PURPOSE: To compare the efficacy of twin-block (i.e., allows mouth opening) and fixed (i.e., maintains mouth closure) mandibular advancement splints (MASs) for the treatment of obstructive sleep apnea-hypopnea syndrome (OSA). MATERIALS AND METHODS: From 2011 to 2013, 23 patients with OSA in the twin-block group, and from 2013 to 2015, 29 patients in the fixed MAS group were included. All patients underwent polysomnography before and after 3 months of treatment. The two sets of polysomnographic and cephalometric variables were compared...

BACKGROUND: Although it is common clinical practice to treat children with Juvenile Idiopathic Arthritis (JIA) with functional appliances, the scientific evidence for this is limited. The aim of this study was to study the histologic effects of mandibular protrusion splints in temporomandibular joint (TMJ) arthritis in rabbits. METHODS: Twenty-eight ten-week old New Zealand white rabbits were randomly divided into four groups: AO (TMJ arthritis, no splint), AS (TMJ arthritis, mandibular splint advancement), OS (no arthritis, mandibular splint advancement) and OO (no arthritis, no splint)...

OBJECTIVE: The objective of the study is to compare skeletal and dental changes in class II patients treated with fixed functional appliances (FFA) that pursue different biomechanical concepts: (1) FMA (Functional Mandibular Advancer) from first maxillary molar to first mandibular molar through inclined planes and (2) Herbst appliance from first maxillary molar to lower first bicuspid through a rod-and-tube mechanism. MATERIALS AND METHODS: Forty-two equally distributed patients were treated with FMA (21) and Herbst appliance (21), following a single-step advancement protocol...

The aim of this prospective study was to correlate the postoperative 3-dimensional facial changes in skeletal class III deformity with sagittal jaw movements in 84 patients who had been treated by one piece Le Fort I maxillary advancement only (n=18), mandibular setback only (n=38), or both procedures (n=28). At the times of evaluation before and six months after operation all patients had fixed orthodontic appliances. Soft tissue changes were evaluated on optical 3-dimensional scans, while lateral cephalograms were superimposed to assess sagittal jaw movements...

Obstructive sleep apnea syndrome (OSAS) is associated with several sleep disorders and sleep-related problems. Therefore, the aim of this study was to compare the effects of a mandibular advancement device (MAD) with those of nasal continuous positive airway pressure (nCPAP) on self-reported symptoms of common sleep disorders and sleep-related problems in mild and moderate OSAS patients. In this randomized placebo-controlled trial sixty-four OSAS patients (52.0± 9.6 years) were randomly assigned to an MAD, nCPAP or an intra-oral placebo appliance in a parallel design...

OBJECTIVE: In the treatment of obstructive sleep apnea (OSA) with an oral appliance (OA), there is no gold standard method to fine-tune the mandibular advancement. This study aimed to analyze the effect of gradual increment of mandibular advancement on the evolution of the apnea-hypopnea index (AHI). METHODS: OSA patients were recruited from a sleep unit. All treatments started with an oral appliance without mandibular advancement. After two weeks, the AHI was assessed with respiratory polygraphy...

OBJECTIVE: To investigate the proportion of skeletal/dentoalveolar components for correction of Class II malocclusion in relation to the pubertal growth peak (PGP) among patients treated with the mandibular advancement locking unit (MALU) appliance. MATERIALS AND METHODS: We conducted a retrospective study of 27 orthodontic patients (age range: 12-18 years; mean age 14.9 years) with skeletal Class II Division 1 malocclusion who were treated with the MALU appliance until they reached Class I occlusion with overjet and overbite within normal range...

OBJECTIVES: To evaluate the dentoskeletal changes associated with long-term and continuous mandibular advancement device (MAD) use in sleep-related breathing disorder patients. METHODS: Cephalometric measurements and three-dimensional model analysis were performed at baseline and after 3.5 ± 1.1 years in 20 snoring and obstructive sleep apnoea patients treated with the Silensor® appliance. Intra-group differences were compared using paired t-test or Wilcoxon signed-rank test...

