BACKGROUND: A rodent occlusal hypofunction model has been widely established in jawbone-related studies. However, the effects of occlusal stimuli, with total elimination of molar contacts, and its rehabilitation on mandibular remodeling remain unclear. MATERIALS AND METHODS: Forty-eight 5-wk-old Sprague-Dawley male rats were used. Twenty-four experimental rats underwent occlusal hypofunction by insertion of a bite-raising appliance. Twenty-four rats received no treatment (control group)...

BACKGROUD: Normal occlusion is very important for physiological structure of mandible. However, the details of influences of occlusal hypofunction and its recovery on the three-dimensional architecture of mandibular alveolar bone in growing rats are still lacking. MATERIALS AND METHODS: Forty-eight growing male Sprague-Dawley rats were randomly divided into normal (n = 24), hypofunctional (n = 12), and recovery (n = 12) groups. The hypofunction group was developed by inserting a bite-raising appliance between the maxillary and mandibular incisors of the rats...

OBJECTIVES: To investigate the effects of long-term, artificially created, hypofunctional occlusion and its recovery on the morphology of rat molar roots. MATERIAL AND METHODS: Eighteen 5-week-old Wistar-strain male rats were randomly divided according to their periodontal conditions into normal, hypofunctional, and recovery groups (n = 6 in each). In the experimental hypofunctional and recovery groups, a bite-raising appliance was set to produce hypofunction at the molar region...

AIM: Delaire-type facemask is still the appliance of choice for non surgical paediatric Class III treatment. However, it entails great aesthetical problems and is totally dependent on patient compliance. A new modified maxillary protractor was then designed: it is monomaxillary, fixed, implant-supported, aesthetically pleasing and it does not require patient compliance. The aims of this study were to evaluate the clinical use and analyse the effects of a new appliance called Fixed Maxillary Protractor...

It has recently been suggested that wearing a maxillary occlusal splint (i.e. a hard acrylic resin dental appliance that covers the occlusal surfaces of the maxillary dentition and that is being indicated for the treatment of, e.g. temporomandibular pain) may be associated with a risk of aggravating obstructive sleep apnoea (OSA). The present study tested the hypothesis that raising the bite without mandibular protrusion in OSA patients is associated with an increase in the apnoea-hypopnoea index (AHI). Eighteen OSA patients (13 men; 49·5 ± 8·1 years old) received a mandibular advancement device in 0% protrusion of the mandible (0%MAD)...

Previous studies have investigated the effects of increasing the occlusal vertical dimension (OVD) with an oral appliance on masticatory muscle EMG activity during oral behaviours in humans and animals. The present study investigated whether a short-term and reversible increase in OVD, followed by a reduction in OVD to the normal level, resulted in a time-correlated change in the EMG activities of the masseter and digastric muscles during chewing. To do this, a guinea pig model in which an increased OVD was established with natural tooth contacts was used...

Lesch-Nyhan syndrome (LNS) is an X-linked disorder originating from deficiency of the enzyme hypoxanthine guanine phosphoribosyl transferase. It is characterized by neurological manifestations, including the dramatic symptom of compulsive self-mutilation, which results in destruction of oral and perioral tissues. Several drug trials have been administered to improve the severe self-destructive behaviour, with questionable effectiveness. Invasive treatment approaches, such as extraction of teeth and orthognathic surgery, have been suggested with variable success...

The purpose of this study was to quantify the impact of oral screen (OS) application on intra-oral pressure characteristics in three malocclusion groups. Fifty-six randomly recruited participants (26 males and 30 females) who met the inclusion criteria of either an Angle Class I occlusal relationships or Angle Class II1 or II2 malocclusions, were assigned by dentition to group I (n = 31), group II1 (n = 12), or group II2 (n = 13). Two 3 minute periods of intra-oral pressure monitoring were conducted on each participant, using two different oral end fittings connected to a piezo-resistive relative pressure sensor: (1) a flexible OS and (2) a small-dimensioned air-permeable end cap (EC), which was placed laterally in the premolar region, thus recording intra-oral pressure independent of the influence of the OS...

OBJECTIVES: To compare a mandibular advancement splint to a control bite raising appliance in the treatment of snoring with or without mild obstructive sleep apnoea syndrome. DESIGN: A prospective two-treatment randomised cross-over clinical trial. SETTING: Single centre secondary care Dental Hospital. PARTICIPANTS: Fifty-two subjects (36 men, 16 women) diagnosed with non-apnoeic snoring or mild obstructive sleep apnoea syndrome (apnoea/hypopnoea index < or =15 events/h), were recruited from Departments of Respiratory Medicine and ENT surgery, Newcastle upon Tyne Hospitals NHS Foundation Trust...

