the Effect of Hyaluronic Acid on a Prefabricated CAD-CAM Bone Blocks for Ridge Augmentation

Not Applicable
Completed
Conditions
Atrophy of Edentulous Alveolar Ridge
Interventions
Procedure: prefabricated CAD-CAM allogeneic bone block hydrated using hyaluronic acid
Procedure: prefabricated CAD-CAM allogeneic bone block sterilized hydrated using saline solution
Registration Number
NCT06395818
Lead Sponsor
Tanta University
Brief Summary

Each patient will receive 2 prefabricated CAD-CAM allogeneic bone blocks sterilized with gamma rays with different rehydration methods.

Side I: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using hyaluronic acid \* Side II: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using saline solution Both blocks are fixed with osteosynthesis screws, covered with non resorbable membranes\*\* The membranes will be removed after 6 months, dental implants will be placed and core biopsy will be collected from the site of the implant placement for histologic evaluation

Detailed Description

10 patients will be included in this study with bilateral atrophic posterior mandible for split mouth research

. group I: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using hyaluronic acid group II: prefabricated CAD-CAM allogeneic bone block sterilized with gamma rays hydrated using saline solution under LA mucoperiosteal flap will be elevated to expose the atrophic ridge then the prefabricated CAD-CAM allogenic block either mixed with hyaluronic acid (group I) or saline (group II) will be fixed in its position with titanium miniscrews , The block was coated with a nonporous d-PTFE membrane then closure of flap with nylon second stage: 6 months later exposure of alveolar ridge core biopsy was taken for histological study then insertion of titanium implants.

the aim of the study is to investigate the effect of hyaluronic acid on a prefabricated CAD- CAM bone blocks for ridge augmentation radiographically and histologically.

Primary Outcome Measures
NameTimeMethod
measurement the width and the height of the alveolar ridge6 months

using CBCT the width and the height will be measured with measuring tools in milimeter (mm)

the amount of new bone formation6 months

core biopsy will be underwent histomorphometric analysis to determine the percentage of new bone formation (%)

Secondary Outcome Measures
NameTimeMethod
the sucess of dental implants12 months

usingCBCT to determine the amount of marginal bone loss in (mm)
