a simplified guide for arranging 30 degrees pilkington turner posterior denture teeth in a balanced occlusion a simple technique is presented for achieving balanced occlusion when setting 30 degrees pilkingtonturner teeth this technique involves the rotation of the mandibular posterior teeth around three axes the vertical axis to align the grooves and embrasures with the lateral path of the movement of the cusps the mesiodistal axis to achieve the curve of wilson and the buccolingual axis resulting in the curve of spee cultivation of methanogens under lowhydrogen conditions by using the coculture method we previously reported the isolation of novel methanogens by using a new cultivation method referred to as the coculture method here we extended our coculture method to various anaerobic environmental samples as a result we successfully cultivated some uncharacterized methanogens in coculture enrichments and eventually isolated a new methanogen within the order methanomicrobiales
