A patient with malunited fracture of mandible require preprosthic reconstructive surgery followed by implant-assisted overdentures. In this case report, conventional complete dentures were fabricated for the patient as he refused any invasive treatment. The fabrication procedure of the denture was carefully modified according to anatomical and functional situation of the patient to achieve adequate retention and stability. Complete dentures thus fabricated provided comfort and sufficient function to the patient.Keywords

Aim:1 .The aim of this study was to investigate the average maximum range of inter-incisal mouth opening in a representative sample of the adult subjects of Haryana. 2. To see any correlation between maximal inter-incisal opening with age.Methods: Maximum mouth opening was studied in 756 adult subjects with age range of 20-50 years in Yamunanagar, Haryana. Age limit was further divided into three groups (20-30, 31-40, 41-50). Those with clinical history of TMJ involvement, OSMF, any trauma, odontogenic and non-odoritogenic infections, dental prosthesis on the anterior teeth, congenital anomalies in the maxillofacial region were excluded from this study. The measurements were recorded twice and mean of the two values were taken.
Statistical Analysis: Independent sample t-test was calculated to compare age and mouth opening in both male and females respectively. Bivariate pearson correlation was used to see any relationship between age and mouth opening. P-value ≥ 0.05 and Cl (confidence interval) at 95% were considered statistically significant.
The Results: The average mouth opening of males (45.36 ± 6.70 mm) subjects was higher as compared to female (41.27 ± 6.75 mm) with significant, p-value 0.000. The mean mouth opening ±SD for both sexes combined was 43.39 ± 7.02 mm. The corresponding values for mean inter-incisal opening in male population aged 20-30, 31-40, 41-50 were 45.52 ± 7.15, 46.16 ± 5.47, 42.96 ±6.82 mm and in female population aged 20-30, 31-40,41-50 were41.40 ± 7.08, 41.60 ± 6.29 and40.03 ± 6.38 nim respectively.
Conclusion: Maximal mouth opening differ significantly with gender. There is a decrease in MMO with older age group.

- To Evaluate the Marginal Fit of Metal Copings Fabricated by Conventional Casting Procedure and Direct Metal Laser Sintering Technology-An in Vitro Study
Abstract Views :287 |
PDF Views:91
Materials and method: Forty tooth preparations were carried out over extracted mandibular molars. They were divided into two groups A and B of 20 each. For group A Co-Cr copings were fabricated by direct metal laser sintering (DMLS) and for group B by lost wax technique (LW). Glass-ionomer cement (GIC) was used to tack the copings over their preparations. Marginal fit was then evaluated directly under the stereomicroscope.
Results: The mean marginal gap of group A was 27.9±2.4 μm and group B was 40.4 μm. Statistical analysis using t-test showed highly significant difference (P>.05) between the marginal mean of the DMLS (group A) compared to LW (group B).
Conclusion: The DMLS copings demonstrated superior marginal fit compared to that of conventional Co-Cr casted copings.