OBJECTIVE: To examine changes in gravity fluctuation caused by experimentally altering the area of occlusal contact. MATERIALS AND METHODS: Subjects consisted of 15 adult Japanese males with normal stomatognathic function, no missing teeth except for the third molars, and equivalent occlusal contact in the anterior and bilateral posterior regions. Silicon biteplates fabricated for each subject to evaluate gravity fluctuation in relation to changes in occlusal contact area were as follows: RP(-)-OC(+) (entire occlusal surface covered in centric occlusion); RP(+)-OC(+) (entire occlusal surface covered with bite slightly raised); Ant or Pos/RP(+)-OC(+) (anterior or posterior region selectively covered); and RP(+)-OC(-) (only retromolar pads covered, no occlusal coverage)...

Previous studies analysed the temporal changes of occlusal vertical dimension (OVD) with natural molar tooth contacts in bite-raised guinea pigs and found that the OVD is strictly maintained in the growing guinea pigs. Since the OVD is considered to be the influencing factor for performing mastication, we hypothesised that a control of the OVD is integrated with maintenance of an appropriate chewing behavior. In young adult guinea pigs with or without bite-raised treatment, the OVD was measured by micro-CT and stable chewing movements were recorded during 11 days after the removal of the bite-raising appliance...

BACKGROUND AND OBJECTIVE: Some patients with open bite who have been treated with combined fixed orthodontic appliances and bimaxillary osteotomy relapse in the vertical dimension after the end of treatment following initially successful correction of the vertical dimension. The aim of this study was to identify those parameters that raise the tendency to relapse. MATERIALS AND METHODS: Nineteen patients who underwent combined treatment using fixed orthodontic appliances and bimaxillary osteotomy due to open bite (overbite < 0 mm), were examined and documented at least 2 years after surgery...

The purpose of this study was to demonstrate how short-term wearing of an oral appliance (OA) with equal bite-raising distance but with varying protrusions affects occlusal force, contact area and load center. Twelve young healthy volunteers participated. With the appliance, the mandible was protruded 0%, 45%, 60% and 75% of maximum protrusion capacity, with 10 mm bite-raising between the first molars. The occlusal force, contact area and load center at maximum voluntary clenching were measured before wearing the OA, at 1 h, 3 h and 6 h during wearing, and 1 h after removal...

PURPOSE: Little information is available on the mandibular protrusion with oral appliances (OA) for the treatment of obstructive sleep apnea syndrome (OSAS) to have no negative effect on the stomatognathic system. The purpose of the current study was to assess the influence of mandibular protrusion on occlusion to fabricate the appropriate OA. METHODS: Twelve healthy adults were selected. With the OA in position, the mandible was advanced 0, 45, 60, 75% of maximum protrusion capacity; bite raising distance between the first molars was 5mm (OA5-0, 45, 60 and 75)...

This study investigates the structural adaptation of the mandibular bone when subjected to different masticatory functional and mechanical demands during growth. The effect of two experimental factors, the insertion of a bite block and the alteration of food consistency, on the bone mineral density (BMD) of the mandible was investigated in growing rats. Fifty-two male albino rats were divided into two equal groups, fed with either the standard hard diet or soft diet, at the age of four weeks. After two weeks, half the animals in both groups had their upper molars fitted with an upper posterior bite block...

Functional appliances displace the mandible forward and/or downward, causing a stretching of the orofacial soft tissues, muscles included. The resulting forces are directly or indirectly transmitted to the underlying dento-skeletal tissues. The hypothesis underlying the present investigation was that the insertion of a bite-opening appliance influences the lateral morphology of the rat mandible during growth, and that, moreover, this influence depends on the masticatory functional demands. One-hundred and four 4-wk-old male albino rats were divided into two groups, fed a hard and soft diet, respectively...

Dahl partial bite-raising appliances have been used over the past 30 years for the management of occlusal tooth tissue loss, particularly in patients who have lost normal occlusal vertical dimension. The more recent use of Dahl-type appliances for individual teeth has changed the restorative management of patients with localized anterior tooth erosion. The Dahl treatment principle can be applied to those patients with and without the loss of occlusal vertical dimension. Palatal bite-raising platforms can be used to re-establish anterior tooth guidance for disocclusion of the posterior teeth without occlusal interferences...
