Aim: The aim of this study is to evaluate the anesthetic efficacy of mylohyoid and buccal nerve anesthesia at the posterior edentulous mandible performed versus regional anesthetic block to inferior alveolar nerve in dental implant surgery. Materials and Methods: The study was designed in two groups. In the first group A, 14 voluntary adults (7 female and 7 male) received local infiltrations of 1 ml articaine HCl 4% with epinephrine 1/200 000 to ipsilateral mylohyoid and buccal nerves. In the second control group B (9 female and 5 male), the inferior alveolar and the buccal nerve blocks were performed. VAS scales were obtained from patients to determine the level of pain during incision, drilling, implant placement and suturing stages of implant surgery. Results: Combination of buccal and mylohyoid nerve block offered acceptable level of anesthesia. 2 patients from the Group A stopped up the ongoing surgery and had extra regional anesthesia by inferior alveolar nerve block. In Group B, patients were operated successfully.Conclusion: Local anesthetic infiltrations of the mylohyoid and the buccal nerve may be considered as an alternative method of providing convenient anesthetic state of posterior mandibular ridge.
