Objectives: This large-scale retrospective study aims to evaluate and compare the long-term survival rates of dental implants placed immediately after tooth extraction (type 1) versus those placed at a later stage (types 2, 3, and 4). Additionally, it examines how patient characteristics and implant site conditions influence the choice of implant placement.
Materials And Methods: This study retrospectively analyzed patient data from 10 university dental clinics between 2011 and 2022 and examined dental implant treatment outcomes. Patient information, including age, sex, ethnicity, race, smoking, and medical status, was analyzed.
Results: Records of 20,842 patients with 50,333 dental implants inserted between 2011 and 2022 were analyzed. The multivariate analysis resulted in significant differences for age, ethnicity, race, gender, and asthma. A 98.4% survival rate for dental implants placed immediately following extraction and a 98.6% survival rate for those placed in fully healed sockets were recorded. The type of implant placement (immediate vs. delayed) showed no significant effect on implant outcome.
Conclusion: Immediate implant placement resulted in high survival rates with delayed implants inserted into healed sites. Both immediate and delayed implant placements are viable therapeutic approaches demonstrating predictable outcomes.

Adjunct Professor, Department of Dental Medicine, Faculty of Medicine and Dentistry, University of Valencia, Valencia, Spain.
Statement Of Problem: Extraoral photogrammetry (PG) systems can record implant positions in 1 scan or in 2 scans that are then merged. However, the accuracy of implant positions recorded in 2 partial photogrammetry scans is unknown.
Purpose: The purpose of this in vitro study was to compare the accuracy of complete arch implant scans recorded in 1 or 2 scans by using 3 extraoral PG systems.

Objective: This study aimed to evaluate the accuracy and clinical impact of implant placement by novice implant clinicians in the narrow anterior ridge by fully guided (FG), pilot-guided (PG), and freehand (FH) placements.
Materials And Methods: A maxillary surgical model with missing incisors and a narrow ridge was designed. Two implants were planned in the lateral incisor locations to receive screw-retained implant prosthesis.

Electronic address:
With the ongoing advancement of digital technology, oral medicine transitions from traditional diagnostics to computer-assisted diagnosis and treatment. Identifying dental implants in patients without records is complex and time-consuming. Accurate identification of dental implants is crucial for ensuring the sustainability and reliability of implant treatment, particularly in cases where patients lack available medical records.

Purpose: 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.
Methods: 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 submerged group (SM) was classified as defective (SM-BD) and intact (SM-BI).
Advancing Peri-Implantitis Treatment: A Scoping Review of Breakthroughs in Implantoplasty and Er:YAG Laser Therapies.

Department of Periodontics, University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Background: Peri-implantitis represents a significant challenge in dental implantology, characterized by inflammatory reactions around osseointegrated dental implants that lead to progressive alveolar bone loss.
Objectives: To generate a scoping review that evaluates the efficacy of implantoplasty and Er:YAG laser therapies in managing peri-implantitis by synthesizing recent evidence on their impact on key clinical parameters-including probing depth reduction, bleeding on probing improvement, and marginal bone level stabilization-and to explore the potential synergistic benefits of combining these modalities for enhanced treatment outcomes.
Material And Methods: A comprehensive search was conducted in PubMed, EMBASE, the Cochrane Library, and Web of Science for studies published from January 2018 to the present.
