Aim: The aim of this study is to evaluate the influence of occlusion on body posture and plantar arch pressure. Settings and Design: An Observational analysis to Analyze the Influence of Occlusion on Plantar Pressure and Body Posture. Materials and Methods: A total of 30 asymptomatic subjects were selected for the study including 18 females and 12 males from age group 22 years to 28 years with a mean age of 24.83 years. Each subject underwent evaluation of occlusion at MIP using a Digital Occlusal analyzer (T-Scan III). At this point, the subjects were made to stand on a mat scan which consisted of a large postural platform sensor and a computer that displayed the plantar pressure data. The computer connected to the T Scan displayed the occlusal pressure analysis. This was followed by an evaluation of body posture using a posture grid where the photographs were taken and an evaluation of the frontal and lateral photos was done using the APECS -- posture analysis app. Statistical Analysis Used: Statistical package for social sciences (SPSS) for windows version 22.0 Released 2013, Armonk, N Y: IBM Corp., was used to perform Statistical Analysis. A chi-square test was applied for qualitative variables to find the association. Paired t-test was applied to compare the changes in the quantitative parameters in eye-open and eye-closed conditions. The level of significance was set at 5%. Results: As observed from the results, occlusion for 40% of the subjects, where n = 12, was dominant on the right side. Occlusion for 23.3% of subjects, where n = 7, was dominant on the left side. Whereas, for 36.7% of subjects, where n = 11, the pressure distribution was almost equal on both sides. The inclination of body posture for 23.3% of subjects, where n = 7, was towards the right side. The inclination of body posture for 50% of subjects, where n = 11, was towards the left side. And, the inclination of body posture for 26.7% of subjects, where n = 8, was neutral i.e., balanced on the right and left side. Plantar pressure for 6.7% of subjects, where n = 2, was dominant on the right side. Plantar pressure for 36.7% of subjects, where n = 11, was dominant on the left side. Whereas, for 56.7% of subjects, where n = 17, the plantar pressure distribution was almost equal on both sides. Conclusion: On correlating the three parameters, it was found that occlusion for most of the subjects dominated on the right side, while body posture and plantar pressure dominated on the contralateral i.e., left side.

Background: High occlusal forces in patients with untreated periodontitis may reflect occlusal trauma-associated periodontal conditions. Occlusal analysis using T-scan might provide the distribution of occlusal loading forces in periodontitis patients. The study aimed to evaluate the effect of occlusal trauma in periodontitis patients and occlusal calibration using a T-scan. Materials and Methods: A total of 30 periodontitis patients were recruited for the study. Patients were categorized into two groups: Group I: scaling and root planing followed by T-scan recording and no occlusal calibration; Group II: scaling and root planing followed by occlusal calibration using T-scan. Clinical parameters, orthopantomogram (OPG) and T-scan evaluation were evaluated at baseline, 3-month and 6-month intervals. Results: Significant improvements in clinical parameters were noted at different time intervals after occlusal calibration using T-scan. At 3-month intervals, mean pocket depth showed statistically significant difference among the test group in the right (upper and lower) and left lower quadrant at P = 0.01, 0.002 and 0.005, respectively. Mean clinical attachment level (CAL) showed statistically significant difference among the test group in the right upper, right lower and left lower quadrants at P = 0.02, 0.001 and 0.009, respectively, at 3 months. The comparison of the mean gingival index (GI) at 6 months showed statistically significant difference among test and control groups at 6 months in different study quadrants (P = 1 in right upper, 0.009 in right lower, <0.001 in left upper and <0.001 in left lower). Mean pocket depth at the 6-month follow-up showed statistically significant difference among the test group in all the study quadrants (P = <0.001 in right upper, <0.001 in right lower, 0.003 in left upper and 0.005 in left lower). Mean CAL showed statistically significant difference among the test group in all the study quadrants at 6-month intervals (P = 0.02 in right upper, <0.001 in right lower, 0.01 in left upper and 0.04 in left lower). The bone defect height showed a statistically significant difference only in the right upper quadrant among both the test groups at the 6-month follow-up (P = 0.02). Comparing the mean percentage of force on both sides of the jaw showed a statistically significant difference among the test group at 6 months (P = 0.001 on the left side and 0.001 on the right side). Conclusion: The occlusal correction using T-scan showed a positive association between probing pocket depth (PPD) and CAL at different time intervals from baseline to 6 months when these parameters were compared after occlusal adjustments.

