To manage the complexities arising from delayed presentation, the prosthodontic team developed a highly tailored treatment plan to meet the patient's unique clinical needs, which included fabrication of customized healing abutments, an implant indexing device, and a definitive removable implant-tooth-supported occlusal overlay prosthesis, which incorporated an atypical increase in the vertical dimension of occlusion (VDO) of 12 mm.

Two minor technical complications occurred (denture tooth debond events) and one minor biological complication (localized peri-implant mucositis) within the follow-up period.

The specimens underwent repeated applications of the cariostatic agents (3 min, repeated six times) and were evaluated for surface roughness (∆Ra) by profilometry and for color change using a digital spectrophotometer, with analysis based on the CIEDE2000 system (∆E<sub>00</sub>). Data were analyzed using two-way analysis of variance (ANOVA), followed by one-way ANOVA or Kruskal-Wallis tests with appropriate post hoc comparisons and Bonferroni correction (α = 0.05).</p><p><strong>Results: </strong>A statistically significant interaction was observed between restorative material type and the applied cariostatic agent. SDF produced the greatest increases in roughness, especially in LD (∆Ra = 0.232) and FC (∆Ra = 0.126), compared with the control group (p < 0.001), and color-change values far above clinically acceptable thresholds (∆E<sub>00</sub> = 30.56-45.72; p < 0.001). Potassium iodide application after SDF (RS) showed low color change across all restorative materials (∆E<sub>00</sub> = 0.28-0.75) and increased roughness in the FC. NSF showed behavior similar to the control group in terms of roughness and maintained color-change values within acceptable limits (∆E<sub>00</sub> = 0.57-1.35).</p><p><strong>Conclusions: </strong>SDF may compromise the surface roughness and color change of CAD-CAM-milled restorative materials, whereas NSF and RS show potential as more favorable alternatives for the evaluated outcomes.</p>","PeriodicalId":49152,"journal":{"name":"Journal of Prosthodontics-Implant Esthetic and Reconstructive Dentistry","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149117444","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}
