We compared three procedure pathways and examined whether tongue-coating reduction mediates procedure-related improvement. <b>Methods:</b> A prospective cohort of 94 patients aged 65 years or older was assigned by dominant indication to periodontal debridement with tongue cleaning (PDT, <i>n</i> = 33), denture biofilm management (DBM, <i>n</i> = 31), or restorative/prosthetic maintenance (RPM, <i>n</i> = 30). This was a single-center, nonrandomized prospective cohort study; assignment followed the dominant clinical indication rather than randomization. All clinical assessments were made by a single examiner who was masked to the formal procedure-group assignment; masking was partial because the clinical picture at follow-up could sometimes reveal the care delivered. The primary outcome was percentage reduction in volatile sulfur compound (VSC) concentration at 8 weeks. Secondary outcomes included organoleptic score, HALT, OHIP-14, tongue-coating index, denture plaque index, and a composite clinical response (≥30% VSC reduction plus ≥ 1-point organoleptic improvement plus ≥ 8-point HALT improvement). Linear mixed-effects, multivariable regression, and bootstrap mediation analyses were performed. <b>Results:</b> All three procedures reduced VSC at 8 weeks, but PDT produced the largest absolute reduction (-102.6 ± 20.2 ppb) and the highest composite response rate (57.6%), versus 9.7% in DBM and 3.3% in RPM (<i>p</i> < 0.001).

Despite high reported survival rates, their placement is technically demanding because of the complex anatomy of the pterygomaxillary region and the proximity of critical neurovascular structures. Implant displacement into adjacent deep anatomical spaces is a rare but potentially serious complication. The aim of this report is to describe the management of sequential intraoperative complications involving pterygoid implants-initial migration into the maxillary sinus followed by displacement into the pterygopalatine fossa-and to analyse the technical factors that contributed to them. <b>Case Description</b>: A 68-year-old woman underwent full-arch maxillary rehabilitation with eight implants, including bilateral pterygoid implants. Both pterygoid implants showed progressively decreasing primary stability and migrated into the maxillary sinus. During a salvage attempt, a newly inserted pterygoid implant deviated and was displaced beyond the pyramidal process into the pterygopalatine fossa together with the insertion driver. Cone-beam computed tomography (CBCT) localized the implant-lying medial to the lateral pterygoid plate, anterior to the pterygoid process-and guided a targeted retrieval based on careful blunt dissection, performed in an outpatient setting without general anesthesia or endoscopic assistance. A correctly positioned pterygoid implant was then placed. The anterior implants (insertion torque > 60 N·cm) were immediately loaded; at four months the right pterygoid implant was uncovered, and the left implant retained in the sinus was retrieved and replaced using a trans-sinus technique with elevation of the Schneiderian membrane. <b>Conclusions</b>: This case highlights the importance of accurate, consistent anatomical localization, complete osteotomy preparation, appropriate implant selection, and controlled, torque-monitored insertion during pterygoid implant placement.

Virtual interocclusal records at MIP were obtained with an intraoral scanner at three dental chair backrest inclinations (90, 120, and 180 degrees). Conventional vinyl polysiloxane interocclusal records were made at the same inclinations. All scans were printed into physical models and mounted using the conventional records. Digitized casts and intraoral scans were superimposed onto a single common reference, the virtually mounted 90-degree scan, using metrology software. Because all deviations were expressed relative to that reference, the virtual 90-degree condition is zero by construction and was excluded as a data level from inferential models. Separate linear mixed-effects models were fitted for each translation and rotation axis, with participant as a random intercept and recording method, inclination, and their interaction as fixed effects; &lt;i&gt;p&lt;/i&gt; values were Holm-adjusted across the six axes. Equivalence was explored with two one-sided tests against margins of ±0.5 mm and ±1.0 degrees; because these margins were specified post hoc, the equivalence analysis is exploratory. &lt;b&gt;Results&lt;/b&gt;: Chair inclination did not detectably affect either recording method: no inclination main effect or method × inclination interaction survived multiplicity correction, and virtual records at 120 and 180 degrees differed by no more than 0.05 mm and 0.08 degrees. Recording method did differ. Conventional records were displaced relative to virtual records by 0.27 mm along the Y axis (95% CI 0.19 to 0.34; Holm-adjusted &lt;i&gt;p&lt;/i&gt; &lt; 0.001), in the same direction in 9 of 10 participants.
