Inferior Alveolar Nerve, Mandibular Nerve Blocks

Brief summary

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.

Detailed description

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.

Interventions

2% Lidocaine with 1:100,000 epinephrine will be used for administering the lower jaw anesthesia (inferior alveolar nerve block).

Masking description

The participants will be masked to which technique they are receiving.

Intervention model description

Parallel model for either CBCT guided or intra-oral technique. If the patients receive a two-stage implant placement technique then a cross-over model will be used.

Inclusion criteria

* Male and female patients from the age 18 to 70 years old that are assigned to the 3 clinicians of the graduating class of LSUHSC School of Dentistry Post-graduate Periodontics program. * Patients have been reported as an ASA I or ASA II patient that has never had an allergic reaction to lidocaine based on previous dental experience. * The patient must be missing one or more mandibular teeth and is treatment planned for a mandibular implant that is placed that requires an inferior alveolar nerve block during surgery. * Patient must have an existing CBCT scan within the last year or is planned for a CBCT scan for the purpose of dental implant treatment.
