Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized clinical trial (RCT) study investigates if there is any difference in absolute vertical bone gain between perforated dense-polytetrafluroethylene (d-PTFE) mesh vs perforated d-PTFE mesh covered with a native collagen membrane.

The primary endpoint is absolute vertical bone gain. The secondary endpoints are regeneration rate, complications rate, and pseudoperiosteum formation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ridge Augmentation with a perforate PTFE mesh

Vertical and horizontal ridge augmentation will be performed using d-PTFE mesh. The graft material is autograft mixed with a xenograft in a 1:1 ratio.

Group Type ACTIVE_COMPARATOR

Guided bone regeneration with a PTFE membrane

Intervention Type PROCEDURE

Xenograft bovine spongious bone substitute mixed with autogenous intraorally harvested particulated bone is used and spatially contained with a PTFE membrane secured with Ti pins and screws.

Group Type EXPERIMENTAL

Guided bone regeneration with a PTFE+collagen membrane

Intervention Type PROCEDURE

Xenograft bovine spongious bone substitute mixed with autogenous intraorally harvested particulated bone is used and spatially contained with a PTFE membrane secured with Ti pins and screws and covered with a Collagen membrane subsequently.
