Extracted teeth are still considered clinical waste and\u0000 therefore are being discarded. It is evident that obtained and prepared\u0000 autogenous dentin graft (ADG) may be used for guided bone regeneration (GBR)\u0000 due to its similar biochemical characteristics to human bone. The aim was to\u0000 present a novel procedure in a clinical setting that employs freshly\u0000 extracted teeth that are processed into a bacteria-free particulate dentin,\u0000 and then grafted immediately into the extraction sites or bone deffects.\u0000 Monitoring the clinical and radiological parameters (vertical and horizontal\u0000 dimensional changes on the alveolar ridge and vertical dimension of\u0000 intrabony defects at the distal aspect of the second molar after extraction\u0000 of third molar) for a period of 6 months, proved rapid healing capacity of\u0000 ADG on the bone and soft tissue structures in the jawbones. Material and\u0000 methods. Clinical measurements were performed using a questionnaire for\u0000 monitoring the postoperative clinical manifestation, bone measuring calipers\u0000 for measuring horizontal changes of the alveolar ridge and graduated probe\u0000 for measuring vertical dimensional changes, also paraclinical-radiological\u0000 examinations to follow-up bone density.

During the follow up period\u0000 of six months, clinical measurements of post-extraction dimensional changes\u0000 of the alveolar ridges showed minimal horizontal and vertical bone\u0000 resorption with preserved alveolar ridge volume, with an accelerated bone\u0000 regenerative process without special postoperative complications.\u0000 Conclusion. Dentin particulate grafted immediately after extractions should\u0000 be considered as gold standard due to its osteogenetic, osteoinductive and\u0000 osteoconductive effects on bone tissue regeneration.

Due to its simplicity, sliding mechanism is very often used in\u0000 clinical practice for post-extraction space closure, however, the efficiency\u0000 of this method may be reduced due to friction and changes in the properties\u0000 of the materials used in this method. The most commonly used methods of\u0000 sliding mechanics are nickel titanium (NiTi) closed coil spring and elastic\u0000 chain. The aim of this study was to analyze force degradation in the\u0000 application of nickel titanium closed coil springs and elastic chains during\u0000 post-extraction space closure within treatment with fixed orthodontic\u0000 appliances. Material and Methods. The total sample in this study consisted\u0000 of 78 post-extraction spaces in patients who were indicated for extraction\u0000 of first premolars and treatment with fixed orthodontic appliances. Nickel\u0000 titanium closed coil springs and elastic chains were used to close the\u0000 post-extraction spaces.
