Evaluation of the Cadiax Compact® II Accuracy in Recording Preadjusted Condylar Inclinations on Fully Adjustable Articulator

ABSTRACT Background Mandibular movement analysis is a critical step in making the functional occlusal morphology and improving the diagnosis and treatment of temporomandibular joint disorders (TMDs). Cadiax Compact® is an electronic condylograph that claims to record the horizontal condylar inclination (HCI), Bennett angle (BA) and relative shape of the articular eminence. This study aims at assessing the accuracy of Cadiax Compact® II in its claimed abilities. Materials and methods The electronic condylograph (Cadiax Compact®II) was fitted on the fully adjustable articulator (gamma dental reference- SL). After setting of HCI and BA on the arbitrary degrees, eccentric movements were produced manually on the articulator. The Cadiax recorded these preadjusted angles and the accuracy of its recordings was assessed by comparison of the results with the preadjusted HCI, BA and color inserts as references. Results The majority of the comparisons showed statistically significant differences between articulator settings and Cadiax recordings. However, the maximum difference was about 2.5° which seems acceptable for clinical practice. Conclusion The obtained results showed that Cadiax Compact is an accurate and reliable instrument for diagnostic purposes, yielding reproducible measurements. Despite this, Cadiax is a technically sensitive device that can preclude its routine usage. How to cite this article Ahangari AH, Torabi K, Pour SR, Ghodsi S.

Bone Changes

Temporomandibular joint (TMJ) is one of the most important, unique and structurally has the highest complex synovial system in the body (1, 2). TMJ, encompassing the temporal bone, mandibular condyle and articular disc, is a diarthrodial joint. As a collective form, Temporomandibular Joint Disorders (TMD) is often with multifactorial etiologies, and these diseases can more commonly affect the soft-tissue components of the TMJ including the articular disc and posterior attachment, the osseous components of the TMJ and also the related muscles (3, 4). The most common cause of the regional orofacial pain of non-dental origin is a result of TMD. Additional symptoms may include TMJ sounds such as clicking, pumping, limited or asymmetric mandibular movement (5). As TMJ is covered by a layer of fibrocartilage, unlike other joints in the human body, the mandibular condyles can be damaged due to cartilage degeneration. In addition, arthritis can also be initiated because of the particular dynamics in the maxillofacial area (6). TMD's are frequently associated with degenerative bone changes which can involve the bone structures of the TMJ such as erosion, flattening, osteophytes, subchondral bone sclerosis and pseudocysts (7). To correctly diagnose the dysfunctions associated with the disease and for adequate treatment planning Knowledge about these bone changes is fundamental (8).

Therapy Strategies

Temporomandibular joint disorders (TMD) are a common health condition caused by the structural or functional disorders of masticatory muscles and the temporomandibular joint (TMJ). Abnormal mandibular movement in TMD patients may cause pain, chronic inflammation, and other discomfort, which could be relieved by a variety of drugs through various delivery systems. In this study, we summarized commonly used therapeutic agents in the management of TMD as well as novel bioactive molecules in preclinical stage and clinical trials. The emerging therapy strategies such as novel intra-TMJ delivery systems and implants based on tissue engineering are also discussed. This comprehensive review will strengthen our understanding of pharmacological approaches for TMD therapy.

Key Words Pain

BACKGROUND Temporomandibular joint disorders (TMD) are a group of disorders associated with temporomandibular joints, their associated muscles, and other related structures. TMD present with pain in the joints and related structures which can radiate to the neighbouring areas mimicking ear pains, headaches, neuropathic pain and odontogenic pain. Even though TMDs are more seen in both genders, the ratio of women reporting with TMD is higher (2:1) than men. Pain, the commonest symptom encountered, is usually chronic in duration and mild to severe in intensity. Various other signs and symptoms described are clicking or popping noise, deviation of the mandible, restricted mouth opening and jaw movements. Multiple factors have been reported as an aetiology, however, there is no definite established aetiology to cause TMD. Approaches to the management of TMDs require thorough history taking, clinical and radiological assessment and proper treatment planning. The signs, symptoms, and prevalence of the diseases are also necessary considerations in the treatment planning of TMDs. Traditional approaches in the management of TMDs involve systemic medications, physical therapies, and surgical interventions. The first line of systemic medications to be advised to relieve pain are analgesics. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, muscle relaxants, barbiturates like benzodiazepine have been frequently administered. In recent times, extraction of impacted or buccoverted third molar teeth has also proven to be effective in reducing the pain associated with TMDs. The purpose of this study is to provide new clinical practice guidelines to establish a multidisciplinary approach in the management of patients with TMDs and to improve the patient’s quality of life (QoL).

Removal Technique

ResumoA luxação da articulação temporomandibular é caracterizada quando o côndilo ultrapassa os movimentos limítrofes da sua excursão normal e se desloca para fora da cavidade glenoide, à frente da eminência articular, permanecendo temporariamente retido. A recorrência dessa patologia caracteriza uma condição recidivante ou crônica. As formas de tratamento para essa desordem estão de acordo com a periodicidade e o tempo de evolução e podem variar desde tratamentos conservadores locais até procedimentos cirúrgicos invasivos. O objetivo do presente trabalho é apresentar o relato de um caso clínico de uma paciente com luxação recidivante da ATM tratada através da técnica de remoção da eminência articular, também chamada de eminectomia. O tratamento deste caso através de eminectomia mostrou-se eficiente e adequado em relação à abertura máxima, recidiva e função articular pós-operatória.Palavras-chave: Articulação temporomandibular, transtornos da articulação temporomandibular, luxações articulares, artroplastia.AbstractTemporomandibular joint dislocation occurs when the condyle exceed the borderline movements of its normal excursion and moves out of the glenoid cavity, remaining temporarily retained in front of the articular eminence. The recurrence of this pathology characterizes a relapsing or chronic condition. The forms of treatment for this disorder are according to the periodicity and time of evolution and may range from local conservative treatments to invasive surgical procedures. The aim of the present paper is to present a case report of a patient with recurrent TMJ dislocation treated by the joint eminence removal technique, also called eminectomy. The proposed treatment in this case proved to be efficient and adequate in relation to the maximum mouth opening, recurrence and postoperative joint function.Key-words: Temporomandibular joint, temporomandibular joint disorders, joint dislocations, arthroplasty.
