CBCT evaluation of palatal alveolar protuberance in maxillary molars

Abstract

In recent years, the treatment goal of periodontal disease has developed from the single emphasis on the control of inflammation and improvement of function to the further shaping of oral"Whitening aesthetics", soft tissue transplantation is an important part of periodontal plastic and implant surgery. Periodontal ligament and gingival surgery based on autologous tissue transplantation has predictability and long-term stability, it has also been widely used in aesthetic prosthodontics of the oral cavity. However, the site of soft tissue defect and the donor site of the palate are different in clinical practice, which leads to the change of the operative procedure. Some patients have bony protrusions on the palatal alveolar ridge of their maxillary molars, which may affect periodontal surgery in these patients. CBCT has become a commonly used examination method in various oral clinical disciplines. It can be used to observe the skull from all angles and has a high clinical acceptance. In this article, we reviewed the research progress of CBCT in palatal measurement of maxillary molars and the feasibility of CBCT in evaluating palatal alveolar protuberance of maxillary molars.
