The aim of the study at issue is to deepen the knowledge of Eagle Syndrome and Ernest Syndrome in order to get the practical and scientific directions providing the doctor with a more effective diagnosis, clearing the relationship between them and the TMJD (temporomandibular joint disorders). It might show the clinical procedure concerning the mentioned diseases. Once the aching syntomatology is similar to the signals and symptoms of the temporomandibular disorders, the differencial diagnosis and medical care of the disease get to be complicated. Etiological facts like stress, physical harm on the head, mandibular injuries, car accidents, dental care, surgeries, intubation, tonsillectomy, bruxism or dental tightness are studied and developed in this present study, which also contributes toward a presentation of a simple and important diagnosis technique resource to the evaluation of the cited abnormalities by analyzing panoramic radiographies. An alteration in the stylohyoid chain was testified in 86 from 1063 panoramic radiographies. They were all examined in detail and the patients were given a medical evaluation enquiry. The results made us conclude that factors like stress, mandibular injuries, head and neck traumas could be the causing factors of the alteration in the stylohyoid chain. Furthermore, an unexpected datum was achieved -100% 1of patients under the study suffered from occlusion disorder, which made us infer that a new etiological factor could be proposed.

Oral rehabilitation with free-end removable partial denture (RPD) is one of the major challenges in prosthodontic dentistry. The absence of a distal abutment produces undesirable RPD movement during masticatory function due to the high resilience of the residual ridge, which limits the denture efficiency and may damage the abutment teeth and bone over time. The advent of dental implants made possible to substitute the missing teeth with fixed implant-supported dentures as the first choice treatment to overcome such inconveniences. However, this indication may not be suitable for all patients due to financial, anatomical or systemic health conditions. Nevertheless it is possible to improve free extension RPD by using implants in the posterior edentulous ridge to achieve biological, biomechanical, physiological and social benefits. This article aims to present a case report on oral rehabilitation in which a RPD was made combined with an implant for posterior support in a sizeable edentulous ridge. The patient appreciated the retention improvement and the aesthetic result. The combination of a RPD with a posterior implant is an alternative treatment for cases in which implant-supported fixed prosthesis is not indicated, reducing the displacement and minimizing the limitations of the free-end devices.
