Tongue crib is a removable applianced placed in the maxillary arch for the purpose of stopping the tongue thrusting habit. This appliance maybe used in patients with mixed dentition or permanent dentition. Tongue crib is attached through a bar to two bands placed on the upper 1st molars. The crib is shaped like a horseshoe with metal bars that prevent the thrusting habit. Tongue crib is known to eliminate habits in about 90% of the patients. (citation needed). Huang et al. published a study in 1990 which stated that patients who achieved a positive overbite during their tongue crib therapy had a good chance of maintaining that overbite after their orthodontic treatment. They credited this change to a change in the posterior positioning of the tongue due to the crib therapy.
Some of the side-effects of using a tongue-crib therapy is that this appliance may trap a lot of food which may cause inflammation around the appliance. In addition, repeated contact of tongue with the appliance may also lead to an imprint on the tongue which will self-resolve once the appliance is removed. It is important to note that this type of therapy will only work in patients who do not have a skeletal open bite tendency. Skeletal open bite tendency may be addressed via surgery or other treatments depending on the severity.
It's a type of appliance which is similar to Nance appliance, but instead of acrylic pad that rests on the anterior palate, this appliance has a plastic roller that patient can use their tongue to break their habit. This appliance is banded to the upper 1st molars and bars extend the appliance to anterior palate where the plastic roller is placed.
The most common treatment for mandibular prognathism is a combination of orthodontics and orthognathic surgery. The orthodontics can involve braces, removal of teeth, or a mouthguard.
The surgery required has led, in some cases, to identity crises in patients, whereby the new facial structure has a negative impact mentally on how the patients perceive themselves.
Preventive maintenance therapy for the oral effects of TDO involve frequent dental cleanings, professional application of desensitizing medication, diet counseling, and oral hygiene instructions in proper home care and maintenance; medicated dental rinses and toothpastes are also prescribed as people suffering from TDO are more prone to oral hard tissue disease and early tooth loss. If restorative dentistry is performed without orthodontics to correct the protrusion of the lower jaw, a dental night guard worn at bedtimes on the upper or lower teeth to protect them from the effects of grinding may be recommended.
In extreme cases, tooth loss is inevitable, and the patient will consult with a prosthodontist to determine tooth replacement options such as dental implants, or partial dentures. There is no cure for TDO, but managing its oral and systemic affects is key to having the most favorable outcome from the disease. As the person affected by TDO ages, increased bone fractures may occur. The person suffering from TDO should watch for any pimple like masses on the gum tissue, pain or soreness in the teeth and gums, broken or chipped teeth, feeling of water in the ear or severe pain in the extremities which could indicate fracture.
The hair, teeth, and skeletal side effects of TDO are lifelong, and treatment is used to manage those effects. A person with TDO has the same life expectancy as a person without TDO. There are no cures or medications used to treat systemic effects of TDO, but medications for the frequent ear and dental infections can be used to manage its symptoms. A team based approach between dental specialists, oral and maxillofacial surgeons, and physicians is necessary for treating the systemic effects and improves the prognosis. It is also recommended for affected individuals to seek counseling to be better able to cope with any psychosocial problems due to oral and facial abnormalities that occur with TDO.
At home, a person suffering from TDO may be instructed to use frequent deep conditioning treatments and low manipulation hair styling to control shedding and hair loss. Clinical treatment involves the use of radiology to determine the effects that TDO has had on the surrounding teeth and bone structures. A series of appointments with the healthcare team are usually necessary to correct TDO abnormalities with treatment duration lasting from several months to through full oral-facial maturation stages.
Endodontic procedures are routinely recommended due to treatdental pulp exposure or periodontal abscess. Maxillofacial surgery may be required to establish a more appropriate mastication, skeletal, and esthetic relationship vertically between the teeth to improve functioning. Esthetic procedures such as dental crown (dentistry) or veneer (dentistry) are often performed to improve the physical look of the teeth and to strengthen the weak enamel caused by TDO.
