Purpose: The purpose of this study was to compare marginal bone loss and success rates 1 year after implants had been placed in maxillary molar sites, either immediately postextraction or after the extraction sites had healed (delayed).
Materials And Methods: A retrospective case study was made of subjects treated with immediate or delayed dental implants in the maxillary molar region between January 2006 and December 2008. A protocol was prepared in which patient age, sex, implant length and diameter, type of prosthesis, buccal plate width, and use of bone grafting were recorded. After 12 months, data relating to the clinical and radiologic conditions of the implants and the success rate according to the criteria of Buser et al were recorded. The variables were analyzed statistically (Student t test, Pearson correlation, Games-Howell test).
Results: The study included 123 implants placed in 70 patients; 35 implants were immediate and 88 were delayed. Two immediate and six delayed implants failed, resulting in success rates of 94.3% and 93.2%, respectively. Average marginal bone loss was 0.56 mm for immediate implants and 0.67 mm for delayed implants.
Conclusions: The placement of immediate implants in maxillary molar sites achieved similar results to implants placed in healed sites in the same region after 12 months. No statistically significant differences were found between implant survival rates or average marginal bone loss.

Department of Orthodontics and Dentofacial Orthopedics, 251 Hellenic Air Force & VA General Hospital, Athens, Greece.
Objective: The aim of the current study was to examine possible associations between gingival thickness and other parameters, such as crown length and width, papilla height and patient's age and gender.
Overview: This cross-sectional study included 238 consecutive white Caucasian consecutive patients in all stages of orthodontic treatment (before, in-course, and after orthodontic treatment). Measurements of gingival thickness were carried out at both central mandibular incisors, mid-facially on the buccal aspect of each tooth, and 2 mm apically to the free gingival margin, with an Ultrasound device.
Predictive Factors of Dental Implant Failure: A Retrospective Study Using Decision Tree Regression.

Introduction: Dental implants are routinely used to replace missing teeth. Therefore, the primary aim of the present study was to assess the single-unit implant failure rate over a period of seven years from 2015 to 2021, with a minimum of two years post-implant follow-up. The secondary aim was to identify the risk factors associated with implant failure using machine learning decision tree regression and Kaplan-Meier survival analyses.

This technique is indicated where there is a good amount of keratinized tissue lateral to the defect and deep vestibule. In this case report, a 27-year-old male patient was referred to a periodontal surgery clinic for the management of an 8 mm buccal recession with loss of keratinized tissue related to auto-transplanted maxillary molar that caused discomfort to the patient.

Dental implant placement in the esthetic zone is associated with challenges for clinicians. The best esthetic outcome of this procedure can be obtained through precise management of hard and soft tissue. Orthodontic forced eruption (OFE) has presented an alternative approach to augment hard and soft tissues, which can be applied rapidly or slowly.

Background: Careful anatomical investigation of canalis sinuosus (CS) is essential to prevent damage to blood vessels and nerves in this area during surgical procedures, such as placing dental implants in the anterior maxillary region. This study investigated the relationship and distance between the CS and its adjacent structures.
Methods: A total of 400 cone-beam computed tomography (CBCT) images of Iranian adults aged 20-86 years were included in this retrospective study.
