CASE OUTLINE
The lower left posterior tooth has been missing for several years. It will undergo restoration using two C-Tech implants (Model: EL-4307). A subsequent application of oxidized zirconia full crowns is planned for final restoration.
TREATMENT PLAN
For the lower left sixth molar, with a width of the alveolar bone measuring 6.8mm and a height of 10.2mm, the proposed treatment plan involves the implantation of a C-Tech implant (EL-4307). Similarly, for the lower left seventh molar, with a width of the alveolar bone measuring 6.2mm and a height of 9.8mm, the proposed treatment plan also includes the implantation of a C-Tech implant (EL-4307) using conventional techniques.
TREATMENT
1、Perform standard disinfection and drape the area with cloths. Administer local anesthesia to the regions of the lower left teeth 5, 6, and 7.
2、Make incisions along the crest of the alveolar ridges of the lower left teeth 6 and 7. Create an incision inside the groove of the lower left fifth tooth. On the cheek side of the lower left tooth 7, make a distant and central reduced tension vertical oblique incision. Carefully reflect the gingiva to expose and smooth the bone surface.
3、Precisely position the C-Tech implants (Model: EL-4307) in the locations of the lower left teeth 6 and 7. Use pilot drills to reach the working length and gradually prepare the boreholes to 3.9*9mm. Collect autogenous bone for grafting and implant the C-Tech implants (EL-4307) with closure screws. Apply a torque of 60N for the lower left tooth 6, achieving a marginal bone height of M3/D1.5/B1/L1, and apply a torque of 60N for the lower left tooth 7, achieving a marginal bone height of M1.5/D1/B1/L0. Place autogenous bone on the cheek side and neck of the lower left implants 6 and 7. Securely suture and control bleeding.
4、After 5 months, take an impression and replace the restorative abutments with Model: EL-4502F/2. Perform an oxidized zirconia full crown restoration, fixating it with adhesive fixation for permanent restoration.
