until the completion of adolescent growth, so as to prevent relapse caused by the re-expression of patients fundamental growth pattern after cessation of orthopedic therapy . 5) Timing of force application Optimum timing of extra oral force application is considered to be during evening & night. This is because, an increase release of growth hormone and other growth promoting endocrine factors has been observed to occur during the evening & night rather than during the day. Evidence suggest that skeletal growth is associated with sleep onset & follows circadian pattern. Myofunctional appliances A removable or fixed appliance which favorably changes the soft tissue environment” (Frankel,1974) A removable or fixed appliance which changes the position of mandible so as to transmit forces generated by the stretching of the muscles, fascia &/or periosteum, through the acrylic and wirework to the dentition and the underlying skeletal structures. (Mills,1991) Classification of Myofuctional Appliances By Profitt ; (i) Teeth borne passive-myotonic appliances e.g.: Activator, Bionator (ii) Teeth borne active-myodynamic appliances e.g.; Bimler’s appliance, elastic open activator. (iii) Tissue borne passive appliances e.g.: Oral screen, lip bumpers (iv) Tissue borne active appliances e.g.: Frankel’s appliances (v) Functional orthopedic magnetic appliances (FOMA) Indications of myofunctional appliances 1- The patient must still be growing, (phase of rapid growth). 2- The pattern and direction of facial growth should be reasonably favorable. 3. The patient must be well motivated because they are relatively bulky and must be worn most of the time. Advantages of functional appliances: 1- Can be used in early mixed dentition. 2- Less chair side time, number of visits and minimal chair side adjustment. 3- Reduce the severity of the case. 4- Favorable growth of the jaw with favorable dentoalveolar compensation. 5- Easy to maintain oral hygiene, less side effects of mechanotherapy such as, root resorption and decalcification. 6- Acceptable, can be worn during night. 7- The cost is relatively lower than fixed appliance. Disadvantages of functional appliances: 1. Success of functional appliances depend on patient cooperation. 2. Not possible to correct rotation, crowding and there is no precise tooth movement. 3. Treatment duration is often prolonged. 4. Treatment must be carried out at a precise and relatively critical time. 5. Not useful in adults where active growth is completed. Limitations of Functional appliances: 1. They can be used to correct basal bone/arch relationship and cannot be used for correcting dental malocclusion. 2. It is not useful in managing adult patents where the active growth is completed. 3. It requires a final phase of fixed appliance therapy to achieve final detailing or final alignment of tooth position. 4. The result of treatment is totally dependents upon the patient's cooperation. 5. They have a tendency to increase the lower facial height and hence, they cannot be used in patients with backward rotating mandible. Mode of action Dento-alveolar changes: They produce dentoveolar changes by teeth movement. In fact, their major effect is on the position of teeth and alveolar process. Changes in maxillary growth: There is a restriction of forward growth of the maxilla similar to the effect of headgear. Changes in mandibular growth: There is evidence that functional appliances may induce on average an extra of 1-2 mm of the growth of the mandible. Changes in the glenoid fossae: Remolding of the glenoid fossae. They can bring about the following changes: 1. An increase or decrease in jaw size. 2. A change in spatial relationship of the jaws. 3. Change in direction of growth of the jaws. 4. Acceleration of desirable growth. Duration and timing of wear Functional appliance treatment should be started before the pubertal growth spurt when the mandible may exhibit increased growth rate. Functional appliances should be worn for at least 10- 12 hours a day. These appliances should be worn at nighttime as this is when growth takes place. Oral screen Oral screen is a thin sheet of acrylic processed over the occluded waxed working casts extending deep into the sulcus both labially and buccally which act as a screen between teeth and musculature. Vestibular screen does not contact teeth as compared to oral screen. Indications: 1. To intercept mouth breathing, thumb sucking, tongue thrusting, lip biting & cheek biting. 