Precise jaw relation recorder: An innovative device for prosthodontic rehabilitation.

BACKGROUND: The orchestration of jaw relations in edentulous scenarios poses a significant challenge, demanding acumen, and expertise from the clinician. A myriad of devices, substances, and methodologies are employed to gauge the transverse, vertical, and horizontal spectrums of jaw relations. Traditionally, a synthesis of assorted devices and techniques has been requisitioned to chronicle the spatial dynamics between the maxilla and mandible. Yet, the absence of a solitary apparatus capable of concurrently documenting the triad of jaw relations has been a notable lacuna in prosthodontic rehabilitation. PURPOSE: This discourse expounds on an innovative contrivance, termed the Precise Jaw Relation Recorder. This pioneering instrument is adept at capturing the tripartite jaw relation processes: the occlusal plane's alignment in parallelism to the ala-tragus line, the vertical dimension at repose, and the occlusion as well as the centric relation. The device's strategic utility lies in its ability to facilitate the creation of prostheses that are not only functionally superior but also aesthetically more pleasing. CONCLUSION: Its implementation is a stride toward refining the accuracy of prosthodontic outcomes, thereby elevating the standard of patient care in dental practice.

Comparison of accuracy of protrusive condylar guidance registration by two interocclusal recording materials in edentulous patients.

Background and Purpose: During complete denture fabrication making Interocclusal records plays an integral role to obtain the condylar guidance value. The study was conducted to compare the protrusive condylar guidance registration by two interocclusal recording materials-Quick setting plaster and Luxabite®(bisacrylic composite) in semi adjustable articulator for completely edentulous patients. Methodology: Maxillary and Mandibular casts of the completely edentulous patients were mounted in Hanau®Wide Vue articulator. The Quick setting plaster and Luxabite®(bisacrylic composite) was used as interocclusal recording materials to program the protrusive condylar guidance angles in the articulators. Results: The protrusive condylar guidance values registered in the articulator for the different interocclusal records were tabulated and statistically analyzed.. The mean protrusive condylar guidance values registered in the articulator was compared with two parameters obtained from the radiographic tracings -- the protrusive condylar path angle obtained with Quick setting plaster and Luxabite with the inclination of articular eminence to the Frankfort horizontal plane. Conclusion: From the study it was concluded that the Luxabite®(bisacrylic composite) material demonstrated better reproducibility of protrusive condylar guidance registration.than the Quick setting plaster.

Résumé Contexte et objectif: Pendant la fabrication complète de la prothèse de prothèse, la fabrication des enregistrements d'interoccluse joue un rôle essentiel pour obtenir la valeur de guidage condylien. L'étude a été réalisée pour comparer l'enregistrement de guidage condylien en saillie par deux matériaux d'enregistrement interocclusal - Platter en plâtre et Luxabite® (composite bisacrylique) dans un articulateur semi-réglable pour les patients complètement édentés. Méthodologie: Les moulages maxillaires et mandibulaires des patients complètement édentés ont été montés dans l'articulateur de Hanau® à large de Vue. Le plâtre à réglage rapide et Luxabite® (composite bisacrylique) ont été utilisés comme matériel d'enregistrement interocclusal pour programmer les angles de guidage condyliennes en saillie dans les articulateurs. Résultats: Les valeurs de guidage condylien en saillie enregistrées dans l'articulateur pour les différents enregistrements interocclusaux ont été tabulées et analysées statistiquement. Les valeurs de guidage condyliennes en protruments moyennes enregistrées dans l'articulateur ont été comparées à deux paramètres obtenus à partir des tracages radiographiques - le protruments de l'angle de trajectoire condylien obtenu avec un plâtre rapide et luxabite avec l'inclinaison d'une éminence articulaire au plan horizontal de Frankfort. Conclusion: D'après l'étude, il a été conclu que le matériau Luxabite® (composite bisacrylique) avait démontré une meilleure reproductibilité de l'enregistrement de guidage condylien en saillie que le plâtre de réglage rapide. Mots-clés: Guidage condylien, édenté, facebow, plan horizontal de Frankfort, dossier interocclusal, radiographie céphalométrique latérale, guidage condylien en saillie, articulateur semi-réglable.

