Six replicas each three systems different design were placed in polyurethane foam block densities(soft, medium hard) via two preparation protocols (normal undersized preparation) at depths (3 mm, 5 mm 7 mm). The was recorded subsequently analyzed using one-way four-way ANOVA. Prediction models then constructed multiple linear regression (MLR) tree (DTR) analyses multi-factors. These evaluated compared their predictive accuracy performance. influencing factors immedate are ranked as follows: quality, depth, protocol, design. Both preoperative prediction (MLR DTR) showed high prediction, latter's R2 reaching 0.951. research is significant reference value optimizing clinical decision-making, placement, enhancing efficiency doctor-patient communication.

Introduction: Osseodensification is a non-extraction technique using specially designed drills to increase bone density while extending an osteotomy, allowing be preserved and condensed by compacting autograft during osteotomy preparation, increasing around implants, improving mechanical stability. Aim: The objective of this study compare conventional osseodensification protocols in implant placement analyze whether there are differences density.

Methods: analysis evaluated patients American Society Anesthesiologists grade I or II, >20 years, alveolar bone volume suitable for placement, who received immediate delayed placement after extraction, (n = 57) Toplan 87) implants. The insertion torque value (ITV) measured on day quotient (ISQ) 1 month post-surgery, 2–3 months implantation were analyzed. Results: Both implants had significantly increased ISQs over time, did not differ between at any time point. showed higher in D2 than D3 bone, mandible maxilla all points. diameters >4.0 mm initial ISQs. a significant correlation ITV ISQ (r 0.349, p < 0.01) but later For implants, no was confirmed At follow-up, still providing functional service.

Published: Feb. 1, 2025

ABSTRACT Background Dental implant materials, designs as well general concepts for surgical techniques have evolved during the last decades. It has been validated that primary stability followed by bone apposition around implants is crucial survival most failures occur first year. However, new materials and different micro macro improved in more challenging clinical conditions. Therefore, research with large patient groups needed to investigate effects of protocols aim improve early outcomes. Purpose The purpose study use dental designs, related complications failures. Materials Methods All patients who had received surgery 2007 2017 at three specialist centers Sweden were identified using charge codes. Data retrieved from a record system digital analog registries on surgeries. Information anamnestic data, status, techniques, year was compiled analyzed. Descriptive statistics used comparison time cohorts. data statistically analyzed multivariable logistic regression model significance level p < 0.05 dependent variables.

Abstract Objectives The objective of this retrospective study was to investigate the impact bone-related factors such as initial bone height (IBH), imaginary pixel unit (IPU), diameter (BD), crestal cortical thickness (CCT), and sinus floor (SFT) in transalveolar lift procedures using threaded expanders without graft materials. Materials methods This cohort carried out on patients who had reported department oral maxillofacial surgery at Tishreen University between January 2018 June 2024. sample consisted motorized with simultaneous hybrid dental implants placement factors, including were analyzed CBCT scans that taken preoperatively. Statistical analysis performed assess relationship insertion torque implant. statistical includes descriptive statistics for all variables mentioned. A Uni-variate linear regression (Spearman’s correlation) multivariate relation Insertion explanatory variables. p values < 0.05 considered be statistically significant.

Dental implants are now a standard oral surgery procedure for humans; in veterinary dentistry, there is still need more information about these medical devices used to replace missing teeth. Advances human implantology have informed studies on the insertion and osseointegration of dental dogs, but it needed study prosthodontic stage. Additionally, few been published regarding cats, often lacking long-term results. Case reports that support use dentistry already published, covering short-, medium-, outcomes. Therefore, specialists must collaborate establish protocols ensure predictable success this field. This chapter discusses case selection, methods, complications, outcomes related small animals.
