Area of Science:

  • Oral surgery
  • Dental implantology
  • Periodontology

Background:

  • Very narrow alveolar ridges pose challenges for dental implant placement.
  • Bone augmentation techniques are crucial for successful implant rehabilitation in atrophic jaws.

Purpose of the Study:

  • To evaluate the two-stage split-crest technique using ultrasonic bone surgery for dental implants in patients with extremely narrow ridges.
  • To assess soft and hard tissue status and determine the implant success rate.

Main Methods:

  • Nine implants were placed in six patients using the two-stage split-crest technique.
  • Plasma rich in growth factors-Endoret was utilized for tissue regeneration and osseointegration.
  • Clinical evaluations were performed at least 6 months post-implant loading.

Finite Element Analysis Model for Assessing Expansion Patterns from Surgically Assisted Rapid Palatal Expansion

Published on: October 20, 2023

Main Results:

  • Soft tissue parameters (plaque index, bleeding index, probing depth) indicated healthy conditions.
  • Implant success rate was 100% at follow-up (15-22 months post-surgery).
  • Significant bone ridge expansion was achieved, averaging 5.60 mm apically and 7.33 mm occlusally.

Conclusions:

  • The two-stage split-crest technique combined with ultrasonic bone surgery is a safe and predictable method for bone expansion.
  • This technique effectively addresses the challenges of implant placement in very narrow ridges.
  • High implant success rates and favorable tissue conditions support its clinical application.
