There were many similarities but, crucially, some differences in biomarker levels (IL-1β and sRANKL) and bacterial species between peri-implant and periodontal sites in the same individuals, suggesting similar pathogenic mechanisms.

Objective The aim of this study was to introduce a novel soft tissue thickness measurement method using cone beam computed tomography (CBCT) and to compare the new method with ultrasonic device applications and transgingival probing measurements. Methods Twenty‐five participants (12 female, 13 male, age range, 25‐51 years) were included the study. Soft tissue thickness in lateral incisor, canine, premolar, and molar regions were measured using transgingival probing (group T), ultrasonic device (group U), and CBCT scan measurements (group C). Differences and correlations between groups and agreement between measurement methods were evaluated. Results Soft tissue thickness was significantly lower in group U in premolar region, but was significantly higher in molar region compared with group C and group T (P < .05). There were significant positive correlations in lateral incisor and canine region, between group U and group C, in premolar region between group T and group C, and in molar region between group U and group C, and between group C and group T (P < .05). The highest agreement between measurement methods was evident between group T and group C. Conclusion Soft tissue thickness values in maxilla may differ depending on the measurement method and location of the measurement. Ultrasonic device, transgingival probing, and CBCT measures may not necessarily correlate in all locations. The high agreement between CBCT measurements and transgingival probing may suggest the newly introduced method as a promising technique for soft tissue thickness evaluation. Clinical Significance This study evaluated the relation between different soft tissue thickness measurement methods and demonstrated a novel method which can be used in any part of the mouth. The outcome also suggested that the measurement method and the location might affect the soft tissue thickness value obtained, and therefore might be important in clinical decision making.

Adhesive cementation and intentional replantation were an effective treatment modality for this group of vertically fractured maxillary single-rooted teeth. The clinical periodontal parameters decrease by month 6, and the mobility returned to the physiological limits of natural teeth 12 months after replantation.

Objective: To evaluate the clinical efficacy of xenogeneic acellular dermal matrix (XADM) or connective tissue graft (CTG) combined with modified-coronally advanced flap (M-CAF) in the treatment of multiple gingival recessions. Materials and methods: Twelve participants with bilateral MGRs (multiple gingival recession) (82 gingival recessions) randomly received XADM (test group, 41 teeth) on one side and subepithelial CTG (control group, 41 teeth) on the other side in conjunction with M-CAF in the same session and completed the 18-months study period. Recession depth (RD), recession width (RW), keratinized tissue width (KTW), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, and 6-, 18-months postoperatively.Results: PD was significantly higher in the test group at 18-months (P < .05). PD in the test group was also significantly higher at 6-and 18-months compared to baseline (P < .05). RD and RW were significantly lower at 6-and 18-months compared to baseline in both groups (P < .05) and both parameters were significantly higher in the test group at 18-months (P < .05). Percentage of teeth with complete root coverage in the test and control groups were similar at 6-months (78% and 70.7%, respectively) and at 18-months (both 87.8%) (P > .05). Conclusion:Within the limits of the study, M-CAF combined with XADM or CTG seems to be similarly effective in RD reduction of class I and II MGRs at least in the short term. Soft tissue shrinkage and increase in PD may be observed with XADM, while; CTG seems to provide stable clinical outcomes for 18-months follow-up.Clinical significance: Even though the CTG and XADM in conjunction with M-CAF may provide similar RD reduction in class I and II multiple gingival recessions in the short term. CTGs may be superior in terms of soft tissue shrinkage and PD values.

The present findings indicate that smokers have a higher risk of inflammatory peri-implant diseases. Therefore, more frequent recalls may be recommended in smokers with dental implants.

AimTo compare clinical outcomes of ‘extra‐short' and regular bone level implants in the posterior maxilla for 12 months after loading.Materials and MethodsTwenty‐three systemically healthy, non‐smoking patients received 30 extra‐short, 24 regular bone level implants. Acrylic stents were fabricated for each patient for correct implant positioning. Implant lengths were 4–6 mm in the test, 8/10 mm in the control group. Radiographic evaluation was performed at baseline, 6, and 12 months after loading. Crestal bone level (CBL), CBL change (CBLC), true crown length (TCL), implant/crown ratio (ICR) and residual bone height (RBH) below maxillary sinus floor were calculated digitally. Data were tested statistically.ResultsResidual bone height was significantly lower, and TCL and ICR were higher in the test than the control group (P < 0.0001). CBL measurements at baseline were 0.19 ± 0.18 mm and 0.31 ± 0.37 mm and at 12 months, 0.24 ± 0.24 mm and 0.41 ± 0.31 mm, respectively in the test and control groups. CBL values at 12 months were significantly lower in the test than the control group (P < 0.05). CBLCs were similar at all times (P > 0.05). No correlation was found between the CBLC and implant/prosthetic parameters.ConclusionExtra‐short and regular implants might provide similar clinical outcomes in prosthetic rehabilitation of atrophic maxilla, during 12 months follow‐up.
