INTERVENTIONAL
Conditions
Summary
the purpose of this study is to compare the efficiency of non-resorbable membrane versus resorbable membrane in guided bone regeneration in atrophic posterior mandible.
Eligibility
Inclusion Criteria5

- Continuing participation over at least 1 year of follow-up.
Exclusion Criteria6
- Heavy smokers (i.e., 2 or more packs of cigarettes per day);
- Insufficient oral hygiene
- Acute local or systemic infection
- Patients with any systemic disease that may affect bone healing;
- Pregnancy or the possibility of becoming pregnant during the study; and
- Addiction to drugs or alcohol

Interventions
A resorbable pericardium membrane will be fixed with titanium pins on the lingual bone plate (2-3mm from the bone crest) and on the buccal bone plate allowing for packing of particulate mix of bone graft (50% Xenograft: 50% Autogenous graft). Overfilling of the graft will be respected to compensate for future resorption. The membrane will be stretched over the graft ensuring maximum immobilization of the graft.
A non-resorbable polytetrafluoroethylene (PTFE) membrane will be fixed with titanium tacks on the lingual bone plate (2-3mm from the bone crest) and on the buccal bone plate allowing for packing of particulate mix of bone graft (50% Xenograft: 50% Autogenous graft). Overfilling of the graft will be respected to compensate for future resorption.
