26. Removable provisional may be unstable solution because :

27. Implant placement in anterior single tooth is predictable treatment outcomes if:

Patient with high smile line

The sites without hard and soft tissue deficiency

Patient motivation

D.Patient with high smile line and The sites without hard and soft tissue deficiency

28. Dental implant therapy in the anterior is a complex procedure, which base on a comprehensive preoperative evaluation. An optimal esthetic result depends on

29. Single tooth implant in the anterior area is a surgical risk procedure if:

Buccal bone deficiencies

Soft tissue deficiencies

Distance between the proximal bone and CEJ of the adjacent teeth > 2mm

Buccal cortical bone plate < 1mm

All are correct

30. The provisional fixed restoration plays a major role in esthetic outcome because:

It can be modified to create emergence profile

It is easy to fabricate

The quality of bone at the implant site.

46. Pain after implant surgery is normal physiologic response to tissue damage. Pain intensity comes to the peak after:

47. The statements below are true, Except:

The design of the restoration is a key factor for implant selection.

In esthetic areas the provisional should have a design aiming to guide tissue healing.

A standard implant requires 5mm mesiodistal distance, 10mm bone height, and 5mm bone width.

Wide implants are preferred for molars, and when high occlusal loading is expected.

Long implants (>10mm) are indicated when poor primary stability is expected with standard implants

48. The statements below are true, Except:

Cemented restorations are advisable used for the implant shoulder located deep under the mucosa in esthetic areas

Implant-supported FPD is the dominant strategy for partially edentulous patients.
