The aim of this study is to compare the effects of different occlusal forces on quad zygoma, transnasal and pterygoid implants in patients with severely atrophic maxilla using finite element analysis.

Implant-supported single crowns (ISSCs) are a common treatment option for replacing missing teeth in the anterior maxilla. Extensive long-term studies are still needed to report on esthetic qualities, clinical performance, potential complications, and overall patient satisfaction with this treatment.

To compare clinical outcomes of short (6 and 8 mm) and standard-length (11 and 13 mm) implants in posterior sites. It was hypothesized that both implant types exhibit no difference regarding implant survival rate and marginal bone level change (MBLC).

Implant overdenture rehabilitation has recently become a common treatment for patients. However, few papers present long-term observations (over 10 years) of IOD/IRPD. The purpose of this study was to investigate the clinical results of 'planned' IOD/IRPD provided at Tsurumi University Dental Hospital over approximately 20 years, as a retrospective cohort study.

Morse taper connection presents better functional load distribution than other types of connections. The angle and finishing surfaces are used to prevent components from loosening under direct axial load. The angulation of the connection walls for the Morse effect to exist should be from 6° to 16°. Therefore, there is a lack of consensus regarding the most appropriate conical connection from both biological and mechanical perspectives. This study aimed to evaluate the influence of different conicities (10°, 16°, 22°, and 24°) of implants with conical connections on the adhesive wear of the prosthetic abutment after the application of the tightening torque.

Electronic cigarette (e-cig) aerosol encounters all constituents in users' mouths, including soft and hard tissues and dental implants. Deposition of the e-cig aerosols on dental implants can lead to implant failure (peri-implantitis). This study aims to evaluate the effect of e-cig vaping on the interactions of normal and diabetic human fibroblasts with dental implant materials.

The volume and morphology of alveolar bone drives the rehabilitation of edentulous patients. Rehabilitation of the atrophic ridge remains a challenge, both surgically and prosthetically. Commonly, bone grafting procedures, in combination with endosseous dental implants, are necessary. Graftless options, using tilted and/or longer endosseous dental implants placed into pyriform rim, nasal, pterygoid, and zygomatic bone have been developed to treat these problem cases. These options are technique sensitive and can result in increased patient morbidity. Digitally planned, custom milled, and rigidly fixated subperiosteal implants offer removable or immediate fixed options when conventional treatments are contraindicated or fail. Although this new treatment has recently been Food and Drug Administration (FDA) approved, it has been used successfully in Europe for over 10 years with overdenture final prostheses. This case series reports on the treatment of seven severely atrophic maxillae treated with a digitally planned and milled, rigidly fixated subperiosteal implant, restored with a full-arch immediate-load protocol with fixed provisional and definitive (final) restorations.

To evaluate the effect of screw access hole (SAH) presence and location on the marginal and intaglio fit and fracture resistance of zirconia crowns.

This study assessed horizontal and vertical discrepancies in polyetheretherketone implant scan bodies on bone-level tapered and tissue-level implants at varying torque levels using scanning electron microscopy.

To compare the clinical performance of narrow diameter implants (NDIs) to standard diameter implants (SDIs) over a minimum three-year follow-up period, focusing on different anatomical locations and prosthetic designs.

In dental implantology, various techniques are used to support bone healing and enhance osseointegration. One such approach is photobiomodulation (PBM). So, this study aimed to evaluate and compare the effects of 810 nm photobiomodulation (PBM) on post-surgical healing, implant stability, and crestal bone levels surrounding dental implants.

The aim of the present study was to evaluate the use of customized CAD-CAM titanium mesh for the treatment of bone atrophy type V of Cawood and Howell as mean vertical and horizontal bone gain and complications rate.

Alveolar ridge preservation (ARP) aims to minimize alveolar bone resorption after extraction. The benefit of ARP in reducing the need for additional bone augmentation procedures to facilitate implant placement has been demonstrated, particularly in single-rooted tooth sites. However, its efficacy in molar sites remains unclear. This systematic review aimed to investigate if ARP in molar sites, compared to spontaneous healing (SH), adequately preserves ridge dimensions to facilitate successful implant placement while reducing the need for additional bone augmentation procedures such as guided bone regeneration (GBR) or sinus floor augmentation (SFA).

This retrospective study aimed to assess the clinical outcomes of simultaneous implant placement using the lateral sinus floor elevation without bone graft (LSFEWoG) combined with the osseodensification (OD) technique.

Titanium ions and particles (TiP) are associated with localized inflammatory response and may play a role in further peri-implant tissue breakdown.

To evaluate and compare the influence of osseodensification (OD) and conventional drilling (CD) techniques on primary and secondary implant stability. The study also compares the effect of these techniques on peri-implant bone density, crestal bone level, alveolar ridge width, and concentration of TNF-α and IL-1β.

To compare the survival, success rate, and technical complications of two immediately loaded fixed prosthetic designs- full-arch ceramic prostheses and full-arch Toronto bridges- at a 10-year follow-up.

This study aimed to retrospectively evaluate the influence of systemic factors on postoperative complications and osseointegration of zygomatic implants over a follow-up of up to 12 years, and to investigate whether implant surface characteristics affect the incidence of complications.

Preoperative evaluation of the maxillary sinus is essential for planning sinus augmentation procedures. Chronic sinusitis and aspergillosis are considered contraindications, yet current guidelines recommend cone-beam computed tomography (CBCT) imaging only for symptomatic patients. This study aimed to determine the prevalence of sinus pathologies in patients scheduled for sinus augmentation and to evaluate the necessity of routine preoperative CBCT imaging.

To determine whether lateral sinus floor elevation (LSFE) through a less-invasive window design (LIWD) can achieve (1) adequate sinus augmentation and (2) a safe procedure with reduced patient discomfort compared to a large window design (LWD).
