Study summary

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

    Device: BTI Implant

  • non-short length implant (≥6.5 mm)

    Device: BTI Implant

Interventions

  • DeviceBTI Implant

    BTI Dental implants are non-active medical device, single use, non resterilizable, biocompatible and sterile devices made of alloplastic materials (Titanium) intended to be surgically implanted into alveolar and/or basal bone of the mandible or maxilla to provide support and a means of retention for a dental prosthesis (e.g. bridge, single-tooth, overdenture).
