[0016] A preferred embodiment of the expander is its dimensional features, fitting within a maximum parallelepiped volume of 16mm x 10mm x 9mm.
Background
[0017] Maxillary expanders are mechanical devices used to enforce the maxilla disjunction, e.g., the lateral distension of the palatine suture. The palatine suture is the connection of the palate bones (e.g., palate), which can be expanded by applying the correct force. This is an indispensable medical procedure in the majority of orthodontic correction treatments (e.g., narrow maxillary bones). Starting with "acquiring space" inside the oral cavity, the treatment is followed by repositioning and alignment of
teeth and frequently adjustment of the supporting bones. The maxillary expansion also distends, sideways, the outer nasal walls reducing the air intake constriction and easing up breathing.
[0018] The posterior maxillary constriction with concomitant crossbite is one of dental-skeletal problems more commonly found in clinical practice. This type of maxillary hypoplasia is often seen as a congenital or acquired deformity also including cleft lip palate patients. In skeletally mature patients, this condition can be corrected by surgically assisted rapid maxillary expansion. Angell introduced the treatment process in 1860 proposing the lateral disjunction of the upper jaw using mechanical means.
[0019] The effects of this disjunction, generally designated maxillary expansion, are not, however, confined to the upper jaw, as it largely interacts with many other bones. The expansion process of the maxilla laterally separates the outer walls of the nasal cavity (causes the reduction of the palatal vault and straightening of the nasal septum). This remodelling reduces nasal resistance, increases inter-nasal capacity therefore improving respiration.
[0020] Conventional expansion of the middle palate suture is indicated for children and young people who need to correct a pathological cross discrepancy. This procedure is preferably used in situations of bilateral cross bite, but also in patients with cleft lip and palate with maxillary growth inhibition. The ultimate objective of the treatment is the disjunction of the mid palate suture, causing a transverse expansion in both parallel segments, which in turn broadens the base of the upper jaw and extends also to the nasal cavity eventually improving ventilation.
[0021] A typical orthodontic device (breaker / expander), dedicated to the maxillary expansion, comprises two essential components: the actuator mechanism that provides the movement and the anchors, which transfer the strain and movement. The
activation mechanism is placed close to the suture in order to minimize the space occupied inside the mouth. The anchoring device is often composed of rods and metal bands that are generally placed on permanent molars and also on the first premolars.
[0022] There are 4 types of devices for mid-palatal disjunction that can be classified according to their activation form: screw, spring, magnetic and shape memory alloys.
[0023] The most common expander device in the market is the Hirax and its technology is based on a metallic screw. It is small, robust and sterilizable. Devices such Hirax are generally activated twice per day, using a cranking metal key, pin type, inserted inside the mouth within a hole in the screw. The key has to be cranked in the direction of the throat. Adding to this complex operation which also requires safety precautions while using the cranking key, is the fact that rapid expansion generates stress peaks of relatively high intensity causing discomfort, even pain and occasionally diplopia (double vision). Considering the referred drawbacks of this procedure, it is not uncommon an inconsistent treatment plan due to condescending approach to the patients suffering. Technically there is no control what so ever to the amount of stress and speed of the activation and treatment plan.
[0024] Rapid expansion is not consensual among medical society given the stresses imposed to the muscles and bone structure.
[0025] Spring and memory shape alloy appliances base their technology on the recovery of the elastic energy previously stored. Once activated these devices produce continuous, fickle and poorly predictable force as it depends of the displacement (spring) and of the material properties (spring and memory shape alloy).
[0026] The mechanisms based on magnets also produce continuous forces, which however decrease with the inverse square of the distance, thus increasing uncontrollably as the distance between magnets is reduced.
GENERAL DESCRIPTION
[0027] The described invention fits within the technical field of orthodontic devices, materializing in an electromechanical device performing the process of palatal disjunction, also called maxillary expansion.
