Table 1 Comparison between "conventional extraction of complicated roots "and "Expandable Micro-motor Bur technique"
Criteria | Conventional complicated root-extraction | Expandable Micro-motor Bur |
|---|---|---|
Invasion to surrounding anatomical structures (maxillary sinus exposure, nerve injury and innervations disorders) | More probable | Less probable |
Need for mucoperiosteal flap and/or osteotomy of buccal bone | More probable | No or with less extension |
Surgical approach | More invasive | More conservative |
Operative and post-operative complications | More probable | Less probable |
Operation duration | Longer | Shorter |
Stress of practitioner and patient | More | Less |
Success of immediate implant placement | Less probable | More probable |
