This article describes the use of a flexible force module (the Jasper Jumper) that can be incorporated into existing fixed appliances to correct various types of sagittal malocclusion. Essentially the spring mechanism described in this article is a modification of the original bite jumping mechanism of Herbst. The flexible spring module provides greater freedom of mandibular movement than is possible with the more rigid mechanism of the Herbst appliance. The facial musculature applies force through these modules to the anchor points to produce a variety of treatment effects. The treatment effects produced by the module mimic those previously described for the Herbst appliance and include posterior movement of the maxillary buccal segments and anterior movement of the mandible or mandibular dentition or both. Specifics of the clinical management of this modular system are discussed, including anchorage preparation and torque application, as well as the methods of anchoring, activating and reactivating the modules.
The effect of the Jasper Jumper appliance (American Orthodontics, Sheboygan, Wis.) on the dentofacial complex was studied in 17 consecutive growing patients who had Class II, Division 1 malocclusions. Lateral cephalograms taken before treatment and immediately after removal of the Jumpers were analyzed according to the method of Pancherz. The following results were found: (1) Class I occlusal relationships were achieved in all patients in an average treatment time of 6 months. (2) The correction of the Class II malocclusion was a result of skeletal (40%) and dental (60%) changes. (3) Skeletal Class II correction was predominantly restricted to the mandible. (4) The dentoalveolar part of total molar relationship correction took place to the same extent in both jaws, whereas in overjet correction the maxillary dental changes outweighed the mandibular changes by far. (5) When compared with normal growth changes (Bolton standards), treatment with Jasper Jumpers distalizes the upper dentition and moves the lower teeth mesially. Mandibular growth seems to be increased to some extent. It was concluded that treatment with the Jasper Jumper appliance presents an effective method to correct Class II malocclusion in growing patients.
These clinical guidelines, which have been reviewed and approved by the Board of Directors of the American Sleep Disorders Association (ASDA), provide recommendations for the practice of sleep medicine in North American with regards to the use of oral appliances for the treatment of snoring and obstructive sleep apnea. Oral appliances have been developed for the treatment of snoring and have been applied to the treatment of obstructive sleep apnea, a syndrome associated with morbidity. Based on a review of the relevant scientific literature, the Standards of Practice Committee of the ASDA has developed guidelines describing the use of oral appliances for the treatment of snoring and obstructive sleep apnea in adults.
