1.The semi-adjustable role in the treatment of Kennedy I+II edentulous patients by the removable partial dentures
Journal of Medical Research 2005;34(2):59-62
60 Kennedy I+II edentulous patients were treated by the removable partial dentures and divided into two groups. In the first group, the semi-adjustable articulator Quick Master was used for 30 patients in the arrangement of the artificial teeth. In the second group, the simple (hinge) Oswung articulator was used. Results showed that the semi-adjustable articulator has better effect in comparison with the hinge articulator. The length of the correcting occlusal discrepancies was shorter when the semi-adjustable was used.

In fully edentulous cases, which are accompanied by severe residual ridge resorption and impairment of supporting tissues of complete dentures, proper diagnosis and systemic treatment planning are required for the improvement in retention, stability, and support of prosthesis. Provisional restoration, while it is unfamiliar in complete denture restoration, can be used as a valuable tool, which makes possible to evaluate the stability of complete dentures and receive feedback from patients in complex clinical situations. In this case, a provisional denture was used to improve stability of impression, polished, and occlusal surfaces of complete denture, and to consider esthetic requirements before final denture construction. The result was clinically satisfactory in terms of functional and esthetical aspects.

OBJECTIVE:
This study aims to evaluate the occlusal characteristics of full edentulous patients with implant-supported prostheses and to provide a reference with the occlusal situation for clinicians.
METHODS:
A Teetester occlusal analysis system was used with 30 full edentulous patients of implant-supported fixed denture (test group) in comparison with 30 natural dentition (control group). The percentage of occlusal force distribution were measured, as well as the occlusal time at the intercuspal, protrusion, and left and right lateral positions.
RESULTS:
Compared with control group, the occlusion time, maximum occlusal force in intercuspal of test group significantly reduced (P<0.05); while control group was obviously superior to test group in the left and right bit force degree. Disclusion time in protrusion, occlusion times in lateral positions of test group also significantly reduced (P<0.05). There were no significant differences in average occlusion force, percentage of total force in anterior teeth, and lateral occlusion between test group and control group.
CONCLUSIONS
The maximum occlusal force in intercuspal of full edentulous patients with implant-supported prostheses reduce. The occlusal force in protrusive occlusion is concentrated in the front teeth, and the group function occlusion is the main lateral occlusal pattern.

4.Rehabilitation of a patient with atrophic ridges using gothic arch tracing and nonpressure impression: a case report
Journal of Dental Rehabilitation and Applied Science 2018;34(3):232-238
Flabby ridges adversely affect the stability of complete dentures. For the management it is suggested that soft tissues reconditioned before making definitive dentures, and modified impression techniques used for the flabby ridges. Also, correct record of centric relation is important in complete dentures. This case of 67-year-old edentulous female patient had atrophied ridges on the mandible and the flabby ridge on the maxilla. Treatment dentures were fabricated using gothic arch tracing method and tissue conditioner. Definitive dentures were made using window opening impression technique, the gothic arch tracing method, and lingualized occlusion. The patient was satisfied with the function and esthetic quality of the new prostheses.

Conventional denture impression techniques have limitations for edentulous patients with severe alveolar bone resorption and can cause problems from excessive border extension. Especially when a patient has movable tissue it is difficult to make accurate impression, thus might interrupt stable seating of complete denture. Fabrication of complete denture using closed mouth technique for edentulous patient with severe ridge resorption is thought to provide better stability and retention. In this case, an 86-year-old patient had both edentulous jaws with epulis fissuratum on maxillary anterior ridge and severe mandibular ridge resorption. Thus, tentative vertical dimension was determined by using Centric tray and individual tray attached with gothic arch tracer was fabricated. Complete denture was fabricated using closed mouth technique and the patient was satisfied with better stability and retention of the complete denture.
