The study compares subjective experiences of patients, wearing complete dentures. Two different methods of determining a centric relation were performed: the traditional method using wax occlusal rims and the Gerber method, based on gothic arch tracings. The success rate of establishing a centric relation in both methods was evaluated (rentgenodiagnostics). The influence of the method used to obtain the centric relation on patients’ stomatognathic system (condyle centralization, pain) was also evaluated. Better results were achieved in gothic arch tracing method. Before every prosthetic treatment of edentulous patients, a functional analysis of the TMJ is necessary. The lack of centric relation, in a long term adaptation patients, does not lead to TMD symptoms. This trial is registered with NCT03343015.

Background & Objectives:The study was conducted with objective to compare the horizontal condylar guidance (HCG) obtained by protrusive interocclusal records and panoramic radiographic images in completely edentulous patients.Materials & Methods:The horizontal condylar guidance was measured in 25 completely edentulous patients by protrusive interocclusal records using zinc oxide eugenol paste through a face bow transfer (HanauTM Spring bow, Whip Mix Corporation, USA) to a semi-adjustable articulator (HanauTM Wide-Vue Articulator, Whip Mix Corporation, USA).  In the same patients, HCG was traced in the panoramic radiograph. The angles formed by the intersection of two lines: Frankfurt’s horizontal plane and posterior slope of articular eminence was measured using protractor to represent the horizontal condylar guidance angle on each side.Results:The mean difference between the horizontal condylar guidance angles values obtained using protrusive interocclusal record and panoramic radiograph was 2.68 degrees and 3.40 degrees for the right and the left side respectively, with the panoramic radiograph values being higher. This difference between the values was found to be highly significant between the two methods for the right side (t = 2.70, p = 0.012) and left side (t = 3.69, p = 0.001). A significant positive correlation was found between the horizontal condylar guidance obtained from protrusive interocclusal record and panoramic radiograph for the right (r = 0.643, p = 0.001) and left sides (r = 0.622, p = 0.001) separately.Conclusion:The panoramic radiographic tracing can be used to calculate the mean horizontal condylar guidance in the completely edentulous patients and these values can be used to programme semi-adjustable articulators avoiding the cumbersome process of obtaining protrusive interocclusal records.

Background: Knowledge about the type & position of mental foramen is very much important landmark for dentists to perform any surgical procedure in the vicinity of mental foramen. The pur­pose of this study was to determine the most frequently occurring type & position of the mental foramen in Chitwan population using digital Panoramic Radiograph. Methods: This cross-sectional retrospective study was conducted on 500 (250 Male& 250 Female) digital panoramic radiograph which were collected from the department of Oral Medicine & Radi­ology. The type & position of Mental Foramen was analysed with Dicom viewer. The data obtained was statistically analyzed by with descriptive and inferential statistics using SPSS Version 20. Result: The most common type of mental foramen was Type 3 (diffuse with a distinct border of the foramen) & the test showed significant difference by gender. The most common position of mental foramen was position 4 (in line with second premolar) followed by position 3 (Between the first & second premolar) with no significant difference with gender with p-value <0.05. Conclusions: This study shows that the most frequent appearance of mental foramen lies in the line of second premolar. So this finding is used as a guide line in Chitwan population to perform various type of dental surgical procedure safely in mental foramen region but the accurate radio­graphic identification of mental foramen is paramount.

Objectives: The aim of our study was to compare peri-implant bone loss at implants placed in alveolar sockets filled with a particulate allogenous bone graft (DFDBA 300-500 µm) and platelet concentrates versus at implants placed in the native bone. Materials and Methods: A retrospective clinical study was performed. A total of 84 patients were included with 247 implants for the restoration of mono and pluri-radicular teeth: 169 implants in native bone and 78 in socket-grafted bone. The peri-implant bone loss was measured by 2 independent operators at 6 and 12 months. Results: The overall mesial and distal peri-implant bone losses were 0.9 ± 0.7 mm and 0.9 ± 0.8 mm at 6 months, respectively, and 1 ± 0.65 mm and 1.2 ± 0.9 mm at 12 months, respectively. In the tested group, the bone loss was 0.8 ± 0.8 mm at 6 months and 1.2 ± 0.9 mm at 12 months. In the control group, the bone loss was 1.0 ± 0.7 mm at 6 months and 0.95 ± 0.6 mm at 12 months. There were no statistically significant differences in bone loss between the two groups. Taking both groups together, there were no statistically significant difference in bone loss between patients with or without histories of periodontitis, but there was a statistically significant difference in bone loss between the mandible and maxilla as well as between unitary and total edentations and between partially and total edentulous patients. Conclusion: At 6 and 12 months, the peri-implant bone loss in sockets preserved with DFDBA and platelet concentrates was similar to the peri-implant bone loss in native bone.

Introduction: The documentation of the maxillomandibular relationship and the recording values of condylar guidance is the most critical, yet essential step in fabrication of complete denture prosthesis and it also helps in diagnosing, treatment planning, and fabrication of the balanced complete denture prosthesis that aids in enhancing the aesthetics, and maintenance of the stomatognathic system. Various techniques are available to record the condylar guidance; One of them being axiographic technique and panoramic radiograph followed by programming the semi adjustable articulators. Aim: The aim of the present study was to evaluate and compare the condylar guidance using the conventional technique the gothic arch tracing with that of axiographic technique and the panoramic radiographs. Materials and Methods: The observational study with the clinical set up was carried out over a period between October 2018- March 2019. Twenty completely edentulous patients were selected for the study. The comparative evaluation of axiographic tracing technique, panoramic radiographic technique and the extraoral gothic arch tracing technique was conducted. The horizontal condylar guidance values obtained with these techniques were assessed. The data obtained was statistically analysed using Karl Pearson correlation test to determine the correlation between the values obtained from all the three techniques on the right side and the left side of the subjects. Paired t-test and Bonferroni Post-Hoc test were used to compare the extraoral gothic arch tracing values and Orthopantomogram values and axiographic tracing values on right side and left side of the subjects. Results: A statistically significant correlation was observed between the extraoral Gothic arch tracing technique and the panoramic radiographic technique on right (r=0.047, p-value 0.04) and left sides (r=0.55, p-value 0.01) of the subjects. The axiographic tracing showed lower values when compared with gothic arch tracing technique and the panoramic radiographic technique. (95%CI of difference was -0.49 lower). Significant differences were obtained on comparison between all three techniques on right (p-value<0.001) and left sides.(p-value 0.008). On pairwise comparison of right sides between Extraoral gothic arch Tracing and Axiographic tracing (p-value<0.001) and between axiographic tracing and Orthopantomographic tracing (p-value<0.001), were significant, while pairwise comparison on left side between Orthopantomogram and Axiographic tracings (p-value 0.01) was significant. Conclusion: The panoramic radiographic images can be used as an alternative method to that of conventional gothic arch tracing technique to obtain the condylar guidance values. The values obtained using axiographic tracings method was comparatively lower. Thus, the values obtained from axiographic technique should be used with caution or the values needs to be compared to gold standard techniques to further analyse the accuracy of the values that can be used as a valuable aid in setting the condylar guidance in semi-adjustable articulators.
