ABSTRACT
Objective: The Objective Of This Study Is To Assess, Clinically & Radiographically The Effectiveness Of Utilizing BondBone In Impacted Mandibular Third Molar Sockets As Socket Preservative. Patients And Methods: Sixteen Patients Were Selected From The Outpatient Clinic Of Oral And Maxillofacial Surgery Department, Faculty Of Oral And Dental Medicine, Cairo University. Adult Healthy Patients Suffering From Impacted Mandibular Third Molar Teeth Were Chosen For This Research. Subjects Were Between 19 And 45 Years Of Age.6 Males Patients And 10 Females Patients Participated In This Study. 16 Patients Were Divided Equally Into Two Groups; Study Group: Eight Teeth Sockets Of Impacted Mandibular Third Molar Teeth Were Immediately Preserved By BondBone Mixed With Xenogenic Cancellous-cortical Bone Graft. Control Group: Eight Teeth Sockets Of Impacted Mandibular Third Molar Teeth Were Left Without Grafting; Just The Blood Clot Was Left In The Socket To Heal Spontaneously.

Results: The Present Study Reveals That The Study Group; There Was No Statistically Significant Change In Mean Bone Density After 4 Months. While For The Control Group; There Was A Statistically Significant Increase In Mean Bone Density After 4 Months. Conclusion: Using BondBone After Extraction Of Deeply Impacted Mandibular Third Molar Decreases The Post-operative Complications Such As Fracture At The Angle Of The Mandible And Periodontal Defect Distal To The Lower Second Molar.
