| Summary: | <p style="margin-top: 0cm; margin-right: -7.1pt; margin-bottom: .0001pt; margin-left: 0cm; line-height: normal;"><span style="font-family: verdana; font-size: small;"><strong>Introducción:</strong> Las fracturas coronales complicadas en premolares y molares, que involucran también compromiso radicular ocurren usualmente en dientes plenamente formados y engastados en hueso alveolar ya maduro. Pueden alcanzar cualquier segmento de raíz, resultando las de peor pronóstico aquellas que alcanzan el tercio medio radicular, debido a los altos riesgos de aparición de reabsorciones externas asociadas a las terapias convencionales para tratar las mismas.<br /> <strong>Objetivo:</strong> Describir un caso de restauración de una fractura corono-radicular del tercio medio en un primer premolar superior derecho, utilizando el método abierto, en una sola visita.<br /> <strong>Presentación del caso:</strong> Paciente de 58 años, masculino, con antecedentes de salud, que acude a consulta tras sufrir traumatismo dentoalveolar consistente con fractura complicada de corona y raíz del tercio medio, corroborado clínica y radiográficamente. Requirió cementación de perno, reconstrucción del tercio radicular, conformación de muñón y estabilización para el logro de la restauración integral. Todo se realizó en una sola visita.<br /> <strong>Conclusiones:</strong> La restauración clínico-quirúrgica integral en fractura complicada de corona y raíz del tercio medio es una alternativa factible de realizar en una sola visita, que garantiza una rápida recuperación de las funciones buco-dentales.</span></p><p style="margin-top: 0cm; margin-right: -7.15pt; margin-bottom: .0001pt; margin-left: 0cm; line-height: normal;"><span style="font-family: verdana; font-size: small;"><strong> </strong></span></p><p style="margin-top: 0cm; margin-right: -7.15pt; margin-bottom: .0001pt; margin-left: 0cm; line-height: normal;"><span style="font-family: verdana; font-size: small;"><strong>Palabras clave:</strong> Traumatismo dental, fractura de corona y raíz, endodoncia técnica de perno muñón, restauración dental, cirugía dental.</span></p><!--[if gte mso 9]><xml>