A child with posterior crossbite should be treated immediately if the child shifts his mandible on closing which is often seen in a unilateral crossbite as mentioned above. The best age to treat a child with crossbite is in their mixed dentition when their palatal sutures have not fused to each other. Palatal expansion allows more space in an arch to relieve crowding and correct posterior crossbite. The correction can include any type of palatal expanders that will expand the palate which resolves the narrow constriction of the maxilla. There are several therapies that can be used to correct a posterior crossbite: braces, 'Z' spring or cantilever spring, quad helix, removable plates, clear aligner therapy, or a Delaire mask. The correct therapy should be decided by the orthodontist depending on the type and severity of the crossbite.
One of the keys in diagnosing the anterior crossbite due to skeletal vs dental causes is diagnosing a CR-CO shift in a patient. An adolescent presenting with anterior crossbite may be positioning their mandible forward into centric occlusion (CO) due to the dental interferences. Thus finding their occlusion in centric relation (CR) is key in diagnosis. For anterior crossbite, if their CO matches their CR then the patient truly has a skeletal component to their crossbite. If the CR shows a less severe class 3 malocclusion or teeth not in anterior crossbite, this may mean that their anterior crossbite results due to dental interferences.
Goal to treat unilateral crossbites should definitely include removal of occlusal interferences and elimination of the functional shift. Treating posterior crossbites early may help prevent the occurrence of Temporomandibular joint pathology.
Unilateral crossbites can also be diagnosed and treated properly by using a Deprogramming splint. This splint has flat occlusal surface which causes the muscles to deprogram themselves and establish new sensory engrams. When the splint is removed, a proper centric relation bite can be diagnosed from the bite.
Preventive and restorative dental care is very important as well as considerations for esthetic issues since the crown are yellow from exposure of dentin due to enamel loss. The main objectives of treatment is pain relief, preserving patient's remaining dentition, and to treat and preserve the patient's occlusal vertical height.
Many factors are to be considered to decide on treatment options such as the classification and severity of AI, the patient's social history, clinical findings etc. There are many classifications of AI but the general management of this condition is similar.
Full-coverage crowns are sometimes being used to compensate for the abraded enamel in adults, tackling the sensitivity the patient experiences. Usually stainless steel crowns are used in children which may be replaced by porcelain once they reach adulthood. These aid with maintaining occlusal vertical dimension.
Aesthetics may be addressed via placement of composite or porcelain veneers, depending on patient factors eg age. If the patient has primary or mixed dentition, lab-made composite veneers may be provided temporarily, to be replaced by permanent porcelain veneers once the patient has stabilized permanent dentition. The patient's oral hygiene and diet should be controlled as well as they play a factor in the success of retaining future restorations.
In the worst-case scenario, the teeth may have to be extracted and implants or dentures are required. Loss of nerves in the affected teeth may occur.
Crowding of the teeth is treated with orthodontics, often with tooth extraction, clear aligners, or dental braces, followed by growth modification in children or jaw surgery (orthognathic surgery) in adults. Surgery may be required on rare occasions. This may include surgical reshaping to lengthen or shorten the jaw (orthognathic surgery). Wires, plates, or screws may be used to secure the jaw bone, in a manner similar to the surgical stabilization of jaw fractures. Very few people have "perfect" alignment of their teeth. However, most problems are very minor and do not require treatment.
Literature states that very few crossbites tend to self-correct which often justify the treatment approach of correcting these bites as early as possible. Only 0–9% of crossbites self-correct. Lindner et al. reported that in a 50% of crossbites were corrected in 76 four year old children.
Management of teeth with PFE can include extractions of affected teeth, followed by orthodontic space closure or placement of a prosthetic implant with a bone graft. This option can only be applied to a single tooth that is affected. If multiple teeth are affected then, a segmental osteotomy may be performed to bring the entire segment into occlusion. However, minimal success has been shown following this procedure. These teeth usually are "non-responsive" to the orthodontic force and studies have shown that ankylosis of these teeth can occur if force applied.
Also called myofunctional therapy, the basic treatment aims of orofacial myofunctional therapist is to reeducate the movement of muscles, restore correct swallowing patterns, and establish adequate labial-lingual postures. An interdisciplinary nature of treatment is always desirable to reach functional goals in terms of swallowing, speech, and other esthetic factors. A team approach has been shown to be effective in correcting orofacial myofunctional disorders. The teams include an orthodontist, dental hygienist, certified orofacial myologist, general dentist, otorhinolaryngologist, and a speech-language pathologist.
