ABSTRACT
The Purpose Of This Study Was To Evaluate The Effect Of Beta- Tricalcium Phosphate On The Osseointegration Of Dental Implants Placed Simultaneously With Maxillary Sinus Lift. Patients & Methods: This Study Was Carried Out On 10 Dental Implants Placed Simultaneously With Maxillary Sinus Lift (4 Males And 6 Females) With Average Age 39.9 Years. The Surgical Procedures Were Performed Under Local Anaesthesia. They Included Edentulous Posterior Maxilla With Extensive Pneumatization Of The Maxillary Sinus, Width Of Edentulous Ridge Not Less Than 6mm While Height Of Alveolar Ridge With Minimum Average Bone 5 - 6mm To Allow Initial Stability Of The Dental Implant. Maxillary Sinus Lift Procedure Was Done By Lateral Technique And Dental Implant Was Inserted Simultaneously. Postoperative Clinical And Radiographic Evaluations Were Done For Each Patient After 4 And 6 Months Postoperatively To Detect Bone Density Around The Implant. Implant Stability Was Measured By Osstell Immediately, 4 And 6 Month Postoperatively.

Results: Radiographic Evaluations Revealed That Bone Density Measurements After 6 Months Were Highly Significant Increased More Than After 4 Months Postoperatively. The Implant Stability Measurements After 6 Months Were Increased More Than That 4 Months Postoperatively And Significantly Increased More Than That Immediately Inserted Implant . Conclusion: Beta Tri-calcium Phosphate Graft Increased The Success Rate Of Implant Osseointegration And Stability Following Maxillary Sinus Lift
