A comprehensive treatment approach for idiopathic condylar resorption and anterior open bite with 3D virtual surgical planning and self-ligated customized lingual appliance.

Introduction: We report the successful treatment of a 38-year-old woman with bilateral idiopathic condylar resorption and anterior open bite. She had incompetent lips, a gummy smile, increased lower facial height, high mandibular plane angle, skeletal and dental Class II malocclusion with mild mandibular crowding, increased overjet, and mandibular midline deviation to the right.

Methods: The treatment plan included: (1) presurgical alignment and leveling of the teeth in both arches; (2) jaw motion tracking (JMT) to detect mandibular movement; (3) 3-piece maxillary osteotomies with mandibular reconstruction and bilateral coronoidectomies; and (4) postsurgical correction of the malocclusion.

Managing Bone Grafts for the Mandible.

Bone grafting has become an integral part of implant dentistry. To achieve a predictable long-term outcome for osseointegrated implants, a sufficient volume and quality of alveolar bone must be present at implant recipient sites. Resorption of the alveolar ridge and postsurgical or post-traumatic defects of the residual alveolar bone can prevent ideal placement of a dental implant.

Surgical navigation in reconstruction.

Navigational systems are paramount in solving today's traffic dilemmas, and have important applications in the human body. Current imaging must be diagnostic and is often dictated by the radiologist, but it is up to the surgeon to consider surgical procedures and to decide in which case surgical navigation (SN) has advantages. Knowledge of the surgical capabilities of SN is indispensable.

Reconstruction of acquired temporomandibular joint defects.

Various conditions are responsible for the development of acquired temporomandibular joint (TMJ) defects, the reconstruction of which represents a unique challenge, as the TMJ plays an important role in the functioning of the jaw including mastication, deglutition, and phonation. Autogenous reconstructions such as costochondral or sternoclavicular joint graft continue to be the best option in children, owing to their ability to transfer a growth center. In adults, alloplastic reconstructions are a safe and predictable option.
