ABSTRACT Objective To evaluate the feasibility of ultrasound‐image‐based computer‐assisted implant planning and placement. Materials Methods Intraoral scans, cone‐beam computerized tomography (CBCT), ultrasound (US) scans with a custom positioning device were acquired in nine patients. Prosthetic‐driven surgical guides planned fabricated based on images intraoral scans. Implants then placed. Postoperative position was obtained intra‐surgically by scan. Aside from ultrasound‐based plan, conventional performed same operator pre‐surgical CBCT for comparison. Linear deviations between CBCT‐planned positions measured compared intra‐surgical position, two consecutive plannings operator. The linear deviation 3D scan surface edentulous region ultrasonographic soft tissue profile segmentation also assessed reverse‐engineering software. Means, standard deviations, root mean square differences (RMSD) calculated every variable.

Abstract Aim To apply high‐frequency ultrasound (HFUS) echo intensity for characterizing peri‐implant tissues at healthy and diseased sites to investigate the possible ultrasonographic markers of health versus disease. Materials Methods Sixty patients presenting 60 implants diagnosed as ( N = 30) peri‐implantitis were assessed with HFUS. HFUS scans imported into a software where first‐order greyscale outcomes [i.e., mean (EI)] second‐order assessed. Other interest involved vertical extension hypoechoic supracrestal area (HSA), soft‐tissue (STA) buccal bone dehiscence (BBD), among others. Results EI values obtained from soft tissue 122.9 ± 19.7 107.9 24.7 grey levels (GL); p .02, respectively. All showed appearance an HSA that was not present in (area under curve 1). The proportion HSA/STA 37.9% 14.8%. Regression analysis significantly different between (odds ratio 0.97 [95% confidence interval: 0.94–0.99], .019). Conclusions characterization shows significant difference sites. presence/absence may be valid diagnostic discriminate status.

ABSTRACT Aim To assess tissue perfusion changes and wound healing biomarker levels after root coverage procedures with coronally advanced flap in combination the cross‐linked xenogeneic collagen matrix (CCMX), loaded either a placebo or recombinant human platelet‐derived growth factor‐BB (rhPDGF). Methods This study was designed as secondary analysis from previously published clinical trial, it assessed over 6 months around multiple gingival recession defects, treated CCMX alone (control) + rhPDGF (test). High frequency Doppler ultrasonography (HFUS) scans were obtained at sites of interest baseline, 2 weeks, 3 months, surgery. Dynamic measurements (DTPMs) performed midfacial, interproximal, transverse aspects teeth by an operator, blinded to treatment allocation, using software package. The expression different biomarkers crevicular fluid also assessed. Results regression analyses showed similar between two groups throughout majority months.

Understanding the available methods to study blood flow in oral cavity can enhance knowledge of research methodology on periodontal circulation related disease initiation and progression as well wound healing. This aims systematically review non-invasive techniques that allow for assessment tissue perfusion clinical pre-clinical studies. A complete electronic literature search 5 databases (NLM PubMed, Embase, EBSCOhost CINAHL, Dentistry Oral Sciences Source, Wiley Cochrane Central Register Controlled Trials) was conducted by two reviewers. The terms included gingival flow, perfusion, imaging soft diagnostic, vascularization, tissue, microvascularization. focused question is: What are quantitative used evaluate perfusion? total 79 articles were qualitative analysis. Various identified, including Laser Doppler Flowmetry (LDF), Speckle Contrast Imaging (LSCI), Spectral Methods (such Diffuse Reflectance Spectroscopy), Ultrasound (US), Intravital Video Microscopy, Videocapillaroscopy. LDF is most applied estimate a small focal area diseases healing, among other indications. LSCI, providing surrogate superficial values 2-dimensional, larger field-of-view, has been similar reasons. use cross-sectional ultrasound rise record velocity volume using color power modes, respectively.

These could potentially augment our ability diagnose monitor healing objectively timely. In combination, these treatment outcomes significantly.
