Resumen
Los terceros molares son los últimos dientes en erupcionar en una edad promedio de 18 a 25 años, pero que con mayor frecuencia no finaliza su dicho proceso normal, y por ende son los más común en observarlos retenidos, es decir que no han perforado el hueso ni la mucosa y no han adquirido su posición normal en la arcada dentaria, por eso el objetivo de este trabajo es analizar radiográficamente los terceros mandibulares retenidos.
Muchas causas de la diferentes posición que puede presentar el tercer molar mandibular son: embriológicas, prenatal, posnatales y locales.
Existen dos formas de retención de los terceros molares, la una es intraosea y la otra subgingival, y de ahí las diferentes posiciones que pueden presentarse.
Para este trabajo se utilizo la investigación bibliográfica, lo que permitió conocer las relaciones anatómicas de los terceros molares mandibulares y también como instrumento utilizo las historias clínicas, radiografías intraorales y extraorales,
Como resultado de este trabajo monográfico se conoció la importancia de un correcto diagnostico de las radiografías periapicales, oclusales y panorámicas preoperatorias para así evitar iatrogenias y por ende aplicar la técnicas quirúrgica adecuado para la cirugía del tercer molar.
The third molars are the last teeth to erupt in an average age of 18-25 years, but more often does not finish its said normal process, and thus are the most common in observing retained , ie they have not drilled the bone and mucous and have not acquired its normal position in the dental arch , so the aim of this paper is to analyze radiographically retained mandibular third . Many causes of different position may file the third mandibular molar are embryological , prenatal , postnatal and local . There are two ways of retaining third molars , one is intraosseous and other subgingival , hence the different positions that may arise. For this work, the literature search was used , which allowed to know the anatomical relationships of the mandibular third molars as well as instrument use medical records , intraoral and extraoral , As a result of this monograph the importance of a correct diagnosis of periapical , occlusal and panoramic preoperative was known to avoid iatrogenic and therefore apply the appropriate techniques for surgical third molar surgery.
