AB  - Objectives: The aim of this study was to evaluate soft tissue development at concave circular macro-grooved titanium abutments in healed sites. Material and methods: In a split-mouth pilot study 10 patients received two implants each at healed posterior sites in contralateral maxillary or mandibular jaw quadrants. Either circular macro-grooved concave study abutments or conventional convex control abutments were immediately provisionalized and received permanent crowns 3 months postimplantation. Marginal bone level, papilla index, modified plaque and bleeding index were recorded. The esthetic outcome was evaluated with standardized perpendicular pictures according to the Pink Esthetic Score (PES). Statistical analysis included the description of all variables by mean value, standard deviation and range. PES values were compared using the Wilcoxon signed rank test for paired data. Results: Cumulative survival rate for all 20 implants was 100%. At the 1-year follow up, there was no statistical significant difference of marginal bone levels between sites restored with the study (-0.11 +/- 0.77 mm) vs. the control (-0.34 +/- 0.53 mm) abutments (P>0.05). Esthetic evaluation (PES) revealed statistically significant differences in scores between the study group [study abutment group] (7.2 +/- 2.82, 8 +/- 1.89) and the control group [control abutment group] (9.5 +/- 1.58, 10.5 +/- 1.72) at the time of prosthetic delivery and the 1-year follow-up. Whereas PES scores for mesial papilla at control sites at the 1-year follow-up demonstrated statistically significant higher values, both soft tissue level and soft tissue contour at control sites revealed statistically significantly higher PES values (P lt 0.05) at time of prosthetic delivery and at 1-year follow-up when compared with study sites. Conclusions: Concave macro-grooved abutments in healed posterior maxillary and mandibular sites did not exhibit a superior soft tissue development compared with standard convex abutments.

AB  - Objectives: A new method is introduced for the esthetic evaluation of the periimplant mucogingival complex through collection of standardized oral photographs and computer-assisted measurement of reproducible data. Using this method, different soft tissue and crown parameters in the dentogingival complex can be measured and the esthetic outcome monitored. Material and methods: A photographic device for standardized oral photography and a standard protocol for the esthetic evaluation of the crown-mucogingival complex is presented, comprising six soft tissue parameters: (1) mesial and (2) distal papilla areas, (3) mesial and (4) distal papilla heights, (5) soft tissue-crown perimeter, and (6) gingival recession. In order to demonstrate the reproducibility of standardized oral photographs and the accuracy of the measurement of the six parameters, the data obtained in each of two such standardized clinical photographs, taken at 10-14 days intervals, of the anterior maxillary region from 10 patients with no apparent dental disease were compared. For the statistical analysis of the reproducibility of these dependent data the 95% confidence interval and the coefficients of variation were calculated from measurement means and ranges of each of the above parameters, pooled from all 10 patients. Results: Statistical analysis revealed high reproducibility with no significant differences between the range of mean values of all six parameter measurements on the first and second standardized oral photograph of the same patient, respectively. Conclusion: Gingivomorphometry on standardized oral photographs can be considered to be an accurate and reproducible method for the evaluation and measurement of different dentogingival and periimplant parameters.

AB  - Objective: A combination of platelet-rich plasma (PRP), bovine porous bone mineral (BPBM) and guided tissue regeneration (GTR) has been shown to be effective as regenerative treatment for intrabony periodontal defects. The purpose of this study was to evaluate the effectiveness of PRP, BPBM and GTR used in combination as regenerative treatment for grade II molar furcation defects in humans. Material and methods: Using a split-mouth design, a total of 52 grade II mandibular molar furcation defects were treated either with PRP/BPBM/GTR (experimental group, n =26) or with an open flap debridement (control group, n =26). The primary outcomes evaluated in this study included changes in pocket depth, attachment level and re-entry bone levels (horizontal and vertical) between baseline and 6 months postoperatively. Results: The results showed that the experimental group presented with significantly greater pocket reduction (4.07+/-0.33 mm for experimental and 2.49+/-0.38 mm for control sites), gain in clinical attachment (3.29 +/- 0.42 mm for experimental and 1.68+/-0.31 mm for control sites), vertical defect fill (2.56+/- 0.36 mm for experimental and -0.19+/-0.02 for control sites) and horizontal defect fill (2.28+/-0.33 mm for experimental and 0.08+/-0.02 mm for control sites) than the control group. Conclusions: It was concluded that the PRP/BPBM/GTR combined technique is an effective modality of regenerative treatment for mandibular grade II furcation defects. Further studies are necessary to elucidate the role played by each component of the combined therapy in achieving these results.
