Background/Aim. Balanced occlusal arrangement of artificial teeth and balanced occlusion is a specific type of occlusion that preserves the stability of complete dentures. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. The aim of this study was to assess the influence of balanced occlusal arrangement of artificial teeth on the decrease in reduction of edentulous alveolar ridge. Methods. A longitudinal study on 91 fully edentulous patients was conducted using their panoramic radiographs and parameters of vertical dimension of edentulous ridges. All the patients were clinically examined by the same and a qualified dental practitioner. Numerical values of parameters of vertical dimensions of edentulous ridges and lines were statistically processed and compared using the Student?s t-test. Results. Vertical dimensions and heights of edentulous ridges were different after comparison of parameters in complete denture wearers with balanced occlusion and complete denture wearers without bilaterally balanced occlusion, as well as between male and female edentulous patients. Statistically significant differences of heights were established in complete denture wearers? with a set of artificial teeth without balanced occlusion, at the baseline and 12 months after wearing of complete dentures. Conclusion. Balanced occlusion is a favored occlusal design in setting of artificial teeth in conventional complete dentures, which preserves edentulous ridge and influence the stability of dentures.

ABSTRACT Purpose The retention of complete dentures is frequently difficult in edentulous patients with a severely resorbed residual alveolar ridge. In such cases, implant overdentures having a stronger retention force are useful. Although there are various types of attachment systems for implant overdentures, they are frequently complicated. We are, therefore, developing a simple attachment system focusing on a soft lining material for the female connector. The purpose of this study was to evaluate the retention force of implant overdentures applying a soft lining material for the attachment. Materials and methods The models in which seven male and female connector pairs were used. As the control, a rubber O-ring attachment system, in which a rubber O-ring female was paired with a metal ball anchor (male), having a diameter of 1.7 or 2.2 mm. In the attachment system with a soft lining material, a female component was made up of soft lining material paired with a male having a diameter of 1.7, 2.2, 2.5, 2.7 or 3.0 mm. In measuring the retention force, the maximum force required to dislodge the male from the female was recorded by a digital force gauge. Results With the rubber O-ring, the retention force was 2.9 ± 0.2 N for the 1.7 mm male and 3.3 ± 0.3 N for the 2.2 mm male; these values were higher than the respective retention forces when using a soft lining material as the female and a male of the same diameter. However, with the female comprising soft lining material, the retention force exceeded 4 N for the 2.5, 2.7 and 3.0 mm males and was higher than the retention forces for the rubber O-ring. Conclusion The proposed attachment system with soft lining material for implant overdentures provides a clinically sufficient retention force when the diameter of the male exceeds 2.5 mm.

ABSTRACT Over denture is favoured treatment modality for an elderly patient with few remaining teeth, because of adaptation to wearing is facilitated. Roots maintained under the denture base preserve the alveolar ridge, provide sensory feedback and improve the stability of the dentures. In comparison with complete dentures, overdentures may provide better functions. The most common problem of mandibular complete denture is retention & stability and alveolar ridge resorption; hence care must be taken to preserve it.

AbstractA 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.

The assessment and reestablishment of the occlusal vertical dimension (OVD) are considered important factors in the treatment of complete denture wearers. The long-time use of a complete denture can result in jaw displacement due to abrasion of the artificial teeth and residual ridge resorption, causing esthetic complications. Most patients with old dentures and incorrect OVD accept reestablishment of the OVD with new complete dentures, even if they were used to their old dentures. The present clinical report describes a method of gradual reestablishment of OVD using a diagnostic acrylic splint on artificial teeth in old complete dentures before the manufacture of new complete dentures.Clinical Significance. The use of a reversible treatment for reestablishment of the OVD in old complete dentures with a diagnostic occlusal acrylic splint allows for the reestablishment of the intermaxillary relationship, providing physiological conditions of masticatory performance associated with the recovery of facial esthetics in edentulous patients.

