To achieve optimum periodontal health, FPD finish line should be  Supragingiva whenever possible, at least 0.5 away from free gingiva to allow self cleaning

30. Margin design dos NOT provide adequate bulk for restorative material  Feather edge 31. When 2 missing adjacent teeth are replaced with FPD, connectors should be  Rigid at both retainers, and non rigid between pontics 32. Path of insertion for an anterior ¾ crown  Parallel to incisal ½ of the labial surface 33. Functional cusp bevel for a full or partial veneer casting  Provides space for material of adequate thickness in area of heavy occlusal contact 34. All ceramic restorations require this marginal finish line  Wide 90 degree shoulder 35. Advantage of metal ceramic crown  Superior esthetics compared to all metal crown 36. Advantage of supra gingival margin  Can be easily finished without soft tissue trauma  Impression easy, less potential soft tissue damage  Evaluations on resto easy at time of placement and recall  Self cleansing 37. NOT guideline for proper tooth structure conservation  Preparation of teeth with maximum practical convergence between axial walls 38. A non rigid connector is comprise of  Key and keyway 39. To achieve optimum casting results in the metalceramic technique, use  Phosphate bonded investment 40. NOT reason for cemented FPD to be loose  Deformation of metal casting on the abutment 41. Contraindication for porcelain veneers  Severe over spreading for teeth 42. Strength pf solder joint is proportional to  Thickness? 43. Force acting through the FPD on to abutment should be directed to  Parallel to long axes of tooth  Decrease buccolingual width

44. Definition of quenching  Rapidly cooling metal from high to low temperature 45. To achieve optimum margin for a casting that can easily be burnished to improve fit  Supra gingival 46. Margin design for lingual prep for metal ceramic crown  Chamfer 47. Fracture/failure in metal ceramic restoration  Porcelain metal interface 48. According to ADA classification for alloy systems used for metal ceramic restorations, noble alloys  Have a noble metal content of >25% 49. Quality of preparation that prevents the restoration from dislodging to forces parallel to path of placement  Retention 50. Does NOT increase retention  Increase preparation smoothness 51. Distobuccal cusp of a permanent mandibular 1st molar occludes where  Central fossa of maxillary 1st molar 52. Most important step in RPD construction  Clinical examination  Survey  Design  Tooth altercation 53. Reciprocal arm of a circumferential clasp  Contact guiding plane approximately 180 degrees around the tooth from its tip  Rigid  At or occlusal to height of contour 54. Linguoplate indicated  Needs stabilization  Need of indirect retainers  High frenal attachment  Bilateral free end case 55. Ligament that gives direct support to the capsule of TMJ  Temporomandibular ligament 56. If both arches need RPD, which one should be constructed 1st  Both constructed at the same time
