Los implantes dentales han evolucionado de forma sustancial en los 迆ltimos 40 a os; sin embargo, dudas sobre las caracter赤sticas de la reparaci車n 車sea contin迆an toda vez que nuevos dise os y nuevos m谷todos quir迆rgicos son aplicados. El objetivo de esta investigaci車n es evidenciar la presencia de tejido mineralizado en diferentes regiones del implante. Se elabor車 un estudio basado en un modelo de restauraci車n inmediata, aplicado en la mand赤bula de 7 canes machos. Se realizaron las exodontias de los premolares mandibulares y, despu谷s de 3 meses de recuperaci車n, se instalaron 2 implantes end車seos bilaterales, siendo uno de tipo c車nico y otro de tipo cilindrico. Despu谷s de dos periodos de sacrificio se realizo una evaluaci車n histomorfom谷trica en los cortes seleccionados. Los resultados se presentan de forma porcentual estableciendo comparaciones entre las 芍reas cervical, media y apical. Los implantes de morfolog赤a c車nica sometidos al modelo de restauraci車n inmediata, presentaron mayor formaci車n 車sea en todos los niveles evaluados. En todas las condiciones de trabajo el 芍rea cervical present車 mayor presencia de tejido mineralizado que el 芍rea apical. Concluimos que el modelo de restauraci車n inmediata no es un obst芍culo para la instalaci車n de la secuencia apropiada de reparaci車n 車sea y que diferentes factores deben estar asociados a la mayor formaci車n 車sea presente en el 芍rea cervical de los implantes dentales. Dental implants have evolved of substantial form in the last 40 years; however, doubt about osseous repair characteristic are maintained because new design and surgical method are applied. The aim of this research is show the mineralized tissue in different areas of the implant. Was done a study based to a immediate load model applied in 7 male dogs mandible. Was realized the dental extractions of de bilateral mandibles bicusp and after to 3 month of recuperations was installed two bilaterally implants, been conical and cylindered shape. After of two sacrifices period was realized a histomorphometric analysis in the selection cut. The results are present with perceptual form, establishing cervical, meddle and apical comparison. Conical implants with immediaterestoration model were present more osseous formations in all evaluated level. For all conditions of work, cervical area presented more mineralized tissue than apical area. We conclude that immediately restoration model it is not an obstacle for the installation of the appropriate sequence for the osseous reparation and that different factors have been associated to the more osseous formation in th
