Customized anterior guidance for occlusal devices: Classification and rationale

Abstract: Occlusal devices can protect the dentition from attrition and are commonly prescribed for the treatment of myogen-ous orofacial pain. The occlusal scheme of the device controls the forces on teeth during mandibular closure and excursions. Smooth anterior guidance from anterior teeth contact and posterior teeth disclusion has been described as a component of a therapeutic occlusion. Clinical research on the effects of occlusal devices is extensive, but documentation about the actual occlusion studied is lacking. A classification of anterior guidance design for occlusal devices and the rationale for optimum force distribution is presented. This classification can guide clinicians as to the criteria for proper occlusal device fabrication and improve dental research.

Enhancing stability: a review of various occlusal schemes in complete denture prosthesis

Abstract: A practical approach to rehabilitate the edentulous patients to optimal occlusion is not an easy task. Complete denture prosthesis when compared to natural teeth have relatively unstable bases and have no proprioception comparable to the periodontal ligament of the natural tooth and acts as the single unit instead of an individual tooth. To enhance the stability of the complete dentures, the philosophy of the balanced occlusion has been proposed. Balanced occlusion in dentures implies occlusal contacts that contribute to equilibrium of the denture bases on their respective ridges. The search for the ideal occlusal scheme, one which provides stability, comfort, function and esthetics is still underway. While there is little research to support one occlusal scheme over the other, it is known that the prosthesis is less efficient than natural teeth and the ability to chew with it varies with the individual, regardless of the occlusal schemes. Poor oral awareness makes it more difficult for a patient to adapt to the function with the prosthesis especially one with a complicated occlusal scheme. This article reviews several occlusal schemes, their characteristics, recommendations for usage along with their advantages and disadvantages.

Occlusal principles and considerations for the osseointegrated prosthesis

Abstract: The utilization of oral implantology in the field of dentistry is growing at a rapid rate. Although the surgical aspect of the field has expanded into many high-profile areas (i.e., immediate implant placement, distraction Osteogenesis, and the orthodontic anchorage implant), it is the prosthetic aspect that is the most critical for long term success. More specifically, the occlusal considerations for implant supported prostheses make a major contribution to ensure predictable results. This article reviews occlusal principles and clinical applications for long term success of endosseous implants. Keywords - Occlusion, Implant protective occlusion, occlusal scheme, biomechanics, occlusal stability.

Occlusion in implant prosthodontics

Abstract: Implant prosthodontics is a vast and varied field. The most crucial stage in the replacement of a missing tooth using an implant supported prosthesis is the occlusal loading of the fixture. The longevity and the success of the restoration are primarily determined by the direction and amount forces in occlusion. The quality of bone, type of implant, type of prosthesis and patient factors all play important roles in the selection of an occlusal scheme. Each patient must be treated with an individualistic approach. The guidelines for the choice of restoration or type of occlusal scheme must be customized to allow for longevity of the restoration in harmony with the health of the surrounding dentoalveolar structures. This review article encapsulates the different factors to be considered while planning implant restorations and establishing occlusal and prosthetic schemes to protect and preserve the associated oral structures.

Relationship of Occlusal Schemes with the Occurrence of Temporomandibular Disorders

Abstract: Masticatory system is a complex functional unit of the body responsible for mastication, speech, and deglutition process. Temporomandibular disorders (TMD) is used to describe all functional disturbances of the masticatory system. The etiology of TMD is multifactorial, such as occlusal disharmony and emotional stress. The relationship between occlusion and TMD has been highly debated in dentistry, one of the occlusal factors is the occlusal scheme. Occlusal schemes are defined as bilateral canine guidance, unilateral canine guidance, group function and balanced occlusion. However, studies about the relationship of occlusal schemes and the occurrence of the TMD are still limited and remained controversial. Objective: To investigate the relationship of occlusal schemes witht he occurrence of TMD. Methods: A cross-sectional study was conducted at the Faculty of Dentistry, Uniiversitas Indonesia. A total of 127 students were included in this study. Subjects were examined based on Clinical Helkimo Index and divided into TMD and non-TMD groups. Subjects were categorized as non-TMD groups if the value of the clinical Helkimo index was 0 and as TMD group when the value ranged between 1-25. Results: Balanced occlusion schemes has a greater risk of TMD occurrence with odds ratio value 5.6 and 95% confidence interval 1.188 to 26.331 (p=0.021). Conclusion: Balanced occlusion has a significant relationship with the occurrence of TMD.

Lingualized occlusion- a surrogate to success

Abstract: A suitable occlusal scheme would be a critical factor for a successful complete denture. However, there is no conclusive evidence to support which occlusal design is more appropriate for fabricating a successful complete denture. In occlusal design of conventional complete denture, lingualized occlusion can provide better clinical outcomes than other occlusal designs.
