EVALUATION OF TWO METHODS USED TO RECORD THE NEUTRAL ZONE UTILIZED LOW FUSING MODELING COMPOUND- ACCURACY OF CENTRIC RELATION REGISTRATION

Background: The condylar position discrepancy between centric relation and maximal intercuspation has been still a controversial issue. Aims: To compare the condylar position between centric relation and maximal intercuspation using cone-beam tomography in patients without temporomandibular joints disorder. Materials and methods: To assess the condylar position in centric relation and maximal intercuspation using cone-beam tomography on 40 fifth-year and sixth-year dental students of Hue University of Medicine and Pharmacy without temporomandibular joints disorder. The condylar positions are assessed following Sener classification (2009) and are compared between centric relation and maximal intercuspation using pairedsamples t-test and Mann-Whitney U-test. Results: Among 480 condye-to-fossa measurement pairs, there are 91.2% pairs having difference between two reference position but there is no significant difference. The condylar position at the superior of mandibular fossa has the greatest percentage in both centric relation and maximal intercuspation (43.8% in centric relation and 51.2% in maximal intercuspation). This greatest percentage is followed by the condylar position at posterior of mandibular fossa (32.5% in centric relation and 36.3% in maximal intercuspation). Lastly, the condylar position at the anterior of mandibular fossa has the fewest percentage (23.7% in centric relation and 12.5% in maximal intercuspation). Conclusion: There is no significant difference of condylar position between centric relation and maximal intercuspation in patients without temporomandibular joints disorder. Key words: Condylar position, centric relation, maximal intercuspation, cone-beam tomography

This chapter discusses the Polish–Lithuanian War of 1919–20. The war flared in May 1919 when the first open clash took place between Lithuanian and Polish troops. It gradually escalated and lasted until late November 1920 when, in Kaunas, both sides agreed to stop fighting along the demarcation line established by the League of Nations. Yet there was no final peace agreement signed, only a truce. And low-scale paramilitary violence continued unabated in the “neutral zone” along the demarcation line until as late as May 1923. The chapter argues that the war against Poland provided an opportunity for total mobilization of the whole of Lithuanian society. The fact that, during the entire interwar period, the conflict remained open-ended, ensured that the paramilitary structures and military laws that emerged during it would remain in place for much longer.