[0028] The present invention relates to an electromechanical device for orthodontic correction designed to be incorporated within an expander and promote a controlled, continuous and autonomous disjunction of the maxilla necessary for a correction process of orthodontic pathological transverse discrepancy.
[0029] The disclosed invention is an electromechanical mechatronic device of an expansion device with enhanced efficiency, independent activation and endowed with enhanced, usability and user comfort. It is composed by an integration of five main parts: encapsulation (a, b), actuator (la, lb), power source (2), control electronics (3) and optional communication electronics,
[0030] The described invention focuses only on the activation mechanism and not in the various anchor methods or protocols for clinical usage of devices of this nature.
[0031] From the efficiency standpoint, it is a device capable of providing constant force throughout the treatment allowing greater exposure of the mid-palatal suture to physiological stresses. On the other hand the final result is a rapid tailor made expansion avoiding, simultaneously, users' intervention (no need for manual activations).
[0032] Notice that the expansion described is designed to perform upon the mid- palatal suture causing its expansion and is not meant to enact on the patients teeth. It is generally known that maxillary and teeth corrections are substantially dissimilar processes.
[0033] In fact, orthodontic corrections regarding the movement of teeth must use forces of low intensity in order to activate the osteoclasts that remove the cement that connects teeth onto the bone. This slow ungluing procedure permits the movement of teeth repositioning it to the desired position and orientation. Moreover, if forces of higher intensity were used a contrary effect would be stimulated, i.e., instead of activating osteoclasts that remove the cement, the osteoblastic activity would be triggered causing the strengthening of teeth-bone bonding. Thus, the maxillary expansion has to use forces which magnitudes are much higher than the ones used for teeth correction.
[0034] On the other hand, limiting the maximum force, preferred but optional, further allows the procedure to be painless as there are no stress peaks during the activation period.
[0035] Alternative performance protocols are possible, namely progressive force curves, constant or progressive disjunction speeds, combined (or not) with maximum force protocol. It will be even possible to set thresholds for force or different programs according to time of day, or according to the activity of the patient denoted by its movement easily detected by an accelerometer, for example.
[0036] The shape of encapsulation is economically designed to fit the expander next to the mid-palatal suture, minimizing occupation of volume within the mouth.
[0037] The encapsulation is composed by two concurring sliding parts (a, b), preferably tight with no slack. Air-tightness is ensured by a sealant type micro O-ring (4) placed around the inner sliding component. The expansion is a result of the relative displacement of the two sliding parts, preferably one inner part (a) and one outer part (b), going in opposite directions while enacted by the actuator.
[0038] The displacement is enforced by an actuator (la, lb), preferably piezoelectric of small dimensions (approx. 3mmx3mmxl2mm) or small size DC brushless electric engines, fed by an electric power source (2). The power output by this actuator is, with current techniques, able to be lower than 75mW.
[0039] Other types of mini or micro electric engines may be used. Preferably, the actuator shall be connected to a spindle screw.
[0040] Preferably, two spindle screws will be used with two actuators, each connected to its individual actuator.
[0041] The required power source for the actuation, for the control and for the communication is ensured by a battery (2), preferably 3.0 V, of reduced size and of such capacity that ensures operation in continuous maximum force mode, during a period above 15 days.
[0042] For motion control operations is used an electronic circuit (3) preferably integrated, with a built-in controller and an electronic communication device (transceiver), embedded along a set of electronic components (resistors, transistors, reels, oscillators and balloons).
[0043] Alternative configurations are also possible, namely integration of the components on a PCB (3) preferably along with the electric motors or actuator motors (la, lb). One preferential solution is system-on-chip, SoC (31), with the ability to communicate using radio frequency, electronic control drives (32) for each motor of the actuator (la, lb), encoder/es (33), antenna (34), hidden electronic components, along with one or more power batteries (2).
[0044] The extent of the force exerted can be ascertained either through specific sensor or sensors, or through which consumption of the actuator (or their motors).
