Consecutive Case Series of Healed Single-Molar Sites Immediately Restored with Wide-Diameter Implants: A 1-Year Evaluation

الملخص EN

Introduction.

To evaluate outcomes of wide-diameter (6 mm) implants immediately provisionalized with cement-retained single crowns in posterior molar sites.

Materials and Methods.

Forty-eight consecutive patients received a total of 53 moderately rough-surface, 6 mm diameter implants in healed sites.

All implants were immediately provisionalized with a cement-retained provisional crown.

Final prosthesis with cement-retained porcelain fused to metal crowns was delivered 3–6 months later.

Patients were followed up for 1 year.

Outcome measures were implant failures and success rate, complications, marginal bone levels, bone level changes, papilla index, bleeding on probing, and inflammation.

Results.

One patient was lost to follow-up.

At one year, the implant survival and success rate were 98.1%.

The mean marginal bone loss after 1 year was − 0.17 ± 1.84 mm.

Ideal papilla score was recorded at 83.8% of the sites.

More than 95.6% of the sites showed no bleeding or inflammation.

No procedure-related or device-related adverse events were reported.

Conclusion.

Wide-diameter (6 mm) implants can safely and successfully replace single posterior molars.

Longer follow-up studies are necessary to evaluate the long-term success of these implants.
