Digital dental tape- magical tape

Abstract

S16 The Journal of Indian Prosthodontic Society | Volume 20 | Supplement 1 | December 2020 Introduction: Edentulism is the major problem in the elderly population. Loss of retention and stability of the lower denture can be overcome by implants to improve their masticatory efficiency, and quality of life. So, the aim of this study was to evaluate and compare the masticatory efficiency of single and double implant retained overdenture and assess their oral health related quality of life by questionnaire method. Methodology: Twenty edentulous patients with inclusion and exclusion criteria divided into two groups, provided Conventional complete denture (CCD) to all patients. Objective evaluation (surface EMG) was done after 3 months, followed by placement of implantsGroup I (SIOD) with single implant and group II with two implants (DIOD). Delayed loading was followed. Surface EMG evaluation was done again after 3 months usage of dentures. Subjective evaluation was done using OHIP 20 questionnaire before and after implant placement. Result: Statistically analysis of EMG results found that there was statistically significant difference (p<0.05) between CCD and SIOD, CCD and DIOD, DIOD and SIOD respectively. In Subjective evaluation by questionnaire method, though there was significant difference found between CCD ad SIOD, CCD and DIOD respectively, there was no statistical difference (p > 0.05) between SIOD and DIOD. Conclusion: This study revealed that single implant retained overdenture improved masticatory efficiency and the patient satisfaction was similar to both SIOD and DIOD respectively. So this study concluded that single implant may be good alternative to two implant retained overdenture in patients who cannot afford to two implants DOI: 10.4103/0972-4052.306339 Digital dental tapemagical tape Dr. Prajna Prakash Shetty Rajarajeswari Dental College & Hospital, Bangalore Introduction: Vertical dimension of occlusion (VDO) has been defined by glossary of prosthodontic terms as the distance between two selected anatomic or marked points (usually one on the tip of the nose and the other on the chin) when in maximal intercuspal position. Inaccurate vertical dimension recording can result in an array of problems. It can cause a multitude of adverse effects in aesthetics, temporomandibular joints, functional efficiency, and masticatory muscles disorders and affect the facial expression of the individual. The various methods to determine the vertical dimension can be broadly classified as Pre and Post extraction methods. However, none of them have been able to give an accurate real time measurement of vertical dimension without any error. Hence there was a requirement to fabricate an instrument that can provide a real time value of the distance between two points on the face without any error. This presentation describes a simple tool that has been made for recording a patient’s accurate vertical dimension in a digital fashion. Methodology: Field of invention: The present invention is related to the fabrication of a dental instrument, and more particularly a tool for recording a patient’s accurate vertical dimension in a digital fashion. Description of the Sensor: A small sensor is to be fabricated which can be placed in two immovable parts of the face. The patient is asked to relax by saying m syllables. The values are automatically recorded through the Bluetooth on any android phone. This value can be re recorded and saved for further reference. Principle of working: UV source & detectorTransmits the signal and the signal is reflected back by the obstruction. The reflected echo signal is picked up by the detecting circuit. The electronic circuit amplifies the signal and sends it to the microcontroller. The electronic circuit is a part of the sensor/detector circuit. The microcontroller is programmed to convert the time to distance and displays the distance measured in cms. Arduino board is used for developing the proposed device. The distance is displayed only when the dentist activates the switch, once he is sure the patient is in right position. The minimum distance measured with the device is 3 cms. The normal distance is around 6-7 cms. Result: This instrument has been used on patients a pilot study was conducted. The study reveals 1oo percent accurate due to absence of human error. We are making a sensor, which can automatically record the vertical dimension in real time without any distortion or any doctors assistance, making it an accurate and flawless reading. This device is sent for patent Under Indian patent office. Conclusion: The digital dental tape will definitely come up as a magical tape for getting real time distance and values. The plethora of uses will be 100 percent accuracy with little technique sensitiveness and increased patient comfort and acceptance.

Sri Venkateshwaraa Dental College, Puducherry Introduction: Existing literature is chaotic on factors contributing to the success of complete denture treatment. Therefore, this study considered communication skills, the often ignored most pertinent factor, to assess its role in the success of complete denture treatment.
