The shape of the chamfer or shoulder depends on the type of ceramic selected and on the technique of cementation. The procedure is presented step by step, as it is performed in a clinical setting, burs used are described.

Standard postoperative clinical and radiographic examinations were performed after surgery and three times in the first year. Spontaneous bone regeneration occurred in all patients. Increased patient age had a negative influence on healing. The shape of the bone defects was more important for healing than their volume. Spontaneous bone healing occurred even in large bone defects in the mandible, therefore this simple treatment with low economic and biological costs should be the treatment of choice, taking into account the patient's age, surgical principles and time of rehabilitation.
