Another one. Sorry for long description. Wish you a great day. Bending video link https://youtu.be/Tw7TSK5qtOM (Maneuver Technique with cortical anchorage) A 39 years old female showed up with missing upper right 1st premolars. Tooth was extracted several years ago due to non-restorable deep cavities. Clinical examination and radiographic examinations were performed. The radiographic examination showed expected bone quality of D5 bone, and bone height of 22 mm at the area of tooth 14. Bone width buccolingually was 3.5mm. Clinical examination showed narrow ridge at area of extracted tooth in comparison to neighboring teeth. Patient was informed with procedures needed to place dental implants and installation of restorations to restore missing teeth. Topical anesthesia gel was applied 3 minutes prior to local anesthesia injection. Local anesthesia injection was administered buccally C3514 Trate single piece Compressive implants (Bäch, Switzerland) was chosen for use to replace tooth 14. Implant site preparation was performed according to manufacturer’s instruction, a drill corresponding to the chosen implant size was used at implant site, drilling was performed in a total flapless technique directly into bone through the ginigva, with drilling 2mm more than desires height to compensate the gingival thickness. Drilling was performed with speed of 800 RPM, Torque of 30 Ncm and normal saline irrigation. This was followed by the corresponding compressive screw. Compressive screws was not inserted to the end of screw desired height in order to use implant self-tapping criterion to increase primary stability. Implant was screwed primarily in place using the plastic implant mount until it reached reasonable torque that enabled to remove the plastic mount and the use of the torque wrench with insertion tool to insert the implant in bone. Implant insertion with the torque wrench was continued until the margin of abutment part of the implant was inside gingiva with 1mm; in order to enable the placement of restoration margin subgingivally. Implant site preparation. Insertion torque did not exceed 20 Ncm as shown by the torque wrench. Implant was inserted in offset angel other than that for neighboring teeth, to cope with residual bone, as bone width did not allow correct implant insertion angulation. So, the decision was taken to leave the implant unloaded for 2 month, and also to leave it with offset angulation until suspected osseointegration takes place 2 months later. Occlusal clearance was accomplished with metal cutting stone to remove excess of abutment that can interfere with occlusion, to ensure that implant is not subjected for forces during the suspected healing period. CBCT radiographs were recorded implant. CBCT showed how implant was near for both cortical plates. Patient was instructed for use of (Augmentin 625 mg tab t.d.s.) and Ketolac 10 mg tab bis (KETOROLAC TROMETHAMINE, Surav Chemicals limited, Cairo, Egypt)) for six days. Immediate postoperative periapical radiographs were recorded. Patient was scheduled for final impressions and restorations to be after 2 months of implant insertion. According to schedule, patient was recalled. Implant stability were checked with surgeon hand. Implant bending was accomplished with use of torque wrench and insertion tool, until reached the desired angulation. Addition silicone impressions were taken and sent to lab. Porcelain-fused-to-metal restorations was manufactured, occlusion was checked and it was cemented with use of glass ionomer.
