ABSTRACT


Purpose: Estimate The Deviation Between The Planned And The Actual Implant Inserted Using A Mucosa-supported Stereolithographic Surgical Guide In Different Edentulous Arches And Determine The Effect Of The Arch (mandible Or Maxilla) On Accuracy.

Materials and Methods: 16 Implants Were Placed In Completely Edentulous Arches And Divided Into Two Groups. Group (A): Eight Implants Were Placed In Four Patients In The Mandible Using Completely Limiting Mucosa-supported Stereolithographic (SLA) Surgical Guide During Implant Insertion. Two Implants Were Placed In Each Patient Intraforamina. Group (B): Eight Implants Were Placed In Two Patients In The Maxilla Using Completely Limiting Mucosa-supported Stereolithographic (SLA) Surgical Guide During Implant Insertion. Four Implants Were Placed In Each Patient In The Anterior Maxilla. Then The Deviation Between The Planned And The Actual Implant Positions Was Calculated.

Results: For The Maxilla, The Mean Angular Deviation 3.2mm With Standard Deviation ?0.384, The Mean Coronal Deviation 1.88mm With Standard Deviation ?0.37 And The Mean Apical Deviation 1.712 With Standard Deviation ?0.24. For The Mandible, The Mean Angular Deviation 3.197mm With Standard Deviation ?0.578, The Mean Coronal Deviation 1.56mm With Standard Deviation ?0.38 And The Mean Apical Deviation 1.509 With Standard Deviation ?0.173. Conclusion: Insignificant Difference In The Deviation Between The Planned And The Actual Implant Positions Between The Mandible And The Maxilla Placed By Stereolithographic Surgical Guide.
