Conditions

Partial-edentulism

Brief summary

The main aim of this clinical trial is to analyze the survival rate of short-length implants (\<4.5 mm) in partial edentulism subjects. 6.5 mm length implants will be used as control arm. Additionally, others clinical parameters (marginal bone loss and prosthetic associated complications) will be measured.

Interventions

Placement of dental implants of 5.5 vs \>6.5 mm length
