Use of Narrow Diameter Implants in the Posterior Jaw

Implant Dentistry Volume 24, Number 3, 2015

PubMed electronic search from January 1990 to March 2014 were included in this paper.

Total of seventeen studies with a total of 1644 implants met the inclusion criteria. The mean survival rate of 98.6% was reported. The inclusion criteria:

  • Implant diameter between 2.9 and 3.5 mm
  • Restoration is fixed
  • Narrow implants in bounded saddles
  • Narrow implants in premolar – molar sites
  • Upper or lower jaw
  • Review articles with follow-up duration of at least 12 months after loading
  • Studies dealing with simultaneous bone augmentation

Conclusion: Short-term clinical data suggests that NDIs may serve in the posterior jaw as an alternative to standard diameter implants.

Must evaluate the patient for risk factors such as:

  • Occlusion and parafunction
  • Bone quality
  • Vertical bone height
  • Restoration emergence profile
  • Medical history and smoking
