Effects of Three Different Surgical Techniques for Horizontal Ridge Bone Augmentation: A Superiority Randomized Clinical Trial
British University In Egypt
63 participants
Nov 1, 2024
INTERVENTIONAL
Conditions
Summary
the goal of this clinical trial in to investigate the efficacy of three different horizontal augmentation techniques with regards to the volume of bone gained, the quality of the bone gained and the level of patient pain scale. Researchers will compare the volume of bone gained radiographically and the quality of the bone gain using histological analysis. the participants in this study will be required to record and submit a pain scale chart.
Eligibility
Inclusion Criteria1
- Have two or more missing teeth in the posterior mandibular segment; 2) The alveolar ridge in the edentulous site of the selected patients will have a buccolingual width of less than 4mm; 3) Sufficient vertical bone height; 4) Free of any local or systemic condition that may contraindicate ridge expansion procedure
Exclusion Criteria1
- : 1) Patients taking any medication that may interfere with bone healing or bone biology; 2) Patients with any systemic disease that may affect bone healing; 3) Any patients with any previous bone grafting procedure at the site of interest; 4) Smokers; 5) Patient's that have been diagnosed with periodontal disease, as sufficient ridge height would be improbable.

Interventions
Bone blocks will be harvested from the retromolar area after measuring of the size required and measuring of the donor site anatomy. Piezoelectric device will be used to perform the graft osteotomy. The osteotomy lines will be connected and the graft will be mobilized using a bibeveled chisel and mallet. Sharp bony edges will be smoothened and the donor defect was packed with gelatin sponges. The bone block margins will be smoothened and separated into two thinner bone shells using titanium disk with copious saline irrigation. The blocks will be fixed into the recipient site buccally using at least two microscrews leaving a gap to be filled with bone graft. Particulate xenogenic bone graft will be mixed with the autogenous bone chips (50% Xenograft: 50% Autogenous graft) to fill the gap.
: 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 (Permamem membrane, Botiss Biomaterials, Germany) 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.
