Conditions

Mandibular Atrophy

Brief summary

Zirconia can be considered as an alternative and innovative material suitable for GBR because it has high biocompatibility, together with a scarce tissue integration. Zirconia barriers could be a predictable and alternative barrier material for GBR in terms of (i) biocompatibility, (ii) ease of use and removal, (iii) exposure management, (iv) bone regeneration outcomes.

Interventions

OTHERcustomized Zirconia barrier

It includes eight patients seeking for placement of customized Zirconia barrier after GBR in 1st stage surgery then implants placement in 2nd stage surgery in the alveolar ridges.

OTHERprebent titanium mesh

It includes eight patients seeking for placement prebent titanium mesh as barriers after GBR in 1st stage surgery then implants placement in 2nd stage surgery in the alveolar ridges.

Inclusion criteria

* Patients are systemically medically free according to the American Society of Anesthesiologists (ASA) considered as ASA I. * Ability to maintain good oral hygiene as evidenced in recall visits. * patients who had a partial or completely edentulous alveolar ridge with apparent 3D defect following teeth loss. * All patients were free from any local or general disease that may interfere with bone healing and had no history of previous grafting procedure at the designated edentulous ridge. * The ridge had to exhibit severe vertical and horizontal (3D) alveolar ridge deficiency with alveolar ridge height less than 7 mm from the alveolar crest to the inferior alveolar canal and width less than 5 mm which was firstly measured by CBCT, or a clinically apparent increase in inter-arch space relative to the adjacent natural teeth. * Pre-operative clinical assessment of soft tissue coverage was done to cover the graft and its membrane, in addition to assessment of occlusion and inter-arch distance should allow for the graft, membrane, implan and the future prosthesis.

Exclusion criteria

* Smoker (\> 25 cigarettes/ day). * Patients undergoing radiotherapy or chemotherapy * Patients having infection or local lesions in the area of surgery. * Patients with diabetes mellitus or bone diseases which may compromise the results. * Patient with poor oral hygiene or active periodontal disease. * Patient with limited mouth opening. * Participation in other clinical trials

Design outcomes

Primary

MeasureTime frameDescription
change in vertical height of ridgeup to 6 monthsCone Beam Computed Tomography (CBCT) was done immediately (1 week) and after six months to evaluate the changes in vertical, horizontal and volumetric measurements of the ridge. OnDemand3D™ software was used to evaluate vertical and horizontal height. Measurements were taken as follows: From the toolbar, the ruler was selected from the measurement section.
change in horizontal width of ridgeup to 6 monthsCone Beam Computed Tomography (CBCT) will be done immediately (1 week) and after six months OnDemand3D™ software will be used. Measurements were taken as follows: From the toolbar, the ruler was selected from the measurement section.
change in volume of ridgeup to 6 monthsCone Beam Computed Tomography (CBCT) will be done immediately (1 week) and after six months OnDemand3D™ software will be used. Measurements were taken as follows: From the toolbar, the ruler was selected from the measurement section.

Secondary

MeasureTime frameDescription
symptoms of infectionup to one monthAny symptoms of infection including swelling, redness, hotness, pus discharge, and pain will be recorded
manifestations of wound healing disturbanceup to one monthobservation for any manifestations of wound healing disturbance, as wound dehiscence and hardware exposure will be recorded