Treatment of condylar resorption is controversial. Orthognathic surgery may be done to reconstruct and stabilize the condyles and disc of the temporomandibular joint. Anti-infammatory medication is also used to slow the resorption process. Orthodontics may be used to treat the occlusion. Arthrocentesis, and arthroscopic surgery are also sometimes used to treat disc displacement and other symptoms.
To establish appropriate alignment and occlusion, the sizes of upper and lower front teeth, or upper and lower teeth in general, need to be proportional. Inter-arch tooth size discrepancy (TSD) is defined as a disproportion in the mesio-distal dimensions of teeth of opposing dental arches, which can be seen in 17% to 30% of orthodontic patients.
Treatment and prognosis of macroglossia depends upon its cause, and also upon the severity of the enlargement and symptoms it is causing. No treatment may be required for mild cases or cases with minimal symptoms. Speech therapy may be beneficial, or surgery to reduce the size of the tongue (reduction glossectomy). Treatment may also involve correction of orthodontic abnormalities that may have been caused by the enlarged tongue. Treatment of any underlying systemic disease may be required, e.g. radiotherapy.
Prosthetic replacement of missing teeth is possible using dental implant technology or dentures. This treatment can be successful in giving patients with anodontia a more aesthetically pleasing appearance. The use of an implant prosthesis in the lower jaw could be recommended for younger patients as it is shown to significantly improve the craniofacial growth, social development and self-image. The study associated with this evidence worked with individuals who had ectodermal dysplasia of varying age groups of up to 11, 11 to 18 and more than 18 years. It was noted that the risk of implant failure was significantly higher in patients younger than 18 years, but there is significant reason to use this methodology of treatment in those older. Overall the use of an implant-prosthesis has a considerable functional, aesthetic and psychological advantage when compared to a conventional denture, in the patients.
Treatment for uncontrolled tongue thrust requires habit retraining in conjunction with a dental appliance.
Medication is the main method of managing pain in TMD, mostly because there is little if any evidence of the effectiveness of surgical or dental interventions. Many drugs have been used to treat TMD pain, such as analgesics (pain killers), benzodiazepines (e.g. clonazepam, prazepam, diazepam), anticonvulsants (e.g. gabapentin), muscle relaxants (e.g. cyclobenzaprine), and others. Analgesics that have been studied in TMD include non-steroidal anti-inflammatory drugs (e.g. piroxicam, diclofenac, naproxen) and cyclo-oxygenase-2 inhibitors (e.g. celecoxib). Topical methyl salicylate and topical capsaicin have also been used. Other drugs that have been described for use in TMD include glucosamine hydrochloride/chondroitin sulphate and propranolol. Despite many randomized control trials being conducted on these commonly used medications for TMD a systematic review carried out in 2010 concluded that there was insufficient evidence to support or not to support the use of these drugs in TMD. Low-doses of anti-muscarinic tricyclic antidepressants such as amitriptyline, or nortriptyline have also been described. In a subset of people with TMD who are not helped by either noninvasive and invasive treatments, long term use of opiate analgesics has been suggested, although these drugs carry a risk of drug dependence and other side effects. Examples include morphine, fentanyl, oxycodone, tramadol, hydrocodone, and methadone.
Botulinum toxin solution ("Botox") is sometimes used to treat TMD. Injection of botox into the lateral pterygoid muscle has been investigated in multiple randomized control trials, and there is evidence that it is of benefit in TMD. It is theorized that spasm of lateral pterygoid causes anterior disc displacement. Botulinum toxin causes temporary muscular paralysis by inhibiting acetylcholine release at the neuromuscular junction. The effects usually last for a period of months before they wear off. Complications include the creation of a "fixed" expression due to diffusion of the solution and subsequent involvement of the muscles of facial expression, which lasts until the effects of the botox wear off. Injections of local anesthetic, sometimes combined with steroids, into the muscles (e.g. the temoralis muscle or its tendon) are also sometimes used. Local anesthetics may provide temporary pain relief, and steroids inhibit pro-inflammatory cytokines. Steroids and other medications are sometimes injected directly into the joint (See Intra-articular injections).
In disease states, maxillary prognathism is associated with Cornelia de Lange syndrome; however, so-called false maxillary prognathism, or more accurately, retrognathism, where there is a lack of growth of the mandible, is by far a more common condition.
