The aim of this study was to investigate the superimposition of CBCT data with virtual models of the oral situation directly generated using an IOS and with indirectly generated plaster models. Two different radiopaque jaw models were first scanned using a CBCT unit. Secondly, ten scans using an IOS and ten alginate impressions were made. The alginate impressions were cast with...
The aim of this study was to evaluate the marginal bone loss (MBL) over a follow-up period of up to 36 months in Immediate dental implants (IDIs), as well as the impact of various clinical variables on the MBL. IDIs placed in two surgical phases were evaluated. Implants were classified into bone loss (BL, exposed threads), bone remodeling (BR, crestal bone at the implant margin...
This study aimed to compare the accuracy of immediate implant placement (IIP) with different implant macrogeometry using a dynamic navigation in the maxillary aesthetic zone. Seventy-six extraction sockets in the maxillary aesthetic zone from nineteen partially edentulous models were randomly divided into four implant system groups with different macrogeometry: non-progressive...
The aim of this study was to investigate the effect of different bone graft hydration times on bone regeneration. Five-mm defects were created on either side of the sagittal plane in the calvaria of 40 rats. In each rat, the right and left defects were filled with allograft (Cenobone®) and xenograft (Cerabone®) particles, respectively, based on the grouping that was randomly...
The aim of this study was to investigate the performance of a novel 3D-printed cooling system for drilling templates during fully guided implant insertion. Dental implant tunnel preparations were performed for the Straumann Bone Level implant in a 3D-printed synthetic resin model using either conventional guided or modified 3D-printed guided (with a cooling channel leading...
To compare cone-beam computed tomography (CBCT) with photon-counting detector computed tomography (PCD-CT) at equivalent radiation doses, focusing on qualitative and quantitative parameters relevant to dental implant surgery. This ex vivo comparative study of porcine specimens assessed five imaging protocols with both CBCT and PCD-CT at three effective radiation dose levels (high...
To retrospectively assess the potential impact of biological and host factors on radiographic bone loss following tissue-level implant placement and prosthetic rehabilitation. The University database was reviewed to identify patients treated with tissue-level implants between 2006 and 2020 at the University of Zurich, Switzerland. The study included patients who received screw...
This study assessed the impact of the buccal bone on hard and soft tissues in submerged and non-submerged immediate implants using a minipig model. Sixty-five titanium implants (Camlog Progressive Line) were placed in four minipigs immediately after tooth extraction. All non-submerged (NSM) implants received a mechanically induced buccal bone defect (NSM-BD), whereas the...
Implant therapy in the advanced atrophic jaw remains challenging in oral and maxillofacial surgery. Hence, a plethora of different augmentation procedures to increase bone volume in the maxilla and mandible have been published. Horizontal vascular-stalked split osteotomy (HVSO) represents a safe and effective approach for the three-dimensional jaw augmentation since it combines...
The primary aim of this in vitro study was to investigate the primary implant stability obtained in immediate and late implant placement scenarios. Secondary aims evaluated the effect of two distinct implant macro-designs and examined the correlation between resonance frequency analysis (RFA) and final insertion torque. Partially edentulous maxillary models including six single...
The aim of this retrospective study was to investigate and compare the effects of platform switching (PS) and platform matching (PM) on marginal bone loss (MBL) and clinical parameters in immediately inserted dental implants. Thirty-seven patients were included (PS group: twenty-one patients, PM group: sixteen patients), with follow-up periods ranging from six months to 23 years...
A case of postoperative mandibular defects was successfully managed using an intraoral scanner and computer-aided design/computer-aided manufacturing (CAD/CAM) technology, facilitating jaw reconstruction and functional restoration with implants for a critical mandibular defect. The intraoral scanner was used to scan the maxilla and mandible, and occlusal scans were acquired. The...
Silk fibroin (SF) is a biomaterial derived from the cocoon of the mulberry silkworm. This study aimed to assess the capacity of SF matrices biologized with injectable platelet-rich fibrin (iPRF) or enamel matrix protein (EMP) to modulate angiogenesis and immune response in the chorioallantoic membrane (CAM) assay. 300 eggs were divided into the following groups: CM + NaCl, CM...
Peri-implantitis is known as an inflammatory condition affecting the soft and hard tissue around dental implants. A promising strategy to prevent these conditions is the use of antibacterial implants. This study aimed to evaluate the antibacterial potential of titanium (Ti) dental implants modified using plasma-electrolytic oxidation (PEO). The modified surfaces were subsequently...
The aim of this study was to investigate in-vitro the temperature changes occurring in the bone during drilling with implant drills manufactured by different companies. Bone blocks obtained from fresh bovine ribs were used in the study. Bone blocks were drilled with drills manufactured by Ankylos, Astra Tech, Nobel Biocare, Bredent and Straumann implant brands at an ambient...
Dental implant systems provide standard cylindrical healing abutments of various diameters; however, they do not match the larger shape of the complex emergence profile of the prosthetic crowns. Adaptation of the soft tissues from a circular emergence profile to the one that suits the prosthetic crown involves a simultaneous squeezing and stretching of the gingiva. Often, this...
To retrospectively evaluate the outcome of implant-supported or combined tooth-implant-supported prostheses retained by electroplated double-crowns after 1–12 years. Twenty-five patients were retrospectively examined in a private dental practice in Hamburg, Germany. All had been rehabilitated with a removable prosthesis retained by electroplated double-crowns, for at least one...
Between adjacent dental implants, an interimplant distance (IID) of at least 3 mm has been recommended to avoid resorbing the interproximal crestal bone. The effect of a 2 mm IID on crestal bone loss has been investigated but the literature is scarce when it comes to an IID of 1 mm. There is a need to document such clinical situations when they occur and elucidate if such a...
The study aimed to examine the usefulness of a novel density measurement drill for evaluating cancellous bone density by examining the correlation between computed tomography (CT)-based Misch bone density classification and drilling torque value. Bovine ribs were used as the drilling sites for implant placement. Multidetector CT (MDCT) was performed after contrast materials were...
The study assessed the clinical outcomes following treatment of peri-implant mucositis using Er:YAG laser or an ultrasonic device over six months. Patients
This systematic review aims to assess the performance, methodological quality and reporting transparency in prediction models for the dental implant’s complications and survival rates. A literature search was conducted in PubMed, Web of Science, and Embase databases. Peer-reviewed studies that developed prediction models for dental implant’s complications and survival rate were...
This study aimed at investigating implant survival rate and marginal bone loss (MBL) around extra-short implants. The impact of the loading protocol and of the use of an intermediate abutment was also evaluated, to explore possible differences in terms of the outcome measures. Patients with single or multiple mandibular or maxillary posterior edentulism rehabilitated using extra...
SLM 3D printing technology is one of the most widely used implant-making technologies. However, the surfaces of the implants are relatively rough, and bacteria can easily adhere to them; increasing the risk of postoperative infection. Therefore, we prepared a near-infrared photoresponsive nano-TiO2 coating on the surface of an SLM 3D-printed titanium alloy sheet (Ti6Al4V) via a...
In this randomized clinical trial, we examined the incorporation of nanogold particles into polymethyl methacrylate denture bases and compared these modified bases with conventional ones in mandibular implant-retained overdentures, focusing on microbiological growth and adhesion characteristics. In this study, twenty-two male patients who were completely edentulous participated...
