Evaluation of Extraction Site Dimensions and Density Using Computed Tomography Treated With Different Graft Materials: A Preliminary Study

Purpose:The preliminary human study was designed to evaluate extraction site changes using CT after socket preservation (SP) with different materials.Materials and Methods:Fifty-two sockets from 17 Turkish individuals (8 women and 9 men; mean age 44.70 9.99 years) localized at the maxillary anterior area were treated with demineralized bone matrix + collagen membrane (CM) (N = 14), hydroxyapatite bone substitute (HBS) + CM (N = 14), CM (N = 13), or left empty (N = 11). CT scans were taken 10 and 120 days after the procedure. Horizontal and vertical socket dimensions and Hounsfield unit (HU) values were evaluated.Results:First 3 groups showed a significant horizontal decrease from day 10 to 120. No significant change was detected in vertical socket dimension. For both horizontal and vertical, no intergroup difference was detected at days 10 and 120. At days 10 and 120, HU values in HBS + CM group were significantly higher compared with others. Apical and coronal HU values were not different at any period.Conclusion:Even if it did not provide better socket dimensions, HBS + CM treatment brought higher tissue density and thus, can be recommended to increase the bone quality and implant success after SP in upper anterior area

Treatment of gingival recession: Comparison of two techniques of subepithelial connective tissue graft

Background: The increasing interest in esthetics and the subsequent need to solve related problems such as hypersensitivity and root caries have favored the development of many surgical procedures that permit the coverage of exposed roots. This clinical study was conducted to examine the coverage of gingival recession defects, where two different subepithelial connective tissue graft (SCTG) techniques (Langer and Langer and modified tunnel) were used

The effects of vertically coronally advanced flap and free gingival graft techniques on shallow vestibule: a randomized comparative prospective trial

Objectives: The present study aimed to compare the influence of vertically coronally advanced flap (V-CAF) and free gingival graft (FGG) techniques on shallow vestibule depth (VD). Materials and methods: Parallel-arm randomized clinical trial was conducted on 38 sites treated with either FGG or V-CAF. Periodontal variables (VD, recession depth and width, probing depth, clinical attachment level, keratinized tissue height (KTH), and tissue thickness (TT)), clinician- and patient-based subjective variables were assessed. Results: All periodontal variables showed significant improvements in both groups at all follow-up intervals compared to baseline (p < 0.05). Both groups increased VD compared to baseline. RC and CRC were similar after treatment for both techniques. FGG provided a greater increase in KTH (p < 0.001) and VD (VD1, p = 0.02 and VD2, p < 0.001) while V-CAF exhibited more TT gain (p = 0.002). Except overall tissue appearance that was better in V-CAF (p < 0.001), no inter-group significant difference existed in patient-based variables. Conclusions: Both techniques were significantly effective in VD increasing. While both techniques were equally successful in RC, V-CAF provided higher TT gain and better tissue appearance. V-CAF can be chosen instead of FGG in the treatment of recessions with shallow VD. Clinical relevance: It can be recommended to prefer V-CAF instead of FGG in the treatment of shallow vestibule.
