RESUMEN
@#BACKGROUND: Microtia is often associated with hearing loss and patients typically require treatment for hearing impairment and surgical ear reconstruction. The occurrence of microtia is of public health importance in part due to the psychosocial sequelae, including the stigma associated with malformations of the ear and the burden of undergoing multiple surgeries In addition, greater than 90% of individuals with microtia experience conductive hearing loss on the affected side. Although children with microtia-anotia are at a greater risk of delayed language development and attention deficit disorders. METHODS: Our study has a 173 childrens from the UB city and countryside. 23 children has a bilateral microtia and anotia. 6 patient wearing BAHA soft band from 6 months age. 150 patients have an unilateral microtia. Microtia was found more commonly in males, unilateral and right sided. Even children with bilateral microtia may have wearing BAHA soft band before 6 months age. RESULTS: External ear malformations are more commonly found in males. Sex ratio 2:1. From other studies right ear malformations are more common in male children. In our study children who have bilateral ear abnormalities wearing BAHA softband and language therapy from 6 months age to able to have normal language development. Children who had surgical treatment and using hearing aid can have normal social life and increased quality of life. CONCLUSION: Early screening in children who have external ear malformation, monitoring language development, wearing BAHA softband from 2 months age who have bilateral ear malformation and one ear affected other one is normal children wear BAHA softband increases children speech and language development.
RESUMEN
@#BACKGROUND. The Dahl Concept refers to the relative axial tooth movement that is observed when a localized restorations are placed in supra-occlusion in dental hard tissue worn anterior area and posterior full arch occlusal contacts re-establishes over a period of time irrespective of age and gender. The literature reports that the objectives of the Dahl concept are achieved in the majority of cases (94%-100%). Some minor and transient adverse events, such as initial difficulty with mastication could develop. If dental arch is crowded and some of the teeth are pushed away, they tends to be pushed more even they were visually aligned by a heavy preparation under the ceramic restorations such as crowns and veneers. To avoid these costly and teeth-harmful treatment options for patients with anterior crowding and who wants straighter and beautiful looking teeth, we use a conservative approach of Align+Bleach+Bonding technique. MATEREALS AND METHOD. For tooth alignment we used Inman Aligner, Clear Aligner and Clear Smile Braces (fixed ceramic braces with super elastic Ni-Ti wires) or their combination. After short orthodontics a Dahl concept was applied to improve patients’ functional occlusion and anterior guidance. A “free-hand” and “no-any-drill” composite restoration technique was used to restore worn anterior teeth. For proper orthodontic diagnosis, assessment and treatment planning Spacewise analysis and Digital Caliper measurement were performed using models, their digital scans and intra/extraoral photos. We use Inman Orthodontic Lab in Florida for Inman Aligner fabrication and IAS Laboratory in London for Clear smile braces set up. Clear aligners (Scheu Dental, Germany) are planned and fabricated at the Digital Dental Office’s Clear Aligner certified laboratory. All treatments are start only after thorough diagnostic analysis, case discussion and acceptance from technical experts and orthodontists from UK, USA and Germany and acceptance of planned results from the patients. A course of home bleaching was then performed followed by resin bonding of anterior teeth edges to stabilize anterior guidance. RESULTS. More than 200 cases of upper and lower anterior crowding have been treated in comparably short period of time. From those we are introducing 3 different cases which were treated using above mentioned three appliances as an example. Average orthodontic treatment lasted 8-16 weeks depending on degree of crowding and type of appliances used. The arch crowding were less than 4 mm in all of them. No any teeth were extracted. After orthodontic treatment patients had double retentions (fixed+clear retainers). Dahl concept was performed in patients with anterior attrition and few patients experienced minor difficulty with chewing for their first week only. To control results of molar extrusion we measured space between occlusal surfaces of opposing molars in the SAM 3 articulator positioned in the centric relation. CONCLUSION. In order to get a long term proper stability of dento-facial function with a bonus of beautiful smile the concept of keeping own teeth and its structure became essential in cosmetic and restorative dentistry. The good thing of Dahl technique is its simplicity if it is done properly and its cost effectiveness. And as it was described the edge bonding itself could be a permanent retainer which prevents a future relapse in ortho-aligned teeth. Moreover patients were highly satisfied due to fast alignment, opportunity of keeping their teeth untouched and getting aesthetically pleasant result with a stable function.