Introduction. Complete denture reinforced with metal bases is fabricated in cases of fracture risk as well as in selected patients with neuromuscular disorders. The aim of this report was to present different designs of metal framework for complete denture and their advantages in the treatment of edentulous patients. Material and Methods. The study included 116 edentulous patients who received complete dentures. The respondents were divided into two groups according to the type of denture used. Thirty one patients were rehabilitated with complete dentures reinforced with metal base, whereas 85 patients received conventional complete acrylic dentures. Metal bases were fabricated using Co-Cr-Mo alloy. Two designs different in regards to the vibrating line were fabricated: metal frame extended to the vibrating line and acrylic resin extended to the vibrating line. After investing and casting, metal bases were electropolished. Subsequent processes of arranging artificial teeth, waxing, flasking and finishing completed the fabrication process of dentures. Results. Denture base fractures were prevented in majority of patients. The design of upper denture where metal frame was extended to the vibrating line and metal base with elongation over the convex edentulous ridge in lower jaw were the most favored and successful in prosthetic rehabilitation of experimental group of edentulous patients. There was no need for rebasing of complete dentures reinforced with metal base. Conclusion. Complete denture reinforced with metal base presents a favorable design for rehabilitation of edentulous patients with well pronounced edentulous ridges and low tendency to resorption.

The aim of this study was to provide longitudinal evaluation of the changes after complete dentures therapy and the rate of residual ridge resorption through a six-year period of denture wearing. The authors presented the case of a 76-year-old patient, edentulous for twelve years, wearing complete dentures for six years, with the eugnat jaw relationship. Cephalometric radiograph was carried out in the process of new complete denture production, while the evaluation was carried out after six years. Cephalometric analysis was performed by using ?Dr. Ceph? computer software (FYI Technologies, GA, USA). After six years, the reduction of anterior total facial height was 5.5 mm and the anterior lower facial height was 5.5 mm, the vertical residual ridge reduction of the maxilla was 1.4 mm and the reduction of the mandible was 3mm. The study confirms the reliability and advantages of cephalometric analyses and reveals their application possibilities in prosthetic diagnostics and therapy, as well as in evaluation of rehabilitative results in edentulous patients and longitudinal analysis of changes on the orofacial complex tissues and intemaxillary relationships.

Processing Errors

There has been an increase in the incidence of complete edentulism among the elder patients. Complete dentures are the most common and preferred treatment of choice. Complete dentures help in masticatory function and restore the facial shape of the edentulous patients. Fabrication of the complete dentures is, therefore, a very important task for the clinician to ensure patient satisfaction. Errors may occur during the denture fabrication and these are called processing errors. It is a multifactorial process. The aim of the survey is to study the errors that occur during processing of a complete denture. It is a questionnaire based study conducted with a batch of 100 dental students. The questionnaire consisted of 16 questions focused on different fabrication techniques, timing, materials used, etc. by various students. The data collected was represented statistically and discussed. Dough technique was the most preferred method adopted by 39% of the students. Shorter curing cycles produced less defects, but majority of the students used longer cycles (41%). Most of them reported fractures (16%) and microporosities (11%) as defects. We can conclude that there are a few areas of error during the processing of dentures by the dental students. The incidence of these errors, however appears to be low. There is a scope for CAD/CAM complete dentures in the future to eliminate the possibilities of errors.

Edentulous Patients

The mucosa that covers the residual ridges of edentulous patients may present some distortion or displacement when occlusal loading is applied in complete dentures. This distortion and movement of the denture can result in acceleration of residual ridge resorption and loss of retention and stability. The aim of this study was to analyze the pattern of upper complete denture movement related to underlying mucosa displacement. A sample of 10 complete denture wearers was randomly selected, which had acceptable upper and lower dentures and normal volume and resilience of residual ridges. The kinesiographic instrument K6-I Diagnostic System® was used to measure denture movements, according to the method proposed by Maeda et al.7, 1984. Denture movements were measured under the following experimental conditions: (A) 3 maximum voluntary clenching cycles and (B) unilateral chewing for 20 seconds. The results showed that under physiological load, oral mucosa distortion has two distinct phases: a fast initial displacement as load is applied and a slower and incomplete recovery when load is removed. Intermittent loading such as chewing progressively reduces the magnitude of the denture displacement and the recovery of the mucosa is gradually more incomplete.
