Background/Objectives: Immediate provisionalization in the esthetic zone is a well-documented but technique-sensitive procedure, and the choice of provisional connection geometry (indexed vs. non-indexed) remains debated. The aim of this ret-rospective single-arm cohort clinical study was to evaluate the clinical performance of a digitally planned, guide-delivered provisionalization protocol using prefabricated provisional crowns connected to 5-degree Morse taper implants without an antirota-tional index, with emphasis on emergence profile shaping and peri-implant tissue sta-bility at one year; Methods: Twenty consecutive single-implant cases (19 female, 1 male; mean age 38.1 ± 12.7 years; 18 anterior and 2 premolar sites) were treated between January 2024 and February 2026. All implants were placed with primary inser-tion torque ≥ 30 N·cm (mean 34.75 ± 2.55 N·cm) and immediately restored with a digitally designed, non-antirotational provisional crown. Primary outcome was provision-al retention without major intervention; secondary outcomes included biologic com-plications, papilla score, marginal bone change at T0–T3 and T3–T4, and buccal con-tour change (T0 vs T2 intraoral scan superimposition). Wilson 95% confidence inter-vals, Fisher’s exact test, and Mann–Whitney U test were used (α = 0.05); Results: Pro-visional retention without major intervention was 75.0% (15/20; 95% CI 53.1–88.8). Biologic complications were uncommon (bleeding on probing, suppuration, midfacial recession, and chairside adjustment, each 5.0%). Mean total marginal bone loss at one year was 0.37 ± 0.20 mm; mean buccal contour gain was 1.41 ± 0.48 mm. A complete papilla was preserved in 70.0% of cases; Conclusions: Digitally planned, guide-delivered provisionalization on a non-antirotational 5-degree Morse taper interface appears clinically feasible for emergence profile shaping in the esthetic zone, with stable peri-implant tissues at one year.

Psoriasis is a chronic immune-mediated inflammatory disorder increasingly recognized as a systemic disease, yet the clinical significance and underlying mechanisms of its oral manifestations remain incompletely understood. Building on previous reviews, this narrative review provides an updated synthesis of the clinical spectrum and pathogenic mechanisms of oral involvement in psoriasis, with particular emphasis on the specificity and strength of reported associations, conflicting evidence, pediatric presentations, and differential diagnosis. The relevant literature was identified through searches of PubMed, Scopus, and Web of Science. Geographic tongue and fissured tongue are the most consistently reported oral findings, whereas geographic stomatitis, palatal involvement, and psoriatic cheilitis are less common. Histopathological, immunological, and genetic findings suggest overlapping mechanisms between cutaneous psoriasis and selected oral conditions, particularly involving IL-17/IL-23-related inflammatory pathways; however, most oral findings are not specific to psoriasis. Evidence supports an association with poorer periodontal health, whereas the relationship with oral malignancy remains inconsistent. Particular attention is given to pediatric oral involvement, differential diagnosis, and areas in which observational or case-based evidence limits clinical interpretation. Oral lesions should therefore be interpreted within the broader clinical context and alternative inflammatory, infectious, traumatic, and nutritional causes considered. Further prospective and longitudinal studies are needed to clarify the diagnostic, prognostic, and therapeutic significance of oral findings in psoriasis.
