Evaluation of Two Mini-Implant Lengths in the Infra-Zygomatic Crest Region

"Prior to mini-inplant insertion the patient will instructed to rinse mouth with chlorhexidine mouthwash, then local anesthesia will be applied.~The clinical implication for miniscrew insertion in the IZ crest of adults is 14 to 16 mm above the maxillary occlusal plane and the maxillary first molar.~The self-drilling screw is directed at 90° to the occlusal plane at this point. After the initial notch in the bone is created after couple of turns to the driver, the bone screw driver direction is changed by 55°-70° toward the tooth, downward, which aid in bypassing the roots of the teeth and directing the screw to the infra-zygomatic area of the maxilla. The bone screw is screwed until only the head of the screw is visible outside the alveolar mucosa.~Follow-up: C.B.C.T will be performed after surgery to verify the implant position relative to the adjacent roots"