OBJECTIVE: To compare efficacy, side effects, patient compliance, and preference between two types of custom-made mandibular advancement appliances (MAAs) in the treatment of patients with mild to moderate obstructive sleep apnea (OSA). METHODOLOGY: This prospective, randomized, crossover study of 12 patients with mild to moderate OSA compared a titratable and a non-titratable MAA. Each patient was fitted with both appliances in a random order with a washout period of two weeks...

INTRODUCTION: The Herbst appliance has been used in the treatment of Class II malocclusions with deficient mandibles. Various protocols, including different durations of the orthopedic treatment phase and stepwise advancement of the mandible, have been advocated for increasing the orthopedic effects. The objective of this study was to investigate the skeletal and dental changes in patients treated with a reinforced banded Herbst appliance for an extended duration and fixed appliance therapy...

A combination of abnormal anatomy and physiology of the upper airway can produce its repetitive narrowing during sleep, resulting in obstructive sleep apnea (OSA). Treatment of sleep-breathing disorder ranges from lifestyle modifications, upper airway surgery, continuous positive airway pressure (CPAP) to the use of oral appliances. A proper treatment selection should be preceded by thorough clinical and instrumental examinations. The type and number of specific oral appliances are still growing. The mandibular advancement appliance (MAA) is the most common type of a dental device in use today...

BACKGROUND: During archaeological excavation, carried out in the S. Francesco Monastery at Lucca (Tuscany, Italy), a golden dental appliance was discovered. The prosthesis was found, together with commingled human remains, in the collective tomb of the aristocratic family of the Guinigi, a powerful family who governed Lucca from 1392 until 1429. The exact archaeological dating of the prosthesis was not possible, but some elements suggest a dating to the beginning of the 17th century. PURPOSE: Aim of the paper is to study and describe the dental appliance trough a multidisciplinary approach...

OBJECTIVES: Purpose of the present study was to determine and compare possible changes in the dimensions of the pharyngeal airway, morphology of the soft palate, and position of the tongue and hyoid bone after single-step or stepwise mandibular advancement using the Functional Mandibular Advancer (FMA). PATIENTS AND METHODS: The sample included 51 peak-pubertal Class II subjects. In all, 34 patients were allocated to two groups using matched randomization: a single-step mandibular advancement group (SSG) and a stepwise mandibular advancement group (SWG)...

OBJECTIVES: The purpose of this work was to employ both cephalometric and tensor analysis in characterizing the skeletal changes experienced by patients with Angle Class II/1 malocclusion during functional orthodontic treatment with the functional regulator type II. METHODS: A total of 23 patients with Class II/1 malocclusion based on lateral cephalograms obtained before and after treatment with the functional regulator type II were analyzed. Another 23 patients with Angle Class II/1 malocclusion who had not undergone treatment were included as controls...

BACKGROUND: Sleep-Disordered Breathing (SDB) varies from habitual snoring to partial or complete obstruction of the upper airway and can be found in up to 10% of children. SDB can significantly affect children's wellbeing, as it can cause growth disorders, educational and behavioral problems, and even life-threatening conditions, such as cardiorespiratory failure. Adenotonsillectomy represents the primary treatment for pediatric SDB where adeno-tonsillar hypertrophy is indicated. For those with craniofacial anomalies, or for whom adenotonsillectomy or other treatment modalities have failed, or surgery is contra-indicated, mandibular advancement splints (MAS) may represent a viable treatment option...

BACKGROUND: Although many orthodontists have no doubts about the effectiveness of functional appliances for mandibular advancement, the impact on the temporomandibular joint (TMJ) is still in dispute. The objective of this systematic review is to examine the main effects on the TMJ of using functional appliances, both in healthy patients and in patients with a pre-existing disorder. MATERIAL AND METHODS: A systematic review of the literature was conducted in accordance with the PRISMA guidelines...