2. To perform muscle exercises to help in correction of hypotonic lip & cheek muscles. 3. Mild anterior proclination. LIP BUMPER “Combined removal-fixed appliance”. Used in both maxilla & mandible to shield the lips away from the teeth. Uses: -In lip sucking patients. -Hyperactive mentalis activity. -To augment anchorage -Distalization of first molars. ACTIVATOR This is a one-piece functional appliance, with minimal acrylic to improve patient comfort. As there is no molar capping on the lower posterior teeth, these teeth are free to erupt. The Activator is therefore useful when trying to reduce a deep overbite. Indications: -In actively growing individuals with favorable growth patterns. -class II div I malocclusion -class II div II malocclusion -class III -class I open bite -class I deep bite -as a preliminary treatment before major fixed appliance therapy to improve skeletal jaw relations. -children with lack of vertical development in lower facial height. Contraindications: -correction of class I cases with crowded teeth caused by disharmony of tooth size & jaw size. -in children with excess lower facial height. -in children whose lower incisors are severely proclined. -in children with nasal stenosis caused by structural problems in the nose or chronic untreated allergy. -in non-growing individuals. Advantages: -uses existing growth of the jaws. -minimal oral hygiene problems. -intervals between appointments is long. -appointments are short and minimal adjustments required . - relatively economic. Disadvantages: -requires very good patient cooperation. -cannot produce a precise detailing & finishing of occlusion. The Twin-Block Appliance It is well tolerated by patients as it is constructed in two parts. The upper and lower parts fit together using posterior bite blocks with interlocking bite-planes. The patient is encouraged to posture the mandible forwards, so that the lower block occludes in front of the upper block. The appliance can be worn full time, which means that rapid correction is possible. It is also possible to modify the appliance to allow expansion of the upper arch during the functional appliance phase. It is also easy to reactivate the twin-block appliance. This means that during treatment if further advancement of the mandible is required, it is possible to modify the existing appliance rather than having to construct a new appliance. One of the side-effects of the twin-block appliance is that; The posterior teeth are prevented from erupting by the occlusal coverage of the bite blocks. Some clinicians will trim the acrylic away from the occlusal surfaces of the upper block to allow the lower molars to erupt. Any remaining lateral open bites are closed down in the fixed appliance phase of treatment. HERBST APPLIANCE The Herbst appliance is a fixed functional appliance. It is as successful at reducing overjets as the twin-block appliance. It is however slightly better tolerated than the bulkier twin-block appliance, with patients finding it easier to eat and talk with it in place. The principle disadvantages are the increased breakages and higher cost of the Herbst appliance. Indications: -correction of class II malocclusion due to retrognathic mandible.

GOTTLIEB, DDS DR. JAMES MCNAMARA DR. GOTTLIEB Jim, give us a little background on how you became involved with the Frankel Appliance. DR. MCNAMARA After graduation from the University of California orthodontic program in 1968, I came to Michigan for a Ph.D. in anatomy. I sent a copy of my Ph.D. thesis on functional protrusion experiments in monkeys to a number of people whom I knew were interested in formand function. Tom Graber suggested that Professor Rolf Frankel might be interested in myexperimental work. Several months later, Professor Frankel wrote to me stating that he felt that I had shown experimentally what he had been doing clinically for about 15 years. Frankel was interested in the fact that the musculature was being monitored in my experiments, as well as the skeletal and dental aspects. In 1973, I went to the Third International Orthodontic Congress in England, and Frankel was on the program. He cited me twice in his presentation, and we began a professional and personal friendship which has endured to this day. I had a chance to thoroughly discuss Frankel therapy during his visit to the United States in 1974, and shortly thereafter I started using his approach in treating a few patients.

