Description
Dispositivo elettromedicale per la valutazione del bruxismo notturno Electromedical device for the evaluation of night bruxism
RELAZIONE AGGIUNTIVA ADDITIONAL REPORT
Il sensore meccanico rileva (i) la quantità di carico; (ii) la direzione del movimento della mandibola. Esso è affogato nella resina di uno splint “standard” o costruito a partire dall’impronta delle arcate dentarie del paziente. Il sensore è costituito da piccoli sensori “a foglietto”, che sono in totale 7-8. Essi servono a registrare ogni forza che supera il livello della forza della deglutizione, riportandone l’intensità (intesa in kg per dente, oppure come pressione su cm<2>), la frequenza ed anche la durata. The mechanical sensor detects (i) the amount of load; (ii) the direction of movement of the jaw. It is drowned in the resin of a "standard" splint or built from the impression of the patient's dental arches. The sensor consists of small “foil” sensors, which are 7-8 in total. They are used to record any force that exceeds the level of swallowing force, reporting the intensity (in kg per tooth, or as pressure on cm <2>), the frequency and also the duration.
I sensori sono così distribuiti sull’arcata dentaria: The sensors are distributed as follows on the dental arch:
• 1/2 per gli incisivi • 1/2 for the incisors
• 2 per i canini (1 a destra ed 1 a sinistra) • 2 for the canines (1 on the right and 1 on the left)
• 2 per i premolari (l a destra ed 1 a sinistra) • 2 for the premolars (1 on the right and 1 on the left)
• 2 per i molari (l a destra ed 1 a sinistra) • 2 for the molars (1 on the right and 1 on the left)
I sensori inquadrano gli inputs registrati all’interno di 3 ranges. The sensors frame the inputs recorded within 3 ranges.
II medico stesso, prima di “affidare” l’apparecchiatura al paziente, “setta” i limiti tra i 3 ranges di gravità in base al paziente stesso, rilevando i carichi di deglutizione e di massima contrazione volontaria su ogni sensore. The doctor himself, before "entrusting" the equipment to the patient, "sets" the limits between the 3 ranges of gravity based on the patient himself, detecting the swallowing loads and maximum voluntary contraction on each sensor.
I foglietti sensori sono inseriti nello splint direttamente a livello delle superfici di masticazione dei denti. In questo modo può essere misurata la pressione trasmessa dal dente allo splint (e quindi al dente inferiore). The sensor strips are inserted into the splint directly at the level of the chewing surfaces of the teeth. In this way, the pressure transmitted from the tooth to the splint (and thus to the lower tooth) can be measured.
La trasmissione al PC dei dati awiene con tecnologia wireless. Viene inserito nello splint un chip in grado di fare sia da trasmettitore, che di gestire una parte del sistema di rilevazione dei dati. Il chip ha dimensioni di circa 9mmx9mm, e spessore di circa Imm (+ la "base" su cui viene saldato, per uno spessore totale di 1.5mm). Il chip ha bisogno di un’ antenna esterna, che viene posizionata nel vestibolo della arcata superiore. L'antenna è anch’essa affogata nella resina dello splint. Sono inoltre affogati nella resina dello splint altri componenti aggiuntivi, compresa la batteria. The data transmission to the PC takes place with wireless technology. A chip able to act both as a transmitter and to manage a part of the data detection system is inserted in the splint. The chip has dimensions of about 9mmx9mm, and thickness of about Imm (+ the "base" on which it is soldered, for a total thickness of 1.5mm). The chip needs an external antenna, which is positioned in the vestibule of the upper arch. The antenna is also drowned in the resin of the splint. Other additional components, including the battery, are also drowned in the resin of the splint.
Il ricevitore wireless è costituito da un computer poratile a cui è collegato una penna USB con un ricevitore commerciale. The wireless receiver consists of a portable computer to which a USB stick with a commercial receiver is connected.
I/elettromiografo di superficie rileva l’intensità, la frequenza e la durata degli episodi di bruxismo (serramento e digrignamento) notturno, con particolare riguardo alle contrazioni che superano il livello della massima contrazione volontaria. L’elettromiografo ha 4 o più canali. The surface electromyograph / electromyograph detects the intensity, frequency and duration of bruxism episodes (clenching and grinding) at night, with particular regard to contractions that exceed the level of maximum voluntary contraction. The electromyograph has 4 or more channels.
Anche per quanto riguarda fattività elettromiografica di superficie, la macchina individua 3 o più range di gravità, con riguardo all’intensità, alla frequenza ed alla durata delle contrazioni. I limiti tra i vari intervalli di gravità vengono “settati” prima di iniziare l’esame in base ai valori elettromiografici di superficie dei muscoli del paziente. Also with regard to surface electromyographic effectiveness, the machine identifies 3 or more ranges of severity, with regard to the intensity, frequency and duration of contractions. The limits between the various severity intervals are "set" before starting the examination based on the surface electromyographic values of the patient's muscles.
Le caratteristiche dell’elettromiografo sono: The characteristics of the electromyograph are:
4 o più ingressi differenziali 4 or more differential inputs
Range canali: /-4mV o /- 0.6mV, a seconda del "guadagno" Channel range: / -4mV or / - 0.6mV, depending on the "gain"
Risoluzione: 12bit Resolution: 12bit
Guadagno: da software 86/70dB Gain: from software 86 / 70dB
CMMR: lOOdB CMMR: 100dB
Taglio inferiore: 15Hz Lower cut: 15Hz
Taglio superiore 700Hz -> OK, da cui una frequenza di campionamento di > 2KHz. 700Hz upper cut -> OK, hence a sampling rate of> 2KHz.
