A typodont mandibular molar was prepared. From each workflow, 20 zirconia crown copings were milled from a single scan. Ten zirconia crown copings were assigned randomly from each workflow to be finished and polished. Finishing and polishing in the hybrid workflow were done directly on the typodont, representing the control die. There were four groups in this study: No-die-Before (full-digital without finishing and polishing), No-die-After (hybrid without finishing and polishing), Die-based-Before (full-digital with finishing and polishing), and Die-based-After (hybrid with finishing and polishing). The typodont tooth was divided into eight zones for systematic measurement. All groups were evaluated using a digital optical microscope.Results: The mean values with the standard deviation of No-die-Before, No-die-After, Die-based-Before, and Die-based-After groups were 24.90 ± 23.88, 30.62 ± 32.63, 21.03 ± 16.65, and 18.93 ± 18.27, respectively. The maximum values for the No-die-Before and No-die-After groups were 124 and 131 µm, respectively. All the values in the Die-based-Before and Die-based-After groups were less than the acceptable marginal gap of 75 µm.Conclusions: There was no statistical significance between the two workflows. However, the control die enabled achieving superior accuracy. Without it, the marginal gap might worsen after finishing and polishing in the full-digital workflow.","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144053170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The porcelain and indirect composite resin samples were divided into two subgroups (n = 30). The initial color and roughness values of the samples were measured. A special setup was created to simulate cigarette smoking, where the samples were placed inside and exposed to two different types of cigarette smoke. After exposure, the final color and roughness values of the samples were measured again.Results: After conventional cigarette exposure, porcelain specimens showed color changes of ΔE*ab = 7.404, ΔE00 = 7.502, and indirect composite resin specimens ΔE*ab = 9.708, ΔE00 = 19.501, with significant surface roughness increases in both materials (p < 0.05). After electronic cigarette exposure, porcelain specimens had color changes of ΔE*ab = 1.390, ΔE00 = 1.317, and indirect composite resin samples ΔE*ab = 2.523, ΔE00 = 2.454. Surface roughness decreased significantly for porcelain (p < 0.05) but increased for composite resin which was not statistically significant (p > 0.05).Conclusion: Conventional cigarette exposure resulted in more significant color changes and surface roughness increases in gingiva-colored materials compared to electronic cigarettes. Indirect composite resins demonstrated lower color stability than porcelains. Patients with gingiva-colored porcelain and composite resin restorations should be informed about color and surface roughness changes due to smoking.","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This design was used to fabricate printed (P-PEEK), milled (M-PEEK), and heat-pressed (HP-PEEK) PEEK abutments (n = 8). The marginal gaps of all abutments were evaluated under a stereomicroscope (15 points on each side, ×40 magnification), before and after thermal cycling (10,000 cycles, 5°C-55°C). Then, all abutments were subjected to a pull-off bond strength test. The marginal gap data were analyzed with a generalized linear model, while the pull-off bond strength data were analyzed with one-way analysis of variance and Tukey tests (α = 0.05).Results: The marginal gaps were affected by the interaction between the fabrication method and aging condition, as well as by the fabrication method and aging condition (p ≤ 0.003). HP-PEEK abutments before thermal cycling had the lowest gap, whereas M-PEEK abutments after thermal cycling mostly had the highest (p ≤ 0.042). Thermal cycling increased the marginal gap of HP-PEEK (p < 0.001). M-PEEK had the lowest and HP-PEEK had the highest pull-off bond strength (p < 0.001). Most of the failures of P-PEEK and M-PEEK abutments were mixed.Conclusions: The tested abutments had marginal gaps below the clinically acceptable threshold of 120 µm, both before and after thermal cycling. HP-PEEK abutments may be more resistant to dislodgment from the Ti-base abutments than P-PEEK and M-PEEK abutments.","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143774695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mesial drift of adjacent teeth may hinder ideal rehabilitation. Uprighting of mesially titled teeth can allow for implant restorations with more ideal contours. Uprighting of mesially titled teeth can be achieved through orthodontic treatment which can be assisted by dental implants for anchorage. This article introduces an osseointegrated implant- supported device called the Implant Supported Distalising Piston (ISDP) to upright two mesially tilted mandibular second molars. Two patients presented to a prosthodontics practice with implants placed several years before seeking prosthodontics treatment. The mandibular second molars were mildly mesially tilted and encroached on the space needed to design implant-supported crowns with ideal contours. CAD-CAM technology was used to design implant-supported zirconia crowns with a distalising piston placed into the distal of the crown to upright a mesially titled molar. The Implant Supported Distalising Piston successfully corrected two mesially titled molars to allow for a more ideal implant restoration.","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the time of extraction, patients were assigned to three groups, Group A (type I socket with ARP), B (type II socket with ARP), and C (type II socket with ARP and membrane). Following flapless extraction, an ovate pontic with ARP was placed. Impressions were taken before extraction, and at 3- and 6-month follow-up visits. Master casts were created to measure dimensional alterations. Descriptive statistical analysis compared changes in linear and volumetric measurements over the follow-up period.Results: After 6 months, Group A showed mean dimensional changes of -1.28 ± 0.75 mm in width, -1.19 ± 0.61 mm in height, and -30.51 ± 17.55 mm3 in volume. Group B had changes of -1.07 ± 0.48 mm in width, -1.12 ± 0.51 mm in height, and -23.36 ± 7.74 mm3 in volume. Group C experienced changes of -1.43 ± 0.41 mm in width, -0.98 ± 0.32 mm in height, and -31.27 ± 9.59 mm3 in volume.Conclusions: Utilization of an ovate pontic provisional restoration in conjunction with ARP minimizes post-extraction ridge alteration and maintains natural morphology, providing a stable prosthetic foundation for fixed restorations, regardless of bone plate presence.","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143711688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
