Alloplastic reconstruction of the temporomandibular joint.

The Proplast TMJ condylar implant, the glenoid fossa implant, and the TMJ interpositional implants should be singled out as having provided a new and more predictable mode of TMJ reconstruction. The use of these implants in cases of ankylosis, degenerative joint disease, orthognathic deformities, and traumatic injuries has greatly contributed to the success of these reconstructions. These implants represent the state of the art in TMJ reconstruction and increasing data from longer-term follow-up have shown a rate of success much higher than any previous implant used in the TMJ. TMJ reconstruction requires careful surgical planning, meticulous surgical technique, and intelligent perioperative care. Postoperative physical therapy is considered essential in the management of these patients. Complications related to reankylosis have been virtually eliminated, as no postoperative immobilization is required in most cases. Long-term stability of these implants, due to the ingrowth of tissue into Proplast, appears to be assured. Continued experience with the implants and close follow-up of reconstruction patients is necessary in the future to adequately assess the performance of the newer glenoid fossa and TMJ interpositional implants. Certainly, a new era in TMJ reconstruction has begun, resulting in increased benefits to the patients whom we all serve.

The presentation and complications of odontogenic septic shock. Report of a case.

Although most odontogenic infections spread locally to adjacent fascial spaces, usually contiguous with the offending odontogenic pathosis, occasionally such an infection can spread rapidly across the midline and appear on the opposite side of the face and neck. Debilitated chronic alcohol abusers who are nutritionally deficient are more likely to develop serious life-threatening infections, either through serious airway involvement as seen in Ludwig's angina or manifest as a gram-negative septicemia with life-threatening shock and even cardiac arrest, than the usual dental patient with cellulitis. Early recognition through a high index of suspicion and vigorous monitoring will pick up the initial manifestation of toxic shock, as noted in this case report.

Facial bone fractures in children.

From the aforementioned study, the following conclusions can be stated: (1) Patients ranged from 2 to 15 years of age, with no one age group being more susceptible to facial fractures. This fact is contrary to previous findings. (2) No true orbital blow-out fractures were found in patients less thn 7 years of age, primarily because of the lack of maxillary sinus development in that age group. The most rapid development of the maxillary sinus occurs between the ages of 7 to 15 years. (3) In patients from 2 to 7 years of age, fractures occurred at an even ratio of boys and girls. From 8 to 15 years of age there was a boy: girl ratio of about 4.5:1. Of the sixty-seven total patients in the study, boys outnumbered girls by a ratio fo 2.4:1. In order, the condyle, orbit, and mandible were the most common fracture sites observed in the study. This fact is in agreement with past studies. There was no predominant site for any age group or sex. While falls were singly responsible for the greatest number of facial fractures, automobile-related trauma accounted for 47.7 percent of facial fractures in children. In the majority of cases multiple mandibular fractures were of the bilateral condylar type. Hospitalization of patients with automobile-related fractures was approximately 3 days longer than that of patients whose fractures occurred from other causes. More than two thirds of the patients in the study had associated trauma-related medical and dental injuries.

Mandibular staple bone plate implant and prosthesis. Report of a case.

A case treated by the mandibular staple implant fastener system and prosthesis is presented. The phases of therapy, involving preprosthetic surgical preparation, construction of conventional dentures, implantation of the orthopedic appliance, preparation of an interim postsurgical prosthesis, and construction of the definitive prosthesis, are described and illustrated.

Introduction of the sagittal symphysotomy in the treatment of chin deformities.

The management of chin problems occasionally presents a surgical problem to the clinician because of certain anatomic and clinical considerations. This article reviews and discusses some of the conventional surgical procedures in treating chin deformities. The new and versatile sagittal symphysotomy is introduced and described. Three case reports are presented.

Postoperative sequelae after anterior segmental osteotomies.

Reported are the results of a clinical study evaluating the postoperative sequelae of maxillary and mandibular segmental osteotomies. Sixteen patients were evaluated for postoperative pulp vitality, tissue viability, neuropathies, segment stability, and patient response. The findings support the use of this modality when accurate diagnosis and treatment planning are followed by competent surgical procedures.

The role of the dental specialist in the hospital.

As can be seen from this incomplete list of dental specialties and functions they perform in the hospital, there is an increasing participation of dental specialists in the delivery of total health care to the hospitalized patient. In order to disseminate knowledge further of the special protocols of hospital practice and of special hospital dentistry problems, the American Association of Hospital Dentists was formed and publishes a journal containing this special information.
