Impact of Two Flap Advancement Techniques and Periosteal Suturing on Graft Displacement During Guided Bone Regeneration.

Objectives: This preclinical ex vivo porcine study aimed to evaluate the effects of two flap advancement techniques and periosteal suturing (PS) on graft material displacement during primary wound closure in guided bone regeneration (GBR). Secondary objectives included assessing flap advancement and the impact of soft tissue characteristics on graft displacement.

Materials And Methods: Standardized two-walled horizontal bone defects were created in second premolar sites of pig hemimandibles.

Reproducibility and Reliability of Intraoral Scanners for Evaluating Peri-Implant Tissues and Implant-Supported Prostheses: A Cross-Sectional Study.

Objective: To assess the reproducibility and reliability of the pink (PES) and white esthetic scores (WES) using digital images and the intra- and inter-examiner agreement among different clinical backgrounds and assessment methods.

Material And Methods: Standardized intraoral images were obtained from adult subjects with an implant-supported single-tooth fixed dental prosthesis located in the maxillary esthetic zone using a digital camera and a true-color intraoral scanner. According to the PES and WES criteria, the images were evaluated by 20 calibrated evaluators, 5 prosthodontists, 5 periodontists, 5 undergraduates, and 5 oral surgeons.

Analysis of trends in the context of implant therapy in a university surgical specialty clinic: a 20-year retrospective study.

Objectives: To analyze the trends in the context of implant therapy in a 3-year patient population and compare it with data obtained over the last 20 years.

Materials And Methods: All adult subjects who received treatment in the context of implant therapy between 2020 and 2022 were included in this retrospective study. Data regarding patient demographics, indications and location of implant therapy, implant characteristics, surgical techniques, complications, and early implant failures were recorded and compared to data obtained in the years 2002-2004, 2008-2010, and 2014-2016.

Primary Stability of Dental Implants in Human Jawbones: Experiments & FE Analyses.

Objectives: Primary stability (PS) is a key factor for promoting osseointegration and long-term success of dental implants particularly for immediate loading protocols. Beyond the current assessments of PS, an accurate pre-operative evaluation of PS would contribute to the improvement of surgical planning and treatment outcome. This study used biomechanical testing and homogenized finite element (hFE) analysis to objectively measure PS in the laboratory, and digitally estimate PS from prior μCT reconstructions.

Homogenized finite element simulations can predict the primary stability of dental implants in human jawbone.

Adequate primary stability is a pre-requisite for the osseointegration and long-term success of dental implants. Primary stability depends essentially on the bone mechanical integrity at the implantation site. Clinically, a qualitative evaluation can be made on medical images, but finite element (FE) simulations can assess the primary stability of a bone-implant construct quantitatively based on high-resolution CT images.
