A Clinical Study Of Simultaneous Implant Placements With Hydroxyapatite And β-tricalcium Phosphate Mixture Collagen Bone Graft Matrix In Maxilary Sinus Floor Elevation

Objective:This study evaluate the simultaneous implant placements with foramic (amixture consisting of bioresorbable purified fibrillar collagen and hydroxiapatite/β-tricalcium phosphate ceramic) in maxilary sinus floor elevation(residual boneheight from3to5mm).Materials and methods:This study subjects involved ten patients(four men and six women) withloss of at least one maxillary molar and possessed a residual bone height fromethree to five millimeters following the maxillary sinus elevation withsimultaneous implant placements and bone augmentation by foramic (a mixtureconsisting of bioresorbable purified fibrillar collagen and hydroxiapatite andβ-tricalcium phosphate ceramic).28MIS implants (8.0-11.5millimeters long and3.75-5.0millimaters in diameter) were installed. Each case following healing periodsix months, and all patients were follow up and observed for one year.Results:In six months follow-up observation after maxillary sinus elevation,maxillary sinus floor bone were enhance at least6mm height with foramic bone graft matrix. Implant were successfully installed and binding to newly formedbone, no occurrence of significant bone resorption or infection with any patients.Conclusion:foramic bone graft matrix used in simultaneous implant placements withmaxilary sinus floor elevation, revealing a significant repair effect and worthy ofrecognition and promotion of clinical use.
