简要总结
The study looks to compare the success rate of lower jaw anesthesia injection (inferior alveolar nerve) that is guided by pre-treatment 3D dental scan (CBCT) versus standard injection technique.
详细描述
A total of 200 participants will be recruited that have existing 3D dental scans (CBCT) and require an implant placement (that will be placed in a two stage procedure) in the lower jaw for which a lower jaw anesthesia injection (inferior alveolar nerve) block will be used. The participants will be randomly assigned into one of two groups. The first group will receive the injection technique that is guided by pre-treatment measurements made from the 3D dental scan (CBCT) during implant placement surgery and if implant is placed as a two-stage procedure, during the second stage implant uncovery will receive the standard injection technique. The second group will receive the standard injection technique first at the implant placement surgery and if implant is placed as a two-stage procedure, during the second stage implant uncovery will receive the injection technique guided by the 3D dental scan (CBCT). If the implant is placed as a one-stage procedure, the second visit will not apply. Following this, subjective and objective measurements on the success of the anesthesia will be measured.
