Summary: | Statement of Problem: The long-term success of a dental implant relies on
implant osseointegration into native and viable bone, implant placement in
an ideal position, and optimal hard and soft tissue contour. This requires the
presence of sufficient alveolar bone volume, good alveolar ridge (Practically
with no sign of atrophy) and good surgical technique.
Objectives: The aim of this randomized controlled clinical study was to
evaluate morphometric changes after different alveolar ridge preservation
procedures.
Materials and Methods: In this study, 33 patients who had single-rooted
premolar, which needed to be extracted, were recruited. Patients were randomly
divided into 3 groups and after tooth extraction the following treatments
were administered: in group A: NanoBone and a collagen membrane;
in group B: NanoBone and Stypro; and in group C: natural healing. The
following clinical parameters were evaluated at baseline and 6 months after
the extraction: buccolingual width, midbuccal height (with the use of a custom
made stent) and width of keratinized gingiva. For data analysis, Paired
t-test,one-way ANOVA and Tukey’s tests were used.
Results: The average reduction in the buccolingual width, midbuccal height
and keratinized gingiva was as follows: group A: 1.18±0.6, 0.64±0.92 and
3.45±1.75 mm; group B: 2.18±0.75, 0.73±0.78 and 4.73±0.9 mm; and group
C: 1±0.89, 2.36±1.21 and 5±0.63 mm, respectively. Moreover, a significantly
reduced resorption was found in both the buccolingual width and the
width of keratinized gingiva in group A as compared to groups B and C
(p<0.05).
Conclusions: This study showed that the use of collagen membrane+Nano
bone (group A) can significantly reduce the horizontal resorption of the
alveolar ridge and keratinized tissue more effectively than stypro+Nano
bone (group B ) and blood clot alone and natural healing (group C). |
