One-stage versus two-stage technique using two splinted extra-short implants: A multicentric split-mouth study with a...

Area of Science:

• Dental Implantology
• Oral Surgery
• Prosthodontics

Background:

• Extra-short implants (≤6.5mm) are utilized in limited bone height situations.
• The choice between one-stage and two-stage surgical techniques can impact clinical outcomes.
• Comparative data on these techniques specifically for extra-short implants is limited.

Purpose of the Study:

• To compare clinical outcomes of extra-short implants placed using one-stage versus two-stage techniques.
• To evaluate implant survival, success rates, and prosthodontic complications.
• To assess secondary parameters including implant stability, marginal bone level, and periodontal health.

Main Methods:

• A split-mouth multicenter study design was employed.
• Implants were randomly assigned to either a one-stage or two-stage healing protocol.
• Clinical outcomes and measurements (ISQ, MBL, PI, PD, BoP) were assessed at multiple time points up to 12 months.

Main Results:

• Implant cumulative survival and success rates were 100% at 12 months for both techniques.
• No statistically significant differences were observed between the one-stage and two-stage groups for any primary or secondary outcomes.
• Implant stability quotient (ISQ) and marginal bone loss (MBL) remained comparable between groups throughout the study period.

Conclusions:

• The one-stage technique provides optimal clinical outcomes for extra-short implants.
• Outcomes using the one-stage technique are comparable to the traditional two-stage approach.
• This suggests the one-stage technique is a viable option for extra-short implants in the short term.
