Clinical evaluation of immediate implants using different types of bone augmentation materials

The immediate placement of implants into fresh extraction socket has proven to be a safe and predictable procedure. However, there is lack of scientific evidence regarding the healing pattern and osseointegration associated with immediate implants especially with different grafting materials.

A total of 30 patients male or female, with a mean age of 23.1 years ± 6.0 in the age group of 18-38 years, each having at least one tooth indicated for extraction (either maxillary or mandibular anterior teeth) were selected and randomly divided in to two groups. 30 Implants (Xive(®) friadent, Germany) were placed into fresh extraction sockets during this study. Two types of graft materials namely Dembone(®) (freeze-dried bone allograft) for group A and G-Bone(®) (modified hydroxyapatite) for group B were used. After implant placement all implants were evaluated clinically and radiographically at baseline, 3 months, 6 months, 9 months and 12 months. All clinical and radiographic parameters were subjected to statistical analysis. Intragroup comparisons were made with paired 't' test and intergroup comparisons with unpaired 't' test (P > 0.05 NS, ≤0.05 S, ≤0.01 HS).

During the 1-year interval, no implant was lost and the mean bone level at the implants was maintained or even improved.

Immediate restoration of single tooth implants placed in fresh extraction sockets could be considered a valuable option to replace a missing tooth. The graft materials used in both groups have been found to be equally effective.
