Proper occlusal plane is an essential consideration when multiple long span posterior restorations are designed. The determination of the occlusal plane can have a profound effect on the short and long term success of a restorative case. Purpose of Study. (1) To determine the appropriate occlusal curve for individual patients. (2) To compare the deviation of the clinical occlusal curve with the ideal ones. Materials and Methods. A total of 20 subjects were examined and study models were made of their maxillary and mandibular dentition. Inter-occlusal records were made and the casts were articulated in semiadjustable articulator. An ideal occlusal plane was created. The distance of the farthest cusp tip from the Broadrick curve was measured along the long axis of the tooth for each individual. Paired t-tests were used to compare the findings between subjects and controls. Results. A statistically significant difference P < 0.05 was found in the deviation from the Broadrick curve between patients who have lost posterior teeth and the control group who had a full dentition with no missing teeth. Conclusion. Proper utilization of the broadrick flag on a semi-adjustable articulator will allow for a correct determination of the occlusal plane.

Aesthetic reconstruction of original contours is one of the important goals of prosthodontic treatment. Restoration of missing teeth, masticatory function, speech and providing support to the lips and cheeks is prime goal of removable prosthetics. The cheeks lose their support in aged and edentulous individuals. Cheek lifting appliance or cheek plumper is a prosthesis that support and lift the cheeks for aesthetics. This article describes a clinical case where a cheek plumper is being innovatively made detachable by the use of hooks made from orthodontic wire attached to complete denture prosthesis.

All-ceramic restorations have been used for long as restorative material in dentistry. However, the recent advances in both the material and technology of all-ceramic have made them a more viable treatment option. Several practitioners hesitate in giving this option to patient for fear of failure. This article describes all the failures of all-ceramic material and how to prevent them. In particular, the article highlights various errors that clinicians make while preparing tooth to receive all-ceramic restorations and how to rectify them.

This paper presents vibration behavior of ring stiffened polymer composite thick shells used for underwater structures. Filament wound shells stiffened with internal and external rings and with hemispherical ends were tested for vibration in air and water in free-free boundary condition using roving hammer and fixed response method. Modal testing of the shells was performed under hydrostatic loading in a custom designed buckling tester for determining natural frequency at higher sea depths. Accelerometer was mounted on the inner surface of the shell. It was excited using a plumbob, rope and pulley arrangement. Experimental results were validated by modal analysis using Hyperworks and ANSYS. Vibration behavior in water was simulated by Fluid structure interaction approach. Experimental first natural frequency in water was lesser than that in air. With increase in hydrostatic pressure, the shell showed moderate variation in natural frequency. The experimental and numerical results of natural frequency and mode shapes were in good agreement with each other. Natural frequencies were lower in long and thick shells.

In the current scenario, facial appearance of the patient is of prime consideration during rehabilitation. The aesthetics of the edentulous patient are greatly affected due loss of alveolar bone, loss of muscle tonicity which may be lead to undesirable hollowing of cheeks with age. Cheek plumper is a frequently used, non-invasive, simple prosthesis to support the sunken cheeks and help itscost effectiveness.

Successful prosthetic treatment depends on the functional and esthetic outcomes of the treatment and occlusal plane is a factor that can influence both these outcomes. Identifying and correcting occlusal plane alterations using Broadrick's occlusal plane analyzer positively influences the treatment outcomes. Incorporating aesthetic acetal resin clasp in cast partial dentures is beneficial for patients seeking efficient, affordable and aesthetic treatment option. This article presents a case report where a simplified custom made Broadrick's occlusal analyzer was used to identify the altered occlusal plane and aesthetic acetal resin clasp were given in the maxillary cast partial denture for improved aesthetics.
