IMMEDIATE IMPLANT PLACEMENT INTO EXTRACTION SITES. SURGICAL AND RESTORATIVE ADVANTAGES

Question 1

WHAT IS IMMEDIATE IMPLANT PLACEMENT?

Answer 1

Immediate implant placement is when an implant is placed at the same time as the natural tooth is extracted .

• Implant placement in fresh sockets was first reported by Schulte and Heimke in 1976, termed ‘immediate implant’.
• Over the years there have been many studies reporting high survival rates.
• The expert recommendations published for single implant placement following the Foundation for Oral Rehabilitation (FOR),were that careful patient selection , proper treatment planning , and precise implant placement were necessary to gain predictable and aesthetic results .

Question 2

Patient evaluation

Answer 2

• The first step in determining whether immediate implant placement is a reasonable clinical choice is the evaluation of the potential implant site.
• All the systems provide criteria for evaluating the bony morphology for immediate implant placement.

Question 3

The ideal extraction site for immidiate implant placement

Answer 3

• The ideal extraction site for immediate implant placement is one with little or no periodontal bone loss on the tooth that is to be extracted, such as a tooth being extracted due to endodontic involvement, root fracture, root resorption, periapical pathology, root perforation, or unfavourable crown-to-root ratio
• Most reasearch recommend at least 3 to 5 mm of bone beyond the apex and a bony length of 10 mm or greater for stability when placing immediate implants

Question 4

CONTRAINDICATIONS

There is general consensus that suitable sites for immediate implant placement do not include those with:

Answer 4

• severe labial
• circumferential bone defects or
• bony defects with two or three missing walls

Question 5

WHEN BONE GRAPFT IS REQUIRED?

Answer 5

• If jawbone isn’t thick enough or is too soft , you may need bone grafting before you can have dental implant surgery