To assess the five-year long-term quality of life of patients who were treated with Disclusion Time Reduction Therapy (DTR). Thirty occluso-muscular disorder patients responded to two questionnaires about their symptom intensities, frequencies, and pain levels that were given to the patients before DTR therapy and five years after. Both surveys were subjected to the Wilcoxon signed-rank test to compare differences in the reported intensities, frequencies, and pain levels. A statistically significant reduction was found between the pre- and five-year post-DTR treatment intensities, frequencies, and pain scores (p < 0.05). The chronic pain intensity and frequency observed in patients with occluso-muscular disorders can be markedly reduced by Immediate Complete Anterior Guidance Development (ICAGD)/DTR therapy, while improving the patient's overall long-term quality of life. Many pre-ICAGD/DTR daily chronic and painful, occluso-muscular symptoms were no longer present years after undergoing ICAGD/DTR treatment. [ABSTRACT FROM AUTHOR]

Surgical guides (SGs) have been commonly used in full-mouth rehabilitation and numerous advances have been adopted in their development. However, they have been restricted to implant placement and are later rendered useless. They further add to the burden of biological waste management following their limited use. The quantum of technologies and materials used to make us ponder if they can be used further. This article establishes different ways of using SG in different stages of prosthetic phase of treatment by demonstrating the procedures clinically. It gives us an insight into how the guides can be used for implant localization and exposure during the secondary surgical phase and also during impression making, thereby enhancing the treatment outcome.

Purpose: The purpose of the study was to analyze and compare the stress distribution in the so-called All-on-Four concept where two anterior implants were placed parallel to each other and two posterior implants were tilted at 45° angle against the four parallelly placed implants within the interforaminal distance in an edentulous mandible. Materials and Methods: The three-dimensional finite element analysis models consisted of cancellous bone surrounded by the cortical bone, four dental implants positioned in two different designs – i.e., four parallelly placed implants (Model 1) and All-on-Four concept (Model 2) with hybrid superstructures comprising of a Hader bar. The vertical (60N, 130N, and 300N) and lateral (20N, 45N, and 100N) loading protocols were considered and von Mises stress values were determined. Results: On vertical and lateral loading, lower stress concentrations were observed in the peri-implant region in Model 2. However, there was higher stress concentration noticed on cortical, cancellous bone and bar attachment due to the tilting of implants in every condition. Conclusion: Within the limitations of the study, All-on-Four concept is an optimal and viable treatment option if executed accurately as it reduces the cantilever length, reduces stress concentrations in the peri-implant region, and is cost-effective.

Although a number of approaches to implant-supported restoration of severely atrophic maxillae and mandibles have been developed, most of these treatments are costly and protracted. An exception is the all-on-four concept, which uses only four implants to support an acrylic, screw-retained provisional prosthesis delivered on the day of implant placement, followed by a definitive prosthesis later on. The present article describes about full-arch rehabilitations using implants supported prosthesis by "DIEM 2/all on 4" technique. This is an innovative technique that allows for immediate function, full arch implant-supported prosthesis without the need for any bone grafting procedures even in atrophic situations. In this technique, four implants are placed in the anterior region of the jaw between the two mental foramina in the mandible and between the mesial walls of maxillary sinus in the maxilla. The two anterior implants follow the jaw anatomy and the two distal implants are tilted at 45° angulation posteriorly, this arrangement allowed for good implant anchorage, short cantilever length, and large inter implant distance thus favoring fruitful outcome of the treatment.

The ideal goal of modern dentistry is to restore the patient to normal contour, function, comfort, esthetics, speech, and health. A dentist provides restoration either by removing caries from a tooth or by replacing several teeth. Implant dentistry is unique because of its ability to achieve this goal regardless of the atrophy, disease or injury of the stomatognathic system. Endosseous dental implants are used to retain and/or support for fixed or removable prosthesis in completely or partially edentulous patients. Successful long-term results of dental implants have led to an increase in their usage in many clinical situations. Although Implantology has advanced, failures also may occur with this type of treatment. The clinical success of an implant treatment is largely determined by the manner in which the mechanical stresses are transferred from implant to surrounding bone without generating forces of magnitude that would jeopardize the longevity of implant and prostheses. The present study was done to evaluate the strain around Endosseous Threaded and Non-Threaded implant opposing maxillary natural tooth with Regular and Altered occlusion by using 3-D Finite Element Analysis.

Restoration of the lost structure can be achieved by using simple conventional removable partial dentures, cast partial dentures, precision or semi precision attachment system for a removable partial dentures, telescopic dentures and dental implants. Fabrication of fixed prosthesis becomes difficult if a patient exhibits a highly reduced dentition with regard to number of teeth lost due to caries or periodontal disease. Patient's systemic factors do not favour Implant placement. Treatment utilizing attachment prosthesis and cast partial denture must follow the biologic tenets of basic fundamental principles.

Tooth wear and discoloration is a normal process in the life time of an individual. Severe wear and discoloration can result in cosmetic concern and loss of vertical dimension. These problems can best be treated by giving fixed prosthesis. This case provides the management using the concept of Minimally Invasive Cosmetic Dentistry (MICD) with Ceramopolymer as the restorative material. Computer Guided Occlusal Analysis (CGOA) was used for establishing uniform occlusal force distribution. [ABSTRACT FROM AUTHOR]
