PROSTHETIC CONSIDERATION
FOR IMPLANT TREATMENT
REVIEW NOTE

, PROSTHETIC CONSIDERATION FOR IMPLANT TREATMENT
❖ The anticipated load on the implant is affected by its position in the arch. The
more posterior the implant, the higher the anticipatory load. A tooth located
most posteriorly→receives at least twice the load.
❖ Larger diameter implants→stronger prosthetics & are less likely to fracture.
Advantages: -) Enlarged masseter/temporalis muscles.
-) History of broken teeth & crowns, distal-most tooth
in arch & opposing other implants.
-) Patient unwilling to wear occlusal guard (protects
dentition & prosthesis against excessive forces & destructive wear
habits).
❖ Narrow diameter implants→reliable approach to compromised space
(<7mm)→can be mesiodistal i.e., due to adjacent teeth or
implants/buccolingually i.e., the inadequate volume of the alveolar ridge.
This implant is best reserved in low expected loads (incisors of both jaws).
Limitation: more fragile.
1. NUMBER OF IMPLANTS:
• One tooth requires 7mm mesiodistal space, 2 teeth->14mm & 3 teeth->
21mm.
• Two implants with a 3-unit fixed dental prosthesis (FDP)proven to be
quite reliable.
• Gold alloy porcelain fused to metal (PFM) & zirconia-based FDP have
good records but are not perfect.
