I have treatment planned a patient for an implant in 46 edentulous site [mandibular first molar]. The coronal surface of the alveolar ridge there has a parabolic morphology. I was planning on flattening the lips of the curve to create a flat alveolar ridge for implant placement. I have adequate bone volume to do this. In this case is there an alternative treatment? Also, would you recommend a bone level or tissue level implant?
