The amount of mandibular advancement varies from individual to individual,
but it is usually effective up to 50~70%.
Multiple adjustments required to minimize discomfort
A review of over 40 papers on the effectiveness of oral appliances
from 1982-2002 found that87% of snorers
with sleep apnea had a 55.7% reduction in their respiratory disturbance index (RDI).

Initially, about 2/3 of the maximum possible forward movement may be attempted.
Allowing free mandibular movement, both vertically and laterally,
can reduce the risk of reduces the risk of jaw arthropathy
and improves patient compliance.
For detachable appliances, symptomatic bruxism may result in fracture of the appliance.
Assess discomfort for the first week or two as an adjustment period,
indirectly through a sleep partner to determine if symptoms have decreased.
If there is a lack of improvement, adjust the mandible to advance in 1 to 2 mm increments.

Oral appliance therapy can be a good alternative to CPAP therapy with comparable therapeutic benefits with fewer side effects and discomfort, making it a good alternative to CPAP therapy.

guidelines for oral appliance therapy for patients with OSA.
We will cover the types, mechanisms, effects, and use of oral appliance therapy.
The severity of OSA is based on the Respiratory Distress Index
RDI 5-15 (mild), 15-30 (moderate), and 30 or more (severe).
Oral appliances have a greater therapeutic effect the more the mandible is moved forward, gradually increasing the amount of movement to achieve optimal results
with minimal side effects.
optimal treatment results with minimal side effects.
Typically, 6 to 10 mm or 50 to 75% of the maximum anterior movement is achieved.
Increasing the vertical opening should be minimized as it has been shown to be counterproductive in opening the upper airway.
Side effects include jaw joint pain, myofascial pain, and tooth pain,
excessive salivation, jaw joint sounds, dry mouth, and gingival irritation.
Most are temporary, and TMJ symptoms decrease over time.
The majority of patients resolve their symptoms within 6 to 12 months.
The degree of bite change is usually negligible,
In fact, many patients are unaware of their bite changes,
and the vast majority of patients are satisfied with the
The positive effects of treatment outweigh any side effects associated with bite
