Abstract :

Context:

Healing process after tooth extraction never results in complete restitution of the original alveolar bone volume due to physiologic resorption. Various methods have been tried in literature for preservation of the extraction socket. This study evaluates the efficacy of Beta-Tricalcium phosphate in type I collagen plug for preservation of mandibular extraction sockets.

Aims and objectives:

Aim of this study is to evaluate the healing of extraction sockets preserved with Beta-Tricalcium phosphate in type I collagen plug clinically and radiographically and to compare them with normal healing sockets.

Settings and Design:

Prospective, randomised controlled clinical trial with split mouth design was selected to avoid individual variations in the healing process.

Methods and Material:

10 systemically healthy adult patients, 22-32 years of age (mean age: 26.6 years), who underwent surgical removal of bilateral impacted third molars in the mandible was selected for the study. One side was grafted with test material and other was left to heal spontaneously as control side. Healing was evaluated clinically and radiographically using CBCT greyscale values.

Statistical analysis used:

Independent samples t-test was used to compare the mean differences in socket dimensions and mean CBCT grey scale values. Non-parametric Mann-Whitney test is used to compare the clinical attachment levels

Results:

Sites grafted with the study material when compared to control side showed

1. Better clinical attachment levels

2. Significant reduction in alveolar crestal bone loss and

3. Better bone quality

Conclusions:

Results obtained showed that there is a significant improvement in quantity and quality of alveolar bone if preserved with Beta-Tricalcium phosphate in type I collagen plug, which is more suitable for future dental implant placement.
