Area of Science:

  • Dentistry
  • Oral Surgery
  • Biomaterials Science

Background:

  • Conventional submerged and non-submerged implant placement protocols, established in the mid-20th century, demonstrate comparable success rates.
  • Both conventional protocols result in similar crestal peri-implant bone loss (0.5–1.5 mm) post-loading.
  • Recent advancements include single-stage submerged implant placement with immediate healing abutments, showing positive short-term results.

Purpose of the Study:

  • To evaluate the efficacy of a novel supracrestal implant collar positioning technique for submerged implants in posterior sectors.
  • To assess the impact of this technique on the second surgical stage and prosthetic restoration.
  • To determine the effect of supracrestal positioning on limiting crestal bone loss around dental implants.

Main Methods:

Related Experiment Videos

  • Review of existing literature on conventional and single-stage implant placement protocols.
  • Analysis of studies reporting on supracrestal apical-coronal positioning of submerged implant collars.
  • Comparison of outcomes related to surgical phase facilitation, prosthetic restoration, and crestal bone levels.

Main Results:

  • Conventional and single-stage submerged implant protocols exhibit satisfactory success rates.
  • Supracrestal positioning of submerged implant collars in posterior regions simplifies the second surgical stage.
  • This positioning technique appears to effectively limit crestal bone loss, enhancing long-term implant stability.

Conclusions:

  • The supracrestal positioning of submerged implant collars represents a promising advancement in dental implantology.
  • This technique offers benefits in terms of surgical and prosthetic procedures.
  • Further research is warranted to confirm long-term efficacy in preserving crestal bone levels.
