This paper presents our new methodology and evaluates the feasibility of buccally tilted and placed implant combined with standard abutment placement in patients with insufficient bone height through implant software programme. Forty patients with 62 mandibular sites were measured in computed tomography (CT) imaging. The Buccally tilted and placed implants combined with standard abutment simulation were administered in implant software programme. The different parameters were measured in CT The localization of inferior alveolar nerve and implant, inclination degree of implant, transversal and vertical thickness of local distances etc. were evaluated in order to eliminate the nerve injury with providing interocclusal relationship. The buccal distance at the mandibular canal level was higher than the lingual distance in posterior mandible at lower first molar region. The mean inclination degree of the implant fixtures were 17.85 +/- 8.01. The mean measurement of the acquired length of implant during implant placement simulation was 11.06 +/- 1.73. The mean distance of the vertical gain was 3.81 +/- 1.84. The hypothesis of buccally positioned and tilted implant placement instead of advanced surgical procedures would be preferable in atrophic posterior mandibula.
