Summary

Oxidized titanium implants show high success rates in jaw reconstruction. This study found only a 1.5% failure rate in 200 implants used in bone reconstructive procedures.

Biomaterials Science

Background:

Rehabilitation with implant-supported bridges often necessitates bone reconstructive procedures for insufficient bone volumes.
Previous studies indicate higher failure rates for turned titanium and bone grafts compared to non-grafted patients.
The clinical performance of oxidized titanium implants in bone reconstruction remains largely unknown.

Purpose of the Study:

To analyze the survival and stability of oxidized titanium implants.
To evaluate implants placed in patients undergoing reconstructive jaw surgery.
To assess clinical outcomes at a single institution.

Main Methods:

Two hundred oxidized titanium implants were placed in 47 patients undergoing six different reconstructive procedures.

Implant stability was assessed using resonance frequency analysis and manual checks.

Radiographs evaluated marginal bone levels after a minimum of 12 months of loading, with a mean follow-up of 30 months.

Main Results:

199 out of 200 implants (99.5%) were osseointegrated at abutment surgery.
Two additional implants were unstable at the 12-month postloading follow-up.
A total of three implants (1.5%) were classified as unsuccessful.

Conclusions:

Clinical experience with 200 consecutive oxidized implants in various reconstruction situations demonstrates a successful outcome.
The study reports a low failure rate of 1.5% over a mean follow-up period of 30 months.
Oxidized titanium implants are a viable option for patients requiring reconstructive jaw surgery.
