Effect of axial height and palatal wall on the resistance form of a maxillary anterior metal-ceramic crown preparation.

The effect of palatal wall modifications and height of a maxillary central incisor on the resistance form of metal-ceramic crowns are compared. Dies with adequate preparation height show no crown dislodgement in groups with a palatal wall, palatal wall/groove, and no palatal wall. This study suggests the use of a palatal groove improves the resistance to dislodgement in short maxillary anterior tooth preparations.

Mandibular reconstruction with vascularized fibula flap and osseointegrated implants: a clinical report.

Primary and secondary reconstruction of mandibular discontinuity defects with vascularized flap is currently the standard of care in many institutions. The most commonly used donor site for such flaps is fibula. Fibula provides enough bone length, allows 2-team approach, and has low donor site morbidity and abundant periosteal blood supply.

Linguoaxial wall and cervicoincisal dimension of anterior crown preparation: effect on retention.

This study sought to evaluate the effect of the linguoaxial wall, a lingual auxiliary groove, and the cervicoincisal dimension of the anterior tooth preparation on retention. A simulated maxillary central incisor was prepared following "ideal" guidelines. The linguoaxial wall of these preparations was modified and the samples were divided into three groups: preparations with a linguoaxial wall (Group 1), preparations with a linguoaxial wall and groove (Group 2), and preparations with no linguoaxial wall (Group 3).

"All-on-Four" immediate function concept and clinical report of treatment of an edentulous mandible with a fixed complete denture and milled titanium framework.

The "All-on-Four" concept-tilting the distal implants in the edentulous arches improves the prosthetic support-increases the inter-implant distance and provides better implant anchorage in the bone by using longer implants. Computer milling of a solid block of titanium also provides frameworks with improved fit and fewer technical challenges than conventional cast or noncast approaches. This clinical report describes a method of restoring an edentulous mandible with the "All-on-Four" immediate function concept and a milled titanium framework.

Preservation of the gingival architecture with the scalloped implant design: a clinical report.

Replacing the missing maxillary anterior teeth with dental implants and maintaining the soft tissue structure and alveolar profile is an esthetic challenge for the restorative dentist. This clinical report describes the immediate provisional placement and prosthetic rehabilitation of 2 missing maxillary central incisors with scalloped dental implants.
