Purpose: . This study evaluated the accuracy of implant impression techniques using scan healing abutments compared to conventional techniques. Materials and methods: . A mandibular model with implants at #34, 36, and 46 was used. Experiments were conducted for single implant and 3-unit bridge scenarios. Groups were as follows: Group IOS - Scan healing abutments were scanned with an intraoral scanner. Group Imp - Scan healing abutments were used, and impressions were taken with silicone material, followed by model scanning. Group Sb - Scan bodies were scanned with an intraoral scanner. Group Trans - Impressions were taken with transfer copings, and models were scanned. Each group was scanned 10 times, and deviations in central distance and angulation of analogs were measured. Statistical analyses were performed using ANOVA and post-hoc tests at a 95% confidence level. Results: . For single implants, there were no significant differences in distance deviation (P > .05). Angular deviation values were: IOS (0.24 ± 0.10°), Imp (0.19 ± 0.06°), Sb (0.38 ± 0.05°), and Trans (0.29 ± 0.06°), with Sb showing significantly larger values than IOS and Imp (P < .05). For bridges, distance deviation did not significantly differ (P > .05). Angular deviations were: IOS (0.21 ± 0.08°), Imp (0.21 ± 0.09°), Sb (0.25 ± 0.10°), and Trans (0.46 ± 0.19°), with Trans showing significantly larger values than the others (P < .05). Conclusion . Scan healing abutment techniques showed similar accuracy to traditional methods. They could be a viable alternative for single implant crowns or short-span fixed dental prostheses.

Purpose: To evaluate the efficacy of topical bromfenac combined with intravitreal aflibercept (IVA) injection in the treatment of exudative age-related macular degeneration over a 2-year period. Methods: We retrospectively studied 43 patients (43 eyes) with exudative age-related macular degeneration. Patients were included if they received IVA injections under an as-needed protocol and had > 2 years of follow-up. Among the 43 eyes, 25 received only IVA (IVA group), whereas 18 received a combination of IVA and topical bromfenac (bromfenac group). The primary outcome measure was the total number of IVA injections administered over 2 years from the initial injection compared between groups. We also compared changes in best-corrected visual acuity (BCVA) and central retinal thickness (CRT) between groups. Results: The bromfenac group received a significantly lower number of IVA injections over 2 years (7.4 ± 1.0), compared with the IVA group (9.0 ± 1.9) (p < 0.01). Both groups showed improvements in BCVA and CRT after 2 years compared with their baseline values. However, changes in BCVA and CRT at 2 years did not significantly differ between groups (p = 0.786 and p = 0.905, respectively). Conclusions Among patients with exudative age-related macular degeneration, the total number of IVA injections over 2 years was lower in the bromfenac group than in the IVA group. More studies are needed to confirm the efficacy of topical bromfenac in a combined treatment regimen.

Purpose: To evaluate the efficacy of topical bromfenac in treating central serous chorioretinopathy (CSC) over a 1-year period. Methods: A retrospective analysis was conducted on 57 patients (57 eyes) with CSC followed for > 1 year. Patients were divided into two groups: those treated with bromfenac eye drops twice daily (29 eyes) and a control group (28 eyes). Best-corrected visual acuity (BCVA), central macular thickness (CMT), and subretinal fluid (SRF) height were measured and compared between the two groups as was the proportion of chronic cases. Results: Significant improvements in CMT and SRF height were noted in both groups over the follow-up period. The bromfenac group demonstrated significantly lower CMT at 6, 9, and 12 months (p = 0.045, 0.042, and 0.023, respectively) and lower SRF height (p = 0.037, 0.048, and 0.046, respectively) compared to the control group. The proportion of chronic cases was significantly lower in the bromfenac group (17.2%) compared to the control group (42.9%, p = 0.035). Conclusions Topical bromfenac reduced the rate of progression to chronic CSC and showed significant anatomical improvements after 6 months, suggesting its potential as an effective treatment option.

In fixed prosthodontic treatment of the maxillary anterior region, where high esthetics are required, it is crucial not only to achieve a successful prosthesis but also to form symmetrical and natural gingiva. To achieve esthetic gingiva, it is necessary to adjust the subgingival contour of the temporary prosthesis or to modify the base of pontic. However, during the transition from temporary to definitive prosthesis, the conventional method of removing the temporary prosthesis and taking an impression after gingival retraction often fails to accurately reproduce the gingival profile. In such cases, the gingiva is arbitrarily trimmed on the model to fabricate the definitive prosthesis, which reduces the predictability of esthetic treatment outcomes. This case report introduces methods to transfer the subgingival contour and the pontic base formed with the temporary prosthesis to the final model and definitive prosthesis through two cases.

Advancements in CAD-CAM technology have allowed for a variety of options in implant-supported fixed prosthesis restorations for completely edentulous patients. For patients with severe alveolar bone resorption, zirconia prosthetic restorations that include the gingival portion, such as implant-supported hybrid dentures, are possible, as well as monolithic zirconia prosthetic restorations in the form of crowns. The integration of digital technology in fixed prosthetic restoration using implants enables predictable treatment through diagnosis and virtual surgery by integrating the patient’s clinical and radiological information. In this case, the utilization of digital software allowed for the establishment of implants in appropriate positions, considering both the remaining alveolar bone and the final prosthesis. By designing both the maxillary removable prosthesis and the mandibular fixed prosthesis simultaneously in CAD software, bilateral balanced occlusion could be easily achieved. Furthermore, maintaining the initial interocclusal relationship from provisional restorations to final prostheses allowed for convenient transition while ensuring functional and aesthetic satisfaction.

Class II malocclusions present with a different occlusal pattern to patients with Class I malocclusions, characterized by a large overjet and overbite in the anterior region, resulting in habitual mandibular protrusion during speech or mastication. When rehabilitating Class II patients, it is important to consider lateral and anterior guidance, to ensure balanced posterior guidance during protrusive movements before anterior contact, and to establish freedom in the intercuspal position. In this case, digital tools were used for the full-mouth rehabilitation of a skeletal class II patient. A virtual patient was created using facial scan data, digital facebow transfer and jaw motion tracking. Provisional restorations were fabricated based on the virtual patient. After identifying occlusal interference during anterior movement with the first provisional, the virtual patient was updated and the occlusal design was refined. For the final restorations, the virtual patient was updated again to reflect the functionally and esthetically satisfactory provisional restorations and their adapted occlusion. This digital approach facilitated accurate replication of the dynamic occlusal relationships, resulting in functionally and esthetically successful outcomes.
