Mixed fixed and removable denture with precision attachments, grooves, drive bars and coulisses

Fig. 1.The upper incisor group from canine to canine was saved with cores (see Patients' Section) inserted in roots which were saved by means of an osteotomy-osteoplastics operation to "pull them out" of the bone and gum since they were fractured or decayed so deeply that they were destroyed even below the level of the bone crest. (see the section SURGICAL OPERATIONS - Complete oral rehabilitation - Surgery of coronal-radicular fractures and complete oral rehabilitation - Flap repositioned apically with fibrin glue in the treatment of a lingual coronal fracture extending below the bone crest (Ingle's class IV) of dental element 4.7 in this site)