MATERIALS AND METHODS: Sixty-four adult Caucasians patients were selected to be part of this retrospective study. Pre and post-treatment digital models created from an iTero® scan were obtained from a single orthodontist practitioner. Digital models from Clincheck® were also obtained from Align Technology® to measure the prediction models. Linear values of upper and lower arch widths were measured for canines, premolars and first molars. A paired t test was used to compare transverse changes planned on Clincheck® with the post-treatment measurements. Variance ratio tests were used to determine if larger changes planned were correlated with larger errors RESULTS: For every maxillary measurement, there was a statistically significant difference between Clincheck® and final outcome. (P < .05) For every lower arch measurement at the gingival margin, there was a statistically significant difference between the Clincheck® planned expansion and the final outcome.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The purpose of this case report is to add another means of treatment for the anterior crossbite malocclusion in early mixed dentition. The selected functional device is an eruption guidance appliance (EGA). The analysed patient had a functional anterior crossbite, a mandibular protrusion tendency, and a normodivergent growth pattern. The early treatment was suggested to correct the malocclusion and avoid unfavourable occlusal conditions that could end in a class III malocclusion growth pattern. After 18 months of treatment, with night-time use, the malocclusion was completely resolved. This therapy strategy allowed the correction of the sagittal jaws’ relationship and maximum control of the vertical dimension. After 2 years of follow- up, the results were preserved. The peculiarity of this kind of intraoral orthodontic tools is the use of the erupting forces rather than the active forces.

D. Dental College and Hospital, Mathura, India1,2,3 [email protected] Abstract: Malocclusion Functional appliances or myofunctional appliances are referred to appliances that depend upon the oro facial musculature for their action. These appliances transmit, eliminate or guide the natural forces of the musculature and are used to alter the mandibular position in the Sagittal, Vertical and Transverse plane resulting in Orthopedic and Orthodontic change. They are designed to alter the activity of various muscle groups that influence the function and position of the mandible in order to transmit forces to the dentition and the basal bone. Functional appliances are given in the management of skeletal class II malocclusion and Class III malocclusion in growing children. They are also called “GROWTH MODIFYING APPLIANCES” and “INTERCEPTIVE APPLIANCES. They are used for growth modification procedures that are aimed at intercepting and treat in jaw discrepancies by increase or decrease in jaw size, change in spatial relationship of the jaws, change in direction of growth of the jaws and acceleration of desirable growth. A new pattern of function dictated by the appliance leads to development of corresponding new morphologic pattern. The new morphologic pattern includes a different arrangement of the teeth within the jaws, an improvement of the occlusion and an altered relation of jaws.

  • Interception of Skeletal Class 3 Malocclusion with Frankle 3 Appliance in Late Mixed Dentition a Case Report
    Interception of Skeletal Class 3 Malocclusion …… U. B. Rajasekaran, et al. Interception of Skeletal Class 3 Malocclusion with Frankle 3 Appliance in Late Mixed Dentition A Case Report U. B. Rajasekaran,* Khalled Abdulla,** Abstract: Class III malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. The aim of this article was to describe and discuss a clinical case with skeletal Class III malocclusion treated with frankle 3 appliance and fixed mechanotherapy and followed up for two years. Introduction: Skeletal class III malocclusion is a growth Following the confirmation of a Class III related problem either could be due to malocclusion through the cephalometric retrognathic maxilla or prognathic mandible or analysis, clinical differential diagnosis was a combination of both.1 The optimal treatment accomplished by verifying the occlusion time for skeletal class III due to retrognathic pattern at either the intercuspal position (IP) or maxilla and normal mandible is early mixed at the centric relation (CR). The patient dentition as anterior crossbite due to showed no functional shifting of the mandible. retrognathic maxilla will further restrict the This clinical and cephalometric findings maxillary growth.2,3 There are various confirmed a skeletal Class III malocclusion appliances in peadodontic and orthodontic due to the maxillary retrognathism. literature described for treating skeletal class III malocclusion.3-6 In our case we opted for The patient was at a late mixed dentition stage, frankle 3 in place of all other appliances with almost 40 percent of growth left as because patient demanded a removable confirmed from hand and wrist radiographs, so intraoral appliance.