Knowledge and Awareness of Jaw Relation among Dental Interns: A Questionnaire Survey.

AIMS: This study aims to explore the awareness among the interns regarding the jaw relation procedures. Jaw relation is one of the most important criteria for the fabrication of complete dentures to provide a satisfactory oral function for the aging population. SETTINGS AND DESIGN: The study design was a descriptive survey. MATERIALS AND METHODS: A self-administered questionnaire was designed and distributed among 202 interns in three different colleges in Salem and Namakkal in Tamil Nadu using Stratified Proportionate Random Sampling Technique. The survey included a questionnaire with ten questions to assess the knowledge and awareness of jaw relation procedures among the interns. STATISTICAL ANALYSIS USED: The statistical tools used to analyze the levels of awareness among the interns were frequencies and percentage analysis. Chi-square tests and logistic regression were used to investigate the relationship between awareness among interns, with respect to gender, age, and complete dentures done, with the level of significance at P < 0.05 using Microsoft Excel and SPSS software version 23. RESULTS: The awareness prevalent regarding jaw relation and its procedures among the respondents was 83%. There was a statistically significant relationship between maximum complete dentures done and awareness among interns (P < 0.001). Complete dentures made a significant contribution to the prediction of awareness (P < 0.0001). CONCLUSION: To improve the awareness among the interns increased educational programs, clinical training and greater patient exposure to the clinical application of jaw relation procedures to construct complete dentures are needed during their undergraduate education.

Partial Edentulousness in a Rural Population Based on Kennedy's Classification: Epidemiological Study.

INTRODUCTION: Edentulousness falls in a special category among the various conditions of dental origin. A simple estimation of the partial edentulous condition is a rough indication of the prevalence of dental diseases and success or failure of dental care. METHODOLOGY: In this study a cross sectional survey was carried out among 1000 patients of rural population in JKK Nataraja Dental College, Komarapalayam, Namakkal District, Tamilnadu, India. The aim of this study was to evaluate the epidemiological features of partial edentulous condition in the age group of 30-60 years in a rural Population based on the Kennedy classification. A pre tested questionnaire was Used in this study. RESULT: Chi-square test was conducted and results were obtained and P value <0.05 was considered stastically significant. CONCLUSION: The study revealed Kennedy Class III partially edentulous condition was more common than other conditions. There is significant correlation between lack of awareness, education and socio-economic status in relation to loss of teeth among population.

Evaluation of Efficiency of Different Decontamination Methods of Dental Burs: An In vivo Study.

INTRODUCTION: Infection control is very important in dentistry. Both dentist and patients are at risk of communicating diseases during treatment procedures. Dental burs have been identified as a source of cross-contamination between patient and dental personnel. AIM: The present study was done to quantitatively and qualitatively assess the pathogenic contamination of dental burs used for tooth preparation and to determine the effective method of sterilization(autoclave, glass bead sterilizer, hot air oven and surgical spirit immersion) of burs used for crown preparation. METHODOLOGY: Dental burs were assessed before and after tooth preparation, also after sterilization burs were evaluated. CONCLUSION: Findings of our study revealed that among the experimental groups used in the present study, Autoclave and Hot air oven was found to be the relatively best method to sterilize burs. Proper cleaning and sterilization of burs should be strictly employed to prevent cross contamination in clinical practice.

"Denture marking" as an aid to forensic identification.

"Identification through forensic science is an art of giving the corpse a name A real life detective work that would put even Sherlock Homes to shame." Forensic dentistry deals with proper handling and examination of dental evidence and proper evaluation and presentation of dental findings in interest of justice. Denture marking or labeling is not a new concept in either Prosthetic or Forensic dentistry and its routine practice has been urged by Forensic dentists internationally for many years. Denture marking is accepted as a means of identifying dentures and persons in geriatric institutions or post mortem during war, crimes, and civil unrest, natural and mass disasters. Prosthodontists are playing very important role in forensic dentistry as they are concerned with fabrication of various prostheses which can serve as an important tool for identification. Identification is essential requirement of any medico-legal investigation because a wrong identity may pose a problem in delivering justice. The main objective of this article is to discuss the various methods of denture marking and to emphasize the importance of denture marking for person identification in medico legal investigations.
