“…Many in vitro and clinical studies have evaluated and compared the accuracy of digital and conventional impression techniques and the fit of obtained restorations . Despite the fact that the finish line was subgingival in many clinical studies, the effect of this variable on the fit of restorations was not evaluated . In our study, the position of finish line had no significant effect on marginal gap.…”

Objective This study compared digital and conventional impression techniques regarding impression time, frequency of adjustments, and adaptation of cobalt‐chromium (Co‐Cr) copings with supragingival and subgingival finish lines. Materials and Methods Thirty premolars prepared for single‐unit metal‐ceramic restorations with supragingival and subgingival finish lines (n = 15). Conventional impression and digital scan of prepared teeth were made. Using computer aided design/computer aided manufacturing (CAD/CAM) system the copings were produced by a milling machine from Co‐Cr blocks and internal and marginal discrepancies were measured using silicone replica technique. Data were analyzed using repeated measures ANOVA and Mann‐Whitney test (alpha = .05). Results The impression technique had a significant effect on the magnitude of gap (P < .001). The internal and marginal gaps in the digital technique (49.43 μ and 60.07 μ, respectively) were significantly lower than the values in the conventional method (91.88 μ and 96.96 μ, respectively—P < .001). Finish line positions had no significant effect on the fit and marginal gap of copings (P = .54 and .243, respectively). The mean impression time (19′:27″ in conventional technique and 10′:31″ in digital technique) was significantly shorter (P < .001) and the mean frequency of adjustments (2.2 times for conventional and 1.3 times for digital technique) was significantly lower in the digital technique (P < .001). The gingival biotype (thick or thin) had no significant effect on marginal and internal fit (P = .052 and .319, respectively). Conclusion The digital technique was superior in terms of fit, impression time, and frequency of adjustments. Finish line positions had no significant effect on the fit of copings. Clinical Significance Using intraoral scanner promotes the fits of restorations in supragingival and subgingival finish lines.

“…It has been observed that visual assessment, which is a simple method, is not reliable as clinical experience is an important issue and thin biotype cannot always be identified correctly (12,17). Furthermore, small changes cannot be detected correctly by the measurements performed by ultrasonographic devices, which yield more reliable and repeatable assessments (18,19). It is observed that cone beam computed tomography provides the closest results to reality, but is not preferred owing to the potential side effects of radiation in routine clinical practice (20).…”

Objective: The aim of the present study is to evaluate the relationship of gingival thickness and width of keratinized gingiva with different malocclusion groups and amount of crowding. Methods:A total of 181 periodontally healthy subjects were enrolled in the present study. The study participants were divided into three malocclusion groups: Angle Class I, Angle Class II, and Angle Class III. Each group was divided into subgroups according to the amount of dental crowding, namely mild, moderate, and severe. The width of keratinized gingiva was calculated as the distance between mucogingival junction and free gingival margin, whereas gingival thickness was determined by a transgingival probing technique.Results: Tooth numbers 13 and 23 were observed to have thin gingival biotype. The width of keratinized gingiva for tooth numbers 13 and 23 was narrower in the severe crowding group than in the moderate and mild crowding groups. The relationship of gingival thickness and width of keratinized gingiva with Angle classification was not found to be significant. Conclusion:Although it is thought that there is a relationship between gingival thickness, width of keratinized gingiva, and Angle classification with regard to malaligned teeth, this cross-sectional evaluation of 181 patients failed to show a significant relationship.

Once upon a time, repair and damage control were the expected outcomes of periodontal therapy. However, recent advancements have led to the shift in ideology with regeneration and replacement of what is lost as the ultimate goal of the therapy. Although regeneration is possible and predictable, there are many factors which restrain it from being achievable. The following article addresses such critical issues which are a hindrance in accomplishment of the goal long lasting and stable periodontal tissue regeneration.
