Material methods: Forty‐five patients, 20 males 25 females, aged 20–66 years, affected by edentulism associated horizontal resorption ridges, were treated means sagittal osteotomy expansion ridge with obtain wider bony base for ideal implant placement....

The aim of this study was to assess the accuracy digital impressions for "all-on-four" implant rehabilitation.Patients edentulous in one or both jaws were randomly selected study. Complete arch immediately loaded prostheses supported by 4 implants (2 axial and 2 tilted) placed. Five hours after placement, screw-retained full-arch temporary positioned. After months, a scan body used finalize definitive prosthesis. Radiographic assessments obtained surgery at each follow-up visit. Bone level...

The present study was conducted to investigate whether a different implant neck design could affect survival rate and peri-implant tissue health in cohort of disease-free partially edentulous patients the molar-premolar region. investigation on 122 dental implants inserted 97 divided into two groups: Group A (rough wide-neck implants) vs. B reduced-neck implants). All were monitored through clinical radiological checkups. Survival rate, probing depth, marginal bone loss assessed at 12-...

(1) Background: Computer-guided surgery is now established as the main technique for implant placement, reducing intraoperative complications and helping clinician avoid damaging sensitive anatomical structures, such as, example, maxillary sinus. (2) Methods: A complex case discussed to suggest how computer-aided can merge with freehand surgery, a surgical guide make procedure less complicated more predictable. (3) Results: was executed following digital planning, except sites 1.5 2.5, where...

(1) Background: Since new intraoral scanner (IOS) versions are introduced to the market and software continues advance, there is an ongoing need assess accuracy of newer IOS models. (2) Methods: Four types IOSs one laboratory (used as a reference) were used scan edentulous model with six parallel implants their respective bodies, which connected each other. Using dedicated software, distances between all bodies calculated, generating total 540 measurements. Trueness (comparisons reference...

Intraoral digital impression is a viable alternative to conventional techniques and has been proven be even more accurate than materials. Nevertheless, there are cases in which the rheologic properties of materials can helpful. This article describes method overcome an insufficient sulcus-depth reading intraoral scanners challenging cases.

Objectives . The aim of the study was to evaluate and compare digital traditional prosthetic workflow for posterior maxillary restorations supported by an upright a distally tilted implant at 3-year follow-up. Materials Methods Twenty-four patients were treated in maxilla with 24 immediately loaded axial implants supporting 3-unit or 4-unit screw-retained prostheses. Three months after initial loading randomly stratified into two groups: definitive impressions carried out control group,...

The aim of this study was to evaluate and compare two different techniques for the treatment plaque-induced gingivitis, demonstrating whether causal therapy supported by diode laser can allow a resolution edema caused gingivitis in less time compared single traditional therapy.

Periodontal disease poses a significant global health challenge. Traditional treatments focus on reducing inflammation and bacterial load, yet novel approaches are continually being investigated. Recent research suggests that IL-37, potent anti-inflammatory cytokine, may play crucial role in modulating the inflammatory processes associated with periodontal disease. In conjunction low-level laser therapy (LLLT) has gained attention for its potential promoting tissue repair, inflammation,...

Abstract Objectives The aim of this study was to evaluate the clinical performance and possible complications single zirconia crowns fabricated using an intraoral digital computer-aided design-computer-aided manufacturing (CAD-CAM) protocol in normal dysfunctional patients after 3 years follow-up. Materials Methods Seventy were included study. teeth prepared with a knife-edge marginal design, temporary placed. Digital impressions taken optical scanning, frameworks milled same technology....

Aim. The purpose of this study is to evaluate the success a new Three-Dimensional CAD/CAM processing technique in Full-Arch Implant Supported Rehabilitation edentulous patients.
