CPAP compliance can be challenging under ideal conditions. Not surprisingly, the quality of sleep among soldiers can be a shambles during combat deployment. “Research shows that chronic low-level sleep deprivation impairs reasoning, decision-making, and slows reaction time. You don’t want that in a combat-deployed troop.” Beyond the obvious benefits of reduced accidents and convenient placement in a ruck sack, they found that even post traumatic stress disorder (PTSD) may be affected by poor sleep. Even in cases of clearly identified sleep apnea, most troops could not afford to give up pack space for CPAP devices and batteries.
Armed with findings from one of the largest patient populations to date, Army researchers found that adjustable OAs are nearly as effective as CPAP treatment for patients with mild to moderate OSA, and are more effective than fixed oral appliances—particularly in patients with moderate to severe OSA.
The military is interested in the potential of adjustable OAs, also called mandibular advancement devices, as alternatives to CPAP systems since some active duty service members deploy to remote environments where electricity is not always available. In these cases, reliance on CPAP may result in duty restrictions or separation from service. “Adjustable OAs would eliminate duty assignment limitations associated with CPAP, allowing soldiers to travel to remote areas as needed,” adds Lettieri.

Treatment of children with increased overjet using functional appliances reduces the probability of needing orthognathic surgery later. The skeletal effect of these appliances appears to result from various phenomena: remodeling and relocation of the glenoid fossa accelerated and enhanced condylar growth and neuromuscular adaptation.
The purpose of this study was to determine the effect of the T4K, a prefabricated functional appliance, on the transverse and anterior-height dimensions of the maxillary and mandibular dental arches. Dimensions before and after treatment were measured on the sample, then, natural growth was subtracted from the treatment effects and compared with twice the error of the method. A clinically sign cant increase of both dimensions was observed in the maxilla and mandible when Class II malocclusion patients were treated with the T4K.
The control group consisted composed of 32 girls and 28 boys. Data from clinical histories of the patients in the treated group were used to determine age at the beginning and at the end of treatment, as well as the duration of treatment. Each patient in the treated group had a matched control from normative data with respect to age, sex and observation period.

Orthodontic intervention in the early mixed dentition: A prospective, controlled study on the effects of the eruption guidance appliance
This study was started to investigate the effects of orthodontic treatment in the early mixed dentition with the eruption guidance appliance. Treatment in the early mixed dentition with the eruption guidance appliance is an effective method to restore normal occlusion and eliminate the need for further orthodontic treatment.
The treatment group was derived from the entire 1992 and 1993 age cohorts in Jalasjärvi (population, 9000) and the 1992 age cohort in Kurikka (population, 11,000). All children were screened in the late deciduous dentition, and a full clinical examination was made at the onset of the mixed dentition period of those who were considered to potentially need treatment.
The study started with a total of 315 children. Of them, 33 were treated with other appliances, mainly the quad-helix, and they were excluded from the study sample. In 27 cases, the child or the family refused orthodontic treatment. Treatment with an erup- tion guidance appliance was started in 255 children. During the treatment, 12 children moved to another municipality and could not complete the treatment; their records were excluded from the analysis. Of the remaining 243 children, 167 completed the treatment successfully.