Prognathism, if not extremely severe, can be treated in growing patients with orthodontic functional or orthopaedic appliances. In adult patients this condition can be corrected by means of a combined surgical/orthodontic treatment, where most of the time a mandibular advancement is performed. The same can be said for mandibular prognathism.
Many different medications have been used to treat bruxism, including benzodiazepines, anticonvulsants, beta blockers, dopamine agents, antidepressants, muscle relaxants, and others. However, there is little, if any, evidence for their respective and comparative efficacies with each other and when compared to a placebo. A systematic review is underway to investigate the evidence for drug treatments in sleep bruxism.
Specific drugs that have been studied in sleep bruxism are clonazepam, levodopa, amitriptyline, bromocriptine, pergolide, clonidine, propranolol, and l-tryptophan, with some showing no effect and others appear to have promising initial results; however, it has been suggested that further safety testing is required before any evidence-based clinical recommendations can be made. When bruxism is related to the use of selective serotonin reuptake inhibitors in depression, adding buspirone has been reported to resolve the side effect. Tricyclic antidepressants have also been suggested to be preferable to selective serotonin reuptake inhibitors in people with bruxism, and may help with the pain.
Treatment for bruxism revolves around repairing the damage to teeth that has already occurred, and also often, via one or more of several available methods, attempting to prevent further damage and manage symptoms, but there is no widely accepted, best treatment. Since bruxism is not life-threatening, and there is little evidence of the efficacy of any treatment, it has been recommended that only conservative treatment which is reversible and that carries low risk of morbidity should be used. The main treatments that have been described in awake and sleep bruxism are described below.
Treatment is surgical, and usually is able to be performed once life-threatening injuries are stabilized, to allow the patient to survive the general anesthesia needed for invasive orthopedic restructuring. First a "frontal bar" is used, which refers to the thickened frontal bone above the frontonasal sutures and the superior orbital rim. The facial bones are suspended from the bar by open reduction and internal fixation with titanium plates and screws, and each fracture is fixed, first at its superior attachment to the bar, then at the inferior attachment to the displaced bone. For stability, the zygomaticofrontal suture is usually replaced first, and the palate and alveolar ridge are usually fixed last. Finally, after the horizontal and vertical maxillary buttresses are stabilized, the orbital fractures are fixed last.
TMD can be difficult to manage, and since the disorder transcends the boundaries between several health-care disciplines — in particular, dentistry and neurology, the treatment may often involve multiple approaches and be multidisciplinary. Most who are involved in treating and, researching TMD now agree that any treatment carried out should not permanently alter the jaw or teeth, and should be reversible. To avoid permanent change, over-the-counter or prescription pain medications may be prescribed.
No treatment is needed. If a stork bite lasts longer than 3 years, it may be removed using laser surgery.
The adaptation from nasal to mouth breathing takes pace when changes such as chronic middle ear infections, sinusitis, allergic rhinitis, upper airway infections, and sleep disturbances (e.g., snoring) take place. In addition, mouth breathing is often associated with a decrease in oxygen intake into the lungs. Mouth breathing can particularly affect the growing face, as the abnormal pull of these muscle groups on facial bones slowly deforms these bones, causing misalignment. The earlier in life these changes take place, the greater the alterations in facial growth, and ultimately an open mouth posture is created where the upper lip is raised and the lower jaw is maintained in an open posture. The tongue, which is normally tucked under the roof of the mouth, drops to the floor of the mouth and protrudes to allow a greater volume of air intake. Consequently, an open mouth posture can lead to malocclusions and problems in swallowing. Other causes of open-mouth posture are weakness of lip muscles, overall lack of tone in the body or hypotonia, and prolonged/chronic allergies of the respiratory tract. A.union
Overbite medically refers to the extent of vertical (superior-inferior) overlap of the maxillary central incisors over the mandibular central incisors, measured relative to the incisal ridges.
The term overbite does not refer to a specific condition, nor is it a form of malocclusion. Rather an absent or excess overbite would be a malocclusion. Normal overbite is not measured in exact terms, but as a proportion (approximately 30–50% of the height of the mandibular incisors) and is commonly expressed as a percentage.
