Periodontal-Restorative Interrelationships

Question 1

What is a prerequisite for successful restorative treatment?

Answer 1

Perio health

Question 2

Why do you do perio treatment before restorative treatment?

Answer 2

Stable gingival margins before tooth prep
No/less bleeding
Adequate tooth structure available
Resolution of inflammation may change too position, relations, and soft tissue position
Resolution of inflammation eliminates risk of CAL
Ideal perio conditions help maintain health
Ideal perio conditions allow maximal benefits from restorative therapy (esthetics)

Question 3

Gingival shrinkage

Answer 3

If the gingiva becomes healthy, it will shrink, which will move the gingival margin

Question 4

What are the different phases of the Treatment sequence?

Answer 4

Etiologic phase
Pre-prosthetic phase
Restoration design
Pre-implant surgery
Post-prosthetic surgery
Maintenance

Question 5

Etiologic phase of treatment

Answer 5

Correct faulty restorations - ie overhangs and biological width violations

Question 6

Pre-prosthetic surgery procedures

Answer 6

Crown lengthening
Mucogingival procedures
Ridge preservations procedures
Ridge augmentation procedures

Question 7

What should we keep in mind with restoration design?

Answer 7

Ease of home care

Direct effects on tissue

Question 8

Pre-implant surgery procedures

Answer 8

Ridge preservation
Ridge augmentation
Sinus elevation

Question 9

Post-prosthetic surgery procedures

Answer 9

Correction of tissue deformities
