7. Intraoral gothic arc registration technique in the field of total prosthesis and partial prosthesis with considerably reduced dentition

8. Classic/traditional centric records based on neuramuscular self-centering of the condyles in relaxed patients first step is patient relaxation all tooth contacts must be suspended temporarily dental reflex arc? ?? neuromuscular reflex ?? ?? ant. guidance? ??, posterior structure? ?? ??? ??

9. Disagreement on suitable registration material design of the anterior jig necessity supportive manipulative measures during the self-centering process patient position

10. supportive manipulative measures during the self-centering process forced guidance based on radiographic image only provide information on the lateral joint gap maximum posterior position ? ???? ??? registration? ?? ? ?? current theory more anterior position is based on histologic data revealing variations in the quality and quantity of cartilaginous structures in the joint region

24. Centric Interocclusal Record with Metal Foil Template tinfoil carrier template classic alternative to wax plate registration high degree of thermal stability be made thinner error is reduced proportionately as the record grows thinner facilitating use in connection with arbitrary hinge axis localization single registration procedure? ??? ??? adaptation ??

33. Transparent self-hardening reduced shrinkage, distortion on the cast avoidance of damage to the cast surface improved patient adaptation reduction of the opening angle occlusal stop position predetermined through the transparent plate material simplified production technique and no light polymerization

34. Forming the blank on the cast incisal opening setting of 3mm articulator turned over to create tongue room 2 additional supports are attached in the canine and premolar region
