The JS-Gauge® from SleepLikeMe-Medical GmbH & Co.KG enables individual and stepless 3D adjustment of the starting position (jaw relation) for the fabrication of mandibular advancement splints (MAD). As the first bite gauge, the JS-Gauge® fulfils all requirements of the highest category D of the American Academy of Dental Sleep Medicine (AADSM) and of the German S1 Guideline - "The mandibular advancement splint (MAD): Application in dental sleep medicine for adults” (AWMF registration number 083-045) .
The JS-Gauge® comes with many advantages and thus sets unprecedented standards in dental sleep medicine:
After applying impression material (A-silicones) to the lateral wing inner areas of the bite fork body, the JS-Gauge® is placed symmetrically in the mouth on the upper teeth. In doing so, the spacer is positioned between the two anterior teeth. The JS-Gauge® becomes securely positioned when the patient bites down and the impression material hardens.
In the process of using the device, the impression material (A-silicones) is filled through the front openings of the bite fork body of the JS-Gauge® in the closed position, without any material flowing into the oral cavity. After hardening of the impression material, the patient's mouth can be opened and the JS-Gauge® sits securely on the upper jaw and is ready for bite aquisition.
The JS-Gauge® ensures a high level of patient comfort during use by the dentist. The minimalist design of the distal part of the JS-Gauge® keeps the palate and pharynx free. This eliminates irritation that could lead to tightness and unwanted reflexes.
During the adjustment of the jaw relation, the JS-Gauge® optimises the orientation for a safe clinical adjustment of the bite position. Thus, the upper jaw front teeth (maxillary anterior teeth) are visible at all times and therefore the mandibular midline and mandibular protrusion can be optimally adjusted. The JS-Gauge® also leaves the posterior teeth in the upper jaw visibly exposed. This allows precise adjustment and checking of the bite block under visual control. The JS-Gauge® therefore helps to find the correct starting position (initial jaw relation of the mandibular advancement splint - UPS) for each clinical situation and for each UPS to be fabricated.
Adjusting the vertical and horizontal support pins of the JS-Gauge® sets the lower jaw in the desired bite position and the two support pins are locked in this position using the two screws. The JS-Gauge® allows continuous adjustment in vertical (bite block), horizontal (protrusion, retrusion) and transversal (lateral deviation) directions. The JS-Gauge® therefore ensures an individual 3D adjustment of the bite position when adjusting the start position.
As soon as the desired bite position is set, impression material (A-silicone) is encoded in the front between the first two upper and lower incisors and the horizontal support pin. The freely visible maxillary and mandibular posterior teeth then allow immediate registration of the bite position with the intraoral scanner. Impression mass between the lateral rows of teeth, removal of the bite fork and trimming with repositioning are completely unnecessary. The JS-Gauge® helps to accelerate the treatment process considerably - with a high level of comfort for the patient and for a completely digital workflow.
In this case too, and as soon as the desired bite position is set, encoding is also carried out laterally between the freely visible maxillary posterior teeth and the mandibular posterior teeth, in addition to the encoding with A-silicone in the front, in the case of analogue registration. After curing and removal of the JS-Gauge® from the mouth, the JS-Gauge is ready to be sent to the dental laboratory for fabrication of the mandibular advancement splint (UPS).
