Characteristic features of orthodontic treatment of tooth retention caused by hyperdontia

Abstract

Supernumerary teeth often cause tooth retention. The presence of supernumerary teeth, depending on their shape, number and location, can create unfavorable conditions for the development of the dental arches and occlusion, resulting in significant functional and esthetic disorders.The article presents clinical cases of patients with hyperdontia and tooth retention. Each case involves a thorough patient examination and an individual approach to the choice of treatment. The authors' experience in treating retention caused by hyperdontia allowed a range of treatment methods to be used, depending on the functional state of occlusion, the patient's age and the characteristics and location of the impacted and supernumerary teeth. In two patients with dentition in the early transitional period, the central incisors erupted without a doctor's intervention within three months after the extraction of supernumerary teeth. In both cases, the subsequent orthodontic treatment aimed at correcting the torsiversion the incisors displayed upon eruption. Another case demonstrates a method of treatment that provides minimal loss of bone tissue: the supernumerary tooth were initially shifted to the alveolar bone surface and then removed. The last case describes a complete surgical-orthodontic treatment. Bone grafting was performed after the extraction of a supernumerary tooth, and an impacted tooth was moved to the newly created bone tissue. All these methods of treatment have their specific indications and can be implemented after a thorough examination of the patient.

Erupción forzada de incisivos centrales superiores permanentes retenidos como consecuencia de dientes supernumerarios. Reporte de caso.

“…La extracción quirúrgica de dientes retenidos requiere de gran precisión en el diagnóstico y localización, el uso imágenes en 3D, tomografía computarizada de haz cónico (CBCT) proporcionan mayor potencial que la radiografía convencional para obtener información detallada y precisa, que disminuya la posibilidad de errores quirúrgicos. 9 Se ha sugerido que hasta el 75% de los pacientes con dientes retenidos luego de la extracción de los dientes supernumerarios se genera una erupción espontánea, cuando este proceso no ocurre, la exposición quirúrgica es indicada. 10…”

Diagnóstico clínico e prevalência de mesiodens na infância: revisão de literatura / Clinical diagnosis and prevalence of mesiodens in childhood: literature review

“…Em relação ao momento mais oportuno para a exodontia do supranumerário, é importante frisar que não é bem definido na literatura (MAKEYEV et al, 2017;ROSA et al, 2019).…”

“…De acordo comMakeyev et al (2017) em casos em que o mesiodens esteja retardando a erupção dos dentes incisivos e esteja localizado em um local favorável, a exodontia pode ser efetiva para erupção espontânea. Mas se ainda assim não houver esfoliação, o CD deverá encaminhar ao ortodontista para dar início ao acompanhamento ortodôntico.…”
